Spring is allergy season, when the pollen count rises as the weather remains warmer for longer periods of time. There are a number of ways to help your household deal with the allergic reactions and asthma troubles that often occur during this season, such as air filters and air purifiers. However, if your home’s specific air quality problem is related to germs, viruses, molds spores and various microorganisms, the best protection is to call professionals to install UV germicidal lights, a.k.a. a UV air purifier.
What UV germicidal lights do
UV germicidal lights consist of lamps that send out ultraviolet radiation. The lamps are integrated into the HVAC system so they shine onto the air conditioning coils. This radiation is harmful to organic cells, since it disrupts their DNA, either rendering them inert and unable to reproduce, or else killing them outright. When properly installed, a UV air purifier will prevent mold and bacteria from forming over the air conditioner’s evaporator coils (the most common place for them to develop) and from moving through the rest of the ductwork.
Why the UV air purifier is a good choice for this job
There are air filters that can trap bacteria, mold spores, and other organic pollutants so they won’t flow through your air. However, these filters have a few drawbacks that make them less desirable than using UV germicidal lights. For one, they won’t remove the contaminants from over the evaporator coil, and therefore they won’t help increase air conditioning efficiency. For another, the air filters capable of stopping such small particles (such as HEPA filters) are so tightly woven that they place resistance against the airflow from the HVAC system, severely limiting it. These filters are more appropriate for commercial buildings with powerful blowers, not for homes.
Contact professional indoor air quality technicians if you think your house is suffering from health issues due to organic contaminants. They can help you decide if UV germicidal lights are a good choice.
