Puretec PP Series Pleated Polyester Washable Cartridge

The Puretec PP series is a pleated polyester sediment cartridge. The pleats pack more surface area into the same housing, so it holds more dirt and runs longer between changes, and it is washable, so on dirty water you can rinse it and put it back rather than replacing it. Resistant to bacteria and chemical attack.

Which micron? 20 or 50 micron for a coarse first stage. 5 micron is the everyday choice. 1 micron polishes and is rated for cyst reduction, which is what you want ahead of UV or where the supply is roof or surface water.

Basic or Premium? The PP is the Basic pleated cartridge. The Premium equivalent is the PL, which uses heavier duty polyester with a higher pleat count, so more capacity and a longer run between washes. On genuinely dirty water the PL is worth the difference. On town supply the PP is plenty.

Which size? Slimline is the standard 2.5 inch diameter. Large Diameter is 4.5 inch and takes far more flow and far more dirt before it blocks, which is why whole house systems use it. The 10 inch or 20 inch is the length. Your housing decides this, so measure the old cartridge or read the housing label before ordering. Note that Puretec's Basic large diameter cartridges are coded LD, and the Premium ones MP. They fit the same housings.
