University of Colorado Boulder researchers have discovered that a specific type of ultraviolet light can disable common airborne allergens within 30 minutes, potentially offering relief to the one-third of Americans who suffer from allergies. Light as Molecular OrigamiThe research team tested their hypothesis in a 350-cubic-foot sealed chamber, pumping in microscopic allergens from dust mites, pet dander, mold, and pollen. Asthma attacks, often triggered by airborne allergens, kill approximately 10 Americans daily and send nearly one million people to emergency rooms annually. The research team acknowledges that clinical trials with sensitized people represent the next crucial step. Where previous studies required weeks or months to achieve similar 20-25 percent allergen reductions, UV light accomplished this in minutes.
