HEPA/UVC filter question…

Hello everyone, new to the forum. Need some help deciding on a hepa filter.
I have a 450sq.ft grow room, need a filter that can get rid of pm spores/mold spores. There are few I’m interested in take a look please. Also, are these systems good enough for pm, I don’t want anything that uses PCO (I believe that’s what it’s called) tech. although I know they filter better.
