re: Filter box for shop mini-split

I did something similar with my mini-split at my other shop after seeing how much crud built up on the fins.  I used some wide weather stripping that has the adhesive on one face along the bottom of the filter box where it butted up to the mini split.  Once I get a mini-split for the new shop I'll do the same thing.  I'm contemplating a ceiling mounted high air flow air filter since it doesn't use the fancy and really expensive filters like the Jet filters.
