How Do UV Light Indoor Air Quality Products Work?
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)...View Article Read More
