Filter was improperly installed, so it appeared to have no filter in it, but when the ice came lose from the bottom the filter dropped down. Completely clogged. Just installed new filter, AC on, turned on the o3 gen to clean the air, and the small fans been blowing on it all night. It's Dry except the return box and it looks like it getting there.
Due to the type of work we do, we should inspect/change filters the first of the month, a 3 pack at home depot cost $9.80.
