Protective filter P-20 anti-particle from Czech Company Avec Chem has a very high filtration efficiency.
The filtration efficiency of P3 R filters is higher than 99.9999 %.
The filter will reliably protect the respiratory organs against solid and liquid aerosols, smoke-forming substances, dangerous microorganisms (bacteria, viruses, spores, etc.) and fibroplastic particles (asbestos, etc.)
Anti-particle filters and filter inserts are made of folded special microfiber filter paper. The folded anti-particle insert, which the filter is fitted with, has an optimal capture surface, low breathing resistance and captures a very wide range of particles such as dust, aerosols and smoke with high efficiency.
Filter with a round thread EN 148 make a great connection with mask from the same manufacturer. Together they create maximum protection of your health in any environment.
The time of use of the filter limits only the clogging of the outside of the filter.
The estimated time of use in a very dusty environment (desert, buildings) is couple of hours, in a sterile environment (laboratories, etc.) the use is not theoretically limited, practically weeks; in the hospital environment it is usually couple of days.
The filter should always be replaced when the respiratory resistance increases due to its clogging.
