When used correctly, air purifiers can help reduce pollutants in the air, including viruses, in the home or in confined spaces. However, on its own, a portable air purifier is not enough to protect people from COVID-19. The best air purifiers can go a long way in removing and removing dangerous germs and bacteria found in the air from the air. Air purifiers were most effective when located in the center of the room, close to the aerosol source. These findings suggest that the use of portable HEPA air filters and universal masking may reduce exposure to simulated SARS-CoV-2 aerosols indoors, and that greater reductions occur when air filters and masking are used together.
In the general room, the team found SARS-CoV-2 particles in the air when the filter was turned off, but not when it was turned on. If you choose to use a device that incorporates bipolar ionization technology, the EPA recommends using a device that meets the certification of UL 2998 (Environmental Claims Validation Procedure (ECVP) for Zero Ozone Emissions from Air Cleaners). The combination of the two HEPA air filters and universal masking reduced total exposure by up to 90%. Portable HEPA air purifiers can reduce exposure to simulated SARS-CoV-2 aerosols indoors, especially when combined with universal masking.
But if someone in your household has COVID-19 or needs to quarantine until you can be sure they don't, it might make sense to have an air purifier in your room with the door closed, if only to help protect caregivers from possible exposure. No two air purifiers are the same, but one of the most important things to look for in the best air purifiers for viruses is the inclusion of a high-efficiency particulate air (HEPA) filter. When used in concentrations that do not exceed public health standards, ozone applied to indoor air does not effectively eliminate viruses, bacteria, mold, or other biological contaminants. These findings support the usefulness of portable HEPA air filters and universal masking in reducing exposure to indoor aerosols containing SARS-CoV-2.People with asthma or other respiratory problems can be very sensitive to air quality, so they should limit their exposure to ozone by staying indoors for days or avoid strenuous exertion while outdoors.
The filters are designed to improve indoor air quality by physically removing small particles of matter that may be floating, such as dust, pollen and pet dander. The air purifier will also be compatible with Google Assistant and Amazon Alexa, and an energy-saving air quality monitor adjusts the fan speed to match the air quality in the room. While the study provides useful information on the dynamics of respiratory aerosol particles and the effects of HEPA air filters and universal masking, many other factors are also important for disease transmission, including the amount of virus in the particles, the length of time the virus survives in the air and vaccination status of the occupants of the room. Choosing where in your home to place a portable air purifier to help protect yourself from airborne infections depends on the situation.
