I bought my Aquagear pitcher in December 2017 and it worked wonderfully for almost a year. After a few months of slow filtering water towards the end of a year of use, I finally ordered a replacement pitcher. It worked great for a month but now hardly works as it filters slower than the original filter that came with the pitcher! Totally unacceptable as for a $50 filter to work for only a month rather than 5-6 months (150 gallons use) as advertised. Luckily requested a replacement due to product defect 3 days before the return window expired so Amazon is sending a free replacement but I anticipate the same problem will happen again. If it does, may be time to invest in a better new water filtration system all together.
