>I was wondering if anyone has tried an air purifier in a [large] room... I have a Hunter air cleaner I got from Sam's Club in my animal room. The room is about 10X12 and has two dog crates, one large cockatoo, a zillion zebra finches and five ferrets living there. The air cleaner is on all the time and really helps. One tip - be sure to buy extra filters before you need them - all that fur and feathers really clogs up fast. I recently bought an air conditioner for the room too (mainly for the ferrets) and that helps as well. Good luck. Jean [Posted in FML issue 3501]
