@BizzMac2 @CTVNews Low humidity causes viral containing droplets to evaporate and stay in the air longer. Most viral particals are bound within larger dropplets because of the much larger volume of fluid. https://t.co/suqrGCv8yT
@JudyandHuahua As part of ventilation we should include humanity control because at lower humanity dropplets evaporate faster and consequently stay longer in the air. https://t.co/suqrGCv8yT
@CovidDataReport @AshishKJha46 If we are trying to reduce transmission by improving air quality then lets not forget the importance of a humidifier. Low humidity causes droplet evaporation which increases the time that the droplets spend in the air. https
