In heavy work, more air per minute is used than in light work. the user’s physical characteristics: The quantity of air that passes through the filter determines how much contamination the filter is subjected to. The service life of filters therefore differs between different work environments. Contamination and mixtures of types of contamination: Contamination and mixtures of types of contamination affect filters to different extents. Warmer air and high humidity contain considerably more water per unit volume. Humidity and temperature: Humidity and temperature are important parameters, and high humidity generally shortens the service life of a filter. A high concentration means a shorter service life, and a low concentration means a longer one. Concentration: The concentration of the substance is a very important factor in assessing the service life of a filter. Below are a number of factors affecting the service life of a gas filter. Using smell or taste as a sensor is not always feasible, because many substances have no clear properties of smell or taste. This is especially important in the case of gas filters, since these lose their purifying effect when they are saturated. It is important that the employer draws up a respiratory protection programme containing clear information about when a filter should be replaced.
