POCKET FILTERS

Pocket Filters – efficient air filtration for AHU & HVAC systems

Pocket filters are one of the most widely used filtration solutions in professional air handling units (AHUs) and HVAC systems. Thanks to their large filter area, high dust-holding capacity and broad applicability, they serve as a key component in coarse, pre- and fine filtration. Pocket filters are available in various ISO 16890 classes, materials and pocket configurations, ensuring the right filter for every installation.


Why pocket filters?

The characteristic multi-pocket structure provides a large effective filter surface, resulting in a low initial pressure drop and long service life. Depending on the filter medium – synthetic, fiberglass or Nanowave – pocket filters can meet a wide range of air-quality requirements:
- Efficient removal of coarse and fine dust per ISO 16890 (ePM10, ePM2.5, ePM1)
- Long service life due to deep dust-loading capacity
- Choice of materials: synthetic, fiberglass or advanced nanofiber media
- Suitable as prefilter or fine filter in multi-stage systems
- Broad compatibility with standard AHU & HVAC configurations


Types of pocket filters

Each type offers specific advantages depending on the required energy efficiency, air-quality level and operational conditions.


Typical applications

– Office buildings & commercial facilities
– Schools, healthcare and public buildings
– Retail, hospitality and commercial HVAC
– Technical rooms & light industry
– Data centres & production environments
– AHUs with standard to high air volumes
