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 cartridge features an activate carbon block filter effective with either chlorinated (municipal) and non-chlorinated (well water) systems.

The AP904 includes a Aqua-Pure AP917HD-S replacement filter along with the head and mounting bracket.

NOTE: No warranty is given as to the estimated service life of the filter cartridge as it may vary with local water conditions and water consumption.

Recommended Pre-Filter Systems

For water sources with high levels of sediment, dirt, and rust, we strongly recommend using a sediment pre-filter system to allow the AP904 to utilize its full filtration capacity on the reduction of scale and chlorine rather than on sediment collection.

Option 2: Aqua-Pure AP802B system along with an Aqua-Pure AP810-2 filter
