Maintaining good indoor air quality requires eliminating organic indoor air pollutants such as spores, pollen and microorganisms. One of the best ways to accomplish this is to use a UV air purifier. In this blog, local HVAC service company ACS shares a look at how they work and how effective they are
How Do UV Air Purifiers Work?
Ultraviolet (UV) radiation has natural sterilizing properties, which is why it’s used in hospitals for sterilizing equipment such as scalpels. Advanced water sterilization systems likewise use UV rays to eliminate microorganisms in the water. UV radiation doesn’t emit heat nor does it require the use of chemicals, making it ideal for use on sensitive objects.
UV air purifiers work by sterilizing the air that passes within the range of a specially-designed UV lamp. It can be installed by the cooling coils, sterilizing the air as it gets cooled. Certain types of UV air purifiers can be installed in front of air filters. Larger facilities may require large standalone UV air purifiers, most of which are designed to be installed along with (or retrofitted to) HVAC systems during HVAC installation.
Features and Benefits of UV Air Purifiers
Adding a UV air purifier to your HVAC system has several benefits:
It Eliminates Pollutants That Air Filters Miss — Microorganisms such as bacteria and viruses are much smaller compared to dust and pollen and may pass through standard air filters. UV air purifiers destroy such microorganisms before they reach air filters, resulting in much cleaner indoor air.
It Helps Reduce Strain on the HVAC System — While options such as High Efficiency Particulate Air (HEPA) filters exist, they may restrict airflow if not matched with the right HVAC system. This can place more strain on the HVAC system, which can increase the risk of unexpected breakdowns, as well as higher energy bills.
It Helps Prevent Odors in the Air Ducts — UV air purifiers also help prevent mold and bacteria from contaminating the air ducts, which often results in noticeable odors.
