OK so I know this sounds like a dumb question, but how do I replace the filter in the cabinet above the toilet? I see that it unscrews. I am supposed to replace the filter correct? Where does a person find replacement filters? How often should it be replaced?

Thanks all!

It's more of a strainer to keep out beasties and stuff on the raw water side.

I don't replace it....just rinse it out when winterizing or when it looks like it needs a rinsing.
