If you've achieved the coveted tight building envelope, you're now in need of indoor air quality solutions. The 24V UV Air Purifier with AirBright is one that installs within the HVAC ductwork, zapping mold spores and killing bacteria circulating through the system. In addition to the low-voltage UV light, Honeywell's odor-neutralizing AirBright component converts VOC's into CO2 before passing through the cooling unit, removing odors from cooking or pets. Comes with a five-year warranty. www.yourhome.honeywell.com
