Roger provides clean air in rooms of up to 66 m2 and is ideal for use at home or in the office. With his two sensors this mobile room air purifier continuously measures the quality of the air and immediately detects pollutants such as unpleasant smells, volatile organic compounds (VOCs), fine dust, pollen, viruses and bacteria*. Roger removes 99.3% of coronaviruses (SARS-CoV-2) from the air within an hour**. If the air quality deteriorates, the air quality indicator lets you know by changing colour and adjusts the cleaning performance automatically in intelligent auto mode. The more polluted the air, the higher the level of performance will be. The beautifully shaped air purifier now has a washable, textile pre-filter – as well as an integrated Sanitized® hygiene function. The Dual Filter™ – the heart of the air purifier – is a combination of a HEPA filter and an activated carbon filter. The highly efficient HEPA filter removes pollutants such as fine dust, allergens, pollen, viruses and bacteria from the air while the activated carbon filter adsorbs gases present in the air. Besides the timer function and the night mode, Roger’s impressive features also include Wi-Fi: you can monitor the air quality in real time and control all his functions via an app on your smartphone – so you can even guarantee healthy air at home while you are out and about!

Filtering of viruses

Test results show that air purifier Roger from Stadler Form can remove 99.3% of living SARS-CoV-2 viruses** which cause COVID-19 from the air. According to the United States Environmental Protection Agency (EPA), “when used correctly, air purifiers can help reduce pollutants in the air in residential buildings or enclosed spaces, including viruses.”*** An air purifier like Roger can help reduce the risk of viral infections and thus provide his family and anyone else in the house with the best possible protection against becoming infected with the coronavirus. 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).

CADR 465 m3/h

The CADR (Clean Air Delivery Rate) indicates the volume of purified air that the air purifier can produce. The value is 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 is suitable for rooms of up to 66 m2 and changes the air 3 times per hour. For heavily contaminated room air and for allergy sufferers, Roger is recommended for rooms of up to 39 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 Plus provide the perfect help to free the air of pollutants.

Air quality indicator

Roger 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 pre-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-filter every 3 months while allergy sufferers are recommended to wash it once a month.

Dual Filter™ technology

The Dual Filter™ is the heart of the air purifier. It is a combination of a HEPA filter (H12) and an activated carbon filter. The HEPA filter removes pollutants out of the air, such as fine dust, pollen, viruses and bacteria. Particularly suitable for allergy sufferers – Roger bears 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 shows exactly when the filter needs to be replaced.

Filtering of particles

Roger’s Dual Filter™ produced convincing results during the TÜV test (particle cleaning test). Roger traps 100% of 0.255-micrometre particles (tested based on DIN standard 71460-1:2006). For comparison: a human hair is 80 micrometers thick. So, the filtered particles are 313 times smaller.

Device control via an app (Wi-Fi)

Roger is equipped with Wi-Fi and can be controlled via the smartphone app «Smart Life – Smart Living». The air quality can be monitored and controlled via the app which enables all Roger’s functions to be controlled in real time. An additional child protection function which is only available via the app deactivates the buttons on the device for a chosen period of time.

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

The current version of Roger (as of 2021) has a classic elegance about it. The air purifier now has Wi-Fi which enables the device to be fully controlled via an app on your smartphone. In addition, the grille and the pre-filter have been replaced by an anthracite-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.
