How to Choose an OMNI Whole House Water Filter

OMNI Whole House water filters effectively reduce rust, sediment, chlorine, and odors at the point where the water lines enters your home. So the water flowing to all your faucets and appliances is clean and tastes great! We recommend OMNIFilter Model U25 as your Whole House filtration system. If you have a large home or high water demands, we recommend OMNI Filter Model BF7. The OB1 or OB5 is made for professional installation.
