8 Best HEPA Air Purifiers for COVID (2023)

According to the EPA (Environmental Protection Agency), indoor air tends to be two to five times more polluted than outdoor air, since there is less ventilation and recirculation of air. This is where an air purifier can come in, to ensure that you can breathe easy, despite the additional pollution.

What Is a HEPA Filter and How Does It Work? High efficiency particulate air (HEPA) filter 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.

The US CDC says air purifiers can help “reduce the airborne concentration of the virus that causes Covid-19 (SARS-CoV-2), which can reduce the risk of transmission through the air.” However, the agency says that even regularly using an air purifier or portable air cleaner is “not enough to protect yourself and your family from Covid-19.”

The Environmental Protection Agency (EPA) also cautions that “by itself, air cleaning or filtration is not enough to protect people from exposure to the virus that causes COVID-19.”

Levoit HEPA Air Purifier Review
We have used this air purifier for about 6 months now, and we love it. The purifier really does clean up the air and makes it fresher. It helps when you are running the ac and takes out the nasty wet ac air that accumulates over time. When we had covid and felt congested, a few minutes after turning on the air purifier, it was much easier to breathe. If you need a purifier, this one’s great!

I ordered this purifier for my grandmother to have an extra layer of pandemic protection. She’s almost 90 and requires home health aides and some family support to continue living independently — so any additional precautions to protect her from COVID are welcomed.

An added benefit to purchasing this for her is that her oxygen levels have also increased by six percent! She feels the difference, doctors and nurses are pleased — and I’m ecstatic. Best investment of 2020.

I have allergies, and being home most of the time now with the COVID-19 stay at home order, I was struggling.

Shark HE601 HEPA Air Purifier Review
With all the fires going on around us here in Montana having clean air in our home was a top priority. We have open common area ( living room, kitchen, and dining room) so we needed one for a large area. Within an hour the air was at 100 %. Count us happy.

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 (indoor).
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


a. Is a HEPA Filter Washable?

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.
