This disposable KN95 non-medical respiratory face mask with the certified
GB2626 equivalent to the European standard EN14683, is designed to help
provide a reliable respiratory protection against dangerous airborne
particles such as Covid-19 virus.
With a Certified 95% Filtration Efficiency, this mask reduces inhalation
exposure by filtering at least 95% of airborne particles, which are small
enough to be inhaled such as respiratory droplets carrying contagious
viruses and bacteria.
This disposable KN95 non-medical respirator face mask is on the Emergency Use Authorized FDA list. (manufacturer Jinhua Jiadaifu)

The mask consist of a metal nose clip and earloops.
The material consists
of five layers. The outer layer is a white non-woven fabric, the second and
fourth layer are melt blow non woven fabric.
The third layer is hot air cotton,
and the fifth layer, which is the inner layer, is a skin friendly non woven
The nose clip is placed inside the fabric, to make it more durable.
Because of the secure fit, glasses does not fog up.
Melt Blow non-woven fabric is an important raw material for the production of face masks, commonly known as the "heart" of the masks. It is a conventional fabrication method of micro- and nanofibers where a polymer melt is extruded through small nozzles surrounded by high speed blowing gas. It has good filtering, shielding, heat insulation and oil absorption properties. It can filter out viruses attached to body fluids. It mainly plays an indispensable filtering role in KN95 face masks.
Hot air cotton non-woven fabric is a kind of filling material in KN95 face masks. In order to balance the effect of warmth and protection, some manufacturers use hot air cotton non-woven fabric with high bulkiness, good elasticity, soft feel, strong warmth and good air permeability. It is sandwiched between the KN95 folding masks, which mainly plays the role of heat insulation, moisture and moisture resistance, and improves the wearer's comfort.
As opposed to traditional materials, such as cotton, linen, wool, and silk; non-woven fabrics do not necessitate weaving or knitting. They are broadly defined as sheet or web structures bonded together by entangling fiber or filaments mechanically, thermally, or chemically.
