Basics of...Air Filters
Type of FilterDescription
Panel / CleanroomCleanroom filter modules and replacement panels designed for ultimate filtration.
HEPADesigned to provide the highest levels of air cleanliness for filtration. Individually tested (99.97 / 99.99995) and certified. HEPA filters have a strong mechanical efficiency on virus such as influenza including the most recent forms of avian flu.
Medium and High Efficiency RigidExtended media, rigid filters designed fur use in most commercial or industrial HVAC systems where medium to high efficiency filtration is required.
BagDesigned for use in most commercial or industrial HVAC systems where medium to high efficiency filtration is required. Made in glass and synthetic media.
Gas Phase and Odor ControlDesigned to bring both types of odor molecules, acid or base, into a more neutral, PH balanced, odor free state.
Pleated PanelDesigned to operate in most every type of installation (heating, air conditioning, or ventilating systems), suitable for variable air volume systems. Meets MERV 8-11 requirements per ASHRAE 52.2 Standards.
Antimicrobial TreatedAdded layer of Antimicrobial protection on filter helps prevent growth of odor causing bacteria (Lysol Brand).
Paint BoothWide variety of links, cubes, pads, rolls and liner sheets for any paint booth.
Grease / MetalHeavy-duty metal washable filters suitable for residential and commercial use.
Air Filter Media and Auto Rolls Manufactured in selected widths, prepared in roll lengths that make manageable roll sizes. In most cases, a single cut across the roll will produce a ready- to-install filter pad. Selection includes polyurethane foam, neoprene coated natural fiber, spun glass and polyester fiber rolls.
Electronic Air CleanersDesigned to catch smaller particles without creating high airflow restriction.
DisposableDesigned for use in any application where disposable panel filters are recommended. They can be replied upon for superior performance since they are specifically designed for heavy workloads.

Glossary of Terms

ASHRAE:
American Society of Heating, Refrigerating and Air-Conditioning Engineers
DOP:
Dioctiphthalate (diethylhexylohosphate), an oily liquid used in an aerosol form as a challenge for efficiency and leak testing HEPA filters.
HEPA:
High Efficiency Particulate, Air (filter)
Micron:
One millionth of a meter. A micron is more correctly known as a micrometer.
Pressure Drop:
The resistance of a device to the flow of a fluid through it. The pressure drop of a filter is a measure of its resistance to airflow through it.Resistance is measured in inches w.g. in the Inch-Pound system of measurement. It is measured in Pascals in the SI system.
Resistance:
See Pressure Drop
ULPA:
Ultra Low Penetration, Air (filters). Filters in this category typically have efficiencies of 99.999% on a 0.3 micron DOP particles.

Compiled and averaged from manufacturer′s data. Efficiency per ASHRAE Standards 52 Test methods. Curves and approximations only for general guidance. Values from them must not be used to specify air filters, since a generally recognized test standard does not exist. Graphs from Equipment Handbook, Air Cleaners for Particulate Contaminants.
