Can Air Purifiers Help Protect Your Home Against Coronavirus?

A quality air purifier can help filter out allergens and pollutants in your home that are generated from dust, cleaning products, and cooking fumes.

Now that we live in the age of coronavirus, the cleanliness of your indoor space is even more important, since you and your family are spending so much time at home under the country-wide ‘shelter-in-place’ orders.

So you may be asking yourself: is an air purifier effective in preventing the transmission of coronavirus? Can an air purifier capture virus particles that travel in the air and prevent them from being inhaled by you and your family?

The answer is that there are circumstances in which an air purifier can help reduce concentrations of virus particles in the room and thus reduce the potential for exposure and transmission. The average home air purifier should not be expected to “decontaminate” a room to the level needed for coronavirus, but air purifiers can be part of your approach to sanitizing your home against coronavirus.

Coronavirus is understood to be transmitted via droplets expelled from the body via coughing, talking, and breathing. Most droplets end up on the ground, but some research suggests that smaller particles may remain in the air for longer. One solution to improve the air quality in your home is to simply open up the windows to let in fresh air; this helps dilute indoor contaminants, including virus particles. If airing out the room isn’t an option, you may want to consider buying an air purifier.

First things first, if someone in your household has been exposed to coronavirus and is exhibiting symptoms of COVID-19, you should quarantine them in one area of the house. In addition to these steps to care for the infected person, you may find that running a high-efficiency particulate air (HEPA) air purifier in the room that they are quarantined in may provide a level of protection for other members of the household and caregivers.

Experiments done by Consumer Reports suggest that HEPA filters are very effective, and they are certified to capture 99.97 percent of particles that are precisely 0.3 micron in diameter. The novel coronavirus itself is 0.125 microns, but the droplets it travels in—when people cough, talk, or breathe—initially are larger, around 1 micron, which is a size that is easily captured by HEPA filters.

In conclusion, HEPA air purifiers, in conjunction with diligently cleaning surfaces in your home and washing your hands frequently, can help remove the coronavirus from your space.
