We recently moved into our house and thought the water quality was okay. I purchased the 2 stage filter to improve the quality of the water. We noticed an improvement right away, but after a couple of months we noticed a reduced flow. I called support at ISpring to get help and was connected right away with Sean. I sent him pictures of the first stage filter and he noticed the problem and also recommended a spin down filter to help with our water. The filters are great for the quality of the water, but having the support and help from Sean makes this product 5 out of 5 stars, Thanks Sean. Bill. Grayslake, IL. Sun May 17 2026
