Cool and refreshing water from the fridge. It may taste great, but just how effective is a fridge filter? After all, a refrigerator is designed to chill groceries, not eliminate contaminants from your water supply.
How Refrigerator Water Filters Work
The big question at hand 鈥� is fridge water filtered? Yes, but maybe not in the same way you're used to.
Most built-in refrigerator filters as a filtration medium. The process is quite simple. As water flows through the filter, contaminants , removing them from the water. Activated carbon is honeycombed with nooks and crannies, so it provides a large surface area for catching these unwanted particles.
It's an effective system, but it's not foolproof. You need to consider both the size and length of time the water is in contact with the filter. Obviously, bigger filters are able to catch more contaminants and won't fill up as quickly. The filter in your fridge? It won't be that large.
The length of time water spends in contact with the filter is also crucial. You want the water to really have time to soak so the carbon can do its job. Unfortunately, most fridges just don't have the capacity for this.

- Arsenic
- Barium
- Beryllium
- Cadmium
- Chromium
- Copper
- Fluoride
- Mercury
- Nickel
- Selenium
- Sulfates
- Thallium
Highly specialized activated charcoal filters can remove lead, but such filters are rarely found in refrigerator units. Instead, you might consider an upgrade to something more powerful, like a whole house water filter.
