Whole House Water Filters: What To Know Before Buying

AquaCo whole house water filter system for an Australian home

Most people searching for a whole house water filter are not looking for a small bench-top jug. They are trying to work out whether one system can improve the water before it reaches the kitchen, bathrooms, laundry and appliances.

A whole-house system filters water at the point it enters the home, before it branches to individual taps.

Start with your water source

Mains water, rainwater tanks and bore water can all need different treatment. Mains water buyers often care about chlorine taste, odour, sediment and PFAS. Tank and bore water may need testing first because the right setup depends on the actual water quality.

Match the filter to the concern

For taste and smell, look at the carbon stage. For grit, rust and fine particles, look at sediment filtration. For PFAS, do not rely on vague claims. Look for specific PFAS reduction data and named compounds such as PFOA and PFOS.

Check flow rate and capacity

A whole-house system has to keep up with showers, taps and appliances. The AquaCo Premium PFAS system is rated to 300,000 litres and up to 60 LPM, which is why those specs should sit close to the product card and PDP decision area.

Plan the install before you buy

Whole-house water filters usually connect near the mains water inlet, before the water line branches around the home. That is licensed-plumber territory. Before buying, check the available space, pipe access, pressure requirements and whether the system needs clearance for future cartridge changes.

Where this fits in the Home Harvest Hub range
