The intelligent AirgoClean 250 E is a fully automatic, high-performance purifier with air quality sensors that enable the unit to clean the air with an intelligently controlled performance.
The air quality sensors continuously monitor the room air for air quality and fine dust pollution. The four-stage air quality indicator makes the otherwise invisible air quality visible. Combined with three-stage adjustable ventilation, with a maximum air circulation rate of 740 m³/hour, it provides a noticeable improvement in air quality in rooms up to 88 m² or 220 m³.
Double 3-in-1 HEPA filter technology with ionization removes bacteria, viruses, pollen, dust mite residue, mould fungus spores, and other allergens from the air.
With pre-mounted filters on both sides of the unit, the 2 x DACRON® prefilters, 2 x HEPA filter (99.97 %), and the 2 x double activated carbon filters – are effective against house dust, odours, pet allergens, cigarette smoke, smog, and particles which can carry smells and viruses. The uncomplicated, quick filter change ensures easy operation.
In automatic mode*, the fan speed and the associated air cleaning performance are controlled depending on the air quality:
Blue: Outstanding air quality PM2.5 (diameter of >2.5µ) value 0 – 55
Green: Good air quality PM2.5 value 56 – 100
Orange: medium air quality PM2.5 value 101 – 150
Red: Poor air quality PM2.5 value > 150
With the four-stage filter quality display, you will never miss the right time to replace the HEPA filter. The graphically designed bars provide information about the remaining time until the filter change.
A timer that can be set in 1-hour steps automatically switches the device off after the preset time. This saves energy and you don’t have to worry about switching off after a hard day at work in the home office or when going to bed.
The noise-reduced night mode with dimmed lighting enables cleanly filtered room air even during sleep. The air flow is automatically adapted to the need for sleep and the air output is regulated to the lowest ventilation level.
