I found a small area (2-3" square) of black mold in my bedroom which explains why I've been having bad asthma problems. Someone should be coming to clean it for me today; however, I need to purchase an air filtration system. I'd like ionic, has to clean mold in addition to pet dander, dust mites, bacteria, viruses, etc. Needs to be simple and I don't like changing filters. My house is 936 Sq. ft. but my bedroom is the most important place I need this.

We will be checking to make sure no black mold elsewhere. This particular corner wasn't getting air circulation and my room humidifier was just a few feet away so I"m sure that's what happened. I may need a dehumidifier, too, but right now I'm just needing a good HEPA and ionic air cleaner.

I've looked at several on-line at Home depot and found some likely ones. If anyone has a brand/style they can recommend, that could be helpful. Thanks!
