Product review (5 stars): Don't Cut Corners on Filters
Have purchase this product over and over and have never had a problem. I once tried a knock-off brand and noticed an immediate drop off in the taste of the water. It was so noticeably bad that I ordered one of these and threw away the knock-off as soon as the replacement arrived. I'm very careful with money and often buy knock-offs, but sometimes they don't pay. For this product, stick with the brand name.
