Looking For Replacement Filters?
We recommend the following Aqua-Pure filter - AP917HD.
The Aqua-Pure™ AP903 is best for heavy household municipal water use, as it has a capacity of 100,000 gallons and a 5 micron activated carbon filter that ensures you only the purest form of drinking water. It has a high flow rate, easily meeting the needs for most residential and light commercial uses and is effective with both chlorinated (municipal) and non-chlorinated (well water) systems.

The filter's sanitary quick change (SQC) design allows for fast and easy change-outs without having to contact the filter media or the need for a filter wrench.

The system ships with an Aqua-Pure AP917HD replacement filter.
