78 *MAK value = maximum workplace concentration. It indicates the maximum, permitted concentration of a material in the air for which no health damage can be expected, even when one is exposed to it for 8 hours a day, 40 hours a week. P: filtering of noxious dusts, smoke, aerosols Kerbl respirators help to respond optimally to threats by pollutants and to protect yourself from them safely. All respirators are Category 3 Personal Protective Equipment (irreversible health damage) in accordance with EU Directive 2016/425. Breathing valves make them more comfortable. The filter classes provide information on the maximum concentration of harmful gas in the air: The lifetime of filters depends on the humidity and temperature of the inhaled air, the chemical composition of the gases or the storage conditions. This means a general lifetime cannot be specified. Change the filter as soon as you notice the first unpleasant odours or inhaling becomes difficult as the filter has bonded together.
