Can Air Purifiers Prevent the Spread of COVID-19?
Air purifiers are a great asset for any home to enhance the air quality indoors. Those who have trouble with allergies can especially benefit from air purifiers as they filter out unwanted allergens and pollutants from the air. Apart from the air quality benefits of air purifiers, you're likely wondering if they can assist you during this time of pandemic to stay healthier and safer from the virus.
Understanding How COVID-19 Spreads
While there is still a lot of research going on regarding the subject, COVID-19 is thought to spread via droplets in the air. These droplets can be released when a person talks, sneezes, coughs or expels air in a similar way. We've all been instructed that these droplets can travel for up to six feet, which is why we're maintaining a social distance of such. Masks have been shown to be effective at preventing the transfer of these droplets.
How Can an Air Purifier Help?
When it comes to fighting COVID-19, air purifiers play two simple roles. First, they work to add more clean air to rooms in your home. This essentially dilutes the number of virus particles that are in an area of your home. This information has been verified in-hospital use situations. By running an air purifier, it will dilute the number of virus particles that are present and lower a person's risk of contracting the virus.
Second, air purifiers work to filter harmful pollutants from the air. HEPA filters are currently known for their ability to remove 99.97 percent of particles from the air. Much of this is things like allergens and pollen. However, it's thought that HEPA filters could be potentially helpful to remove the virus-infected droplets.
HEPA Filters and The Virus
HEPA filters trap airborne particles that are .3 microns or larger. The coronavirus is known to be .125 microns in diameter. At first glance, this reveals that the HEPA filter won't capture the virus-infected droplets. However, that's not the case. You have to think about how the virus travels.
While the virus is only .125 microns in diameter itself, it travels in droplets. These droplets are created when a person breathes, coughs, talks, and so forth. These droplets reign in at around 1 micron in diameter. So, with the virus traveling inside of these droplets, that means they're now big enough to get trapped by the HEPA filter.
