“How ISO contributes to a sustainable world – 2008”
Recent studies performed in Denmark by G. Bekö(1) The study showed that the overall economic and social benefits of using particle air filtration are several times larger than the associated running costs.

The cost of ventilation
• The energy requirement for ventilation is expensive.
• Filters account for approx. 30% of the total energy cost of the system. (C.I.B.S.E. data)
• Filters are the most inexpensive part of the system to improve.
• Without Capital Without Capital ExpenditureExpenditure
30% of total system pressure loss

Choosing the right filter saves energy
•Actual design of the filter that has the main impact
•Full utilisation of the media resulting in extended life and low energy cost.
•Must have lowest average pressure drop
•Minimum air filter efficiency to European standard EN779:2002
