Refrigerator/In Line

The standard water filter inside your fridge does not filter fluoride. It will filter chlorine, heavy metals, and other contaminants, but not fluoride. We offer refrigerator fluoride filters that work with your existing fridge filter. They install inline, along the cold-water line that goes to your refrigerator allowing you to have fluoride-free ice and water. Installation can be behind your fridge, anywhere along that water line, inside a cupboard, or in the basement below the fridge.

There are two types of refrigerator fluoride filters:

If you are happy with the contaminants your existing fridge filter removes and just want to filter fluoride. The Fluoride Only water filter system is your best option. It uses Bone-Char to filter fluoride.

If you don’t have an existing fridge filter or you are not happy with the taste and would like to filter more contaminants, the Fluoride Multi Plus is the best choice. It uses Bone-Char combined with our smart media to filter a wide range of contaminants including chlorine, PFAs, heavy metals and pesticides.

Refrigerator/in-line fluoride filters are installed on the cold water line feeding your refrigerator, ice maker, or dispenser. Instead of relying on a small cartridge inside the refrigerator, the water is filtered before it ever enters the fridge. This makes the system compatible with virtually any brand or model of refrigerator that uses a standard 1/4" water line.

Inside the system, water passes through dedicated fluoride reduction media and additional filtration stages (on the Multi PLUS model) that target chlorine, chloramines, heavy metals, sediment, and many other contaminants. The result is cleaner, better-tasting water and ice directly from your refrigerator.

A properly sized and installed refrigerator/in-line filter should not significantly reduce your water pressure or ice production. These systems are designed for standard household refrigerator and ice maker flows, and most customers notice only that the water and ice taste better and smell cleaner.

If you do experience a noticeable slowdown in flow or smaller ice cubes over time, it usually indicates that the filter has captured a lot of sediment and contaminants and is ready to be replaced. Checking for kinks or tight bends in the tubing and following the recommended replacement schedule will help keep your fridge water and ice running smoothly.

The Fluoride Only system should be replaced yearly.

The Fluoride Multi Plus system should be replaced every 9 months

We always recommend checking the “Replacement Schedule tab” on the product page for the specific system you own. There you’ll see the exact part number, expected lifespan and a clear schedule to follow. If you notice a drop-in flow rate or a return of off-tastes or odors sooner than expected, it is usually a sign that the cartridge is due for replacement.

Installation should be done by a licensed, local plumber. It is a very simple job for a plumber. It can be installed behind the fridge. If there is not space it can be installed anywhere along the cold-water line that goes to the fridge. This can be in a near by cupboard or even in the basement. Cartridge replacement does not require a plumber.

If you have an under sink filtration system you can split the product water line and run that to your refrigerator. This will work as long as there is a practical way to run that water line from under the sink to the fridge. If that is not an option, a separate refrigerator filter is needed.
