Mask Education & Science Facts 

Scientists say this is the single most dangerous way that Covid-19 spreads.


(1) Estimated 75% of Coronavirus (SARS-CoV-2) cases come from AIRBORNE micro-droplet aerosols that can accumulate and linger in indoor air for hours. (2) 25% of cases come from droplets which travel 3 to 10 feet, with some cases coming from touch.

Stay safe. AAAR scientists estimate 75% of infections are spread through floating Covid-19 breath aerosols. Untested masks do not offer robust protection from indoor Coronavirus aerosols. Our masks do.

LINK: Staying six feet apart “offers little protection from pathogen-bearing aerosol droplets sufficiently small to be continuously mixed through an indoor space.”

CDC and FDA approved KN95 masks are specifically designed and tested to protect you by filtering out .012 viral aerosols with FDA and CDC Authorized 0.10 microns filtration respirators. No one can make claims or measure these kind of details absent precision fitration testing the whole mask.

Here is why the CDC and FDA rigorously test all our respirator facemasks.


The FDA and CDC under the Dept of Health and Human Services view all health providers as a US National Security resource. The Federal Government runs a gauntlet of tests to assure N95 respirator facemask safety for MDs and Health workers. Our K95 and KN95 respirator facemasks for the public formally likewise pass FDA and CDC >95% filtration standards.

Verified Indoor Protection from Floating Viral Aerosols.

  • Biopharmaca stays current with FDA and CDC listings of formally approved N95, K95, and KN95 masks.
  • We review CDC-NIOSH “Respirator Assessment Results”, including test-verified, approved masks.
  • We monitor FDA EUA (Emergency Use Authorization) for any facemasks which have lost or gained FDA EUA Authorization.
  • Biopharmaca cross-checks the entire system of FDA/CDC tests, re-tests and formal reviews to insure that our masks meet Quality Control as stated and are formally authorized for >95% filter approval.




The Filtration difference between our masks and cloth and refillable filter masks.


Our KN95 mask has a filtering ability down to, and actually below, the size of Covid-19. The coronavirus is about 0.12 microns in diameter and KN95 and N95 masks protect down to 0.1 microns, with 95+% efficiency.
