A CO2 monitor (around $100 online) can help give a clue to if there is enough ventilation. CO2 levels outdoors are just above 400 ppm. A well ventilated room will have around 800 ppm. Any higher than that is a sign the room needs more ventilation (2/6)
Since the #coronavirus is spread through the air, higher CO2 levels means there is a higher chance of transmission if an infected person is inside. @ShellyMBoulder recommends keeping the CO2 levels below 600 ppm (3/6)
There are 2 options to make an inside space safer: bring in air from outside or remove the virus from the inside air.
Many buildings, like schools, do not meet recommended ventilation rates, so keep windows and doors open. A box fan in a window blowing out can help too (4/6)

The safest indoor space is one that constantly has lots of outside air replacing the stale air inside. And in any room, the more people inside, the faster the air should be replaced (5/6)
If you walk into a building and it feels hot, stuffy and crowded, chances are there is not enough ventilation. Turn around and leave.
