What technology can be used to improve indoor air quality in HVAC systems?

Using UV light systems or HEPA filters in HVAC systems significantly contributes to improving indoor air quality.

UV light systems work by harnessing ultraviolet light to kill or deactivate pathogens, such as bacteria, mold, and viruses, that can circulate in the air within an indoor environment. When installed within an HVAC system, these systems can continuously cleanse the air that is circulated, reducing the overall load of airborne contaminants and allergenic particles.

HEPA filters are designed to capture at least 99.97% of particles that are 0.3 microns in size. These filters effectively trap dust, pollen, pet dander, and even some microbes, enhancing the cleanliness of the air being circulated through the HVAC system. By implementing either or both of these technologies, a significant improvement in indoor air quality can be achieved, leading to healthier living conditions for occupants.

In contrast, while carbon dioxide scrubbing systems can help manage specific indoor air quality issues related to CO2 levels, they do not offer the broad spectrum of air quality improvement that UV light and HEPA filters provide. Programmable thermostats primarily enhance energy efficiency and comfort rather than directly impacting air quality. Exhaust fans can help with ventilation but are not as effective as UV lights and HEPA filters in removing
