- Dual Filter™ Technology
At the heart of Roger Little, Stadler Form counts on its Dual Filter™ of HEPA filter and an Activated Carbon filter, developed in cooperation with the German filter specialist Freudenberg. The filter material made in Germany guarantees the best cleaning results. The Dual Filter™ is a combination of a HEPA filter and an Activated Carbon filter.
- High Filtering Efficiency
The HEPA filter removes pollutants out of the air, such as fine dust, pollen, viruses and bacteria. The Activated Carbon filter adsorbs gases present in the air (bad odors, tobacco smoke, formaldehyde, toluene, volatile organic compounds, etc.) and filters them out of the air.
The prefilter removes coarse dust particles and dirt from the air. This protects the following filter from heavy contamination and thus optimizes its functionality.
- Built in Sensor
Roger Little continuously measures the quality of the room air with its gas sensor and immediately detects gaseous contamination such as odours or VOCs (volatile organic compound).
- Air Quality Indicator
Roger Little shows the quality of the room air. It continuously measures the quality of the air with his sensors. The air quality indicator lets you know if air quality deteriorates by changing its color (blue = good, orange = medium, red = poor).
- Auto Mode
Roger Little automatically adjusts its speed with four speed modes according to the air quality of the environment. Roger Little automatically adjusts to a high speed when air quality deteriorates.
- Filter Exchange
The Dual Filter™ is suggested be replaced every 8–12 months, depending on its exposure to air and gases. Thanks to the intelligent filter timer, Roger Little shows exactly when the filter needs to be replaced.
