While #Ventilate2Educate is geared towards schools, we can #Educate2Ventilate with simple directives for small businesses & organizations. Simple low-cost changes can make for an enormous indoor air quality improvement. Low-rise small commercial buildings are everywhere.

These simple ventilation actions and more are described on the CDC's Ventilation in Buildings Page: cdc.gov/coronavirus/20…
Idea for a local Business Improvement Area #Educate2Ventilate campaign: Team up with a local HVAC contractor and visit all the storefronts with a CO2 meter to promote simple changes to improve indoor air quality. Add energy efficiency measures too.

Older small building without a ventilation system? Ensure exhaust fans are running, window is cracked open. Add portable HEPA filtration. Typical heat pump or A/C split systems do NOT introduce outdoor air and usually have a weak filter. #Educate2Ventilate
Upper-room UVGI can be cost effective compared to high ventilation rates for higher-risk settings: hospital waiting room, school nursing office, bars & cafeterias, break rooms, classrooms, shelters, gyms, other crowded settings without masks cdc.gov/coronavirus/20…
