Chris and Jonathan speak to Joey Fox, an engineer and the chair of the Indoor Air Quality Advisory Group for the Ontario Society of Professional Engineers. COVID-19 is not over, as both Jonathan and Chris can testify. How can we better protect ourselves from the coronavirus and other respiratory viruses? By improving our air! Joey Fox explains the difference between HEPA and MERV filters, why “UV in a box” is not a good idea, and how to make sense of the different air cleaners you can buy (and make yourself!). We all care about clean drinking water. It’s time we cared about clean air as well.
