Air purifiers do not kill viruses, including COVID-19. The most effective way to clean the air is to use a HEPA air purifier, which can remove 99.97% of airborne particles as small as 0.3 microns.

However, while HEPA air purifiers can remove a majority of the particles in the air, they are not 100% effective. Additionally, air purifiers only work if they are properly maintained and the filter is replaced regularly.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It was first identified in December 2019 in Wuhan, China. The World Health Organization declared the outbreak a Public Health Emergency of International Concern on 30 January 2020, and a pandemic on 11 March 2020. As of 3 April 2021, more than 132 million cases have been reported in more than 190 countries, resulting in more than 2.9 million deaths.

COVID-19 is primarily spread between people in close contact (within about 6 feet, or 2 meters) via respiratory droplets, such as when an infected person coughs, sneezes, or talks. These droplets can land in the mouths or noses of people who are nearby or be inhaled into the lungs. It’s also possible, though less common, for people to get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or eyes.

COVID-19 is primarily spread through respiratory droplets, which are larger than the particles that HEPA air purifiers can remove. However, if someone with COVID-19 is in the same room as an air purifier, it can help reduce the amount of respiratory droplets in the air and potentially reduce the spread of the virus.

An Air Purifier Can Help Make Your Air Cleaner

There is still a lot unknown about the coronavirus and how it affects people. However, it is clear that people with COVID can experience a range of symptoms. These can include fever, cough, and shortness of breath. Some people may also experience more severe symptoms such as pneumonia. In some cases, people with COVID may not show any symptoms at all. This is one of the reasons why the virus has been so difficult to contain. Even people who seem healthy can be carriers of the virus and can spread it to others.

In summary, air purifiers cannot kill COVID-19, but they can help reduce the amount of respiratory droplets in the air, which may help reduce the spread of the virus.
