Will an Ozone Generator protect me and my family from COVID-19?
No, do not use ozone generators in occupied spaces. When used at concentrations that do not exceed public health standards, ozone applied to indoor air does not effectively remove viruses, bacteria, mold, or other biological pollutants. Visit the Centers for Disease Control and Prevention's website for best practices to protect…

Will an air cleaner or air purifier help protect me and my family from COVID-19 in my home?
When used properly, air purifiers can help reduce airborne contaminants including viruses in a home or confined space. However, by itself, a portable air cleaner is not enough to protect people from COVID-19. When used along with other best practices recommended by the Centers for Disease Control and Prevention, operating…

Can air cleaning devices that use bipolar ionization, including portable air cleaners and in-duct air cleaners used in HVAC systems, protect me from COVID-19?
Bipolar ionization (also called needlepoint bipolar ionization) is a technology that can be used in HVAC systems or portable air cleaners to generate positively and negatively charged particles. Provided manufacturers have data to demonstrate efficacy, manufacturers of these types of devices may market this technology to help remove viruses, including…

Where can professionals who manage school, office, and commercial buildings get information on ventilation and filtration to respond to COVID-19?
Professionals who operate school, office, and commercial buildings should consult the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) guidance for information on ventilation and filtration to help reduce risks from the virus that causes COVID-19. In general, increasing ventilation and filtration is usually appropriate; however, due to the…

Will running an evaporative cooler (sometimes known as a "swamp cooler") or whole-house fan help protect me and my family from COVID-19?
Both evaporative coolers (or "swamp coolers") and whole-house fans can help protect people indoors from airborne transmission of COVID-19 because they increase ventilation with outside air to cool indoor spaces. Evaporative coolers are used in dry climates. They use water to provide cooling and increase relative humidity indoors. When operating…

What is Upper-Room Ultraviolet Germicidal Irradiation (UVGI)? What is HVAC UVGI? Can either be used to disinfect the air and help protect myself from COVID?
A professionally designed system of ultraviolet germicidal irradiation (UVGI) that is well installed and maintained can effectively kill the virus that causes COVID-19 and help protect people from the disease indoors. Typically, UVGI systems are installed near a room ceiling (upper-room UVGI) or inside the HVAC system of a building…

How can I increase ventilation at home to help protect my family from COVID-19?
Ensuring proper ventilation with outside air is a standard best practice for improving indoor air quality. However, by itself, increasing ventilation is not enough to protect people from COVID-19. When used along with other best practices recommended by the Centers for Disease Control and Prevention, increasing ventilation can be part…

What kind of filter should I use in my home HVAC system to help protect my family from COVID-19?
Minimum Efficiency Reporting Values, or MERV, reports a filter's ability to capture particles. Filters with MERV-13 or higher ratings can trap smaller particles, including viruses. Many home HVAC systems will have a MERV-8 filter installed as the default. Upgrading to a MERV-13 rated filter, or the highest-rated filter that your…

Can I measure carbon dioxide (CO2) indoors to get information on ventilation?
Good ventilation is important to help protect people from COVID-19 and for healthy indoor environments in general. Carbon dioxide concentrations indoors can provide information about ventilation but need to be interpreted carefully. Additional Information: See CDC Ventilation FAQs for more information. See the ASHRAE Position Document on Indoor Carbon Dioxide…
