FFP2 KN95 Foldable Respirator Face Mask
Suitable for respiratory protection, filter-ing dust, haze, bacteria, droplets andother harmful particles in the air.
Open the face mask, put on the bridge of the nose, press the bridge of the nose. Press down on metal clip and a W shape should form covering your nose and conforming to the shape of your cheek under your eyes. This will ensure the best fit possble.
What is a KN95 FFP2 Respirator Face Mask?
A KN95 face mask is a respiratory face mask designed to stop 95% of particles >0.3 microns in size. It is designed to prevent the wearer from inhaling any airbourne particles or droplets, particularly very fine particles or droplets suspended in the air
What is the difference between a Respirator Mask and a Surgical Mask?
A Respirator Mask is designed to protect the wearer from inhaling any airbourne particles or droplets and aerosols. A Surgical Mask is designed to primarily protect a patient from the exhaled droplets of the wearer’s nose and mouth. It can provide the wearer with some protection against larger droplets but is not as effective against finer aerosols.
