The old BS EN 7filter grades (Gto F) have been replaced with a new filter classification system. Our range of high quality pleated panel air filters are designed for use in HVAC air handling systems.
Filter efficiency for particle size range 0. The addition of new requirements on minimum filtration efficiency (ME) for fine air filters (F Fand F).
These new requirements, which include testing of the fine grade air filters with the electrostatic charge remove will allow a better assessment of the efficiency of air filters during their entire lifetime. The EN 7standard Particulate air filters for general ventilation defined the test procedure for coarse and fine dust filters. High Performance Panel Filters High performance air filters are rated to achieve efficiencies F F Fand Fto EN77 and are used to give medium to high air quality suitable for use in applications such as supply air.

The grade of filter is given a , which defines how effective the filter is to capture the contamination moving through it. Filters must be tested with an air flow rate between 0. It introduces a great innovation for fine filters (F Fand F9), which must comply with a new parameter: minimum efficiency (ME).
