New European filter standard EN 779:2012. Since 2012 in Europe a stricter standard for air filters is valid. The standard has been changed as follows: • The coarse filter group and test procedure for G groups remain unchanged. • F5 and F6 has changed into medium filters M5 and M6, the test procedure remains unchanged.

EN 779:2012 compact. The new filter classification standard in overview. In Europe and many other countries in the world, the coarse and fine dust filters used in air-condi- tioning and ventilation systems are usually selected in accordance with the classification described in the EN 779 standard entitled “Particulate air filters
The new standard BS EN 779:2012. Filtration of outdoor or recirculation air will reduce the level of pollutants in the air. The basic technology is to pass air through a filter, which retains the pollutant and then to distribute the filtered air in the vicinity of the people, the product or the process in the building. There is a wide range
The EN779:2012 standard used today in Europe to characterize the filtration efficiency of the filters for the ventilation of buildings defines the filtration classes according to the average filtration efficiency of the particles with a diameter of 0.4 µm (see Table 1 below). The convention of using only the filtration efficiency.
The new EN 779:2012 revision takes a further step in fine air filter classification by introducing a minimum efficiency requirement in addition to the average efficiency in classes F7–F9. The minimum efficiency is the lowest 0.4 ?m particle efficiency measured during the complete filter test including discharge treatment of the
