Refrigerators with built-in water filters appear like a brilliant deal—you want a refrigerator anyway, so why not purchase one that filters your water? While really better than nothing, refrigerator filters have widespread boundaries when compared to devoted total house or countertop filtration systems.
Size Matters
Most built-in refrigerator filters use activated carbon as filtration medium. Such filters work via a method referred to as adsorption, which reasons contaminants to stick to the filtration media. Activated carbon is honeycombed with nooks and crannies, so it affords a large surface location for adsorption.
Two concerns determine how efficiently activated charcoal filters reduce contaminants: size, and how long the water remains in contact with the filter medium. In small filtration systems, such as built-in refrigerator filters, the quantity of filtration media is via necessity limited. The size of the filter also skill water spends a minimal amount of time in contact with the carbon, as opposed to the plenty large filter structures located in point-of-entry and countertop filtration systems.

What Gets Filtered? What do Refrigerator Water Filters Remove?
Activated charcoal eliminates chlorine, unstable natural chemicals, radon, benzene, and many different man-made chemicals, as properly as bad tastes and odors. Within the limits of their small size, built-in fridge filters do a honest job of doing away with these threats, although less efficiently than large systems. Activated charcoal alone, however, isn’t adequate to put off all waterborne contaminants.
Carbon filters provide little to no safety against a extensive vary of inorganic contaminants and heavy metals, consisting of threats such as:
- Arsenic
- Barium
- Beryllium
- Cadmium
- Chromium
- Copper
- Fluoride
- Mercury
- Nickel
- Selenium
- Sulfates
- Thallium
Highly specialized activated charcoal filters can do away with lead, but such filters are rarely found in fridge units. Minerals, lead, and different heavy metals can be eliminated by way of reverse osmosis filters. Frigidaire WF3CB Water Filter
Convenience Issues
Limited Filter Lifespans = More Cost
At first glance, a built-in refrigerator gadget may also seem convenient, however remember, it only provides filtered water in one location—your kitchen. A complete residence filter offers cleaner, safer water from any faucet in the house, whether you’re cooking, cleaning dishes, bathing, or washing clothes.
Built-in refrigerator filter systems have one ultimate difficulty to consider: filter alternative costs. Because activated charcoal filters work by way of adsorption, they subsequently clog up with contaminants and need replacing. This is as real for a whole residence filter as a small fridge filter, with one widespread difference. The dimension of a complete house filter skill you change the filter much much less often, ensuing in less hassle, more convenience, and much less pressure on your bank account and a greater superb water filtration solution.
