QUIET YET EFFICIENT: The Airmega 250 can clean a space of up to 52m² and 2.4 metres in height in just 15 minutes. The device can also be used in “Rapid Mode” for faster purification with an extra boost and will continue to purify the space until the air is completely clean. The Airmega 250 sleep mode functions with just 22dB which means the device can hardly be heard. CLEAN AIR IN SPACES UP TO 131m²: The HyperCaptive Filter and GreenHEPA provide double protection and remove up to 99.999% of harmful particles with a nano-size of up to 0.01μm including allergens, bacteria, animal hair, fine dust, mites, mould, odours, pollen and viruses. The filter inactivates them by capturing them in the GreenHEPA PM10 & PM2.5. SMART MODE FOR ENERGY SAVING: In smart mode, the device automatically adjusts the fan speed to the air quality and thus works with very high energy efficiency without affecting the performance. TIMER FUNCTION: The Airmega 250 can run for 1, 4 or 8 hours. Using the easy timer function the device can be set up to turn off automatically helping to avoid any unwanted energy consumption.
