Water Filtration FAQs

Reverse Osmosis (RO) uses pressure to move water through a semipermeable membrane. The membrane separates much of the dissolved material from the treated water, while a reject stream carries concentrated contaminants away. Performance depends on the system, membrane condition and incoming water.

A correctly configured and maintained Reverse Osmosis system can reduce many dissolved salts and selected contaminants, including fluoride and certain metals. The precise reduction rates depend on the system and independent testing; consult the relevant Pure Water Systems product performance information for specific claims.

Reverse Osmosis membranes can substantially reduce fluoride in drinking water. Actual reduction varies with the membrane, feed-water conditions and system maintenance. Check the relevant RO-5U or EcoHero Reverse Osmosis testing before quoting a percentage.

Reverse Osmosis is among the treatment technologies used to reduce a range of PFAS compounds. Results vary by PFAS type, membrane and system configuration, so any claim for an individual Reverse Osmosis product should be supported by its test data.

Reverse Osmosis reduces many dissolved minerals as well as unwanted substances. Some customers prefer this taste, while others choose a compatible remineralisation stage. The suitability of a remineraliser depends on the system and the desired water characteristics.

The RO-5U Reverse Osmosis System from Pure Water Systems is designed for homes connected to town water, while the EcoHero Reverse Osmosis System offers solutions suitable for both town water and rainwater tank supplies.

Both systems provide advanced drinking water purification, but the best choice depends on your water source, filtration needs, available installation space and household requirements.

Yes, but tank water may need sediment filtration, disinfection or other pretreatment before the Reverse Osmosis system. Pure Water Systems currently directs tank-water enquiries towards compatible EcoHero Reverse Osmosis configurations rather than assuming a town-water RO-5U setup will suit.

Conventional Reverse Osmosis systems produce a concentrated reject stream as part of membrane treatment. The amount varies with the system design, pressure and incoming water quality. Check the specific model for its stated recovery or wastewater ratio.

Permanently installed under-sink systems should be installed by an appropriately licensed professional in accordance with local plumbing requirements and the manufacturer’s instructions. Confirm installation inclusions before purchasing.

Prefilters and postfilters have their own service schedules, while the Reverse Osmosis membrane may have a different lifespan. Follow the schedule for your exact model and replace components earlier if water quality, pressure or performance indicates a problem.

The best choice depends on your water supply, contaminants of concern, installation space and budget. A carbon-based filter may suit taste and chlorine concerns, while Reverse Osmosis may be preferable for broader dissolved-contaminant reduction. Use the Pure Water Systems Water Filter Finder or speak with the team for guidance.

A water filter and a reverse osmosis system both improve drinking water quality, but they work differently and target different contaminants.

A standard drinking water filter typically uses activated carbon or specialised filter cartridges to reduce chlorine, unpleasant tastes and odours, sediment and certain chemicals.

More advanced filters, such as the HTO+ filtration technology used by Pure Water Systems, can also reduce contaminants including selected heavy metals, PFAS and microplastics, as demonstrated by independent testing.

You can explore the results in our HTO & HTO+ Performance Centre at https://purewatersystems.com.au/pages/contaminants-removal, which provides contaminant reduction performance information.

A reverse osmosis system takes water purification a step further. It uses multiple filtration stages, including a specialised reverse osmosis membrane, to reduce a broader range of dissolved substances. This makes reverse osmosis particularly useful for households concerned about fluoride, dissolved salts, nitrates, heavy metals and other contaminants targeted by the system.

Which is better for your home?

Choose a drinking water filter if your main concerns are chlorine, taste, odour, PFAS or other specific contaminants that the selected cartridge has been tested to reduce.

Consider reverse osmosis if you want more comprehensive drinking water purification, particularly for dissolved contaminants such as fluoride and nitrates that conventional carbon filters may not effectively reduce.

What if you're renting or have limited kitchen space?

Renters don't have to miss out on advanced drinking water filtration. Pure Water Systems offers portable benchtop water filters that connect to compatible kitchen taps without permanent plumbing modifications. These compact systems are ideal for apartments, rental properties and smaller kitchens, taking up relatively little bench space and allowing you to take your filter with you when you move.

Portable reverse osmosis systems are also available, offering renters access to more comprehensive water purification without permanent installation. However, they are generally larger than standard benchtop water filters and require considerably more kitchen bench space.

