Because this is a 5-micron carbon block filter, it will provide longer life than Everpure 1/2 micron precoat water filters. With 5-micron filters you are giving up NSF standard 53 for cyst reduction, for longer filter life.
Examples of cysts are Cryptosporidium and Giardia Lamblia. You will still get exceptional chlorine and particulate reduction as well as scale control.
For more capacity, upgrade to the 4CB5K water filter, which is approx. twice the length and has twice the capacity.
