Because UV lights kill microbes, mold spores and viruses, your family will be less prone to colds and flu, and reports indicate that allergy symptoms can be greatly reduced. UV lights may also be helpful for those with respiratory problems, pulmonary disease, COPD and asthma because they neutralize germs that can irritate the throat and lungs. The lights also keep your air conditioner clean, so the unit will be more effective and efficient in its life span.
