The four-layer construction is a combination of internal working layers, i.e. a filtering layer and a special hot air layer, thanks to which a minimum amount of moist air is deposited on the half mask, and outer layers that improve ease of use and mechanical comfort. strength. Half-masks with an exhalation valve facilitate the expulsion of air and are useful for work requiring heavy physical exertion.

PROTECTIVE CLASSIFICATION:

Certified half masks protect the respiratory tract from dust, smoke and mist (aerosol), but not from vapor or gas. In some workplaces, they may be mandatory tools for employees, but we should not forget the dangers to our health when doing household or hobby work, such as sanding walls, working with wood, cleaning the chimney, etc. Abbreviation FFP from English Filtering FacePiece should be translated as filtering half mask and the number behind it from 1 to 3 determines the level of protection. Both the name and the detailed description of the protection levels are described in the European standard EN 149 and, in short, it should be assumed that a higher number means a higher degree of filtration.

FFP1 - filters up to 80% of airborne particles up to 0.6 μm in size. Can be used if the NDS value* is not exceeded more than four times. Most often used in the food industry and the construction industry.
FFP2 - filters up to 94% of airborne particles up to 0.6 μm in size. It can be used if the NDS value is not exceeded more than 10 times. It is most often used in the metal industry and mines, where the presence of harmful aerosols, mists or vapors in the air is common.
FFP3 - filters up to 99% of airborne particles up to 0.6 μm in size. It can be used if the NDS value is not exceeded more than 30 times. Most often used in the chemical industry. They deal with smoke, aerosol particles as well as radioactive, carcinogenic and pathogenic substances such as viruses, bacteria and fungal spores
*NDS, or maximum permissible concentration, is a parameter derived from workplace measurements. It informs the employer about the air pollutants generated during the production/work and the possible consequences for the workers in the tested room.
