AP917HD-S Water Filter, Compatible with Aqua-Pure® AP917HD-S Whole House Sediment/CTO Filter Cartridge for 3M® Aqua-Pure® AP904 System, W/Scale Inhibitor (1 Pack)

This filter works beautifully with my tankless water heater. It screens out harmful particles and provides clean, clear filtered water throughout the house. We are a family of two, and only need to change the filter once a year. We’ve been using this filter for years with no problems. It’s easy to change out and has caused no problems. It does not affect water pressure.

Seems to work just the same as the 3M filter. No complaints. Snapped into place just like a 3M, water pressure the same and clear as ever.

It leaks and water got everywhere, bad seal don’t waste your money, put it towards something a better

Works well and no leak has been found. Will recommend to others.

Filter when locked into position backs off when pressure was put on filter resulting in small drip coming from filter. Filter did seal off eventually. Added a small 1/8 inch piece of plastic to wedge locking tab to prevent it from backing off and dripping when locked in place.
