Pleated cassette filters with activated carbon – odour and gas adsorption filters

Pleated cassette filters with activated carbon – effective odour and gas filtration

Pleated cassette filters with activated carbon are adsorptive air filters designed to remove odours, gaseous pollutants and volatile organic compounds (VOCs) from supply and exhaust air.

By combining pleated filter construction with activated carbon media, these filters provide efficient gas-phase filtration while maintaining a compact format suitable for a wide range of ventilation and air conditioning systems.

They are used wherever particle filtration alone is insufficient and odour or gas contamination negatively affects comfort, safety or process conditions.

Adsorptive filtration principle

Activated carbon filters work on the principle of adsorption.
The activated carbon material has a highly porous structure with a very large internal surface area, allowing gaseous contaminants to be captured and retained within the carbon pores.

This enables effective removal of:

• Unpleasant odours

• Smoke and fumes

• Chemical vapours

• Cooking-related smells

• Industrial gaseous emissions

Adsorptive filtration significantly improves perceived air quality and indoor comfort.

Filter construction and materials

Pleated cassette filters with activated carbon feature:

• Pleated filter media, increasing the effective filtration surface

• Activated carbon material, integrated into the filter structure

• Flat cassette design for easy installation and replacement

The pleated construction ensures stable airflow distribution and supports efficient use of the activated carbon material.

Key advantages

• Effective elimination of odours and gaseous contaminants

• Removal of VOCs and chemical fumes

• Improved indoor air quality and user comfort

• Compact cassette format

• Easy installation and replacement

• Suitable for a wide range of HVAC systems

• Manufactured in Europe

• Available in custom dimensions

Typical applications

Pleated cassette filters with activated carbon are widely used in:

• Residential buildings – elimination of cooking and household odours

• Offices – improved comfort and indoor air quality

• Restaurants and bars – removal of food-related smells

• Commercial facilities – shops, hotels and public spaces

• Industrial environments – reduction of chemical fumes and gaseous emissions

These filters are suitable for applications ranging from comfort ventilation to industrial air treatment.

System integration

Activated carbon cassette filters are typically installed as a dedicated gas-phase filtration stage, either on their own or in combination with particulate filters.
