How Do HEPA Air Purifiers Disinfect Germs Viruses And Smoke

In Covid-19's fight, products such as disinfectant sprays, face masks, and touchless garbage cans, are being pushed as essential. According to medical experts, one additional item that people should be adding to their arsenal is an air purifier. A good air purifier is not only helpful in eliminating airborne dust, pollen, smoke, and other irritants but can also keep dangerous germs and bacteria at bay. 

How Does an Air Purifier Work?

Air purifiers eliminate germs, dust, mites, pollen, and other potentially hazardous particles by drawing air into a chamber and passing it through a filter. The air is returned to your house once it has been cleansed by the air purifier.

The finest air purifiers can also absorb or filter out smells like those caused by cooking or smoking. A few air purifiers also have a heating or cooling option, allowing them to function as a stand-alone fan or heater when the weather changes.

What is a HEPA Air Purifier?

HEPA filters (high-efficiency particulate air) are used in the best air purifiers to collect more particles from the air.

A standard air purifier filter has a design and filtration ability similar to that of a coffee filter. These are among the most popular air filters in today's homes and offices. Despite being expensive and hard to locate a few decades ago, HEPA filter air purifiers are now used everywhere, from homes to automobiles, to planes to medical facilities.

True HEPA air purifiers capture 99.97% of particles as small as 0.3 microns, including allergens and odors. A HEPA-type filter, on the other hand, can catch 99% of particles 2 microns and larger, such as pet dander and dust. While these particles are too small to be seen with the naked eye, they are large enough to enter your lungs and cause problems.

The smaller the micron, the harder it is to filter out of the air. To put it into perspective the human eye can detect a particle that is approximately 10 microns. Bacteria can be as small as 0.3 microns, which is why 0.3 micron industrial HEPA filters are used in pharma companies


Can an Air Purifier Help With Viruses?

It's both a "yes and no" answer. According to the CDC (Centers For Disease Control And Prevention), these units can help “reduce the airborne concentration of the virus that causes, for example, Covid-19 (SARS-CoV-2), lowering the risk of transmission through the air.” 

HEPA filters will catch 99.97% of particles with a diameter of exactly 0.3 microns. Particles of that size are ideal for passing through the filter's fibers, but bigger and smaller particles collide with the structure as they flow through the air. 

Although the new coronavirus is 0.125 microns in diameter, the droplets it travels in - when individuals cough, talk, or breath - are initially bigger, approximately 1 micron in diameter. Experts say it's a size that HEPA filters can readily absorb.

Nonetheless, you still have to follow the usual precautions, such as washing your hands with soap and water, using hand sanitizer wearing a protective face mask when in close contact with others.
