How are your refrigerator water filters so affordable? 

We know, it's hard to believe! You can go through the big name brands, but you're going to pay the big name brand price.

Why are refrigerator water filters important? 

The water flowing through your refrigerator water dispenser traveled a long way to get to your home. Water may leave your water treatment plant clean and free of toxins, but on its way through old pipes this water can collect lead, mercury, impurities, VOCs, and more. Refrigerator water filters act as the final defense for removing and reducing these unwanted contaminants.

How do I reset that annoying little indicator light on my fridge?

Like everything else in this world, every manufacturer has their own “unique” way of doing things. We’ve included the instructions for how to turn off the water filter indicator light for the most common fridge brands for your convenience.
