Query: Does what its supposed to

I bought this because I was moving into a nice basement apartment and figured it would be good to get any potentially harmful particles out of the air. I had been looking for one that would cover the square footage that I have and this one was one of the few that could. I wasn't a fan of the price, but I was under the gun and a couple auctions on eBay didn't work out.I haven't had any issues since using this machine. It has been on constantly for about 3 weeks now (I typically keep it low when not home and medium when I am). It does blow cold air out which I don't particularly mind but some might. The apartment is super dusty and unless I have the purifier on high at all times, I know that'll just be something I deal with. I'm more concerned with any mold particles since I'm in a basement.Overall, I think this was a good purchase and hopefully it'll last me for a few years no matter where I go.
