I work for a company that sells multiple purifying products, one of which is a state of the art air purifier that deodorizes and kills all germs, bacteria, mold, etc in the air AND on the surfaces in a 3000 square foot area. There is very little maintenance required (just changing a piece of the filter once a month that costs 2 dollars) and its yearly running cost is only $85 (including filter maintenance and energy costs.

The unit is called the Fresh Air Surround or Everest. There is also a link to email me on the site if you have questions.
