US Green Building Council and ASHRAE Fact Sheet Tips for Smarter HVAC Filtration and Cleaner Air In Schools

School indoor air quality affects millions of students daily, yet many educational facilities still rely on outdated filtration systems that fail to protect against many common airborne contaminants. With growing awareness of how air quality impacts student health and academic performance, schools need practical guidance on upgrading their HVAC filtration systems effectively.

A recent fact sheet published by the U.S. Green Building Council (USGBC) offers vital insights for school administrators facing challenges in updating their schools’ air filtration technology. This installment in the “School Indoor Air Quality Fact Sheets” series was developed in collaboration with Flu Lab, ASHRAE, and air filtration experts from leading companies and educational institutions in the field.

Proper air filtration and well-planned ventilation can significantly reduce respiratory illnesses, improve cognitive function, and help schools operate safely during wildfire events. The challenge isn’t whether to upgrade; it’s knowing which filters work best for your specific system without overwhelming your equipment.

Understanding MERV Ratings and Filter Efficiency

MERV (Minimum Efficiency Reporting Value) ratings measure a filter’s ability to capture particles of various sizes. Efficiency is indicated numerically with MERV 1 providing the lowest efficiency and MERV 16 indicating the highest efficiency. School HVAC systems have historically used MERV 8 panel filters. Filters with a MERV value of...
