Review on 3M Aqua-Pure AP917HD-S Replacement Water Filter: Enhanced Sanitary Quick 💧 Change for AP904 System, Reduces Sediment, Chlorine Taste, Odor, and Scale by Christy Brewer

I love these filters. This is the fourth time I've been using them, I think they last about six months. I use my water softener for gallon counting and so far this filter has really helped reduce scale and build up in my showerheads and sinks. I can say it does its job because when the water pressure drops and I replace it the pressure seems to go back up meaning it is doing its job picking up contaminants from the water. I connected it before the water softener and so far it works perfectly. It's a bit more expensive, but it gets rid of the chlorine smell, which I'm very happy with.
