The cost of clean air

The crude oil price has more than doubled over the last few years and the cost of electricity is steadily growing in all countries. Furthermore, developing countries are increasingly becoming more industrialised and their energy needs are soaring.

The filters are the most inexpensive part to improve

It is well known that building ventilation costs
are significant. The 'typical' energy cost of
filters as a percentage of the total system is
approximately 30%. Selecting the correct filter,
i.e. F7 filter efficiency and lowest average
pressure drop, can create significant
savings on energy while maintaining healthy
Indoor Air Quality (IAQ).

1PA = 1 Euro

A rule of thumb, for a typical installation
running half time over one year, is that one
additional Pascal in pressure drop over a
filter adds 1 Euro in extra energy cost. A
bad filter construction could add 50 Pascal
compared to a “good” construction, even
when the same filter class is used. In other
words it adds 50 Euro on the annual energy
bill.
