Say you have one air purifier and want to purify two rooms for sleeping. Is it possible to pre-purify one room for a few hours in advance, and then move the purifier to the other room? How long does a room stay clean after it's been purified? What would affect this time? Do they need to run continuously to be effective?
(I read through the other Air Purifier thread here, but I'm researching for my family and they are not interested in using box fans!)
