Product review (5 stars): Great Drinking Water!
Upgraded my old Aquacrest filter (53&42 only) to this higher filtration model. Easy to replace and activate. The only thing I'm not a fan of is the reminder tab included. The other models have a sticker for the future replacement month I've just been overlaying. This one had a fancy button that apparently slowly releases dye until the six month mark is hit. Pretty unnecessary I think. But otherwise, very happy with these filters.
