Comment: Do home window air conditioners suck in outside air or do they recirculate existing room air? I know that hot exhaust air blows out. We have neighbors that sit outside and smoke cigarettes and I'm concerned about what might be brought inside, along with cooler air, by the air conditioner. Thank you!

Comment: Dr. Allen,
You are a rare voice expressing concern for airborne transmission while leading authorities are expressing otherwise. I am a regulator currently evaluating a request for emergency exemption to pesticide registration for a product that claims to disinfect the air. Expressed opinions of leading authorities such as the CDC and WHO would lead me to decline this request. I ask for your opinion of the value of adding a disinfectant to the air (assuming EPA could confirm efficacy and safety) knowing the availability of such a product, unlikely as it would be to interrupt the droplet transmissions, might also lead to less focus or care with known effective interventions (masks, distancing, maximized fresh air in buildings). This is a fairly urgent request and I welcome your thoughts. Thank you.
