HEPA Filter Media for Superior Clean Room Air Quality

Clean room filter media must provide higher levels of filtration than a typical residential HVAC system.
HEPA grade clean room air filter media 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 99.97% of all particles greater than 0.3 micrometer from the air that passes through. A filter that is qualified as HEPA is also subject to interior classifications.
Most HEPA filters consist of a rigid frame into which a filter pack (constructed by folding a continuous sheet of filter media into closely spaced pleats) is sealed.
Over the years, filter manufacturers have developed different methods and materials for maintaining the spacing of the pleats all in an effort to optimize air filter media surface area and reduce air flow resistance.
Conventional HEPA filter media can consist of glass, melt blown or electrostatically charged fibers, which are randomly oriented. Complex mechanical principles are used to achieve the filter media’s effectiveness on sub-micron particles.
Superior Felt & Filtration offers nonwoven air filter media that reaches necessary HEPA filtration levels. Our clean room filter media is available in flat sheet or pleated form.
