Choosing the right Omni water filter for your needs

OMNI "do-it-yourself" Undersink and Whole House water filters are designed for easy installation – clamping a saddle valve around your cold water supply line is all there is to installing your filter. However, if you do not want to tap into your cold water line or if you live in a rental unit and cannot tap into the pipes, an OMNI Faucet Mount or Countertop water filter is for you.

“Point of Entry” (POE) Whole House Water Filters

First, we recommend that you install a high-flow Whole House water filter where the water line comes into your home. This Whole House filter will reduce rust and sediment picked up from the pipes that deliver water to your home from your well or municipal water system. This first cleaning of incoming water will protect your appliances (hot water heater, clothes washer, dishwasher, humidifier, toilets, showers, etc.) from the wear caused by rust and sediment in the water. An OMNI Whole House filter will also remove much of the chlorine that can cause itchy skin and damage your clothing.

We recommend OMNIFilter Model U25 as your Whole House filtration system. If you have a large home or high water demands, we recommend OMNIFilter Model BF7.  The OB1 or OB5 is made for professional installation.

“Point of Use” (POU) Water Filters

Then we recommend you install an OMNI high-contaminant-removal filter in your kitchen (or bathroom) where water is used for cooking and drinking. Called “Point of Use” filters, these units remove contaminants and provide clean, safe, great tasting water on demand. Select from our:

Whole House  l  Under Sink  l  Counter Top/Faucet  l Fridge Ice Maker

How to Choose an OMNI Undersink Water Filter

OMNI Undersink water filters “polish” your water by reducing rust and sediment, odors and chlorine, lead, bacteria, and volatile organic compounds (VOCs), including pesticides like lindane and herbicides like atrazine. An Undersink water filter in your home will provide you with great tasting water for drinking, cooking, and making beverages like coffee, tea, and juices!

These are easy Do-It-Yourself Kits.  The new filter change alarm is part of the CBF20 filter.  The Omni SFM2 filter is a simple economic filter. The CBF1 and CBF3 protects against harmful Giardia and Cryptosporidium bacteria.  The OT32 filters rust and sediment.

How to Choose an OMNI Faucet Mount Water Filter

For a low-cost, entry-level water filter, the OMNI F1 Faucet Mount unit will give you great tasting water at the end of your tap. Plus, it takes only minutes to install.

How to Choose an OMNI Refrigerator/Icemaker Water Filter

The OMNI R200 Refrigerator/Icemaker filters will make your ice cubes taste great and take that chlorine taste and odor out of your cold drinks. The only difference in the three models is the way they attach to the 1/4" tubing behind your refrigerator. See each product page for details.
