thanks everyone, and Happy New Year! i got the air purifier yesterday, and it is AMAZING! i am so happy with it. the air in my apartment seems much, much fresher. i can really notice the difference. also, the guy next door was smoking the cigar again today (it smells very strongly in the hallway)... but the smell wasn't in my apartment. wooooohoooooo!!! i got the kenmore 83202 83200, and i totally recommend it. we decided on this brand because it was given the second-to-highest rating in consumer reports, some good write-ups/reviews online, and they had it in stock in sears. so far it seems excellent at removing smells. i already notice a HUGE difference. i'm so happy with it! yay!!
thanks again for all of your input... i appreciate it so much!
