How do refrigerator water filters work?

2021 Nov 19th

Part of caring for your family is making sure your recipes and their cups have clean, fresh-tasting water. Most refrigerator water dispensers make it easy to access clean water that's been through a triple filtration process.

The filtration process explained

Refrigerator filters force water through three stages that trap dangerous contaminants, pollutants and particles found in many city water sources.


Help block larger contaminants like sand and silt.


Help capture medium-sized contaminants like sugars and cysts.


Help adsorb microscopic contaminants like atoms, ions or molecules from a gas.

How well do refrigerator water filters work?

Whirlpool® brand refrigerators work with everydrop® water filters that use activated carbon from coconut shells to reduce up to 73 contaminants and capture 99.9% of lead1. Activated carbon functions like a contaminant magnet, trapping lead, pesticides and pharmaceuticals. The coconut shell design even helps remove contaminants that affect taste, like chlorine and iron.

Care Tip: Replace your filter every 6 months and only consider filters certified by NSF International*.

*NSF International is an accredited, independent third-party certification body that tests and certifies products to verify they meet these public health and safety standards.

Everydrop® filters take roughly 5 minutes to install. Look for the colored number on your filter and consider purchasing a subscription to automatically ship a replacement filter every three or six months. Whirlpool can also help you change your filter.
