Pocket filter

Pocket filters from konfAir, or bag filters as they are also called, are mainly used to improve the air quality in industrial, commercial and residential buildings, where they fit in most standard plants.


High quality bag filter for ventilation

konfAir offers pocket filters/bag filters in qualities according to ISO 16890. We produce our filters at our own factories in Denmark and in Lithuania, which means that we have both a high degree of flexibility and a short delivery time.

We produce our pocket filters with welded and dimensionally stable frames. The frames can also be delivered in metal on request. Our pocket filters for ventilation are all made of synthetic filter media, which among other things has the advantage that it can withstand a humid environment. Depending on the quality, the synthetic filter media has up to 3 layers which ensures depth filtration and thereby an effective filtration is achieved. This depth filtration and the construction of the pockets help to keep the pressure drop to a minimum throughout the lifetime of the filter – which benefit both your customer's energy costs and the environment.

Premium: High-quality energy filter. Used when low pressure drop and low energy consumption are desired.

The filter material is built up in a layered structure for optimal depth filtration. For example is our F7 quality built in 3 layers, each doing its job - one layer for each size of particles. This results in efficient filtration, where the particles are distributed as best as possible on and in the filter material.

Below are sketches showing the difference between surface filtration and depth filtration.

It is obvious that the air gets through the filter easier when the dust particles are evenly distributed throughout the filter media.

This depth filtration and the structure of the pockets help to keep the pressure drop to a minimum throughout the lifetime of the filter - which benefit both your customer's energy costs and the environment. In addition to offering pocket filters in customized sizes, we also offer the following special solutions at konfAir:

  • Slanted pockets where space is tight
  • Pockets with straps for vertical airflow
  • Filters with metal brackets where the pockets are required to be stiff (grease, oil fumes)
  • Carbon pocket filters (odor problems)
  • Pocket filters with metal frames
  • Mounting frames



At konfAir, we can also label each filter with your own information, e.g. plant number and location.
In addition, we can offer to add your company name to packing lists if you wish us to ship goods directly to your end customers.
