Product review (4 stars): These filters work very well and if you purchase knock-offs at a better price make sure they're NSF certified
Tried a cheap knock-off at first and it leaked after 3 days and the water was still cloudy after dumping about 10 gallons. These filters work very well and if you purchase knock-offs at a better price make sure they're NSF certified. They cost a little more, but at least I know what I'm getting - NSF certified and high grade carbon rather than charcoal powder or worse.
