Can Air Purifiers Prevent the Spread of COVID-19?
Having an air purifier in your home or office is a great way to improve indoor air quality. When you breathe in unhealthy air, you may see an increase in illness, asthma attacks, or allergies. Depending on what type of air purifier you get, you can typically filter out things like pet dander, pollen, mold spores, and even viruses.
With so many people stuck at home because of the COVID-19 pandemic, indoor air quality is more important than ever. If you don’t already have a unit, you may be wondering if investing in a purifier will help prevent the spread of COVID-19. Let’s take a closer look at this topic.
The Spread of COVID-19
When you’re in an enclosed space, COVID-19 can spread through small droplets from your body. This can occur from coughing, talking, and even breathing. The majority of these droplets are heavy enough that they immediately fall to the ground. In other cases, these droplets can remain suspended in the air for an extended period of time. You can open up some windows to dilute the contaminants in a given room, but a purifier provides a method of purification when the weather may not allow your windows to be flung open.
There is still a lot to learn about the Coronavirus. Long after we’ve gotten back to our normal lives, scientists want to figure out what makes this virus thrive. What we do know is COVID-19 acts similarly to viruses like SARS. Air purifiers with a HEPA filter have been effective in removing SARS droplets from the air. The CDC recommended using these air purifiers to prevent the spread when the outbreak was occurring in the early 2000s.
How it Works
HEPA filters can capture as much as 99.97 percent of germs that are about 0.3 microns in diameter. The Coronavirus is 0.125 microns in size. Keep in mind, the droplets must be circulating through a room properly for them to reach the purifier. Proper airflow in a room with a purifier is ideal.
While all purifiers aren’t going to prevent the spread of COVID-19, it’s worth investing in a unit that can remove the smallest particles and germs from the air that you’re breathing indoors. If you have someone at home who is currently showing signs of illness, you can try running the purifier in that specific room. It may cut down on the number of germs that are circulating in the rest of your home. For more information, contact us at Harwich Port Heating and Cooling today!
