Controlling Air Quality Is Critical

I have been arguing we need more

ventilation to provide healthy indoor

Humidification gives people a

simple means of actively combatting

seasonal respiratory infections,

including the fearsome SARS-CoV-2 virus

Relative humidity of 40-60% in buildings will reduce respiratory infections and save lives.

Avoid crowds. The more people around you,

the more likely someone among them will be

infected. Especially avoid crowds indoors,

where aerosols can accumulate. 

Ventilation counts. Open windows and doors.

Adjust dampers in air-conditioning and heating systems.

Upgrade the filters in those systems

When you recirculate that air, you have to be sure that the air is going through a high-efficiency filter. 

Otherwise, any viral airborne particles will just be transmitted to another part of the building or an adjacent room.

When cold outdoor air with little moisture

is heated indoors, the airs relative

humidity drops to about 20%.

This dry air

provides a clear pathway for airborne

viruses, such as COVID-19.
