In the air filtration industry, there are numerous standards for
classifying, identifying, and evaluating the various performance
characteristics of air filters.
In the United States, the organization responsible for setting
these standards is ASHRAE. Since 1968, ASHRAE has released a series
of test standards for air filters, which have been recognized by
the American National Standards Institute (ANSI) as the benchmark
for filter performance classification.
H13 HEPA,0.3μm particles Purification efficiency>99.95% F9
Medium effect filter, 1μmparticles Purification efficiency>95%
G4 Coarse filter, 10μm particles Purification efficiency>90%
At the same time, to support the selection of energy-efficient air
filters, EUROVENT (the European Association of Manufacturers of
Refrigeration, Air Conditioning and Heat Pumping Equipment)
developed the "Eurovent 4/11" guidelines in 2012 and upgraded it in
2015. The guideline is based on the EN 779:2012 standard for energy
consumption calculation and is classified according to energy
consumption. This tool enables us to select high-efficiency filters
based on the standard and ensure lower energy consumption,
providing the best solution for users.
