Review on 🚰 3M Aqua-Pure AP910R Water Filter Cartridge: Sanitary Quick Change Replacement, 1 Per Case - Find Now! by Stetson Olsen

So, I just replaced my first filter (I was waiting for a pressure drop, but I didn't notice anything) and wanted to leave a note for people who find it difficult to release the water pressure (making the locking tab very difficult to move). If the locking tab is difficult to move to the right: 1) turn off all water circulation pumps 2) after the water has left the channel, the pressure in the filter may remain. Open the inlet valve (with the tap open) for one second. 3) At this point, the locking tab should move slightly to the right. In this case, close the inlet valve. 4) Now unlock the filter. It should be as easy as in the video. If the locking tab does not move easily, there is still pressure in the filter. 5) Keep an eye on a little water, but not much. Much luck!
