A particulate air filter is a device composed of fibrous materials which removes solid particulates such as dust, pollen, mold, and bacteria from theair.
European Normalisation standards recognise the following filter classes:

Usage	Class	Performance	Particulate size approaching 100% retention
Primary filters	G1	65%	>5 Âµm
	G2	65–80%	>5 Âµm
	G3	80–90%	>5 Âµm
	G4	90%–	>5 Âµm
Secondary filters	M5	40–60%	>5 Âµm
	M6	60–80%	>2 Âµm
	M7	80–90%	>2 Âµm
	F8	90–95%	>1 Âµm
	F9	95%–	>1 Âµm
Semi HEPA	E10	85%	>1 Âµm
	E11	95%	>0.5 Âµm
	E12	99.5%	>0.5 Âµm
HEPA	H13	99.95%	>0.3 Âµm
	H14	99.995%	>0.3 Âµm
ULPA	U15	99.9995%	>0.3 Âµm
	U16	99.99995%	>0.3 Âµm
	U17	99.999995%	>0.3 Âµm

HEPA(High-Efficiency Particulate Air) Filter

High-efficiency particulate air or HEPA is a type of air filter. Filters meeting the HEPA standard have many applications, including use in medical facilities, automobiles, aircraft and homes. The filter must satisfy certain standards of efficiency such as those set by the United States Department of Energy (DOE). To qualify as HEPA by US government standards, an air filter must remove (from the air that passes through) 99.97% of 0.3 µm particles. This size constitutes the Most Penetrating Particle Size (MPPS), which is the most difficult size of particle to filter. Smaller and larger particles are filtered at even greater efficiency. A filter that is qualified as HEPA is also subject to interior classifications.

ULPA(Ultra Low Penetration Air) Filter

An ULPA filter can remove from the air at least 99.999% of dust, pollen, mold, bacteria and any airborne particles with a size of 100 nanometres (0.1 µm) or larger.
It is mainly used as a final filter in clear room filtration or where high air cleaning efficiency is required.