If space is limited, a compact benchtop water filter may be the more practical choice. If reducing dissolved contaminants such as fluoride is your priority, a portable reverse osmosis system may be worth considering despite its larger footprint.

The best option depends on your water supply, the contaminants you want to reduce, your available space and whether you own or rent your home.

The main difference between single and twin under-sink water filters is the number of filter cartridges they contain and the filtration options they provide.

A single under-sink water filter uses one cartridge to treat your drinking water. Depending on the cartridge selected, it can reduce chlorine, unpleasant tastes and odours, sediment and other specific contaminants. Single systems are a practical option for households wanting effective drinking water filtration in a compact design.

A twin under-sink water filter uses two cartridges, allowing different filtration technologies to work together. For example, the first cartridge might target a particular contaminant, such as fluoride, while the second provides additional filtration for chlorine, selected chemicals and other substances.

What are the benefits of a twin water filter?

More filtration options: Two cartridges allow different water quality concerns to be addressed within one system.

Specialised filtration: You can combine cartridges designed for different contaminants.

Greater flexibility: Cartridge combinations can be selected to suit your water supply and filtration priorities.

Is a twin filter always better than a single filter?

Not necessarily. A high-performance single cartridge may be more suitable than a twin system fitted with cartridges that don't address your particular concerns.

The most important factor is what each cartridge is designed and independently tested to reduce, rather than simply how many cartridges the system contains.

Pure Water Systems offers single and twin under-sink water filtration systems, with cartridge options to suit different Australian water supplies and household needs.

Pure Water Systems' advanced HTO+ filtration technology is designed to reduce a wide range of unwanted contaminants in drinking water, including certain PFAS chemicals and heavy metals such as lead.

Unlike basic water filters that primarily target chlorine, taste and odour, HTO+ offers more comprehensive filtration while retaining the convenience of a standard drinking water filter.

Want to know exactly what your filter can reduce? Explore our HTO & HTO+ Performance Centre at https://purewatersystems.com.au/pages/contaminants-removal to see the independently tested contaminant reduction results and learn more about the performance of our filtration technology.

The level of reduction varies depending on the contaminant and cartridge tested, so we recommend checking the performance data when choosing the right filter for your home.

Pure Water Systems' advanced HTO+ filtration technology is designed to reduce a wide range of contaminants commonly found in drinking water, including certain PFAS chemicals and heavy metals such as lead.

Standard activated carbon water filters are not generally effective at reducing fluoride in drinking water. However, there are specialised filtration cartridges and reverse osmosis systems designed specifically to target fluoride.

Pure Water Systems offers a dedicated 10-inch Fluoride Defence cartridge that can be incorporated into a compatible drinking water filtration system. We also offer a Twin Fluoride + HTO+ Benchtop Water Filter, which combines two specialised filtration stages. The first targets fluoride, while the second uses our advanced HTO+ technology to reduce chlorine, selected chemicals, heavy metals and other contaminants.

This twin benchtop option is particularly convenient for renters, apartment living or households wanting fluoride reduction without permanent plumbing modifications. It connects to a compatible kitchen tap and can be taken with you when you move.

For households seeking the most comprehensive drinking water purification, reverse osmosis is generally the preferred option. A reverse osmosis system uses a specialised membrane to reduce fluoride alongside a much broader range of dissolved contaminants, including heavy metals, nitrates and dissolved salts.

If your home has sufficient installation space, reverse osmosis offers a more comprehensive approach to fluoride reduction and overall drinking water purification than a specialist fluoride cartridge alone.

The best choice depends on your water supply, available space, whether you own or rent your home, and the contaminants you want to reduce. Pure Water Systems can help you choose between a dedicated fluoride cartridge, a portable twin benchtop system or a reverse osmosis water purifier to suit your household.

Quick Change systems use a cartridge format designed to make routine replacements more convenient. The initial under-sink installation still needs to comply with applicable plumbing requirements. Check which replacement cartridge fits your specific model.

Some Pure Water Systems under-sink systems are designed for tank-water applications, but others are town-water only. Tank water may require additional sediment or microbiological treatment. Check the product’s stated supply compatibility.

Replacement intervals depend on cartridge type, water quality and usage. Follow the product-specific schedule and replace sooner if flow, taste or other performance changes warrant investigation.

