A whole house water filter is a filtration system installed at the point where water enters your property, so it treats the water before it reaches your taps, showers, toilets, laundry, hot water system and appliances. Unlike a single-point filter, a whole house water filter system provides filtered water across the entire home. That means better water quality not just for drinking, but also for showering, washing, cooking and protecting the plumbing and appliances that rely on your water every day.

For many homeowners, yes. A whole house water filter can help improve water quality throughout the home by reducing chlorine, chloramine, sediment and other unwanted contaminants before they circulate through your plumbing. It can also help minimise limescale buildup caused by hard-water minerals, which may reduce wear on taps, showerheads, hot water systems, dishwashers and washing machines. For homeowners in Perth, where water is often chlorine-treated and mineral-heavy, a whole house filter can also improve shower comfort, reduce chemical smell, and deliver cleaner water from every outlet.

The main difference is the point of filtration. An under-sink water filter only treats water at one outlet, usually the kitchen tap. A whole house filter or whole house water filter system is installed at the mains, so it treats the water entering the entire property. That means every tap, shower, bath, toilet, laundry connection and appliance receives filtered water. If you want protection for the whole home rather than one drinking tap, a whole house water filter is the better fit.

A poorly designed system can affect pressure, but a properly selected whole house water filter system should maintain strong flow across the home. Pure₂O systems are built for high-flow residential use, which means they are designed to filter water effectively without causing the frustrating pressure drop that can happen with lower-grade or undersized systems. This is especially important in family homes where multiple taps, showers or appliances may be running at once.

Depending on the filtration setup you choose, Pure₂O whole house water filters are designed to reduce a range of common contaminants and water issues found in Perth homes. These may include sediment, dirt, rust, chlorine, chloramine, PFAS, microplastics, heavy metals, volatile organic compounds (VOCs), chemical taste and odour, and scale-forming impurities. Our Premium Setup includes more advanced filtration media for homeowners wanting enhanced reduction of PFAS, chloramine and ultra-fine contaminants, while both setups are designed to improve water quality throughout the entire home.

Replacement timing depends on your water quality, the type of filtration system installed, and how much water your household uses. Homes with higher sediment load or heavier daily water use may need more frequent replacement than homes with lower demand. In most cases, replacement filters are changed on a scheduled basis to help maintain water quality, flow rate and system performance. Pure₂O supplies replacement filter packs matched to your system, making ongoing maintenance straightforward and helping ensure your whole house water filter system continues performing properly over time.

Yes. Pure₂O systems are selected specifically for Perth water conditions. That includes chlorine and chloramine-treated supply, mineral-heavy water that can contribute to limescale buildup, sediment, and in many areas, coastal exposure that can be harsh on lower-grade external systems. Our systems use a premium-grade housing, high-flow design and filtration media tailored to local water conditions, making them well suited to residential homes across Perth’s northern suburbs.

No. Pure₂O focuses exclusively on whole house water filters and whole house water filter systems for residential properties. Our systems are designed to filter water at the source so the entire home benefits, rather than just one outlet. This allows homeowners to improve water quality across showers, taps, laundry, appliances and plumbing, not just the kitchen sink.

All Pure₂O systems are installed by licensed plumbers. This ensures your whole house water filter is fitted safely, correctly and in the best location for long-term performance. Professional installation also helps ensure the system is properly integrated with your home’s plumbing, maintains strong flow, and is set up for easier servicing and filter replacement in the future.

Yes. Pure₂O supplies replacement filters and replacement filter packs matched to your installed system. This makes it easier to maintain your whole house water filter system with the correct filtration media, rather than guessing which cartridges are compatible. Ongoing filter replacement is an important part of maintaining water quality, flow and long-term system performance.
