Roger little – the quiet, efficient air purifier for rooms of up to 335 square feet, perfect for small bedrooms, dorm rooms, and offices, filters pollutants and gases, ensuring clean and healthy indoor air.
Just like Roger and Roger Big, it 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 color. If the intelligent auto mode is also activated, the 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 that 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 an H12 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.
Roger little removes 99.3%** of coronaviruses (SARS-CoV-2) from the air in an hour. And thanks to his timer and LED that can be switched off completely, with Roger little a good night’s sleep is guaranteed!
CADR 465 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 feet of air per hour.
Air purifier Roger is suitable for rooms of up to 335 sq. ft 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 215 sq. ft – with an air change rate of 5 times per hour.
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 color (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. 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 odors, tobacco smoke, formaldehyde, toluene, volatile organic compounds, etc.) and filters them out of the air.
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 filters 100% of 0.255-micrometer particles (tested based on DIN standard 71460-1:2006). For comparison: human hair is 80 micrometers thick. So, the filtered particles are 313 times smaller.
