Product information Roger little

Roger little – the quiet, efficient air purifier for small rooms – filters pollutants such as fine dust, pollen, viruses and bacteria from the air. He measures the quality of the air continuously, detects gaseous pollutants such as unpleasant odours or volatile organic compounds (VOCs) immediately and reliably filters them out of the air. His washable pre-filter protects the Dual Filter (HEPA and activated carbon filter) and extends its service life.

The air purifier to combat viruses and bacteria

The air purifier Roger little by Stadler Form can efficiently filter viruses and bacteria from the air. According to the US Environmental Protection Agency (EPA), air purifiers can help reduce airborne pollutants, including viruses, in residential or indoor environments when used properly. An air purifier like Roger little helps reduce the risk of indoor infection from viruses and bacteria.

The recommended room size is based on the CADR value (Clean Air Delivery Rate), which indicates how much clean air the device produces per minute. The calculation is based on the desired air exchange rate per hour. We calculate a 1-time air exchange per hour: Room size (m²) = (CADR value in m³/h) ÷ room height (m). Example: An air purifier with a 465 m³/h CADR in a room with a 2.5 m ceiling height is suitable for approximately 186 m². If a higher air exchange rate is required, the recommended room size decreases accordingly.

Remove the material from the two positioning aids, the two pins, the 4 tabs and the two corner tabs at the top of the plastic frame. To attach the textile pre-filter to the appliance again, stretch the material over the plastic part so that the washing label is at the top and on the inside. All openings in the material to be threaded through are marked with bright-coloured thread. In addition, the material should be lifted over the two corner tabs at the top of the appliance.

The textile pre-filter can be washed at 30 °C on a gentle cycle. Let the textile pre-filter dry completely before attaching it to the appliance again. Caution: Never put the pre-filter in the dishwasher!

Roger little uses a Dual Filter™ system – a powerful combination of a HEPA H12 filter and an activated carbon filter – to purify the air. The textile prefilter removes coarse dust particles and pollutants from the air, thus protecting the Dual Filter™. The prefilter is protected against microbial growth by its integrated Sanitized®* hygiene function. The antimicrobial protection for the prefilter is guaranteed for at least 20 washes on a delicate wash cycle at 30 °C.

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

Is an H12 filter class sufficient? We address that question in this video.

Roger little comes with a HEPA H12 Dual Filter™ as standard. A HEPA H14 filter can be purchased as a separate accessory.
