Membership of the Filter Group

Membership is open to any company or organization involved in the manufacture and supply of air filters and air filter materials.

A list of member companies can be found by clicking the Members List

The aim of the group

To represent and promote the UK air filter industry. The membership is committed to the correct promotion, selection and application of air filters within HEVAC systems and clean air technologies. The membership can be relied upon to provide impartial guidance.

The importance of Filtration

Air filtration is a fundamental process in the provision of clean air. The quality of clean air is entirely controlled by the use of correctly selected, installed and maintained air filters. Air filtration provides the means of obtaining the level of particulate cleanliness required;

  • To provide healthier and more comfortable living and working conditions for occupants of buildings.
  • To reduce the risk of infection in hospital 'critical areas' or other related environments.
  • To prevent the contamination of foodstuffs, pharmaceutical products and delicate electronics during manufacture.
  • To prevent the build up of contaminants on heater or condenser coils and other ventilation system components.
  • To protect expensive or delicate machinery from avoidable wear and subsequent maintenance and/or replacement.
  • To prevent the ingress or emission of hazardous substances
  • To protect the external environment from internally generated process dusts, gasses and contaminants.


Members are actively involved in the development of air filtration technical standards as applied to HVAC and Clean air technologies both nationally and internationally.

Members participate in the Eurovent certification scheme for HEVAC filters.
