I have been using this filter for almost a year and have been happy with it's performance. I have a well so there is no chlorine issue but it does a good job of removing rust and rotten egg odor. I am not sure how many gals before each filter change, I just change it when I notice a drop in water pressure which is about every 4 months.

this filter seems to be the best i have used for my whole house system. priced a little high for only 5k gal. use, but it works for me. It does reduce bad taste and odor from chlorine and other chemicals in my drinking water and i have been using it exclusively for about ten years with no problems..
