Consider talking to an HVAC professional for help and more information.

Consider lower levels of relative humidity in winter to stop too much moisture from forming on windows and other surfaces.

Try to keep the indoor relative humidity between 40% and 60% in spring and fall.

Limit the number of people in a space to a number that allows at least 50 square feet per person.

Consider using rooms with high ceilings that have more space for anything in the air to move around and thin out.

Bring in fresh outdoor air as much as possible.

Be careful about using unproven technologies. State agencies do not generally provide HVAC consultation or inspection. Note: Things to consider about indoor air that are listed below may cost anywhere from nothing to thousands of dollars, and may take a little or a lot of work. Managing indoor air will not stop the spread of COVID-19 by itself, but it can lower the number of people infected when people also wear a face covering stay at least 6 feet from others who are not household members have good hand hygiene clean and disinfect surfaces that are touched a lot and take any other steps to control and stop infection. Indoors, there is less airflow to move around and spread out than there is outdoors. Someone else can breathe in these droplets, or the droplets can land on someoneвЂ™s eyes, nose, or mouth and cause infection. Droplets from someone who has COVID-19 can contain the virus. Tiny droplets form in the air when someone coughs, talks, sings, or laughs. Tents are defined as having two or more sides enclosed.Д¬OVID-19 is spread mainly between people who are within about 6 feet of each other for at least 15 minutes. Note that the indoor air considerations in this document also apply to tents set up for events or businesses. Buildings with complex heating, ventilation, and air conditioning (HVAC) systems will typically need to work with HVAC professionals to evaluate and/or improve the ventilation, and health care facilities have their own ventilation standards. The information below is for general audiences who may have questions about air in buildings and COVID-19. As we learn more about COVID-19, recommendations and guidance are updated frequently.
