How to clean prefilter for charcoal filter?

Mine is gross. My fan sounds like it is struggling this morning. How do you clean yours? Do you use one at all? Thanks

I just rinse it in hot water, seems ta work fine

Didn't wanna use sope in case it stunk likevit

Cool. Thanks Chris. I will try extra hot h2o. If that fails, I wonder if oxy clean would work? Vinegar maybe?

I'm sure any cleaner would work, oxy for sure
