Best HEPA Air Purifier for Covid 2022

What is a HEPA filter and how does it work?

High efficiency particulate (HEPA) is a type of pleated mechanical air filter. This air filter can potentially eliminate 99.97 percent of dust, pollen, mold, bacteria, and any other airborne particles.

You can use HEPA filters for cleaning devices, air filters, portable air cleaners, whole-home fan systems, heating and cooling units, and more. The purpose is to remove microscopic particles from the air as it flows through these filters.

What is the difference between a HEPA purifier and regular purifier?

The difference between a HEPA filter and a regular filter is that HEPA filters are constructed of thin glass fibers and activated carbon-based materials. Whereas, porous materials such as cotton paper sheets and polyester are used in regular filters.

Can HEPA filters filter Covid?

COVID-19 virus approximately has a diameter of 0.125 micron (125 nanometers). Many media wrongly state that HEPA filters do not filter below 0.3 micron, and so cannot capture airborne coronaviruses. That’s incorrect.

HEPA filters are most efficient at catching ultrafine particles below the 0.3-micron HEPA test standard—almost 100 percent at 0.01 micron. Therefore HEPA filtration can capture airborne corona virus.

How to choose HEPA air purifiers

1. Size

Look for an air purifier that fits the size of the room you want to use it in. In general, your filter’s clean air delivery rate (CADR) score should be roughly two-thirds of the space in the room.


2. Ozone-producing air purifiers should be avoided.

Ozone is a gas that is produced during several types of air purification. While ozone gas is used to clean and disinfect the air, but it is also a pollutant that can irritate and may harm the lungs if inhaled. Ozone air purifiers are typically used in rooms that are unoccupied at the time of use. In the United States, no government agency has approved the use of ozone generators as air purifiers in houses.


3. When buying a filter, make sure it meets one of the following requirements:

– designated HEPA filter 

– CADR rated

– the product filters most particles smaller than 1 micron

Cleaning a washable HEPA filter with cold water only is recommended. However, you should not use water if you have a HEPA filter that is labelled as permanent. Only a vacuum hose or brush should be used to clean permanent HEPA filters.
