How does ventilation help prevent the spread of COVID-19?

Improving ventilation is an important COVID-19 prevention strategy that can reduce the number of virus particles in the air. Along with other preventive strategies, including wearing a well-fitting, multi-layered mask, bringing fresh outdoor air into a building helps keep virus particles from concentrating inside.

How can I improve ventilation in my home during the COVID-19 pandemic?

• Operate a whole-house fan, or an evaporative cooler, if your home has one.• Operate a window air conditioner that has an outdoor air intake or vent, with the vent open (some window air conditioners do not have outside air intakes).

Can ceiling fans improve the circulation of air to reduce transmission of COVID-19?

The use of ceiling fans can improve the circulation of air from outside and avoid pockets of stagnant air forming indoors. However, it is critical to bring in air from outside when using ceiling fans, such as by opening windows.

Can fans be used safely inside during the COVID-19 pandemic?

Air blowing from an infected person directly at another person in a closed space increases the risk of the virus spreading from one person to another.If COVID-19 is circulating in your community and the use of a table or pedestal fan is unavoidable, it is important to regularly bring in air from outside by opening windows or doors, while minimizing how much air blows from one person (or group of people) to another person (or group of people).

Can HVAC systems reduce the spread of COVID-19 in indoor spaces?

Heating, ventilation and air-conditioning (HVAC) systems are used to maintain indoor air temperature and humidity at healthy and comfortable levels. A well-maintained and operated system can reduce the spread of COVID-19 in indoor spaces by increasing the rate of air change, reducing air recirculation and increasing the amount of outdoor air coming in. Settings that recirculate the air should not be used. HVAC systems should always be regularly inspected, maintained, and cleaned.

Can COVID-19 spread through HVAC systems?

While airflows within a particular space may help spread disease among people in that space, there is no definitive evidence to date that viable virus has been transmitted through an HVAC system to result in disease transmission to people in other spaces served by the same system.

What are the recommendations for reducing the indoor concentrations of covid-19 virus?

For COVID-19, the first steps in reducing the indoor concentrations of the virus are wearing face masks, physical distancing, and reducing occupancy levels. Improved ventilation is an additional prevention strategy.

Why is proper ventilation important for your home?

Proper ventilation keeps the air fresh and healthy indoors. Like the lungs, homes need to be able to breathe to make sure that fresh air comes in and dirty air goes out. Air indoors can build up high levels of moisture, odors, gases, dust, and other air pollutants.

How does a dvele fresh air ventilation system work?

Each Dvele home’s fresh air ventilation system provides a continuous circulation of air that is constantly filtered. Air is drawn in from the top of each room, cleaned, then moved through the bottom vents. This constant movement keeps the air fresh and safe.

What happens if there is no ventilation in a house?

Without mechanical ventilation to provide fresh air, moisture, odors, and other pollutants can build up inside a home. Mechanical ventilation systems circulate fresh air using ducts and fans, rather than relying on airflow through small holes or cracks in a home’s walls, roof, or windows.

Does fresh air ventilation make a house healthier?

In fact, because fresh air ventilation systems reduce the consumption of energy in addition to making a house healthier, they often come standard in energy-efficient homes. Manufacturers of modern prefabricated houses, like the team at Dvele, exemplify the strides being made to standardize healthier homes.
