Product review (4 stars): This 250 mesh is way better for filtering my well water.
I use this on my well water supply. The spin-down filter came with 100 mesh, and that just wasn't fine enough to be a good pre-filter on my system, which is what I wanted. My well water has a lot of stuff in it and if I don't use this spin-down filter with this 250 mesh filter in it as a pre-filter to my whole house filters, which this filter feeds, then my whole house filters will clog up very fast.

I flush this mesh out daily or every two days, and so far after a few weeks of operation, i have not yet had to remove this mesh filter to clean it out. It does a great job of catching a lot of the stuff in the water that was clogging up my regular whole house filters.
