HEPA Filtered Solutions for Coronavirus

July 04, 2020



As the Coronavirus (COVID-19) has made its way across the world, it has become imperative to find different solutions to help prevent the spread of the virus in any capacity available. 


What is Coronavirus?


Coronavirus is a virus that comes in multiple forms that have been identified as several different strands, and different symptoms caused due to the virus. While researchers are still scrambling to find answers to educate the public, the general consesus has been hypothsized that the virus attacks the respiratory system and has an incubation period of 14 days from date of contact.


How Coronavirus is Transmitted


The Coronavirus (COVID-19) is a specific virus that directly attacks the respiratory system which spreads primarily by attaching to discharge generated from an infected person's saliva, cough, or sneeze. Additionally, it can be found on surfaces that have become infected if not properly cleaned or wiped down, as well as moisturized environments of air, if not properly filtered. Nonetheless, while research is still being done on COVID-19, the CDC and WHO has determined that this virus is not airborne, but spread by person-to-person contact through discharge from an infected person.


What are the symptoms of coronavirus (COVID-19)


Coronavirus (COVID-19) symptoms include:

Cough (Dry)

Shortness of Breath

Sore or "Achy" Muscles

Sore Throat

Temporary Loss of Taste and/or Smell

In some cases, coronavirus COVID-19 can lead to severe respiratory problems, kidney failure or death.

Does a Hepa Filter work against Coronavirus?

In short form, yes, it can, however, it is important to remember that the coronavirus is not a stand-alone, "floating-in-thin-air" virus, but it must be attached to something (ie water droplets, bacteria, dust). So, to answer that question more specifically, a HEPA filter tests up to 99.97% efficiency on particles down to 0.3 microns in size, and have the capability to filter down to 0.01 micron at a still extraordinary, yet lesser efficiency. The Coronavirus (COVID-19) falls in between 0.06 micron (60 nanometers) and 0.14 micron (140 nanometers) in diameter. In a 2016-study by NASA, it was tested and proven that HEPA filters were most efficient (almost 100%) at filtering particles at 0.01 micron, below the normal 0.3 test standard for HEPA filters.


It is not the position to use an air filtration system as the first line of defense against COVID-19, rather it should be utilized as a secondary engineering control to protect the environment in which work is being done.
