Our lungs have to work hard every day. Their main function in the respiration process is to oxidize the blood and remove by-products, mainly carbon dioxide. Some work environments contain harmful substances. Our respiratory system has an impressive design, but it cannot handle everything we are exposed to, such as air pollutants. That is why good protection of the respiratory system is very important to keep our lungs healthy.
The most common respiratory protection is dust masks.
In terms of filter efficiency, this protection is divided into 3 protection classes:
class 1 - (FFP1) - filtration efficiency at the level of 80% - products in this category are used to protect against solid and liquid particles with low toxicity (NDS ≥ 2 mg / m3), when the maximum concentration is no more than 4x NDS, (yellow fastening system)
class 2 - (FFP2) - filtration efficiency at the level of 94% - products in this category are used to protect against solid and liquid particles of low or medium toxicity (TLV ≥ 0.05 mg / m3), as the maximum concentration is maximum 10xNDS, (blue fastening system)
class 3 - (FFP3) - filtration efficiency at the level of 97% - products in this category are used for protection against solid or liquid particles of high toxicity (TLV <0.05 mg / m3), if the maximum concentration is not higher than 20x TLV. (red fastening system)
