Are UV Lights Really Beneficial for Air Quality?

What are UV Lights for Ductwork?

UV lights kill germs and bacteria and can be used for sanitizing the air if placed in the HVAC ductwork. These vary in size, amps, voltage, and safety features. They are VERY effective for Improving Indoor Air Quality

I’m thrilled with my UV light! I used to have terrible allergies and now I breathe easy!

What can UV Lights do?

• UV lights can eliminate fungi, bacteria, germs, viruses, mold, and pathogens which reduce allergy symptoms
• UV lights improve air quality within the HVAC system by killing any harmful bacteria in the ductwork before they enter the air you breathe. These lights stop disease-causing microbes from circulating throughout your home.
• They improve airflow and efficiency.
• These lights are frequently used in hospitals to keep the air as sanitary as possible.

How Do UV lights Work?

• UV lights emit wavelengths that destroy microbes and pathogens. These wavelengths prevent disease and microorganisms from thriving in the otherwise hospitable environment of the HVAC ductwork.
• The lights sterilize by a process called Ultraviolet Germicidal Irradiation (UVGI). This method uses short-wavelength UV light to destroy microorganisms by targeting their nucleic acids and effecting their DNA, making them incapable of preforming their basic functions. In a circulating environment, such as HVAC systems, the UV waves are strong enough to create inhospitable environments for these organisms.
• Coil sterilization is a type of UV light that operates 24/7 and sterilizes the air handler coil. UV lights can improve the efficiency by eliminating biofilm in coils. Biofilms and bacteria build up can reduce performance by slowing the airflow and clogging the coils.
• Air sterilization is a type of UV light unit that sterilizes air as it moves. This light is installed in the return duct and comes on with the air handler.
• The purpose of any type of UV sterilization is to eliminate and prevent the growth of microorganisms within the HVAC ducting.
