hi, someone was looking for a air cleaner for his family room., i searched for the post and couldnt find it. anyway found a product called a microclene 500 or 1200 preferably that has several reviews from turners etc and seems to do a real good job of cleaning dust, particles and even smoke from a room. it seems like its only sold in England however as I cant find a seller in the U.S. saw prices from 175. to 200 pounds I guess so I dont know what that means in dollars. if your interested, hope this help.s
