Product review (5 stars): Number 1 Filters!
This filter has already lasted twice as long as any other we have tried and still using it. Over the last 7 years. We will keep getting these for sure. We so learned years ago that what helps these filters last longer is to have a softener added that back washes through your filter and that helps clean it too. But all in all, we have tried several brands of filters and these are number one!
