Kärcher AF 20 – Compact, High‑Efficiency Air Purifier for Cleaner Indoor Air

The Kärcher AF 20 delivers fast and reliable air purification for bedrooms, small offices, children’s rooms and other compact indoor spaces. Its multi‑layer filtration system—combining an H13 HEPA filter and activated carbon—removes 99.95% of particles as small as 0.3 μm, including dust, pollen, allergens, airborne pollutants, pathogens and unwanted odours. With a maximum airflow of 220 m³/h, it refreshes room air quickly and effectively.

A built‑in laser air quality sensor enables precise automatic regulation. The AF 20 continuously monitors PM2.5 levels and adjusts its performance based on real‑time air quality. Its display provides both numerical readings (µg/m³) and a clear colour‑coded indicator, allowing users to easily understand air purity at a glance.

For everyday convenience, the AF 20 includes a timer function, night mode, child safety lock and ultra‑quiet operation—ideal for use during sleep or focused work. The long‑life filter lasts up to one year, depending on room conditions and usage intensity, and a filter‑change indicator ensures optimal performance.

Compact, lightweight and energy‑efficient at only 24 W, the Kärcher AF 20 is a dependable solution for maintaining cleaner, fresher air in smaller living and working spaces.
