Model OB3 is OMNI's basic undersink water filter for professional installers. The filter comes with the filter housing, mounting bracket, and a pressure release valve. The filter cartridge, installation hardware, and wrench are sold separately.

If you are a do-it-yourself-er, we recommend you install one of the other undersink models, which comes complete with a filter cartridge and the necessary installation fittings. Change tank O-ring with every second filter cartridge change.