A benchtop filter sits on the counter and typically connects to a compatible tap using a diverter. It treats water at the point of use without requiring a permanent under-sink installation.

Many benchtop systems suit renters because they can be installed without permanent plumbing changes and moved to another property. Check tap compatibility and your rental conditions before installation.

Many Pure Water Systems benchtop models are designed for user installation on compatible taps. Follow the supplied instructions and do not force fittings or modify plumbing where a licensed professional is required.

Compatibility depends on the tap outlet, aerator threads and available adaptors. Pull-out, spray and some specialty mixer taps may not be suitable. Check photos and measurements with Pure Water Systems before ordering.

Yes! One of the biggest advantages of Pure Water Systems' benchtop water filters is that they're completely portable, making them ideal for renters, apartment living and anyone who moves home regularly.

Unlike permanently installed under-sink filtration systems, our benchtop filters connect directly to a compatible kitchen tap without requiring permanent plumbing modifications.

When it's time to move, simply disconnect your filter, pack it securely and take it with you to your new home. You can reconnect it to a compatible tap and continue enjoying filtered drinking water without having to purchase a new system.

This portability also makes benchtop water filters a great long-term investment for renters, as your water filtration system moves with you rather than staying behind at the property.

Just check that your new kitchen tap is compatible with the filter connection before reinstalling it.

Benchtop filters are visible and often portable, while under-sink systems are plumbed in and keep most components concealed. Cartridge technology, not location alone, determines contaminant reduction.

This Pure Water Systems portable twin system combines a fluoride-focused activated-alumina stage with an HTO+ advanced filtration stage. Each stage addresses different treatment goals. Actual performance depends on cartridge testing and operating conditions.

The twin benchtop system is a portable, cartridge-based option targeting fluoride and other selected contaminants. Reverse Osmosis uses a membrane and can reduce a broader range of dissolved salts and constituents. They are not equivalent technologies.

Yes! Pure Water Systems offers benchtop water filters specifically designed for homes using rainwater tanks, so you can enjoy filtered drinking water even if you're not connected to town water.

Our tank water benchtop filtration systems use a dedicated tank water cartridge designed to address the different filtration needs of rainwater supplies. This helps reduce sediment, unwanted tastes and odours, and other contaminants targeted by the cartridge.

Benchtop filters are also a convenient choice for homes where under-sink installation isn't practical. They connect directly to a compatible kitchen tap, require no permanent plumbing modifications and can easily be disconnected and moved if needed.

It's important to remember that rainwater tank quality can vary depending on your roof, gutters, tank maintenance and surrounding environment. While a tank-specific filter can improve water quality, standard cartridge filtration should not be relied upon to make microbiologically unsafe water safe to drink. If bacteria or other microorganisms are a concern, additional treatment such as ultraviolet disinfection may be recommended.

Pure Water Systems offers dedicated filtration solutions for both town water and rainwater tank supplies, helping you choose the right cartridge for your water source and household needs.

Unless the product instructions explicitly permit it, use cold water only. Hot water may damage filtration media, seals or fittings and can compromise performance.

A whole-house or point-of-entry system treats water as it enters the property, so multiple outlets receive treated water. Its effectiveness depends on the selected stages, water supply and flow requirements.

Whole-house filtration can address issues such as sediment, chlorine-related taste or odour and certain other concerns at multiple taps, including bathroom outlets. The actual benefits depend on the system and cartridges selected.

Town water is usually disinfected by the supplier, while rainwater tanks have different risks, including sediment and microbial contamination. Pure Water Systems offers different configurations for these sources; they should not be interchanged without assessment.

Yes, some whole house water filtration systems can reduce both chlorine and chloramine, depending on the type of filter cartridge used.

Chlorine and chloramine are disinfectants commonly used by Australian water authorities to treat drinking water. While they help control microorganisms in the water supply, some households prefer to reduce these chemicals before the water reaches their taps, showers and baths.

Whole house filtration systems fitted with suitable activated carbon cartridges can effectively reduce chlorine, helping improve the taste and smell of water throughout your home.

Chloramine is more difficult to remove than chlorine and may require specialised filtration media, such as catalytic carbon, or longer contact time with the filter media. Not all carbon cartridges are designed to reduce chloramine, so choosing the right cartridge is important.

