Frequently asked questions about Roger
The LED strip on the front of Roger indicates the current state of the air quality: blue = good, orange = moderate and red = poor. So if the LED strip turns red, that indicates poor air quality. This can be caused by smoke, odours, gases from e.g. wall paint, dust, pet hair, pollen, too much ventilation, room sprays, perfume or deodorant. Roger’s LED strip will also turn red if he is positioned close to ultrasonic humidifiers or aroma diffusers as the individual water droplets will be identified as particles.
Roger removes the smallest particles which are not visible to the naked eye from both the air and respirable dusts. Particles smaller than 2.5 microns which can be deposited in the lungs are described as respirable. Roger adsorbs particles measuring up to 0.2 microns with an efficiency of over 90%. He also filters even smaller particles from the air, but with a slightly lower degree of efficiency.
Roger guarantees optimum air quality in large rooms and can circulate the air 3 times per hour in rooms up to 75 m2. Roger little is designed for smaller rooms and can circulate the air 3 times per hour in rooms up to 35 m2. In addition, Roger is fitted with a gas and a particle sensor while Roger little is fitted with a gas sensor. Both air purifiers filter particles as well as gases from the air.
