Although more than a year has passed since the world began dealing with the corona epidemic, this is the first time the CDC has made a specific recommendation regarding indoor space ventilation.
In the past, this issue was mentioned in the guidelines published by the center, but now it has devoted an entire page to this issue and its importance - especially for schools, in the new guidelines.

"If this is possible from a safety point of view, open the door and windows. Even opening the window to a narrow slit can improve the flow of air entering the room from the outside and reduce the potential concentration of virus particles in the air. If the room temperature becomes too cold or too hot, try adjusting The same with the help of the thermostat of the air conditioning system ", reads the new directive.
In addition, the CDC recommends using fans to increase the effectiveness of opening windows to improve circulation.
The fans can help push polluted air out of the room, and draw clean air from the outside into it, through the open windows and doors.

In addition, the guidelines also refer to the operation of air conditioning systems, which are particularly relevant for U.S. states where particularly low winter temperatures prevail during these months. Set air conditioning systems so that as much outside air as possible enters the building. Greater outdoor airflow mixes air composition inside The spaces and also passes the recycled air through the filters of the system more frequently. "
The guidelines also recommend the installation of air purification systems and ultraviolet light lamps, especially in spaces that are more prone to infection, such as examination rooms in clinics, day care centers and schools.
However, the center's experts stress asked the public to fall into the trap of marketers of filters and various air purification gimmicks whose effectiveness has not been proven.
According to them, if one chooses to install any purifying systems, one should make sure that it is a system that has proof of its effectiveness and that it should be installed properly and professionally.
Beyond that, emphasize again - the most effective thing is fresh air.
