The Q-Series filter, manufactured by Omnipure, is an easy-to-install replacement cartridge that twists right into a permanent head.

Omnipure's TQ56-50FC encapsulated membrane is compatible with both PuROTwist 4000 and PuROTwist 3000 Reverse Osmosis systems or any system that uses Omnipure Q-Series filters. It comes with a built-in flow restrictor and check valve and is easy to install.

The Q5640 filter uses reduce chlorine, taste and odor making it ideal for pre- or post RO filtration.

Filters may need to be replaced more often than indicated depending on incoming water contaminant levels and volume of water being treated.
