From the Archives – A new way of comparing air filters – put your supplier to the test

We are featuring the best of our most popular content from 2012. Please share and comment! We would appreciate your feedback.

This post explains the Eurovent energy classification which facilitates filter comparisons giving customers a clearer understanding of a filter’s annual energy consumption. It also highlights the health and financial implications of poor indoor air quality. Within the post, we have included an Energy Efficiency Classification Document to help buyers to find the correct air filters to suit their requirements.

There is a good chance that, at this very moment, you are breathing clean air that has passed through a filter manufactured by us. Our products can be found everywhere from offices to clean rooms for sensitive electronics production, schools, mines, factories, hospitals and nuclear power stations.

Filters are now graded from A to G, with “A” standing for the lowest energy consumption and “G” for the highest. The new classification, based on EN779:2012**, gives customers a clearer understanding of a filter’s annual energy consumption, initial efficiency and minimum efficiency. To reflect this new classification system, Camfil Farr is now changing the labels and product names of filters to include the new A to G energy rating. This information clearly points out the difference between our filters and competitor products, making it easier to select the right filter for the right application for the best energy efficiency and filtration.

Camfil argues that better indoor air quality (IAQ) can help businesses reduce energy costs and carbon emissions, while also improving the health and productivity of employees.

The best air filtration systems can help businesses protect employees from 90 per cent of air pollutants for up to 90 per cent of the time. Ask yourself the question: does our ventilation system include regularly maintained air filters that comply with European guideline EN 13779 and if not, why not?

At Camfil we are looking to highlight the health and financial implications of poor indoor air quality, which can often be more harmful than outdoor pollution. The UK has the highest rate of illnesses caused by water systems, dampness and mould, ventilation and conditioning systems and building materials in the European Union.

“Apart from energy consumption the label gives other valuable information such as the rated air flow of the filter, in this case 3400 m3/hour. Air Quality performance is given by the (ME) Minimum Efficiency figure. In this example, 54%. Initial efficiency may drop to drastically low levels with some synthetic media filters”

Energy efficient filter performance must be linked to the particulate efficiency of the filter. Particulate efficiency % is the ability of the filter to remove health damaging fine particles from the airstream.

For a more detailed explanation of why (ME) minimum efficiency is a better indicator of consistent life performance read the associated article on the new EN779:2012 test standard.

Filter users are increasingly looking for good clean Indoor Air Quality with the best energy efficient performance. This new label will assist but to guarantee a good clean Indoor Air Quality. EN13779:2007 advises minimum F7 classification. Remember check for minimum efficiency. Ideally ME should be 55% to 60% for an F7 filter.

At last, buyers of air filters will find it a lot easier to find the right filter– regarding both energy efficiency and indoor air quality. *Eurovent‘s new, objective energy efficiency classification has now been implemented. Now all air filters can be graded from A to G – A for the lowest energy consumption and G for the highest. The new classification is based on EN779:2012 and will give you a good understanding of annual energy consumption, initial efficiency and minimum efficiency.

Put your supplier to the test – Many suppliers do not test their filters properly, making it impossible for customers to compare different brands. At Camfil, we test all our filters to guarantee a high standard of quality. Does your air filter supplier have what it takes?

The most important part of indoor air quality is the cleanliness of the air. Air contamination consists of particles, gases and vapours that may reduce the well-being and health of humans and decrease the output and efficiency of production processes. It will alwayspay to use the right filters in ventilation systems.
