The importance of UV for maintaining a healthy air quality for family members and office workers cannot be overstated. Even air filtration units using HEPA cannot control disease carrying microbes. HEPA will trap bacteria. It won't destroy it. Trapped organisms can eventually seep back into the air.
Viruses can actually pass through the filter.
Inside the C.A.R.E. 2000, the HEPA is continually bathed in UV light. Bacterial and viral microorganisms such as hepatitis, influenza, TB, and Legionnaire's Disease are trapped and destroyed before they can infiltrate your air space . Designed and built for longevity and easy operation. The entire unit weighs only 34 lbs. The accessible UV lamps are 9 watts apiece, and provide 9,000 hours of protection.
