Particulate Filters

Custom Filters for Capturing Harmful Particulates

Particulate filters are recommended in applications where dust and powders can pose a threat to the user and/or environment. Our application specialists will help you select the appropriate ASHRAE filter (high efficiency), HEPA filter (higher efficiency), or ULPA filter (highest efficiency) for your requirements.

ASHRAE

High Efficiency

An ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) filter refers to a fibrous filter that is efficient up to 95% on particles as small as 0.5 microns. This type of filter is very similar to the HEPA filter but does not have as high an efficiency rating. The MERV efficiency rating is 15 for an ASHRAE filter, and it can be used to capture bacteria, pollen, spores, and other harmful particulates.

SCF ASHRAE Filter Features
  • 100% Fire Retardant
  • Polyalphaolefin (PAO) Batch Tested (a test gas with an equal mean distribution of .3 microns dispersed through an aerosol generator)
  • Choice of foam in place gasket or unabridged, gasket closed cell neoprene
  • Multi-level quality assurance
  • Handcrafted with specialty purpose fiberglass material
  • Up to 95% efficiency on particles down to 0.5 microns in size
  • MERV 15

Up to 95% Efficiency

Down to 0.5 microns

HEPA

Higher Efficiency

In accordance with standards set by the U.S. Department of Energy, high efficiency particulate air (HEPA) filters must meet an efficiency rating of up to 99.97%, on particles as small as 0.3 microns. Some HEPA filters marketed for consumers do not meet these standards and are not true HEPA filters with the same capability or efficiency. True HEPA filters have a MERV rating of 17 and provide excellent filtration for bacteria, lung damaging dust, spores, pollen, pulverized coal, and metallurgical dust and fumes.

HEPA filters were first invented during World War II to capture radioactive particles released from atomic bombs. However, the certification standard was not implemented until 1983. Today, HEPA filters must undergo strict testing to ensure accurate efficiency rating and classification.

SCF HEPA Filter Features
  • 100% Fire Retardant
  • Polyalphaolefin PAO Batch Tested (a test gas with an equal mean distribution of .3 microns distrusted through an aerosol generator)
  • Choice of foam in place gasket or unabridged, gasket closed cell neoprene
  • Multi-level quality assurance
  • Hand crafted with specialty purpose fiberglass material
  • Up to 99.97% efficiency on particles down to 0.3 microns in size.
  • MERV 17

Up to 99.97% Efficiency

Down to 0.3 microns

ULPA

Highest Efficiency

Ultra low particulate air (ULPA) filters have efficiency of up to 99.9995% on particles as small as 0.12 microns. ULPA filters have a MERV rating of 20 and are the highest-quality filters available. ULPA filters provide better filtration for tobacco smoke, oil smoke, insecticide dust, and carbon dust, and they even capture some viruses.

SCF ULPA Filter Features
  • 100% Fire Retardant
  • Polyalphaolefin (PAO) Batch Tested (a test gas with an equal mean distribution of .3 microns dispersed through an aerosol generator)
  • Choice of foam in place gasket or unabridged, gasket closed cell neoprene
  • Multi-level quality assurance
  • Handcrafted with specialty purpose fiberglass material
  • Up to 99.97% efficiency on particles down to 0.5 microns in size
  • MERV 20

Up to 99.99% Efficiency

Down to 0.12 microns
