Can we assume that the air of a specific room is SAFE if we use a good HEPA air purifier in that very room?
I use the whirlpool whispure
I mean its probably "safER" if nothing else
personally I like the washable filters as the mold spores get trapped in the permanent (un-washable) filters and can then breed and repopulate. Wash the filter, then hit it with some isopropyl to kill the baddies
