Air purifiers have gained popularity over the past few months, riding on rapidly spreading coronavirus cases in the country and abroad. Air purifiers may be a certain way to shield oneself against the disease, especially when used in the right manner, accompanied by the right precautions.

This is why it would be prudent to look into stocks that will gain from the rise in demand for air purifiers.

According to a report by Research and Markets, the global air purifiers market is expected to reach $1.86 billion in 2023 at a CAGR of 6.13% from $1.55 billion this year after registering a CAGR of 20.74% from $1.29 billion in 2019.

The major factor driving the popularity of air purifiers is the rising concern for airborne diseases. Air purifiers can, to a large extent, help consumers who are suffering from asthma, airborne allergies and other breathing disorders. This is why most residential and commercial units invest in air purification equipment.

In fact, demand for air purifiers has gone up in the United States with the onset of the pandemic earlier this year. Coronavirus is primarily transmitted from an infected person to a healthy one through respiratory droplets and contact routes.

According to the United States Environmental Protection Agency, air purifiers can diminish airborne contaminants which comprise viruses in any confined space. However, one would still need to use it along with other best practices recommended by the Centers for Disease Control and Prevention for an ideal plan to protect oneself against the disease.

This is where high efficiency particulate air (HEPA) filters come in. According to Wirecutter, the virus responsible for COVID-19 is approximately 0.125 micron in diameter.The virus thus falls in the particle-size range that HEPA filters are more-than-capable of capturing (0.01 micron and above). A study of HEPA filtration by NASA also proves why these filters are most efficient.

Therefore, it comes as no surprise that as the number of new cases of the highly infectious disease rises, demand for HEPA filters by consumers for their personal use will witness an uptick.

To back the case of HEPA filters further, one may take a look at the Hong Kong Hospital Authority’s recommendation of using portable air purifiers with HEPA filters in hospitals during the SARS outbreak in 2003. The filters likely reduced transmission of the disease to healthcare workers in hospitals where isolation wards were unavailable.

In the United States, the CDC also recommended the use of these purifiers to lessen viral concentrations of the SARS virus when well-ventilated hospital rooms were occupied.
