How Do UV Light Indoor Air Quality Products Work?

April 19, 2021

UV lamps emit UVC radiation to disinfect nonporous surfaces, air, and water. For many years, UVC radiation has been used to reduce the spread of viruses and bacteria such as tuberculosis. Thanks to their ability to kill microorganisms, these lamps are referred to as germicidal lamps. What Determines the Effectiveness of UV Lamps? The ability of a lamp to destroy microorganisms has a few limitations. For starters, for a lamp to damage the coating of viruses and the DNA of other microorganisms, the organism has to be directly exposed to the light. The lamp needs to shine on the organisms to damage their coat or their DNA. Most of these units install in the HVAC system of your home where they clean air that flows over the coils or through the ducts. The duration of exposure also determines how effectively the lamp kills microorganisms. Most of the lamps used in homes are of low dose, and they may take longer to inactivate microorganisms. As such, the air needs to circulate through the HVAC system severally for the lamp to inactivate all the microbes. The wavelength of the UV light emitted also determines the effectiveness of the lamp. Short-wavelength light (UVC)...

The EPA minimum standard for a cooling system in Missouri is a 13 SEER rating. However, the number can go up to 25. The most energy-efficient systems today can attain ratings of 20 or more. Most homes still have cooling systems with a SEER rating of 10 or less. As the system ages, its efficiency goes down considerably. If your AC unit is older than a...

5 Steps to Better Indoor Air Quality

January 22, 2021

Poor indoor air quality is often to blame for a runny nose, itchy eyes, or asthma attacks. Indoor air pollutants come from many sources. Dust, pet dander and fur, pollen, mold spores, volatile organic compounds, and excess humidity are common types of indoor pollutants. Most homes don’t have all of these pollutants at once, but one or more of them could bother you or even threaten your health. No one is helpless in the face of these irritants.

The filter also serves to protect your heating system by preventing a troublesome buildup of dirt that will interfere with heating equipment operation. When filters go unchanged, air ceases to move easily through the system. Your furnace...
