We offer some of Australia’s most trusted under sink water filters with options that let you enjoy ready-to-drink water from the tap whenever you need it.

Water filtration systems remove physical impurities, such as sediment debris and larger particles, from the water. Our filters improve the clarity, taste and odour of the water before it comes out of your tap. We use premium and exclusive filters, such as our Hi-Tech Optimiser Cartridge (HTO). The HTO uses an electrostatic outer wrap, advanced carbon block technology and a pharmaceutical grade membrane to remove unpleasant water taste, odour and up to 101 contaminants, depending on water quality and cartridge model.

Beyond removing larger contaminants, the best under sink water filter is one that can also eliminate worrisome fluoride, viruses, chemicals and other microscopic contaminants. We use technologies such as reverse osmosis to ensure the highest level of purification, so you can thoroughly enjoy water for drinking, cooking, cleaning and many other uses.

Removing impurities for pure refreshment

Each under sink water filter system is carefully engineered to target harmful and unwanted contaminants. Unfiltered water can contain bacteria and parasites that may cause gut health concerns, heavy metals linked to long-term health issues, and chlorine or fluoride that impact taste and odour.
