ASHRAE Standards for Indoor Air Quality

People see how indoor air quality affects health, energy use, and building performance. And professionals are looking to ASHRAE for guidance.

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

Good indoor air quality is important. ASHRAE standards help ensure the air we breathe—at school, work, home, or in healthcare settings—is clean, safe, and healthy.

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

As climate-related air quality threats increase, ASHRAE Guideline 44 has emerged as an essential tool. It offers practical strategies to protect building occupants from wildfire and prescribed burn smoke. These include enhanced filtration, air cleaning technology, and HVAC system 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 offers Plasma Air in-duct bipolar ionization products and Novaerus portable disinfection units, powered by NanoStrike. Together, they help address a wide range of indoor air quality needs. WellAir products support safe environments across schools, hospitals, commercial buildings, and homes.
