Product Picture & Overview

Doctors, nurses and frontline health care workers are facing shortages of
protective masks. The Food and Drug Administration announced recently that
it will allow use of more widely available masks.

Our product complies with GB2626-2006 standard for healthier protection. It
has also passed the ISO 13485:2016 certification for international quality
management system.

The shape is ergonomically designed for comfort and safety.

OVERVIEW

KN95 is a suitable replacement for N95 masks when they are not available. In
order to ensure the highest quality standards, KN95 must undergo strict testing
in China, where the certification is made. If they are not registered to be be
sold in the domestic market, it is not able to be exported overseas.

Our factory is FDA & CE registered, adhering to the highest standards of quality
assurance.

Production

Spunbonding:
Spunbonding is a process by which fabrics are produced directly from a thermoplastic polymer such as polyester, nylon, polypropylene, or polyethylene.

The molten polymer is extruded through a spinneret, cooled slightly in the air, and laid on a moving conveyor belt to form a continuous web. As the web cools, the fibers bond.

Spunbond fabrics are produced by depositing extruded, spun filaments onto a collecting belt in a uniform random manner followed by bonding the fibers.

Our Spunbound process is continuously running so there is always a team of technicians keeping the quality consistent.

Quality Control

  1. Bacteria filtration efficiency in vitro (BFE). This test works by shooting an aerosol with staphylococcus aureus bacteria at the mask at 28.3 liters per minute. This ensures the mask can catch the percentage of bacteria it’s supposed to.
  2. Particle Filtration Efficiency. Also known as the latex particle challenge, this test involves spraying an aerosol of polystyrene microspheres to ensure the mask can filter the size of the particle it’s supposed to.
  3. Breathing resistance. To ensure the mask will hold its shape and have proper ventilation while the wearer breathes, breathing resistance is tested by shooting a flow of air at it, then measuring the difference in air pressure on both sides of the mask.
  4. Splash resistance. In splash resistance tests, surgical masks are splashed with simulated blood using forces similar to human blood pressure to ensure the liquid cannot penetrate and contaminate the wearer.
  5. Flammability. Since several elements of an operating room can easily cause fire, surgical masks are tested for flammability by being set on fire to measure how slowly it catches and how long the material takes to burn. ASTM levels 1, 2, and 3 are all required to be Class 1 flame resistant.

Filtering facepiece respirators (FFR), which are sometimes called disposable respirators, are subject to various regulatory standards around the world.


Respirators certified as meeting these standards can be expected to function very similarly to one another, based on the performance requirements stated in the standards and confirmed during conformity testing. One notable comparison point is the flow rates specified by these standards for the inhalation and exhalation resistance tests. Inhalation resistance testing flow rates range from 40 to 160L/min. Exhalation resistance testing flow rates range from 30 to 95 L/min.

Based on this comparison, it is reasonable to consider China KN95, as “equivalent” to US NIOSH N95 and European FFP2 respirators, for filtering non-oil-based particles such as those resulting from wildfires, PM 2.5 air pollution, volcanic eruptions, or bioaerosols (e.g. viruses).
