The 8 Best MWF Water Filters
We spent 26 hours on research, videography, and editing, to review the top choices for this wiki. 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 picks, we may earn commissions to support our work. Skip to the best mwf water filter on Amazon.

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.
