Whole House Water Filter - Model OB5
The OB5 is OMNI's basic whole house water filter for professional installers, but it comes with a clear housing. The filter cartridge and installation hardware are sold separately. A wrench is included. 

With its 3/4" NPT, the OB5 whole house water filter can be installed on standard plumbing pipe.

If you are a do-it-yourself-er, we recommend you install Model U25 as your whole house system.  It comes complete with a filter cartridge and installation fittings.
