Stadler Form Roger Big Air Purifier (R-018A)

What room size can the Roger Big effectively clean?

The Roger Big is designed for large spaces up to 104 square metres (1100 square feet). It completely exchanges the air three times per hour in rooms of this size, making it suitable for conference rooms, open-plan offices, large living rooms and master bedrooms. For smaller rooms, it will provide even more frequent air changes and faster cleaning.

How do the dual air quality sensors work?

The Roger Big features two independent sensors that continuously monitor different aspects of air quality. One sensor measures particulate matter (PM2.5) whilst the other detects gases and odours. These sensors provide real-time data to the intelligent auto mode, which automatically adjusts fan speed and filtration intensity based on current air quality conditions, ensuring optimal performance without manual intervention.

What type of filters does the Roger Big use and how often should they be replaced?

The unit uses two dual-filter systems, each combining H12 HEPA and activated carbon filtration. The H12 HEPA filters capture 99.5% of particles down to 0.3 microns, whilst the activated carbon removes odours and gases. Filter replacement frequency depends on usage and air quality conditions, typically every 6-12 months. The app provides filter life monitoring to indicate when replacement is needed.

Can I control the Roger Big remotely through my smartphone?

Yes, the Roger Big includes WiFi connectivity and works with a dedicated smartphone app. You can monitor real-time air quality readings, adjust fan speeds, set schedules, activate child lock and receive filter replacement notifications. The app provides complete remote control functionality, allowing you to manage the unit from anywhere with internet access.

How loud is the Roger Big during operation?

The maximum noise level is 58dB, which is comparable to moderate rainfall or quiet conversation. At lower fan speeds, the unit operates much more quietly. The intelligent auto mode automatically adjusts fan speed based on air quality, so it only runs at higher speeds when necessary, maintaining quieter operation most of the time whilst still providing effective air cleaning.

Is the Roger Big suitable for people with allergies or asthma?

Yes, the H12 HEPA filtration captures 99.5% of allergens including pollen, dust mites, pet dander and mould spores down to 0.3 microns. The activated carbon component removes odours and chemical irritants. The continuous air quality monitoring and automatic adjustment ensure consistent allergen removal, making it particularly beneficial for people with respiratory sensitivities or allergies.

Does the unit have any safety features for households with children?

The Roger Big includes a child lock feature that can be activated through the smartphone app, preventing children from changing settings or turning the unit off. The sturdy construction and smooth-rolling wheels allow safe repositioning, whilst the app control means you can adjust settings without children accessing physical controls on the unit itself.

What maintenance is required for the Roger Big?

Regular maintenance involves replacing the dual filters every 6-12 months depending on usage and air quality conditions. The app monitors filter life and provides replacement notifications. The exterior can be cleaned with a damp cloth and the air quality sensors may occasionally need gentle cleaning to maintain accuracy. The unit is designed for minimal maintenance with most care focused on timely filter replacement.
