Mobile & ultra-efficient AF 100 HEPA 13 air purifier with precision laser sensor & automatic mode to reliably eradicate pathogens & aerosols from the room air. Air purification from the cleaning specialists: The AF 100 HEPA 13 air purifier from Kärcher is a ready-to-go solution for high-traffic & high-occupancy interior spaces such as school classrooms, doctor's waiting rooms or other public facilities. Our new High Protect HEPA 13 Solution filter reliably removes pathogens, such as viruses, & aerosols from the air in the room for an enhanced level of health & safety. An extra coating of silver ions on the filter material also efficiently eliminates germs & bacteria, whilst an activated carbon layer also removes dust, pollen, odours, volatile organic substances, chemical vapours & other harmful substances. A precise laser sensor is integrated for the purpose of continually monitoring the air in the room & controlling the automatic mode. The air quality is displayed at all times in a clear colour-coded diagram; in addition, the current fine dust content in the air & the remaining filtering time can be read off a display at any time. Robust castors allow the purifier to be moved between rooms whenever needed.
