Air Purifier Kärcher AF 20 20 m² 24 W White

The Kärcher AF 20 air purifier is designed for rooms up to 20 m² and delivers efficient filtration with a low 24 W power draw. Its multi-layer filter system, including a HEPA-grade element and active carbon fill, removes allergens, pollutants and pathogens. The device displays numeric PM2.5 values in µg/m³, shows air quality via a colour code, and reports temperature and relative humidity. Compact and lightweight, the AF 20 is suitable for small living spaces, children's rooms and individual workstations.

Advantages

The AF 20 combines a HEPA-class filter with activated carbon to achieve a filter efficiency of 99.95% for 0.3 µm particles and includes a high-quality laser particle sensor for automatic mode. Useful functions include an adjustable timer, child safety lock, night mode and ultra-silent operation. Automatic mode and fan speed adapt to measured air pollution levels. Typical filter lifetime is around one year, depending on pollution and usage intensity.

For manual operation choose the required performance level or activate night mode for minimal noise. Use the timer to schedule operating periods and enable the child lock to prevent accidental changes.

Usage recommendations

Replace the filter according to the device indicator or at least once a year, depending on air pollution and usage. Regularly clean the exterior and keep intake vents free from dust. Place the purifier away from direct sunlight and heat sources for optimal performance.
