These filters should work for 6 months. One is installed under our kitchen sink so we use it a lot - after 10 months it's still working. The other didn't even last 2 months in our sink (so much easier to deal with) before I noticed that the water not only smelled strongly of chlorine but was actually gross like bacteria was growing in the filter or something. It was gross and made me wonder what we've been drinking for the past few weeks. Unfortunately bought too long to return but I will avoid this brand in the future.