Pure Water Systems offers whole house filtration solutions with different cartridge options to suit your water supply and filtration needs. If reducing both chlorine and chloramine is a priority, our team can help you select a suitable cartridge combination based on its filtration capabilities.

The key is choosing a whole house water filter with cartridges specifically designed and tested to reduce the contaminants you're concerned about.

Yes, some whole house water filtration systems can reduce PFAS, but fluoride reduction requires a separate point-of-use drinking water filtration system.

Pure Water Systems' Whole House Triple Filtration System goes beyond basic sediment and chlorine filtration. With our advanced HTO+ filtration technology, it can reduce selected PFAS chemicals, heavy metals, chlorine and other unwanted contaminants, helping improve water quality throughout your home.

Unlike a standard drinking water filter that treats water at a single tap, a whole house filtration system treats water as it enters your property. This means filtered water is supplied to your kitchen, bathrooms, showers, laundry and other household taps.

What about fluoride?

Fluoride requires a different approach. Pure Water Systems offers dedicated fluoride reduction cartridges and reverse osmosis systems designed to treat drinking water at the point of use, usually at your kitchen tap.

Our Fluoride Defence cartridge can be paired with HTO+ filtration in a compatible twin drinking water filter or portable benchtop system, providing targeted fluoride reduction alongside advanced filtration for other contaminants.

For households seeking the most comprehensive drinking water purification, a reverse osmosis system is generally the preferred option, reducing fluoride alongside a broader range of dissolved contaminants.

For the best of both worlds, you can combine a Pure Water Systems Whole House Triple Filtration System with a dedicated fluoride reduction or reverse osmosis drinking water system. This provides advanced filtration throughout your home, with additional purification for the water you drink and cook with.

Explore our HTO & HTO+ Performance Centre at https://purewatersystems.com.au/pages/contaminants-removal to learn more about the contaminants our filtration technology has been tested to reduce.

The right combination depends on your water supply, household needs and the contaminants you want to target.

Yes! At Pure Water Systems, we recommend pairing whole house water filtration with a dedicated drinking water filtration system for the most comprehensive approach to protecting your household's water quality.

While whole house filtration treats water as it enters your property, your drinking water still has to travel through the internal plumbing before reaching your kitchen tap.

A whole house filtration system is known as point-of-entry filtration. It reduces contaminants such as chlorine, sediment and other substances targeted by the selected cartridges before water is distributed throughout your home. This provides filtered water for showering, bathing, laundry, cleaning and everyday household use.

However, once chlorine has been reduced, the water no longer has the same level of disinfectant protection as it travels through your home's plumbing. Depending on the condition of your pipes, water temperature and how frequently taps are used, bacteria can potentially grow in plumbing biofilms or enter through contamination within the system.

Your home's internal plumbing, fittings and fixtures can also introduce additional substances into the water after it has passed through your whole house filter.

This is why we recommend a second stage of filtration where it matters most: your drinking water tap.

A dedicated under-sink drinking water filter or reverse osmosis system is known as point-of-use filtration. It treats water closer to where you drink it, helping reduce specific contaminants that may remain in the water or be introduced as it travels through your home's plumbing.

For households wanting the highest level of drinking water purification, reverse osmosis offers additional protection by reducing a broad range of dissolved contaminants. Where microbiological safety is a concern, a treatment system specifically validated for microorganism reduction or inactivation may also be necessary.

By combining point-of-entry and point-of-use filtration, you get the benefits of filtered water throughout your entire home, plus an additional, targeted filtration stage for drinking and cooking.

Pure Water Systems offers whole house and drinking water filtration combinations designed to work together, so you don't have to choose between protecting your home's water supply and improving the quality of the water your family drinks every day.

UV disinfection may be appropriate where microbiological risks need addressing, provided the water is adequately prefiltered and the UV unit is correctly sized and maintained. UV does not remove dissolved chemicals or sediment.

Any treatment system introduces some pressure loss. Correct sizing for peak household flow, plumbing layout and timely cartridge changes help minimise the impact. Ask Pure Water Systems to assess your property’s requirements based on size and use.

Pure Water Systems has offered Protect & Pure, Protect & Soft and Ultimate Home bundles combining whole-house filtration with drinking-water Reverse Osmosis and/or softening. Bundle inclusions, pricing and compatibility can change, so check the current listing or request a consultation.

