With Covid-19 cases on the rise due to the highly transmissible variant of Omicron, you are likely doing everything you can to stay safe, which means staying home a little longer than usual. If you're looking for an easy way to make your work from home office more comfortable, or breathe a little easier in the tight spaces of your shared home, air purifiers are the ideal solution. They can also help when it comes to viral circulation in the air indoors. 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.
These filters can capture at least 99.97 percent of particles as small as 0.3 microns, including most airborne pathogens. The CDC says they 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 could be 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. The Winix 5500-2 is an inexhaustible source of filtration, and while it may not have the “smartest” bells and whistles, its unique method of breaking down odors, allergens and other pollutants makes it an excellent choice. It has a four-stage filtration system that uses a HEPA filter (recommended for filtering particles such as Covid-1 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, plus a filter of plasma.
The Dyson Purifier Cool TP09 isn't just a regular air purifier, it's a cool air purifier that works as a cooling fan when not working overtime as an expertly designed bacteria killer. 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 additional intelligent capabilities, such as hands-free voice control and in-app air quality monitoring. The Blue Pure 311 Auto is exceptionally quiet with a sound level equivalent to a gentle whisper (23-53 dB).
It has a combination of filters that makes it remarkably quiet, cleaning the air with a sound level equivalent to a gentle whisper (23-53 dB). You'll also get all the power of a superior air purifier in a single energy-saving package, operating up to 40 percent more efficiently than standard models. To filter coronavirus, portable HEPA filter units equipped with locally controlled ventilation ducts are required. When properly equipped, these portable or “stand-alone” filter systems can be used to direct the virus path away from people sitting in an enclosed area.
In 2003, during the SARS outbreak, the Hong Kong Hospital Authority recommended that hospitals use portable air purifiers with HEPA filters to help reduce transmission to healthcare workers if isolation rooms were not available. But you'll also wonder if an air purifier can prevent COVID-19 by capturing virus particles that might be traveling through the air. Portable air cleaners are an option to increase ventilation systems, but they often cost hundreds of dollars, putting them out of reach for schools and other public spaces facing budget constraints. Wearing masks without air filters reduced receiver aerosol exposure by 72%, and wearing air filters without masks reduced exposure by up to 65%. Using an air purifier at home can be a good idea at any time, to help filter indoor allergens and contaminants, such as fumes from kitchen and cleaning.
