Bought this replacement filter for our new rental, with an indoor whole house system. Well tested fine but water smelled pretty bad. Once I got the filter in and the lines flushed their was a noticeable difference. The smell was very faint and acceptable. Now 2 weeks later the smell is coming back in force and getting worse every day. I honestly think unless I can fine a better filter I'm going to have to replace this every 3-4 weeks which is ridiculous. I'm not impressed at all, I was hoping for 3 months a the minimum. At least the price is decent, so it get an extra star for that.
