The 10 Best MWF Water Filters

video play icon

This wiki has been updated 16 times since it was first published in November of 2018. Clean water is essential for your and your family's health, and some General Electric refrigerators use an MWF filter to ensure that what they dispense is free from contaminants, such as lead and mercury. However, when it comes time to replace it, you'll find tons of cheap knockoffs on the market, so we've compiled a list of quality models with a range of prices and filtration levels. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki. If you'd like to contribute your own research to the Wiki, please get started by reviewing this introductory video.

Editor's Notes

November 25, 2020:

We have removed the AmazonBasics MWF-P3 and Blue Signature GES because they are no longer available. We added the Best GE MWF Compatible as a decent, less expensive alternative to the General Electric MWF. The trade-off is that it is not quite as effective as the brand name filter, because it does not hold the NSF 53 certification, so it may not reduce lead and other heavy metals or volatile organic compounds. The Icepure Pro has been added because it meets many standards in addition to the NSF standards, but one drawback is that it does not remove pharmaceuticals. Glacier Fresh has been added due to its comprehensive filtering capabilities, but it has limited compatibility with General Electric refrigerator models. The Aqua Crest meets many of the standards to filter harmful substances including the especially harmful trihalomethanes (THMs), and the housing is made of safe materials. Be aware that you may need to periodically reset the filter to maintain an acceptable flow rate and this can be a minor inconvenience.

One of the main things to look for when shopping for an MWF water filter is whether it has been certified by the nonprofit National Sanitation Foundation to reduce impurities. Because attaining these certifications can be expensive, some companies opt instead to hire third-party laboratories to test their filters against the NSF standards. The General Electric MWF, for example, is not NSF certified to reduce trace pharmaceuticals, but the manufacturer says testing from an independent laboratory confirmed it still conforms with the nonprofit's standards.

For some consumers, this may lend less credibility to claims that a filter reduces or removes certain contaminants.

Also keep in mind that the NSF issues various types of certifications. An NSF 401 certification means a filter reduces the level of incidental contaminants, such as prescription drugs and pesticides. NSF 53 relates to health-related contaminants, including lead, benzene, and carbofuran. An NSF 42 filter will improve your water's aesthetic, reducing chlorine, foul tastes and funky odors.

Finally, a filter can have an NSF 372 certification, like the Waterdrop Plus, which means it is constructed from lead-free materials.

These certifications were the main factor we considered when ranking these filters, though we also looked at ease of installation, water flow rate and price.
