All Kärcher air purifiers use a specially developed filter design. This consists of a pre-filter, HEPA 13 filter material, and a layer of activated carbon. In addition, all air filters have an antibacterial coating and therefore remove pollutants and unpleasant odours from the air.

Coronaviruses have a diameter of around 0.1 µm. These are present in the air inside the home as part of larger particles. Up to 99.95% of particles of this size (0.3 µm and larger) are removed by the filters.

The air purifiers differ due to the size of the device, the size of the filter, the air flow rate achieved, and their power consumption.

The air purifiers can be operated manually in 3 (AF 20) or 5 fan speeds (AF 30 and AF 50). All units have a smart automatic mode that efficiently regulates the fan speed based on the air quality detected. In sleep mode, the fan sets itself to the quietest level and the units’ lights are turned down. In addition, all air purifiers have a manually adjustable timer that automatically shuts down the units after a preset time. The AF 30 and AF 50 air purifiers also have an environmentally friendly eco mode.

The filter runtime depends on how much it’s used daily and the air quality inside the home. The air purifier displays how long the filter has left and signals when the HEPA 13 filter needs replacing. The average filter life is around 1 year. For hygienic reasons, an annual filter change is recommended.

Whether you should buy the AF 20, 30, or 50 air purifier depends on the size of the room and the place of use. If two models meet your requirements, we recommend choosing the larger air purifier, as it has a higher air flow rate and therefore rids the room of pollutants more quickly.