Yes, a permanently connected whole-house system should be installed by an appropriately licensed plumber and in accordance with relevant local requirements. Confirm whether installation is included in the quoted price.

Filtering your shower water can make a noticeable difference to your everyday showering experience, particularly if you're concerned about chlorine, dry skin, dull hair or the quality of the water coming into contact with your body.

Australian town water is commonly treated with chlorine or chloramine to help keep it safe as it travels through the water supply network. While these disinfectants serve an important purpose, some people prefer to reduce them before showering and bathing.

A quality shower filter with suitable filtration media can help reduce chlorine and other substances targeted by the cartridge, offering several potential benefits.

For your skin, reducing chlorine exposure may help minimise the tight, dry feeling some people experience after showering, particularly those with sensitive skin.

For your hair, filtered shower water may help reduce dryness and leave hair feeling softer and more manageable. Some people also notice an improvement in how their hair looks and feels after switching to filtered water.

For your bathroom, water quality matters too. Hard water contains dissolved minerals such as calcium and magnesium, which can contribute to white marks on shower screens, mineral deposits around tapware and stubborn soap scum. While standard shower filters don't necessarily remove these minerals, combining filtration with suitable water-softening treatment can help reduce these problems.

Pure Water Systems offers shower filtration solutions designed to improve the quality of the water you shower in every day. For households wanting to address chlorine, sediment and other water quality concerns throughout the home, a whole house filtration system may provide an even more comprehensive solution.

Yes! Shower filters fitted with suitable filtration media are designed to reduce chlorine in your shower water, helping provide a more pleasant showering experience.

Chlorine is commonly added to Australian town water supplies to help control harmful microorganisms. However, some people find that chlorinated water has a noticeable smell or leaves their skin and hair feeling dry after showering.

By reducing chlorine before the water reaches your shower head, a suitable shower filter can help minimise that distinctive chlorine smell and may improve how your skin and hair feel after washing.

Reducing chlorine exposure can be particularly appealing for households with sensitive skin, dry hair or a preference for filtered water throughout their daily routines.

The effectiveness of chlorine reduction depends on the filtration technology, water temperature, flow rate and condition of the cartridge. Replacing your shower filter cartridge at the recommended intervals is important for maintaining performance.

If you'd like to reduce chlorine not just in your shower but also in your baths, bathroom taps and other household water outlets, Pure Water Systems' whole house filtration systems provide another option worth considering.

Chloramine is harder to treat than free chlorine in many short-contact filters. Do not assume a shower filter reduces chloramine unless the specific product has suitable supporting data.

Yes, filtering your shower water may help improve skin comfort and the way your hair feels, particularly if chlorine in your water contributes to dryness or irritation.

Every time you shower, your skin and hair come into direct contact with the water flowing from your shower head. Depending on your local water supply, that water may contain chlorine, dissolved minerals and other substances that can affect your showering experience.

For people who experience dry or sensitive skin, reducing chlorine exposure may help minimise feelings of tightness or dryness after showering. Although a shower filter is not a medical treatment for eczema, some people with sensitive skin prefer showering in water with reduced chlorine.

Your hair may also benefit. Chlorinated water can contribute to dryness for some hair types, particularly colour-treated, chemically processed or already damaged hair. Reducing chlorine may help hair feel softer, smoother and easier to manage.

Hard water is another factor worth considering. High levels of calcium and magnesium can contribute to mineral deposits on hair, leaving it feeling coated or difficult to manage. These same minerals can cause cloudy shower screens, white residue around tapware and soap scum in bathrooms.

It's important to understand that a standard shower filter designed to reduce chlorine does not necessarily soften hard water. If mineral build-up is a concern, a dedicated water softener may be needed to address the calcium and magnesium responsible.

Pure Water Systems offers shower filtration and whole house water treatment options to help improve water quality, whether your priority is reducing chlorine exposure, improving your showering experience or managing hard water throughout your home.

Individual skin and hair results vary, but choosing filtration suited to your water supply is a practical step towards a more comfortable everyday shower.

A shower filter treats water at one bathroom outlet. A whole-house system treats water entering the property and can supply multiple outlets, subject to system capacity.

