Use fans to make the air flow better. Put a fan as close as you can to an open window that is being blown out. You can help get rid of germs in your home by blowing air outside. Fans can help with air flow even if the windows are closed.
You don’t have to do what I say if you want to make the air cleaner. If you don’t have the money to put vents in your windows, just open as many windows as you can. To make gradients, open the doors between rooms with only one window. Even if the air conditioner or heater is on, you should still do this. Yes, it saves power, but even a small crack in a window slowly brings in fresh air. Because two windows are broken, the air can better figure out where to go. The air quality in a single-vent chamber can be improved by using a HEPA filter, which has been shown to be effective at reducing dangerous aerosols.
Ventilation with clean outdoor air is better for your health because it gets rid of viruses, other particles, and gases like the carbon dioxide that everyone breathes out. Most ventilation systems use some recirculated air because it is hard to heat or cool air from the outside.
People spend more time inside during the winter, and windows are often too cold to be left open. This makes it easier for viruses to spread through the air. During the winter, especially in heated rooms, the air is drier. Dry air hurts the linings of the airways, which makes it easier for viruses to get into the airways. Aerosols that are small will also stay in the air longer. Because of this, COVID-19 airborne transmission is likely to go up during the winter.
If you want to improve ventilation even more, you could open doors or windows and use fans inside as well. A window can have both specialized window fans and box fans or tower fans. Fans can push air out of a window by being turned away from it or toward it (blowing air into the room).
SARS-CoV-2, the virus that causes COVID-19, and other airborne contaminants can be reduced by letting in enough fresh air. But just increasing ventilation is not enough to keep people from coming into contact with the COVID-19 virus. Increasing ventilation can be part of a plan to protect yourself and your family, along with other best practices like keeping people physically apart and staying away from crowded places inside, wearing masks, and washing your hands.
