Dual Filter™ combination filter for Roger and Roger Big air purifiers.

This combination filter guarantees high efficiency and the best results, using a combination of HEPA filter and activated carbon.

The filters for Roger were jointly developed and manufactured by the world leader in the field of air filtration - the German company Freudenberg Filtration Technologies GmbH & Co. KG (supplier of filters for the automotive industry - Porsche, Audi, Mercedes, Honda).

Dual Filter™ technology is a combination of a HEPA filter and activated carbon.

The HEPA filter purifies pollutants from the air, such as fine dust, pollen, viruses and bacteria.

Activated carbon absorbs unpleasant odors and gases (tobacco smoke, formaldehyde, volatile organic compounds, etc.).
