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 big 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.
No, you don’t have to activate Wi-Fi and Roger big can also be used without the Smart Life app.
