Not all replacement refrigerator water filters are created equal, even those that may appear from the outside to be exactly alike. Unfortunately, many counterfeit and deceptively labeled water filters manage to find their way into the U.S. It’s a stretch at best to call these knock-offs “filters,” and the tests show it. If you’re wondering what’s inside the phony filters, it varies. Some contain no more than shredded newspaper.
As part of AHAM’s Filter It Out campaign, experts conducted tests of legitimate replacement water filters versus a counterfeit. This photo hows the results of the testing, which was performed by NSF International.
The good news is that since many of the counterfeits are sold online by independent sellers, you can reduce the likelihood a counterfeit water filter will end up in your refrigerator by purchasing your replacements from reputable sources. And remember to replace your filter every six months with a model from a manufacturer who will stand behind its products.
