Bad smells, volatile organic compounds, fine dust, pollen, viruses and bacteria can worsen our air quality. Our air purifier Roger little shows the air quality at home or in the office. He continuously measures the quality of the room air with his gas sensor and immediately detects gaseous contamination such as odours or VOCs (volatile organic compound). The air quality indicator lets you know if air quality deteriorates by changing its color. The specially-developed Dual Filter™ combines a HEPA and activated carbon filter. The HEPA filter is very efficient at purifying the air of pollutants and the activated carbon filter skillfully eliminates bad smells. Roger little takes care of his role as a household air improver even more independently with his auto mode which adjusts the cleaning performance to what is currently needed. Roger little is ideal for smaller rooms up to 35 m² and sensitively provides clean and healthy air at home and in the office and lets allergy sufferers take a deep breath.

Polluted indoor air

The air indoors is 2–5 times more polluted than the air outside. We spend approx. 90% of our time indoors and are constantly exposed to this pollution. Typical impurities are volatile organic compounds (e.g. formaldehyde), fine and suspended dust, unpleasant odors as well as viruses and bacteria. Allergy sufferers are also troubled by pollen and the excrement of dust mites. Optimally purified air leads to a great sense of wellbeing, improved vitality, and fewer illnesses. Roger and Roger little provide the perfect help to free the air of pollutants.

AIR QUALITY INDICATOR

Roger little shows the quality of the room air. He continuously measures the quality of the air with his gas sensor. The air quality indicator lets you know if air quality deteriorates due to gaseous contamination by changing its color (blue = good, orange = medium, red = poor).

PREFILTER

The prefilter removes coarse dust particles and dirt from the air. This protects the following filter from heavy contamination and thus optimizes its functionality.

DUAL FILTER™ TECHNOLOGY

At the heart of Roger little, Stadler Form counts on its Dual 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. 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.

FILTER EXCHANGE

The capacity of the Dual Filter™ is limited, which means that it must 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.
