As the above table shows, an air purifier must remove exceedingly small particles. What can't be removed must be degraded or destroyed.
The HEPA Only Problem:
True HEPA is H13 or higher. Do not consider HEPA air purifiers that are less than H13 or do not state their value. True HEPA traps 99.97% of particles down to 0.3 microns in size and 99.95% at 0.1 microns. That's amazing engineering by itself! Virus particles, such a coronavirus, expelled by an infected human are around 1 micron. One micron is larger than virus particles themselves because they are always encapsulated by microscopic mucus materials of the host. A naked virus particle is not found in the environment, nor would it be able to survive on its own. However, there is a problem with relying on a HEPA only solution.
False Sense of Security:
Intuitively, True HEPA only air purifiers present as an effective means of reducing the risk of airborne transmissible infections. However, consider being in a room with one or more people infected with Covid-19. These people eject infectious pathogens into the air by talking, laughing, singing, yelling, coughing, sneezing, or simply breathing. Just a few moments of exposure to infected individuals puts you and other healthy people at risk. A True HEPA system with a high CADR will help mitigate this risk, to a certain extent. This may give you a false sense of security.
Here's the Problem:
A single sneeze from an infected person could contain as many as 200 million virus particles. Add that to the other carriers talking, laughing, singing, yelling, coughing, sneezing, and breathing. Now, there are billions of particles in the air! There could be 50 billion airborne virus particles in the air after mere minutes. If a True HEPA air purifier could instantaneously remove 99.97% of those pathogens, 15 million would remain circulating in the air. Of course, air purification occurs over time, and not instantaneously, and therefore an air purifier with a high CADR is critical. But that un-trapped 0.03% can be deadly and therein lies the problem.
Deadly Problem Solved:
What happens to those millions of potentially lethal particles floating around that the HEPA purifier did not trap? The solution used by hospitals and other similar sterile environments is to kill the remaining pathogens inside the purifier as they pass through the HEPA stage. That is why the HEPA only solution could be deadly. VironAire has a True HEPA filter. However, this is the VironAire difference: The 0.03% of infectious contaminants not trapped by its HEPA stage is subjected to high-power UV-C 254nm ultraviolent light, photocatalysis, and a massive amount of negative ions. No other air purifier currently available can match the air purification and sterilization capabilities of VironAire.
VironAire Systems are Unique:
This is the first time that this level of medical-grade air purification has been made available to businesses and homes. In addition to True HEPA (H13), UV-C ultraviolent, a photocatalyst, and negative ion generation, VironAire also incorporates activated carbon, cold catalyst, and molecular sieve technologies. This is all in a portable and affordable unit. VironAire uses the same technological strategies used in large surgical centers and at NASA for sterilization.
And the Rest of the Story:
We focused on deadly pathogens above, but let's not overlook the rest of the story. VironAire also effectively and efficiently removes TVOC's, VOC's, such as formaldehyde, mold, dust mites, pollen, smoke, pet dander, PM2.5 particulate matter, noxious smells, allergens, and many other airborne contaminants. VironAire is truly your high-tech surgical mask!
The iVA1000 and iVA2500:
VironAire's iVA1000 and iVA2500 have a CADR (Clean Air Delivery Rate) of 582 and 910 respectively. CADR measures an air purifier's effectiveness based on the volume of clean air produced per unit of time. VironAire's high CADR values demonstrate an unprecedented effectiveness in purifying even large spaces: Read more in FAQs
