Living next to a highway is not great for health, but a new study shows that running air filters indoors can remove tiny particles of pollution and lower blood pressure.
Being indoors with other people is a recipe for spreading the coronavirus. But removing airborne particles through proper ventilation and air filtration can reduce some of that risk.
Good ventilation can reduce the risk of catching coronavirus. An environmental engineer explains how to know if enough outside air is getting into a room and what to do if ventilation is bad.
