The certified HEPA H13 and activated carbon filter from SCHWAIGER® filters at least 99.95% of the particles with a size of up to 0.1 micrometers from the air. After installation in the appropriate air purifier, the air is cleaned of smoke, pollen, dust or bacteria, for example, and bad smells are removed at the same time. Depending on the period of use and air pollution, the filter can be used for approx. 3 to 6 months without changing.
