Just know that if you have really bad well water, they won’t last 6 months. Mine lasted 2 months and that is with a 40 micron spin down filter on the system prior to these filters! After 2 months, I saw 45 psi of water pressure coming into the first filter, and 10 psi of water pressure coming out of the last filter! Even with the filters clogged up this badly, they still filtered the water really good though!! I 100% recommend these filters to others, and I have done so! Review: Quality, effective - I appreciate these large filters since replacement at my house is just once a year. They seem well constructed and contribute to our great tasting water. ## Features - [Premium & Reliable Material] Made of premium coconut shell activated granular carbon element that is ground up and held together loosely inside a filter cartridge, the SimPure GAC carbon filter effectively adsorpt contaminants from entering the water.
