My wife and I had been using a Brita pitcher filter but had read that it doesn’t filter out as many things as we thought so we did some more research and found that this was the best filtration system after reading blogs from people who have done very thorough research and so we decided to try this one. We are soo happy with our purchase!! It came with great instructions and was really easy to hook up. The water taste soo much cleaner and better. I would highly recommend this filtration system. We are very very thankful for this water system!! Thank you thank you!!!