Some inline shower filters can be fitted to compatible shower connections without modifying fixed plumbing. Follow the instructions and use a licensed plumber if changes to regulated plumbing are needed.

Compatibility depends on the shower connection and available space. Check the thread size and whether you have a fixed, handheld or specialty shower before buying.

A clean, correctly sized shower filter should be selected for the shower’s flow requirements, but some restriction is possible. A blocked cartridge can cause a noticeable reduction.

Yes, with a product intended for bath filling or by treating the home’s incoming water. A standard shower filter is not necessarily suitable for every bath tap or high-flow application.

Follow the replacement interval for the exact product. High usage, sediment and changes in flow can require earlier replacement.

Hard water contains relatively high concentrations of dissolved calcium and magnesium. It can contribute to scale on tapware, shower screens, hot-water equipment and other surfaces.

Common clues include scale deposits, soap that lathers poorly and spots on glassware. A water hardness test is the best way to confirm the level and size a treatment system.

Water hardness varies considerably between regions and water sources in Australia. Local water supplier data or a direct hardness test is more useful than assuming an entire state has the same water.

Many household softeners use ion-exchange resin to replace hardness ions such as calcium and magnesium with other ions during treatment. The resin is periodically regenerated according to the unit’s design.

A water softener and a water filtration system serve different purposes, but they can work together to improve water quality throughout your home.

A water softener is specifically designed to treat hard water, which contains high levels of dissolved minerals such as calcium and magnesium. These minerals are responsible for limescale build-up on shower screens, tapware, tiles and inside household appliances.

Most traditional water softeners use a process called ion exchange. As water passes through a tank containing specialised resin beads, calcium and magnesium are exchanged for sodium ions, reducing the hardness of the water. The system uses salt stored in a separate brine tank to periodically regenerate the resin so it can continue softening water.

The benefits of softened water can include less limescale on shower screens and bathroom fixtures, reduced mineral build-up in hot water systems and appliances, improved soap and shampoo lather, and hair and skin that may feel softer after showering. Softened water can also make bathroom cleaning easier by reducing stubborn mineral deposits.

A water filtration system, on the other hand, is designed to reduce contaminants such as sediment, chlorine, unpleasant tastes and odours, and other substances targeted by the selected filter cartridges.

While a water softener addresses hardness minerals, it doesn't replace a filtration system designed to reduce chemicals and other unwanted contaminants.

For households dealing with both hard water and water quality concerns, combining a Pure Water Systems Whole House Filtration System with a water softener offers a more complete solution. The filtration system treats selected contaminants as water enters your home, while the softener reduces the minerals responsible for limescale and hard water problems.

Together, they can help provide cleaner, softer water throughout your home while protecting plumbing, tapware and household appliances.

A correctly sized and maintained softener can significantly reduce hardness-related scale formation. Existing scale may remain and require cleaning; outcomes depend on the incoming hardness and installation.

The main difference between semi-automatic and automatic water softeners is how they operate, their power requirements and the size of the household they're best suited for.

A semi-automatic water softener is a practical option for smaller to medium-sized households. It uses salt to regenerate the softening resin, with the regeneration process requiring some manual involvement. One of its biggest advantages is that it doesn't require an electrical power outlet, making installation more flexible.

An automatic water softener is generally better suited to larger households or properties with higher water consumption. It uses an electronic control system to manage regeneration cycles automatically, reducing the need for manual intervention. Automatic models require access to a power outlet and are designed to provide convenient, ongoing water softening for homes with greater water demands.

Both systems work to reduce calcium and magnesium, the minerals responsible for hard water, limescale build-up and stubborn white marks on shower screens, tapware and bathroom fixtures.

The best choice depends on your household size, water usage, available installation space and access to electricity.

Pure Water Systems offers water softening solutions for different household requirements, helping you enjoy softer water, less limescale and easier cleaning throughout your home.

Most salt-regenerated ion-exchange softeners require suitable regeneration salt. Consumption depends on hardness, water use, capacity and regeneration settings.

Compatibility depends on the actual hardness, water chemistry and the selected product. Pure Water Systems’s current product-finder rules direct standard softener recommendations to town-water applications; tank-water cases need individual assessment.

Sizing should consider measured hardness, household water consumption, peak flow and regeneration frequency. Pure Water Systems can help assess these details before a purchase.

