WHY WE ALL NEED MORE PROTECTION
THAN AN N95 OR N99 RESPIRATOR CAN PROVIDE
There are many problems with wearing a surgical mask, a scarf,
a cotton mask, an N95, or an N99 respirator.
THE INABILITY TO REMOVE VIRUSES
The first problem with all the masks relates to their inability to remove viruses (including Covid-19) from the air. Masks protect others from your coughs and sneezes but does little for you.
Scarfs provide minimal protection for you from COVID-19. They remove 50% or less of particles of 1 micron or larger but viruses are 1,000 times smaller.*1
Surgical or cotton masks at best remove about 79% of particles of 1 micron or larger.*1
N95 respirators are only 95% (N99 at 99%) effective for viral particles larger than .3 microns. With leakage, the effectiveness of the respirators is minimal due to leakage. For these larger particles, leakage can easily reduce their effectiveness to 85% for an N95 and 89% for an N99 respirator.*2
These combined affects significantly lower the effectiveness of the respirators or masks. At 85%, in a room that has COVID-19 in the air, the protection level is the same as if you remove your respirator for one breath every 30 seconds and take a full breath of infected air. strong>
POOR FIT EQUALS DRAMATIC LEAKAGE AND UP TO 20% FILTRATION LOSS
The second major problem with respirators is getting them to fit correctly on your face, with minimal leakage. Even with careful adjustment, recent studies show that leakage is often as high as 15%.
In addition, if you have even a single hair caught between your face and mask, you have just created a channel for the virus that is 1000 times bigger than the virus itself. This may increase the leakage well above 25%.
In contrast, when available, the HERO-1™ is expected to provide increased protection on the order of 99.99%. At this level of protection, you have to wait fifteen hours before you have effectively taken in one breathe of potentially infected air. The HERO-1™ is ecpected to almost eliminate leakage since it uses a positive pressure airflow mask system. This will be confirmed by an independent lab before product release.
EXCESSIVE HEAT AND DISCOMFORT CAUSES RESPIRATOR MISUSE
In addition to fit problems with respirators, excessive heat buildup and ensuing discomfort are serious problems when wearing a respirator like an N95 or N99. With every exhale, the wearer builds up heated air within their mask (an N99 is unbearable even for very short durations of even one minute).
After a few minutes, a person wearing the N95 mask will naturally react to the heat by either taking it off or cracking it to allow outside air in for cooling and relief.
In addition, recent studies show CO2 buildup of 2.5 to 3.5%*3 within an N95 respirator. That is a significant amount of CO2 for even a healthy person; causing potential dizziness, anxiety, and lightheadedness.
