Upgrading ventilation, filtration and other factors helps improve health and cognitive performance

Scientific American – Even though humans have long attributed health benefits to fresh outdoor air, it is a lesson many of us seemed to have largely forgotten… until the COVID-19 pandemic forced us to relearn it. Cleaner indoor air studies have shown that poor ventilation has all kinds of other health effects, from “sick building syndrome” to cognitive impacts.

A lot of attention is paid to the quality of outdoor air but people spend much more time indoors, where we are routinely exposed not just to environmental pollutants but to indoor ones ranging from pathogens to cooking fumes to chemicals released by furniture.

For most homes and small businesses, focusing on ventilation and filtration is probably the easiest way to improve air quality.
