We have used 3 of these in the last 18 months and still had bad water. It turns out they only reduced the chlorine taste. It did not remove any sediment (particulates, class 1) or any of the other stuff it claims. I had the water in our home tested by 3 different labs, including the local water company, and all tests showed little to no reduction in anything other than chlorine versus our regular tap water. $33.99 carbon filter? No thanks. Installed an RO system and pulled this from our fridge. Invest in a real Reverse Osmosis System is my recommendation.
