Ultraviolet Air Purifiers


Ultraviolet Air Purifiers use ultraviolet (or UV) light which is a natural component of sunlight. They utilize the process of Photochemistry to reduce contaminants in the home. Ultraviolet light transforms molecules of water and oxygen into subcomponents of ozone, hydroxyl and hydrogen peroxide.

Ultraviolet Air Purifiers are effective for eliminating viruses, bacteria, mold, fungi, pet dander and other small organisms. Most ultraviolet air purifiers use UV lighting in the range of 185 to 250 nanometers. Less ozone is formed with the lower wavelengths, while longer wavelengths produce more hydroxyl and the best cleaning. A broad spectrum ultraviolet air purifier is the most effective because it uses both short and long wavelengths.

In general, the higher the wattage of the bulb, the more effective is the unit. Care must be taken to keep the bulb clean for maximum efficiency because it is the direct ultraviolet light that destroys the contaminants. The bulb is in continuous use and will likely need frequent replacement especially if it is subjected to shock treatment.

Strengths

  • Great at destroying bacteria, germs, viruses and mold.
  • Quiet operation.
  • Little maintenance required

Weaknesses

  • Will not remove particulates such as dust and pollen.
  • Will not remove gaseous contaminants such as smoke and chemical fumes.
  • Will not remove odors.
