These disposable face masks can be useful for protection of various kinds of airborne contaminants. They help to prevent you from inhaling allergens and irritants like pollen, airborne particles, chemicals, biological contaminants and viruses.
These disposable facial masks are ideal for keeping on hand for both dust and other particles, chemical and vapour removal. The level of protection is determined by the FFP rating. The rating is: FFP2 is 92% and FFP3 is 98% efficient. This is based on the total inward leakage of air around the edges of the mask. Higher levels of efficiency are achieved with a better face seal and will depend upon the concentration of contaminants.
The electrostatic material in the disposable masks below has been tested down to 0.5 microns. They are designed for eight hours of use. When not in use store in a sealed bag away from direct sunlight. Leaving the mask in sunlight will cause the straps to dry out and deteriorate.
