By far the best brand that we have found. It is true to the time. Meaning, I have written the dates of the day we replace the filter on the filter itself and each one has lasted us exactly 6-6.5 months & we use it A LOT! It is our main source of water in the house because we are iffy about consuming the tap water! Great purchase. You can truly taste the difference it makes!
