The importance of Air 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.

Activities


Although the air filter group is not currently an independently active group it still has relevance and presence in a number of other groups.
If there are queries about air filtration guidance, technical standards or applications please contact Peter Dyment vice chair of the IAQ
group.
Members of FETA and others who have a special interest in air filtration are welcome to make contact info@feta.co.uk
