Can the air purifier resist the new crown virus and protect the health of my family?


During the COVID-19 pandemic, people are worried about how to protect themselves from the virus. Studies have shown that wearing masks correctly and maintaining good social distancing can significantly reduce the spread of coronavirus (COVID-19) through droplets. But concerns about the possible spread of aerosols have also led many people to consider using air purifiers.

An excellent air purifier can indeed improve your life-reduce allergens such as pollen, mold spores, mites, etc., and effectively capture particles that are the same size (and much smaller) than the virus that causes COVID-19 to prevent wildfire smoke and other Kinds of smoke. However, to achieve these, you must have a powerful enough air purifier that can purify a large area of indoor air, such as a large living room, office, etc.; it must be quiet and must not affect sleep; and it is easy to operate and easy to replace the filter element.

Capture viruses in indoor air

The COVID-19 pandemic has had a major impact on global health. According to statistics, in 2020 alone, more than 50 million people were exposed to the virus, and more than 1.5 million people died from related respiratory complications, and it is still spreading globally, and some countries are still out of control.

So can the air purifier resist viruses such as COVID-19? First understand how the air purifier works and how the virus (especially COVID-19) spreads. Then, you can assess whether the air purifier helps protect you from viruses in the air.

The working principle of air purifier filter

Mechanical air purifiers use filters to trap airborne particles through a mesh filter usually woven from glass or special synthetic fibers. High efficiency particulate air (HEPA) and HyperHEPA filters are mechanical air purification filters. Mechanical filtration is the safest and most effective method to remove suspended particles in the air.

The diameter of the COVID-19 virus is approximately 0.125 microns (125 nanometers). It falls within the particle size range captured by the HEPA filter with extraordinary efficiency: 0.01 microns (10 nanometers) and above. Many media erroneously stated that HEPA filters cannot filter particles below 0.3 microns and therefore cannot capture airborne coronaviruses. That is wrong. NASA’s research on HEPA filtration is very technical, but the chart on page 7 and the previous paragraph explain well why HEPA filters are actually the most effective—almost 100% at 0.01 micron—at capturing 0.3 HEPA testing standards for ultrafine particles below micrometers.

Therefore, an air purifier with a hepa filter can remove viruses in the air, including the currently popular COVID-19 virus.

Clear wildfire smoke

As more serious fires become the new normal, even those who are not directly threatened are worried about how to deal with the spread of wildfire smoke. Two good news: According to the EPA, “If you are healthy, you usually don’t face a major risk from short-term exposure to smoke.” Second, there are some simple and effective ways to eliminate wildfire smoke in your home.

Keeping the air in your home clean during the fire season requires a multi-pronged approach. Buying a dedicated air purifier for your central air conditioner or buying a new filter is the most effective thing you can do to help protect the people in your home.

According to the U.S. Environmental Protection Agency (PDF), wildfire smoke is mainly composed of fine particles in the range of 0.4 to 0.7 microns. Real HEPA air filters are very good at removing particles of this size from the air.
