As awareness grows around the impact of indoor air quality (IAQ) on human health, energy efficiency, and building performance, industry professionals are turning to a trusted authority for guidance: ASHRAE.

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) develops standards and guidelines that shape how we design, operate, and maintain buildings to support healthier indoor environments.

Whether in schools, hospitals, offices, or homes, ASHRAE standards help ensure the air we breathe indoors is safe, clean, and optimized for human well-being.

Key standards like ASHRAE 62.1 and 62.2 establish minimum ventilation requirements for commercial and residential spaces, while ASHRAE 170 sets strict guidelines for healthcare facilities. ASHRAE 241, one of the most important recent additions, focuses on controlling infectious aerosols to reduce airborne disease transmission.

And as climate-related air quality threats increase, ASHRAE Guideline 44 has emerged as an essential tool—offering practical strategies for protecting building occupants from wildfire and prescribed burn smoke events through enhanced filtration, purification, and HVAC preparedness.

These evolving standards go beyond compliance—they reflect a proactive approach to creating healthier, more resilient spaces. Forward-thinking organizations are already adopting solutions that align with ASHRAE’s direction.

WellAir’s Plasma Air in-duct ionization products and Novaerus portable disinfection units help meet a wide range of IAQ requirements, supporting safe environments across schools, hospitals, commercial buildings, and homes.
