Pentek is the largest brand in the filtration industry. With over 50 types of Pentek inline filters in stock, H2O offers a wide line of choices in 4 standard sizes, available for immediate shipment. Pentek inline water filters are available with 1/4" & 3/8" FPT connections and many with 1/4" and/or 3/8" John Guest quick-connect fittings built-in.

All Pentek filters are NSF Certified and are made with the highest grade materials available.

These filters are often used as a Reverse Osmosis (RO) inline post filter. They clip on to the membrane housing and filter the water after the bladder tank, acting as a polishing filter.
