Filter used by our Well & Pump Company Review by Wish I could sa
I use this filter at my parents' home built in 1950 which has its own well; however these days a lot of natural minerals cause odor and sediment build up. Our Well and Pump Company was providing these filters to us but I decided to see if I could find them cheaper on line. I'm thrilled to have found (Posted on 6/4/13)
good choice Review by john
For about half the price, I replaced my old FXSVC under sink water filter set with a Pentek CBR2-10 and a Pentek C1 filter cartridges. They fit perfectly into my GE filter system and the water still tastes great after two months of use. I purchased two sets of cartridges in the same order and received free shipping.

Half the cost. Review by Scott
Service was excellent and I did not know how much my water softener company was gouging me for the filters until I ordered them from you. Thanks! (Posted on 4/12/15)
