The replacement filter package ensures consistently reliable use of the AIRcleaner Pro over many years. The replacement package consists of 3 different filters: \n \n Pre-filter: \n removes large particles from the air such as hair or skin flakes and extends the service life of the cleaning and filter system \n \n HEPA filter H13: \n filters the smallest particles up to 3 micrometers such as mold spores, dust mites, dust, allergens, fine dust and other pollutants \n \n Activated carbon filter: \n absorbs smoke, odors and TVOC (fumes from e.g. paints, glue, furniture, solvents, etc.) and neutralizes harmful gases \n \nThe filters have been tested and certified in accordance with the filter test standard DIN EN 1822. This guarantees that the room air is cleaned of almost all harmful substances (separation rate >99.995%). \n \nFor long-term hygienic use, we recommend replacing the filter cassettes every year. However, the actual service life is always heavily dependent on the degree of contamination in the air to be cleaned. The sensors built into the device monitor the condition of the filter and inform you when a change is necessary. \n \nReplacing the filter is particularly easy: pull the used filter cassette out of the air purifier from the side and insert the new one - done. No specialist personnel are required for the replacement. This prevents long downtimes and follow-up costs. In addition, no tools are required to change the filter, which prevents the additional spread of viruses and bacteria by tools.
