Product review (2 stars): Worked well, but only lasted a month.
This filter worked well in the beginning. The water tasted & tested well, however this only lasted for just over a month. We use and drink a lot of water in our house, however the product boasted a 6-month longevity or 300 gallons, and it was well under those limits before we had to replace. We use about 1 to 1.5 gallons a day, which means the filter only lasted roughly 45-50 gallons.
