Air Duct Cleaners

I live in a basement apartment in the city. Should I get an air cleaner?

Jbonifacio asked: My basement does not have any air-conditioning ducts, but the apartment does come with a dehumidifier. I often keep my windows closed. I always, always have dust bunnies. I don’t think there’s much air circulation. Should I get an air purifier like this: http://www.amazon.com/Sharp-FP-P60CX-Plasmacluster-Air-Purifier/dp/B000KTKSSA/ref=sr_1_3?ie=UTF8&s=home-garden&qid=1241534137&sr=1-3 thanks for the tips!Dryer Vent Cleaning Equipment
