Activated carbon plays a decisive role in air filtration, particularly in adsorbing harmful gases such as ozone, nitrogen dioxide, sulphur dioxide and volatile organic compounds (VOCs).
EMW® activatedcarbon compact filters are the ideal solution for efficient adsorption of harmful substances. The activated carbon compact filters are used in ventilation and air conditioning systems, in the chemical and pharmaceutical industries, in ventilation technology and for extraction at workplaces for the adsorption of gaseous substances.
Rely on the EMW® compact activated carbon filter, classified in accordance with ISO 10121-3, to effectively reduce harmful substances and sustainably improve air quality.

Activated carbon compact filters from EMW® offer an immense inner surface area, which enables a high adsorption capacity. This allows harmful gas molecules to be effectively bound to the activated carbon.
Technical data - Filter class vLD 45 in accordance with ISO 10121 for the harmful gas toluene, which serves as a reference gas for organic compounds (VOC).
Harmful gases such as ozone, nitrogen dioxide, sulfur dioxide and volatile organic compounds (VOCs) have molecular sizes in the nanometer range, while conventional air filters (such as (H)EPA filters) primarily capture particles in the micrometer range. Therefore, filtration with ordinary air filters is often not enough to effectively remove these harmful gases.
Activated carbon filters, on the other hand, use two main mechanisms to adsorb harmful gases. During physisorption, the molecules adhere to the surface of the activated carbon, while during chemisorption they form chemical bonds. These two processes enable effective separation of gaseous contaminants.
EMW® activated carbon filters are able to adsorb a wide range of harmful gases. They therefore offer a comprehensive solution for air purification.

The risks posed by air pollution are now recognised as the greatest threat to human health1. Harmful gases are also increasingly coming into focus.
Almost in the same breath, there are innovations to report regarding the ISO 10121 test standard for activated carbon air filters! Part 3 of the series of standards has been active since 2022. The third part establishes a new classification system for activated carbon air filters with the filter classes Light Duty (LD), Medium Duty (MD) and Heavy Duty (HD).
