Lifting the Veil on the Refrigerator Water Filter

Nov 15 2022
In the United States, approximately 4 to 32 million Americans fall victim to waterborne diseases each year. Contaminants like lead, chlorine, cryptosporidium, and fluoride find their way into your faucets every day without filters in place.

When it comes to filters in refrigerators, most come with built-in filters. But how do these filters work, what do they filter out, and can we count on them to get the job done?

How they work
But let's start with your local water treatment plant and understand the path water takes from pipe to glass.

Tap water from local water treatment plants often contains contaminants such as chlorine or chloramines. These chemicals are often used to treat the water itself and remove pollutants that can make people sick. However, even after removing the bacteria, numerous studies have shown that traces of drugs, lead, and even potentially disease-causing bacteria remain, including chlorine-resistant cysts such as Giardia and Cryptosporidium. Additionally, heavy metals such as mercury and lead can be found in drinking water in parts of the country where some of the infrastructure is abandoned and more messy.

A 4396841 water filter installed in your home, from the city to your refrigerator, can help remove some of the pollutants we mentioned above (like chlorine taste and odor), but it won't completely remove everything else. While it's hard work, an overused filter in your refrigerator, especially one that isn't replaced often enough, won't properly remove harmful substances still present in your water. Water passing through an old, overused filter can even carry some trapped contaminants back into your drinking water. On top of that, not all refrigerators have lights to let you know it needs to be refilled.

Can we count on them to get the job done?
The biggest problem with refrigerator filters is not the actual filter, but the dispenser itself. A 2013 study by the National Sanitation Foundation of the most germ-growing spots in the kitchen found that most refrigerator water dispensers were coated with "certain levels" of yeast and mold. This may not be the most common definition of healthy, clean water.

Rather than using an expensive refrigerator replacement filter made by the original manufacturer of the refrigerator itself, invest in a edr2rxd1 water filter whirlpool that removes more contaminants before it enters the refrigerator. Find a filter that removes the pollutants that matter most to you. Make sure to look for an NSF-certified water filter to ensure proper removal of contaminants. As you make your chore list, you can also make a mental note to clean the water cooler itself. Clean, healthy water, ice, and a water dispenser - now sounds like a healthy, happy home.
