Review on Pentek R30 Pleated Polyester Cartridge: Superior Filtration Performance for Crystal Clear Water by Lissette Molina

We have well water and we used American Plumber 30 filters first which lasted about 3.5 months before any changes were needed. Pentek prices were too good not to try. This is the last 2.5 months that we need a replacement. Given the huge difference in price, I don't mind changing it a little more often. I didn't notice any difference in water quality/taste between them and AP 30.
