New 2021 Roger Little. Now with textile pre-filter and sanitized hygiene function.

Roger little – the quiet, efficient air purifier for rooms of up to 33 m2 – filters pollutants and gases, ensuring clean and healthy indoor air. He continuously measures the quality of the air and immediately detects gaseous pollutants such as unpleasant smells or volatile organic compounds (VOCs). If the air quality deteriorates, the air quality indicator changes colour. If the intelligent auto mode is also activated, mobile room air purifier Roger little will adjust his cleaning performance automatically to meet current needs. The more polluted the air, the higher his chosen level of performance will be. The elegant air purifier is equipped with a washable, textile pre-filter which removes coarse dust particles and pollutants from the air and has an integrated Sanitized® hygiene function. At the heart of the air purifier is the Dual Filter™ – a combination of a True HEPA filter and an activated carbon filter. The highly efficient HEPA filter removes pollutants such as fine dust, pollen, viruses and bacteria* from the air while the activated carbon filter adsorbs gases present in the air. Thanks to his timer and LED that can be switched off completely, with Roger little a good night’s sleep is guaranteed!

*None of the information relating to viruses and bacteria is applicable to the USA/Canada.

CADR 231 m3/h

The CADR (Clean Air Delivery Rate) indicates the volume of purified air that the air purifier can produce. Our value was determined by means of independent laboratory tests based on the AHAM standard. Higher CADR values mean that the air purifier can be recommended for larger spaces. The CADR is measured in cubic metres of air per hour. Air purifier Roger little is suitable for rooms of up to 33 m2 and changes the air 3 times per hour. For heavily contaminated room air and for allergy sufferers, Roger little is recommended for rooms of up to 20 m2 – with an air change rate of 5 times per hour.

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 odours 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, Roger little and Roger big 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 sensors. The air quality indicator lets you know if air quality deteriorates by changing its colour (blue = good, orange = medium, red = poor).


The textile preliminary filter removes coarse dust particles and pollutants from the air. By doing this, it protects the Dual Filter™ and prolongs its service life. The integrated Sanitized®** hygiene function protects the preliminary filter against microbial growth. The textile pre-filter can be washed at 30 °C on a cold wash delicate cycle. The antimicrobial protection is guaranteed for at least 20 washes. Based on normal use, we recommend washing the pre-filters every 3 months while allergy sufferers are recommended to wash them once a month.

**Sanitized® is the worldwide leading Swiss producer of the antimicrobial hygiene function and material protection for textiles and polymers.

Dual Filter™ technology

The Dual Filter™ is the heart of the air purifier. It is a combination of a True HEPA filter and an activated carbon filter. The HEPA filter removes pollutants out of the air, such as fine dust, pollen, viruses and bacteria. Roger little is particularly suitable for allergy sufferers, having been awarded the ECARF quality seal. The activated carbon filter adsorbs gases present in the air (bad odours, 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.

Filtering of particles, especially viruses

Roger little’s Dual Filter™ produced convincing results during the TÜV test (particle cleaning test). Roger little filters 100% of 0.255-micrometre particles (tested based on DIN standard 71460-1:2006). For comparison: a human hair is 80 micrometres thick. So, the filtered particles are 313 times smaller. An additional test confirmed: air purifier Roger little efficiently filters 99.9% of all influenza A viruses*** and aerosols from the air in 60 minutes (tested in a 28 m3 test chamber).

***Spanish flu (H1N1), H1N2, Asian flu (H2N2) and Hong Kong flu (H3N2)

Version of Roger little up to the end of 2020 vs. the current version of Roger little

The current version of Roger little (as of 2021) has a familiar elegance about it. With the current version of Roger little, the grille and the pre-filter from the earlier version (up to the end of 2020) have been replaced with an anthracite- or light grey-coloured textile pre-filter with integrated hygiene function.

AHAM certified room size is the size of room in which the air purifier can provide a full five air changes per hour. Therefore refreshing all of the air in the room through its filters once every twelve minutes.This is more relevant than 'maximum' room size which does not reflect an air purifiers genuine effective capability.Always be sure to only use the 'AHAM certified' room size for true comparison purposes.
CADR stands for Clean Air Delivery Rate and is an actual measurement of the amount of filtered air provided by the machine.This is the only true way to compare like for like between air purifiers when assessing how powerful they are. CADR is not the same as air volume which will always appear higher due to the fact that it is only a measurement of the units fan power (with no filter Installed).
***Carbon Filters
Carbon filters remove chemical fumes including VOC's, traffic combustion gases, pet odours, tobacco smoke and many more gaseous pollutants.However not all carbon filters are the same. Basic carbon 'sheet' filters are generally lightweight and have little capacity to adsorb these pollutants effectively. On the other hand filters containing actual carbon 'granules' are infinitely more effective and should always be chosen over carbon sheets where the most effective gaseous pollutant removal is required.
