This filter was installed 9/10/16 and seems to be working fine. The life of this filter is stated as 10,000 gallons of chlorinated water or ? if no chlorine. Since I am filtering rainwater (no chlorine), I've yet to establish the useful life of the filter. If it will last 3 months, that's as good as the filter its replacing. So for now I'll rate the filter at 5 stars.
