We have 2 large blue ones that we use in well water in the Central Valley of California. When we changed the original filters after 3 months, we decided to do it. Worked well, not spectacular. Removed a lot of sand/dirt. I hosed it down every month and went back to the original paper filter after about 3 months to see if it worked better. 3 stars because it was ok and a lot of sand was removed. Didn't tear when I hosed it down and put it back in the big blue every month. I think I expected more.
