Actual CO2 level in my home, which ~0.3 air changes per hour for the room I'm in This is typical for homes in US and not enough to prevent airborne transmission *if* you're getting together with others: -Open windows, even 2-3 inches -Masks -Air cleaners -Best: outside

CO2 was >1200 ppm after 2.5 hr in classroom, but dropped <600 ppm after kids went to recess and teacher opened window, placed fan in it. Kept window open, and CO2 stayed around 600 ppm (good target) after kids returned. This should greatly reduce risk of transmission. See thread.

Today was a landmark case, a 7 year fight has resulted in air pollution being recognised on Ella’s death certificate. Hopefully this will mean mean many more children’s lives being saved. Thank you everyone for your continued support.

1/ Clean Air Delivery Rate (CADR). The CADR of a portable filtration system is: CADR = f x Q. f is the fractional removal efficiency of particles that pass through a device (value = 0 to 1). Q is the volumetric flow rate of air through the device (e.g., m3/hr, ft3/min). ...
