Health and HVAC: How to Combat Back-to-School Germs

Health and HVAC: How to Combat Back-to-School GermsFighting germs with HVAC systems becomes particularly relevant at this time of year. Back-to-school often means back to viruses, bacteria and other common communicable illnesses kids pick up in the crowded classroom. Infection can spread rapidly when introduced into your home environment because most of these microorganisms are airborne. However, this also means fighting germs with HVAC can be one factor in helping maintain a healthy household. Here’s how certain HVAC components, or available additions to the system, can work together to keep indoor air quality germ-free.

Efficient Filtration

Common airborne bacteria and germs come in sizes ranging from 0.5 microns up to 5 microns. High-efficiency pleated HVAC air filters with a MERV (Minimum Efficiency Reporting Value) between 8 and 12 will capture up to 85% of airborne pathogens in the larger range and up to 50% of those down to as small as 1.0 microns. Since all the air in your house circulates through the HVAC filter many times per day, controlling the spread of certain germs by improved filtration is viable.

Humidifier Options

Viruses flourish in dry air with relative humidity below 40%. During winter, low humidity is often the norm, so cold and flu viruses are transmitted more efficiently. Adding a whole-house humidifier to your HVAC system—or using individual room humidifiers—to keep indoor humidity at 50% can have an anti-viral effect on your home environment. Research by the Mayo Clinic proved that operating a humidifier for just one hour can kill about 30% of airborne viruses inside an enclosed structure.

UV Light Technology

Ultraviolet light is another germ-killer that can be added to your HVAC system. Many viruses and bacteria are killed by exposure to ultraviolet wavelengths, a safe component of natural sunlight. UV light tubes specifically designed for HVAC systems can be installed inside home ductwork to continuously expose the circulating airflow to the germicidal effects of ultraviolet light. UV exposure also kills mold spores.
