Air purifier AF 20

Fast air purification in rooms of 20 m²* – 40 m²: the compact AF 20 air purifier with H13 filtration and activated carbon reliably removes pathogens, fine dust, allergens and odours.

Perfect air purification for small rooms, children's rooms and individual workspaces – the AF 20 air purifier cleans indoor air of allergens, pollutants and pathogens by means of its multi-layer filter system. Other features include the active carbon fill, as well as a display to alphanumerically indicate the air quality in PM2.5 particles in µg/m³ and the air quality via a colour code. The air purifier also makes an excellent choice on account of its timer function, child safety lock, night mode and ultra-silent operation, as well as a filter efficiency of 99.95% for 0.3 µm particles and a high-quality laser sensor for the automatic mode. This means that the automatic mode and the performance level adapt automatically to the level of air pollution. Moreover, the filter has a service life of around one year, depending on the level of air pollution and the intensity with which it is used.