Water quality and taste can vary between caravan parks, campgrounds and stored water supplies. A suitable filter can address specific issues such as sediment or chlorine taste when used with an appropriate source.

It depends on whether you need inline hose filtration, a portable drinking-water filter or treatment for a stored tank. Consider source-water quality, flow, storage space and tested contaminant claims.

An inline filter is fitted into a suitable water hose or supply line to treat water as it flows through. Check flow direction, fitting compatibility and intended use.

Yes, if the filter is compatible with the supply and intended contaminants. Check local drinking-water notices, because a basic taste-and-odour filter is not a substitute for required disinfection.

Some systems can treat stored tank water, but tank hygiene and microbiological safety must also be managed. Clean and maintain the tank and use treatment appropriate to the water source.

Many caravan filters are designed to reduce sediment and/or chlorine taste, but the result depends on the cartridge. Check the exact Adventure Series or other product specification.

Creek, river and other untreated water sources can contain harmful bacteria, viruses, parasites, sediment and chemical contaminants, so it's important to use the right water purification system before drinking this water.

Standard caravan and camping water filters are generally designed to improve the taste and quality of water from established supplies, such as caravan park taps or stored tank water. They should not be relied upon to make untreated creek or river water safe to drink.

For travellers wanting more comprehensive water purification, a portable reverse osmosis system is worth considering. Reverse osmosis uses an extremely fine membrane to reduce a broad range of contaminants, including many dissolved chemicals, heavy metals and microorganisms.

However, untreated surface water presents additional risks. Even a portable reverse osmosis system should not be assumed to make creek or river water safe without appropriate sediment prefiltration, validated microbiological treatment and suitable maintenance. Some contaminants may also require additional treatment.

If you regularly travel off-grid or rely on natural water sources, Pure Water Systems can help you explore portable reverse osmosis options and determine what additional treatment may be required for your intended water supply.

For drinking and cooking, the safest option is to use a known potable water source unless your complete treatment system has been specifically validated for the untreated water you're collecting.

Follow the product instructions for the correct flow direction, hose connections, flushing and pressure limits. Check for leaks before drinking the treated water.

Every filter introduces some resistance, especially as sediment accumulates. Choose a cartridge suited to the required flow and replace it as instructed.

Follow the manufacturer’s guidance for draining, drying or sanitising the unit. Do not leave used wet cartridges sitting for long periods without appropriate care.

Replacement frequency depends on the cartridge, incoming water and volume treated. Follow the stated service interval for your exact Pure Water Systems product rather than using one schedule for every filter.

Check the model name, cartridge label or previous order details. If you are unsure, send Pure Water Systems a photo of the system and cartridge so compatibility can be confirmed.

We do not recommend using replacement filter cartridges from other brands in Pure Water Systems filtration systems.

Our replacement cartridges are specifically selected to work with our filtration systems, ensuring the correct fit, reliable operation and intended filtration performance.

Although some cartridges from other manufacturers may appear similar in size or design, differences in materials, seals, construction and filtration technology can affect how well your system performs. An incompatible cartridge may cause leaks, reduce water flow or fail to provide the contaminant reduction you expect.

Using genuine Pure Water Systems replacement cartridges also gives you confidence that you're maintaining your system with the filtration technology recommended for your water supply and household needs.

For the best performance, reliability and longevity, we recommend using genuine Pure Water Systems replacement cartridges designed for your particular system.

If you're unsure which replacement cartridge you need, our team can help you identify the correct option so you can continue enjoying high-quality filtered water.

Use the procedure supplied for your model, including isolating the water supply where required, removing the old cartridge, installing the replacement and checking for leaks. Do not assume every Quick Change head uses the same release mechanism.

Follow the system instructions, isolate water and release pressure before opening housings. Check O-rings, cartridge orientation and leaks, and use a licensed professional if required.

The membrane has a different service life from the prefilters and postfilter. Follow the Reverse Osmosis model’s maintenance instructions and investigate any changes in treated-water quality or production rate.

A loaded cartridge, supply-pressure change, valve issue or other restriction can reduce flow. Check the maintenance schedule and troubleshoot according to the system instructions.

Discolouration can result from captured sediment, iron or other particles, while some new carbon cartridges release fine carbon dust during initial flushing. If the change is unexpected, check the instructions and contact Pure Water Systems.

