Looking For Replacement Filters?
We recommend the following Aqua-Pure scale prevention filter option - AP917HD-S.
The Aqua-Pure AP904 reduces chlorine taste and odor, particulates, and scale. Perfect for hardness removal, the AP904 is fitted with a scale inhibition media that does not allow for built-up of hardness in water-using appliances.

The AP904 is ideal for both residential and light commercial applications and features 3M's sanitary quick-change filter replacement technology. The filter cartridge is effective with both chlorinated (municipal) and non-chlorinated (well water) systems.

The AP904 includes a Aqua-Pure AP917HD-S replacement filter.
