According to the WHO, airflow can help control infection rates of airborne diseases and this coronavirus is airborne. This means we can help create safer spaces and reduce the amount of virus around a sick person using airflow.
How does the air move in your home? When you open your front door, does the air move from the inside of your home-out or the outside-in? How often does the air in your home get refreshed?
In good weather, we can open our windows to achieve airflow but it is hard to control the direction of that air and breezes are notoriously inconsistent. Heating and air conditioning systems usually recirculate air around our homes but they don’t bring in fresh air. Bathroom exhaust fans and dryers move indoor air to the outside and that air is replaced by outside air being drawn into our homes via nooks and crannies.
As a result, having a small window fan in your home can direct air in the direction you need.
If you or someone you live with gets sick, putting a fan in their room to blow air out of the house will help prevent the virus from getting into the rest of your home.
If you live with an elderly person or someone at high risk, having a window fan blow outside air in will keep air from the rest of your home from flowing into their room and creates a safer space for them; especially if another family member becomes ill.
Window fans don’t have to be large to promote healthy air flow but we do suggest one made to fit into the window and create airflow in whichever direction you need.
