Description – Big Blue Whole House Filters WF10

Whole house filters remove chlorine and other chemical tastes, odours plus dirt, sediments, making water cleaner, clearer, and safer for your whole house. In addition, they also protect your appliances, fixtures and pipelines.

Mounting Bracket Included.


Our whole house water filters are usually placed in the main water line entering the home and generally have capacities to filter 10,000 – 100,000 gallons of water before you have to change the cartridge.

We offer whole house water filter housings and filter cartridges that you can mix and match yourself. You can even connect 2 housings in series to form a unique system designed for your situation. For example, first stage is sediment filtration, then followed by a carbon or iron removal filter in the second housing as a second stage filtration (WF-20).
