Whether it’s up against fine dust, pollen, odours or pathogens, Roger from Stadler Form knows how to get rid of them. Roger is fitted with a variety of sensors that measure air quality, enabling it to take appropriate action. And how does it do that, you ask? Well, it comes with a dual filter. While the HEPA filter removes pollutants, the activated carbon filter eliminates undesirable odours from the air. A built-in filter informs users about the air quality. Roger can work independently in different modes. What’s more, Roger has a CADR value of 521 m3, which provides details about the clean air produced per minute and the elimination of dust, pollen and smoke.
