Indoor air quality (IAQ) is a fundamental yet frequently underestimated aspect of public health, especially highlighted by the COVID-19 pandemic. This often-neglected facet impacts health, productivity, and learning. In an article published in SCIENCE, 40+ international experts, including Professor Joseph Allen, Director of Harvard’s Healthy Buildings program, call for national IAQ standards and provide a roadmap for healthier […]

In this article, we discuss the basics of air cleaning and filtration, how to build your own portable air cleaner, and some performance enhancement considerations. There are three main approaches for improving indoor air quality: (i) reducing sources of indoor air pollution, (ii) dilution ventilation, and (iii) air cleaning. Air cleaners are generally used to […]

Last week, the Biden-Harris administration hosted the White House Summit on Sustainable and Healthy K-12 School Buildings and Grounds.
