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

(1) The majority Coronavirus (SARS-CoV-2) cases come from AIRBORNE micro-droplet aerosols that can accumulate and linger in indoor air for hours. Most masks will not protect you. (2) Estimated 25% of cases come from droplets which travel 3 to 10 feet, with some cases coming from touch. The majority of Covid-19 cases come from floating indoor viral plumes in indoor environments

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. All our masks are FDA Test-Certified high-filtration masks for serious protection from floating Covid-19 aerosols in indoor environments.

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 Scientific  Difference Between KN95, N95 Facemasks -Vs- Cloth, Surgical, and  Filter Refill 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. Our respirator masks offer a maximum of 99.42% filtration,

The CDC considers KN95 and N95 Facemasks as “critical supplies”. They shield users from floating Covid-19 clouds in indoor air. Cloth, surgical and replaceable filters masks do not provide indoor air protection against inhaling fine viral particles from

Covid-19. That is why front-line health professionals securely choose CDC/FDA Authorized facemasks.

In simple terms, there are 2 mask factors to consider:

  • FILTRATION: This is the foundation for all effective masks. Filters tested for >95% protection against fine covid-19 viral plumes indoors have been Authorized by the FDA/CDC. This is more important than electrostatic properties and snug fit which are secondary to critical Filtration properties.
  • CONSTRUCTION: The entire mask must act as a filter. Untested filter refill masks tend to internally leak. Outer fit is also important if the entire mask can filter to >95%. Masks that are lab-tested for fit alone but not tested for >95% filtration will not protect you indoors. Masks with silver and copper ion electrostatic properties can disable bacteria and virus on masks surfaces but cannot offer >95% protective filtration properties. Biopharmaca offers respirator face masks with all the above properties.

Here is the exact difference: Most masks provide some protection against close range viral droplets from people three to ten feet away. Only KN95 and N95 masks are CDC/FDA Authorized to filter out fine Covid-19 particles floating in indoor air.

Blue Surgical Masks protect users from larger close range particles. They do not protect you from fine Covid-19 particles floating in indoor air. Blue surgical masks are not FDA-Authorized for that purpose like KN95 and N95 respirator face masks.

Cloth and silicon face masks that use refill filters are not proven or tested to work. Filter refills that use >95% filters typically have internal leaks between the replacement filter and the outer seal. KN95 and N95 are fully tested to work whereas filter refill facemasks lack robust testing. That is why filter replacement masks are not trusted by essential medical workers or anyone seeking real protection.

Cloth face masks can help keep you safe from viral droplets three to ten feet away. However, cloth masks, no matter if fashioable, cannot protect you from breathing in fine Coronavirus particles that accumulate and float in indoor air.
