Review on Pentek ECP5 BB Cellulose Polyester Cartridge by Dwayne Pore

I have a large blue filter that lets water into the house to filter out particles and these Pentek filters fit into this housing. The 5 micron filter has no noticeable difference in flow rate. I think the 1 micron filter has a very small pressure drop, so small that I wasn't sure if that was true or if it was just a placebo effect. . . because I expected it to be there. I think it's a slight drop in flow rate. When it comes time to get my irrigation system up and running I will see if I notice a difference between the different emitters and drippers.
