Whole-house water filtration for cleaner water throughout your home

Concerned about the quality of water entering your home? An entire-house water filtration system could be the solution.

A whole-house filtration system delivers cleaner, filtered water throughout your home, improving the water used for showering, bathing, washing, cooking and everyday household use. Pair it with a dedicated drinking water system for the highest quality water at your kitchen tap.

At Pure Water Systems, we've spent more than 30 years helping Australian homes enjoy cleaner, better-tasting water with our trusted water filtration systems. Our house water filtration systems are built for long-term performance and easy maintenance, and we offer options tailored to both town water and tank water.

Benefits of entire-house water filtration

A whole-house water filter system removes a wide range of contaminants that can enter your water supply, including chlorine, sediment, heavy metals, and other organic matter. Here's what a house water filter system does for your home.

• Reduces chlorine levels and that chlorine smell and taste some Australian homes notice straight from the tap
  

• Filters out sediment, rust and other particles that can build up in old pipes, including copper pipes
  

• Helps protect appliances and water heaters from scale deposits and scale buildup, which can shorten their working life

• Provides cleaner, filtered water throughout your home, while allowing a dedicated point-of-use filtration or reverse osmosis system to deliver premium drinking water at the kitchen tap.
  

• Supports consistent water pressure and flow rate when the system is sized correctly for your household
  

Whole-house filtration systems are known as Point-of-Entry (POE) systems because they filter water where it enters your home. They deliver cleaner, filtered water to every kitchen, bathroom and water-using appliance throughout your home, while providing the ideal foundation for a dedicated Point-of-Use (POU) drinking water system at your kitchen tap.

If hard water is behind your scale buildup, a Pure Water Systems water softener can help too. It reduces the mineral content in your water, which means less wear on your appliances and a noticeable difference in how your laundry, hair and skin feel. A water softener also reduces calcium deposits on taps and shower screens, making cleaning much easier.

What does entire-house water filtration mean for everyday life?

A whole-house filtration system is designed to improve the quality of the water used throughout your home. Installed outside your home and connected to your incoming water supply, it filters the water before it enters your household plumbing, delivering cleaner water to every kitchen, bathroom, and water-using appliance.

Many companies market whole-house filtration as a complete drinking water solution. While the water may be safe to drink, we believe that both a whole-house system and a dedicated drinking water system play important roles.

Australian water authorities add chlorine or chloramine to help keep drinking water safe as it travels through the public water network. A whole-house filtration system, also known as a Point-of-Entry (POE) system, reduces these disinfectants before the water enters your home. The filtered water then travels through your household plumbing before reaching your kitchen tap.

That's why we recommend pairing your POE system with a Point-of-Use (POU) filtration or reverse osmosis system. Installed at your dedicated drinking water tap, it provides a final stage of filtration or purification immediately before the water enters your glass.

It's a simple philosophy: your POE system takes care of the water you use throughout your home, while your POU system takes care of the water you drink. Together, they create a complete home water solution.

Many customers tell us they notice softer hair, cleaner, healthier-looking skin, less chlorine taste and odour around the home, and reduced scale build-up on taps, shower screens and fixtures. Whether you're on town water or tank water, we'll recommend the right filtration combination for your home and water source.

Whole-house systems designed for Australian homes

Whether you're on tank water or town supply, our whole-house water filters are built to handle Australian conditions. We offer compact single-filtration setups for smaller households, through to high-capacity twin and triple-filtration systems for larger homes with higher daily usage and water-quality needs.

From helping you choose the right system to supporting you long after installation, our experienced Australian team is here to help. Depending on your location, we can recommend trusted installers or work with your preferred licensed plumber. We'll also help you choose the right replacement cartridges and provide ongoing support to keep your system performing at its best.

For homes wanting an extra layer of protection at the kitchen tap, we'd still recommend pairing your whole-house filtration system with a point-of-use system, like an under-sink or reverse osmosis system, since some contaminants, like fluoride, can pass through standard filtration and require a reverse osmosis system to remove.

FAQs about entire-house water filtration 

What is entire-house water filtration, and how does it work?

Entire-house water filtration is a comprehensive Point-of-Entry (POE) system connected to your home's incoming water supply. It filters the water before it enters your household plumbing, delivering cleaner water to every kitchen, bathroom, and water-using appliance in your home.

Most systems use several stages of filtration, each targeting different contaminants. A typical setup starts with a sediment filter to remove larger particles, followed by an activated carbon stage to reduce chlorine and organic chemicals, with additional filtration sometimes added for specific concerns such as heavy metals or bacteria. 

Because filtration occurs before the water is distributed throughout your home, every kitchen, bathroom, laundry, and outdoor tap benefits from cleaner, filtered water. For drinking and cooking, we recommend pairing your point-of-entry system with a dedicated point-of-use filtration or reverse osmosis system for a final stage of filtration or purification at the tap.

