A Quick Guide to F8 Pocket Filters

How do pocket filters work?

In simple terms, the purpose of pocket filters (or bag filters as they’re also known) is to remove unwanted particles from air. Their tapered concertina design means they offer high air flow and dust retention capacities without taking up much space, mechanically blocking the flow of particles in the air.

What are pocket filters used for?

Pocket filters are used in HVAC applications to remove dust from ambient air. As they cater for a high dust load and offer flexibility to fluctuations in manufacturing processes, they are often preferred to cartridge filters for final filtration across a number of environments. This includes retail, commercial, healthcare, education, engineering, hotel and leisure and pharmaceutical.

What are they made from?

Originally made using glass fibre media, they now tend to be made out of synthetic media, such as nylon, polypropylene, polyester and progressive microfiber.

What does F8 mean when we’re talking about pocket filters?

Under the old BS EN 779 classification ‘F’ refers to the fact that the filter use is for ‘fine’ filtration and the 8 relates to the size of particle it will block.

Earlier this year, the new global standard of ISO 16890 was introduced. This classifies filter performance according to particulate fractions with the objective of enabling a more precise selection process. Filter efficiencies are determined with regard to the particulate classes of ePM1, ePM2.5 and ePM10.

Under the new 2018 standard, our F8 AirSyntex Air Filters achieve ePM1 at 65%, delivering consistent energy efficient performance.

The key benefits of F8 AirSyntex filters

  • Excellent service life: The tight woven, ultra-fibre structure with two stage filtration ensures high dust holding capacity for longer service life with a low initial and average pressure drop, saving time, energy and reducing costs.
  • Tested according to ISO 16890, EN 779:2012 and Eurovent approved: With these industry standards, you can be confident that the F8 AirSyntex will perform to the highest standards. It is also tested to fire prevention requirements DIN 53438-3 (F1). 
  • Environmentally friendly: AirSyntex filters are Oeko-Tex 100 approved meaning they are free from harmful substances and skin irritants. They can also be fully incinerated, eliminating the need for landfill.
