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.

Only lasted less than 4 months before I had to replace. And that's in an apartment with 1 bathroom. The price is great but I guess you get what you pay for.

Easy to install, quality build seems good, water pressure seems unaffected; I'll update my review if the filter efficiency drops before it's supposed to. Overall, nice alternative to the Aquapure filter.

I purchased this item because it was a replacement for the OEM filter that is now outrageously priced. It was about $100 cheaper that the OEM unit I bought last August (2024.) Seems to be working properly. If I have no problems I will definitely buy again next August.