Why should I install a whole-house filter system?

Many homeowners choose a whole-house system to reduce chlorine, chloramine, sediment and other common contaminants, helping improve the water used for showering, bathing, washing, cooking and protecting household appliances. Many customers also notice less chlorine taste and odour, softer-feeling hair, cleaner, healthier-looking skin, and reduced scale build-up on taps, shower screens and fixtures.

For drinking and cooking, we recommend pairing your whole-house filtration system with a dedicated Point-of-Use filtration or reverse osmosis system. This provides a final stage of filtration or purification immediately before the water reaches your glass, delivering the highest quality drinking water for your family.

If you live in an area with hard water, a water softener may also be recommended. Unlike a filtration system, a water softener doesn't remove contaminants. Instead, it reduces hardness minerals such as calcium and magnesium that naturally occur in the local geology. This helps minimise scale build-up in pipes, hot water systems and appliances while improving the performance of soaps and detergents.

How is a whole-house system different from other home water filtration systems?

Point-of-use systems, like under-sink or bench-top filters, only treat water at one specific tap. A whole-house system is installed at the point where water enters your home, so it treats all water, meaning every faucet, shower, and water-using appliance benefits from filtered water. 

Whole-house systems also tend to use higher-capacity filter cartridges than smaller point-of-use filters, so they generally need changing less often per volume of water they handle. 

Even so, most households get the best result from running a whole-house system alongside a point-of-use filter in the kitchen for that extra layer of protection where it matters most.

What maintenance does a whole-house filtration system need?

Ongoing maintenance is fairly straightforward once your system is set up correctly. Filter cartridges are typically replaced every 12 months, depending on your household usage and water quality. 

It's worth having a quick look over the system every few months to check for leaks or general wear. Some systems, particularly those with a water softener or UV component, benefit from an annual professional check to make sure everything's running at optimal performance. 

At Pure Water Systems, we handle the reminders for you and call when your whole-house filter cartridges are due, so you're never left wondering if it's time for a change.

Can I install a whole-house filter system myself, or do I need professional installation?

Whole-house filtration systems should always be professionally installed by a licensed plumber. Because they're connected directly to your home's incoming water supply, correct installation is essential to ensure reliable performance, maintain water pressure, prevent leaks, and meet warranty requirements and home insurance requirements.

Depending on your location, we can recommend experienced installers, or you're welcome to use your preferred licensed plumber. Our experienced Australian team is also available to answer any questions and provide ongoing product support before, during and after installation.

How do I choose the right size whole-house filter system for my home?

A few things determine the right fit: 

• Flow rate matters most, since the system needs to keep up with your household's water usage without affecting water pressure.
  

• We look at how many bathrooms and water-using appliances run at once in your home.
  

• Household size plays a role, too: larger families or homes with higher daily usage generally need a system with a larger filter capacity. 

We'd also recommend having your water tested if you haven't already, since knowing exactly what's in your water supply, whether that's from a bore, tank or town connection, helps us recommend the right combination of filters for your situation.

How do water softeners work?

If you live in a hard water area, you’ll usually notice the signs around your home. White limescale can build up on taps, kettles and appliances, while shower screens may become cloudy or frosted with mineral deposits that are difficult to remove. Hot water systems and plumbing can also gradually collect scale, affecting performance over time.

Hard water can make soaps, shampoos and detergents less effective. Clothes may feel stiff, look dull, or retain stains and odours after washing, while plates, cutlery, and glassware can come out of the dishwasher with cloudy marks, mineral spots, or detergent residue. Hair and skin may also feel dry after showering.

A water softener reduces naturally occurring hardness minerals, primarily calcium and magnesium, helping soaps and detergents perform more effectively. The result is clearer shower screens, cleaner dishes, brighter laundry, better-performing appliances, less scale build-up and noticeably softer water throughout your home.

Do whole-house filters affect water pressure?

A correctly sized and installed whole-house filter shouldn't cause any noticeable drop in water pressure. Where households notice an issue, it's usually because the filter cartridges are overdue for replacement and have become clogged, or the system was undersized for the home's actual water usage in the first place. 

Keeping on top of filter changes and choosing a system with the right flow rate for your household are the two biggest factors in maintaining consistent water pressure long term.

Are replacement filter cartridges easy to find?

Yes. We stock a full range of replacement cartridges and components for every whole-house filter system we sell, so you're never left searching for compatible parts. We'll also send you a friendly reminder when it's time to replace your cartridges, making it easy to order what you need and keep your system performing at its best. 

If you're ever unsure which cartridge your system takes, our Queensland-based team can look it up for you over the phone.
