Having bought a heavy-duty air cleaner (asthma in the family), it occurred to me that I could run it in the laundry room/darkroom while developing and drying film. It's a Friedrich electrostatic model. and the Consumer Reports review adds a side note that electrostatic air cleaners sometimes cause dust to stick to walls.(posted 8066 days ago)Has anyone had experience drying film in a room with an electrostatic air cleaner running?
