The Tier1 RFC-93 filter cartridge is a great option for your point-of-entry system. It's standard 10 x 2.5 inch size fits in most 10 inch housings and other high flow rate applications. The RFC-93 filters down to 25 nominal microns in size, which will help eliminate Chlorine taste and odor. The filter's design incorporates a polyethylene shell and a polypropylene core, as well as radial flow that reduces the amount of carbon fines getting into your water.
