Whole House Filters For Mains Water Homes

Unlike point-of-use units that filter water at just one tap, a whole house water filter delivers filtered water to every tap in the home.

A home water filtration system can improve everyday water quality throughout the house. It helps reduce sediment, chlorine and other common contaminants, which can improve taste and odour while also helping protect taps, shower screens, appliances and pipework from buildup over time. It also means you can enjoy filtered water from any tap in the home.

Chlorine is commonly used to disinfect mains water, but many households notice its taste and smell. Reducing chlorine can make water more pleasant to drink and use around the home. Reducing chlorine in shower and bath water can also help with dry skin, dandruff and irritation. It can also help hair to feel softer and retain colour and shine for longer.

The main difference is where the water is filtered and how much of the home is covered. A whole house system filters water as it enters the property, so multiple outlets benefit from filtered water. An undersink system filters water at a single point, usually the kitchen sink, and is typically chosen for drinking and food preparation only.

The right size depends on your home's water demand and flow rate. Key factors include the number of bathrooms, number of people living in the home, how often multiple taps or showers are used at once, and the local water quality. Puretec offer 10 inch and 20 inch systems to suit different household flow requirements. Choosing the correct size helps maintain strong performance without restricting water pressure.

You don't need a cover; however, using one helps protect the filtration system from weather, sunlight, and everyday outdoor wear. The WH Series is suitable for outdoor installation. However, the system will last longer if protected from direct sunlight.

Cartridge life can vary depending on water usage, incoming water quality and the type of cartridge installed. Homes with higher sediment levels or greater daily water demand may require more frequent cartridge changes. Regular and timely replacements (every 6-12 months) help keep the system performing at its best.

A triple stage system uses three cartridges, allowing water to pass through more than one level of filtration before reaching the home. This gives greater flexibility to target different water concerns, such as sediment, chlorine and scale reduction, depending on the model selected. A dual stage system uses two cartridges, which may suit more straightforward filtration needs. For households wanting broader protection and more tailored performance, a triple stage setup offers added capability.

The best system depends less on floor size and more on water usage. Smaller homes or homes with lower flow demand may be well suited to the more compact models. Larger homes or properties with multiple bathrooms generally benefit from larger-capacity systems designed for higher flow rates. The best fit comes down to balancing household demand, water quality and the features you want, such as chlorine reduction or scale management.

The products featured here are designed for houses on mains or town water. For rainwater applications, the best solution depends on factors such as tank condition, sediment load, pump setup and the quality of the collected water. Browse our range of whole house water filters for rainwater here.

Not always. The best setup depends on how you use water around your property. We recommend discussing your filtration requirements with your plumber before installation. For areas such as garden taps, irrigation lines, or swimming pool supply, installing a bypass can be a practical option. This allows water to flow to selected outdoor uses without passing through the filtration system. This can help preserve cartridge life and avoid filtering water where it may not be necessary.
