Fake Water Filters on Amazon: How Widespread Is the Problem?
Counterfeit refrigerator water filters are one of the most dangerous fakes sold online, because you can't see what they fail to remove. In industry testing, every one of 32 counterfeit filters failed lead-removal standards, and some leached harmful chemicals into the water. Amazon itself has sued sellers of fake GE filters. Here's how widespread the problem is.
Key takeaways
- No public figure shows how many water filter listings on Amazon are counterfeit.
- In 2018 testing for appliance makers, all 32 counterfeit filters tested for lead failed NSF/ANSI standards over two filter lifecycles.
- Seven of eight counterfeit filters failed to remove 90% of cysts, and some fakes contained burnt peanut shells and rocks.
- Amazon, GE and GE Appliances jointly sued 16 defendants over counterfeit GE water filters.
- Buy filters from Amazon.com, the appliance maker or authorized sellers, and verify certification on NSF's website.
Fake water filters are counterfeits sold as brand-name filters, often with fake certification marks. Compatible filters sold under their own brand are legal, but you should verify their certification independently.
