### ⭐⭐⭐⭐⭐ Review
*by K***W on 13 July 2025*

Why did you pick this product vs others?: This is a direct brand replacement. I believe it is the best value filter you can get. It replaced our last filter we have been using for a year, way beyond it's volume and expiration period and still removes most of that reservoir water smell from the tap. This replacement along with a Brita filter pitcher for a fringe improvement gives us near snow melt well water quality you get in the high mountains in the spring. Our tap water isn't anywhere near the hard water you get from a southern California tap but has a bit of lake water smell, occasional mold fungus that immediately starts growing on the toilet bowl with a lot of new PVC pipe leaching into it, while on it's way here. Following any fungus blasts some kind of fungicide usually follows. Needless to say, a chemical reducing .5 micron biological safe water filter is a must here. This is the one that has led the pack for us.
