What Air Filters Work Best for Covid-19?

With Covid-19 cases on the rise due to the highly transmissible Omicron variant, it's important to take extra precautions to stay safe. One way to do this is by investing in an air purifier. Air purifiers can help filter out airborne bacteria, allergens, and other pollutants, including particles of the SARS-CoV-2 virus that causes Covid-19. When shopping for an air purifier, look for one with a high-efficiency particulate air (HEPA) filter. These filters are the most effective at trapping particles that people breathe out when talking, singing, coughing, and sneezing.

The HEPA filter should be able to capture at least 99.97 percent of particles as small as 0.3 microns, including most airborne pathogens. The EnviroKlenz air cartridge is one such filter that claims to be able to capture up to 99.999 percent nanometer size particles down to 0.001 microns. It has a three-stage filtration process that includes a HEPA filter, pre-filter for large particles, and a carbon filter for odors. It also has a unique “PlasmaWave” technology that safely removes pollutants without any harmful ozone.

The Winix 5500-2 is another great option with a four-stage filtration system that includes a HEPA filter and pre-filter for large particles. It also has a carbon filter for odors and a “PlasmaWave” technology that safely removes pollutants without any harmful ozone. The Dyson Purifier Cool TP09 is an excellent choice if you're looking for something with additional features. It has a H13 HEPA filter that is 99.95% efficient at removing particles down to 0.1 microns and 99.97 percent particles down to 0.3 microns.

It also has a sensor that detects and removes formaldehyde from carpets and carpets, as well as hands-free voice control and in-app air quality monitoring capabilities. The Blue Pure 311 Auto is another great option for medium-sized rooms like bedrooms or living rooms. It has a three-stage filtration system with a HEPA filter that can remove 99.97 percent of airborne allergens as small as 0.3 microns, as well as a pre-filter for large particles and a carbon filter for odors. It operates up to 40 percent more efficiently than standard models and has an intuitive automatic mode based on a particle sensor.

Finally, the Alen BreatheSmart Classic is an air purifier made for large rooms but can also work quickly in small rooms like bedrooms. It has a HEPA filter that captures dust, allergens, pet dander, and other microorganisms, as well as toxic and harmful chemicals and odors from the air.