Turn off the water supply to the system if safe to do so, protect nearby electrical equipment and inspect visible connections without dismantling pressurised components. Contact Pure Water Systems or a licensed plumber for help.

Leak Ninja is a Pure Water Systems leak-protection product intended to provide an additional safeguard around water filtration installations. Check the exact model instructions for how it detects or responds to leaks and its installation requirements.

Australian reticulated drinking water is regulated and routinely monitored against applicable health-based requirements. Local conditions, plumbing and individual preferences can still influence whether someone chooses additional filtration.

Potential concerns vary by source and can include sediment, disinfection by-products, metals, agricultural chemicals and some emerging contaminants. A local water quality report or targeted test is more informative than a generic list.

PFAS are a large group of persistent manufactured chemicals used in many industrial and consumer applications. Some have been detected in water sources, and health-based guidance and treatment recommendations continue to evolve.

Certain activated-carbon, ion-exchange and reverse-osmosis technologies can reduce selected PFAS. Effectiveness varies by compound and system, so use product-specific independent test results to support claims.

No. Boiling water does not remove PFAS, fluoride or heavy metals. In fact, prolonged boiling can actually increase the concentration of some contaminants in the water left behind.

When water boils, some of it evaporates as steam, but dissolved substances such as fluoride, lead and many PFAS chemicals remain in the water.

For example, if you boil one litre of water containing fluoride until only half a litre remains, the fluoride concentration could approximately double. This doesn't mean boiling creates more fluoride. It simply means the same amount is now contained in less water.

Normal boiling in a kettle usually causes only a small amount of evaporation, so the increase in fluoride concentration is generally minimal. However, boiling is not an effective method of fluoride removal.

The same principle applies to many heavy metals and PFAS chemicals. Boiling can kill many harmful microorganisms, but it does not reliably remove dissolved chemical contaminants.

If you want to reduce these substances in your drinking water, you need a filtration system specifically designed for that purpose.

Pure Water Systems offers dedicated Fluoride Defence cartridges that can be paired with our advanced HTO+ filtration technology to target fluoride alongside selected PFAS chemicals, heavy metals and other unwanted contaminants.

For households wanting more comprehensive drinking water purification, our reverse osmosis systems use specialised membrane technology to reduce fluoride, PFAS, heavy metals, dissolved salts and a broader range of contaminants.

Chlorine and chloramine are disinfectants used by water suppliers. Chloramine generally persists longer in distribution systems and can require different filtration media or longer contact time to reduce.

Chlorine helps control microorganisms during water treatment and distribution. The fact that water is disinfected does not mean customers cannot prefer filtration for taste or other specific reasons.

Some filtration technologies can capture particles within their validated size range. Microplastic sizes and test methods vary, so avoid broad removal percentages unless supported for the exact product.

Metals can originate from source water, treatment processes or plumbing materials and fittings. The metal, concentration and source determine whether testing or targeted filtration is appropriate.

Town water is treated and monitored by a supplier, while privately collected rainwater depends on roof, gutter, tank and maintenance conditions. Tank owners may need extra sediment control, disinfection and periodic testing.

Manufacturing and assembly locations can differ by component and product line. Pure Water Systems should publish verified, product-specific origin and assembly information rather than implying every component is made in Australia.

Testing and certification vary by product and claim. Look for the specific test standard, laboratory report and model covered. WaterMark plumbing certification, where applicable, is not the same as independent contaminant-reduction testing.

Warranty terms depend on the product. Previous Pure Water Systems bundle information listed two years for some whole-house components and 12 months for certain Reverse Osmosis and softener components; check the current product terms and Australian Consumer Law rights before publication.

Some Pure Water Systems systems require professional plumbing installation. Contact the team to confirm available installation support, service areas and whether installation is included in the purchase price.

Check delivery eligibility, charges and estimated timeframes at checkout or with the Pure Water Systems team. Oversized systems and remote destinations may have different arrangements.

Pure Water Systems stocks replacement cartridges for a range of systems. Supply the model or a clear photo of the cartridge and housing so the team can check availability and compatibility.

Pure Water Systems has promoted Zip Money interest-free finance for eligible whole-house purchases, including 12- and 24-month options on qualifying orders. Current eligibility, fees, terms and promotional conditions must be checked before publishing.
