How Do UV Air Purifiers Work?

There are many types of pollutants that get inside a home’s HVAC system and start circulating through the living spaces, lowering the quality of the air you and your family breathe. You can use filtration systems and electronic air purifiers to eliminate most of these pollutants, which include dust, dander, pollen, chemicals, dust mites, and odors.

However, if you have biological contaminants inside your HVAC system—such as molds, viruses, and bacteria—standard air filters and purifiers will not do much good. The best option to eliminate these hazardous organic pests is with a UV air purifier. You can contact an experienced indoor air quality professional to find the right UV air purifiers for your needs and then integrate them into your ventilation system.

The power of ultraviolet light

UV air purifiers do not use any sort of filtration to do their job. Instead, they use rays of ultraviolet light to destroy organic pollutants moving through the ducts. These ultraviolet rays disrupt the DNA of microorganisms and destroy their nucleic acid, which makes it impossible for them to carry out regular cellular functions.

Originally, UV radiation was used in hospitals to aid with sterilization and sanitation. As the technology developed, it moved into residential use. The standard UV air purifier for a home consists of an ultraviolet lamp (a.k.a. germicidal light) that sends out short-wave UV radiation. Although intense UV radiation is harmful to humans, these lights are small enough that they will only pose dangers to contaminants in the HVAC system, not to anyone in your home. Plus, professional installers will see that the lamps are placed where they won’t come into contact with people and are properly shielded to avoid causing corneal damage.
