Our one-size-fits-all refrigerator filter / ice maker filter / dispenser filter works on any appliance that dispenses water or makes ice. If the water or ice from your fridge has an odor or an unpleasant taste, it’s likely due to chlorine or organic compounds. Our AC-3k solves that problem by eliminating contaminants with KDF media and GAC (granular activated carbon). Here are just some of the ways in which you can use this filter cartridge:

Refrigerator Filter

Before your water ever enters your refrigerator, it’s already filtered. The internal filter that came with your fridge…you know, the expensive one that you have to replace too often, you won’t need that anymore. The AC-3K is good for 3,000 gallons, which equates to about 2-3 years in most households.

Ice Maker Filter

Bad ice will spoil even the best-tasting drinks. Keep your ice and your drinks tasting great by installing the AC-3K. It conveniently attaches to the wall or the back of the fridge. It ensures that all the water being used to make ice is already clean and pure before it’s frozen.

Water Dispenser Filter

You can connect the AC-3K to most water dispensers. Instead of lugging around heavy water bottles to mount on top of your dispenser, buy a two-pound AC-3K and you’re good for 2-3 years. No more lugging heavy water bottles around…not for you nor the delivery guy. And if you’re excited about how much effort you’ll save in this transition, you’ll be ecstatic about the money you’ll save.

Awesome Value

After using the AC-3K for three years, you will have spent a little more than $2 per month to keep great-tasting water and ice in your fridge. You and I both know that’s an awesome deal.

Parts & Tools List

refrigerator filter, ice maker filter

• refrigerator filter cartridge (included)

• mounting bracket with screw (included)

• crescent wrench, screwdriver, utility knife and bucket


• This is a bacteriostatic water filter designed to remove contaminants from municipally-treated water.

• This product is designed for COLD WATER ONLY (85°F / 29.4°C)

• Maximum flow rate: 0.5 gallons per minute

• Operating water pressure: 20 psi (1.4 bar) to 60 psi (4.1 bar)

1. Turn off the water supply that’s feeding water to the refrigerator.

2. Determine a convenient location for the filter cartridge.

3. Cut the water line with a utility knife at a 90° angle. The first part of the line should extend from the water supply to the inlet of the filter. Simply insert the end of that line into the white, plastic fitting that is labeled INLET. Push it in until it stops.

4. Point the outlet of the filter cartridge into the bucket and slowly turn on the water supply. Water will fill the cartridge. The water flushes out the fine carbon particles through the outlet and into the bucket. The water will be dark and then cloudy. Continue this flushing process until the water is clear.

5. The other part of the line should extend from the outlet of the filter to the refrigerator. Again, while the water is turned off, simply insert the tubing into the outlet fitting.

6. Mount the holding bracket in your desired location and snap the filter in place. Slowly turn on the water and check for leaks.
