Most refrigerators these days come equipped with a water filter that dispenses both drinking water and ice. The use of a water filter has many benefits compared to water straight from of the tap. Using refrigerator water filters saves money and is better for your overall health and the environment. It also saves you the inconvenience of going out and buying bottled water that is bulky and awkward to carry around. But are they effective at producing clean drinking water? It really all depends on the type and quality of your water filter and your tolerance in terms of water quality. But before you go racing out the door to buy one, consider your options. You will need to understand what it is water filters remove and how effective they are at this job. Several factors such as filter media, quality of the water filter, and composition of contaminants from local water sources all play a role in the water purifying process.


To answer this question, not very clean at all. Consider the fact that most unfiltered drinking water contains 100s of contaminants and pollutants. Water out of the faucet is usually riddled with things like heavy metals, bacteria, viruses, pharmaceutical drugs, and carcinogens. What about well water? Well water typically isn’t surveyed or reported so the purity is largely unknown. However, of the tests conducted on well water, it was confirmed that the quality was not much different than municipal water. And bottled water? Even though words like “natural” and “spring” appear on the labeling, it’s been known a lot of brands contain nothing more than filtered city water. What’s so natural about that? Additionally, most water supplies also have fluoride added. While some have no problem with this, others argue that increased fluoride in the body can lead to health problems like thyroid disorders and impaired brain development and function.


In order to know this, it requires understanding of a few variables. The quality of water produced by a filter will depend on how impure the existing water is along with the quality of the filter itself and the media used. To begin with, a household must know which impurities currently exist in their water source. By contacting their local water municipality, a water report can be requested. However, most municipalities only test for around 90 substances and organisms. Their job is to only make sure the water is at least potable. The responsibility then falls on the homeowner to do their own thorough test for contaminants or send a sample to a third party tester.

When selecting a refrigerator water filter be sure to find out if the filter has been tested by a third party. Read the full report and look for transparent language than not only states what it removes but in what percentages. Most filter manufacturers disclose vague information, leaving one wondering. The carbon filter in filter units does a great job removing most contaminants but substances like fluoride and chloramine, among others, are not removed. Adding a reverse osmosis membrane will help removed nearly all other pollutants but fluoride removal will need its own dedicated filter in most cases.


Refrigerator filters can be a great resource for ensuring your family is getting clean drinking water. There are so many benefits such as improved overall health, less impact on the environment and financial savings, among others. Additionally, be sure to read all city water reports and manufacturer filtration ratings when deciding on purchasing water filters. Experts suggest changing your water filter twice a year to promote proper filtration. A refrigerator filtration system can pump out several thousand bottles of water, which saves you roughly $600 in costs yearly as opposed to buying branded bottled water. Despite what may be found in your water source, with the proper refrigerator filters you can be sure to remove nearly 99% of contaminants at home.

Experts say that water filters in your fridge should be changed twice a year. Otherwise, you and your family may be unknowingly consuming unclean water. Or worse, the water filter could be leeching concentrated contaminants back into your water.
