As Covid-19 cases continue to rise due to the supertransmissible variant of Omicron, it is important to take all necessary precautions to stay safe. One way to do this is by using air purifiers to filter out airborne bacteria, including the SARS-CoV-2 virus that causes Covid-19. When looking for the best air purifiers for viruses, it is important to look for one that includes a high-efficiency particulate air (HEPA) filter. These filters can capture at least 99.97 percent of particles as small as 0.3 microns, including most airborne pathogens. The Centers for Disease Control and Prevention (CDC) states that HEPA filters are the most effective in the market at trapping particles that people breathe out when breathing, talking, singing, coughing and sneezing.
The EnviroKlenz air cartridge is an effective way to capture and filter pathogens similar in size to coronavirus, especially with airborne transmission as the main form of Covid-19 infection. It has a three-stage filtration process that uses a HEPA filter to remove 99.97 percent of airborne allergens as small as 0.3 microns, a pre-filter for large particles and a carbon filter for odors. The Winix 5500-2 air purifier has a four-stage filtration system that uses a HEPA filter, pre-filter, carbon filter and plasma filter. The company claims that its “PlasmaWave” technology safely removes pollutants without any harmful ozone.
It is also 99.95% efficient at removing particles down to 0.1 microns and 99.97 percent particles down to 0.3 microns. The Dyson Purifier Cool TP09 is an air purifier and cooling fan in one device. 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, as well as a sensor that detects and removes formaldehyde from carpets and carpets. It also has additional intelligent capabilities such as hands-free voice control and in-app air quality monitoring. The Blue Pure 311 Auto air purifier has a combination of filters that make it remarkably quiet, cleaning the air with a sound level equivalent to a gentle whisper (23-53 dB).
It also has an automatic mode that can be adjusted to real-time conditions in any space based on a particle sensor. The Winix 5500-2 is the best air purifier we've ever tested for filtering Covid-19 particles. It uses a true HEPA filter, carbon filter and plasma filter, and performed incredibly well in our odor tests, eliminating virtually any trace of cinnamon and smoke. It also has useful features such as sleep mode, a timer, and several status lights. For portable HEPA filter units equipped with locally controlled ventilation ducts are required for filtering coronavirus. Before making any changes to the air filter of an HVAC system, users should consult their HVAC manual or an HVAC professional. In conclusion, when looking for an air purifier to combat the airborne spread of Covid-19, it is important to look for one with a HEPA filter that can capture at least 99.97 percent of particles as small as 0.3 microns, including most airborne pathogens.
