Device that removes from the air tiny particles that can irritate the nasal and breathing passages.
High Efficiency Particulate Air filter, which filters out 99.97% of contaminants such as asbestos, lead or mold spores.
High Efficiency Particulate Arrestor. Cartridge style exhaust filter that traps particles in the .3-micron range. Typical allergens are in the .5-micron range. Good for allergies and low dust emissions.
A High Efficiency Particulate Air filter that can be used with a vacuum cleaner to decrease exposure to dust and animal dander. (none) (none) (none) (none)
Filtration with high efficiency for particles in the air.
High Efficiency Particulate Air filters that have been tested to assure removal of 99.9% of particles 0.3 µm in size
High-Efficiency Particulate Air filter A specially constructed filter membrane that allows a high volume of air flow and stops small particles of some pre-determined size from passing through.
igh- fficiency articulate ir filter.
High Efficiency Particulate Air filter. A disposable, extended-pleated, dry-type filter with (1) a rigid casing enclosing the full depth of the pleats; (2) a minimum particle removal efficiency of 99.97% for thermally generated monodisperse DOP smoke particles with a diameter of 0.3 µm (micrometer); and (3) a maximum pressure drop of 1 in. w.g. when clean and operated at its rated airflow capacity.
a great filter to use that will rid your air of any harmful substances
a great way to get rid of allergy problems because of its totally closed-off filtration system
a high-efficiency particulate-arresting filter, capable of removing most of the particles that can cause health concerns
a special filter that captures the very small particles of lead dust
a useful adjunct in allergen reduction/avoidance
HEPA filter stands for High Efficiency Particulate Air filter. Such a filter will be at least 99.97% efficient at removing all particles in the air down to a size of tenths of a micrometre.
(high efficiency particulate air filter) A filter capable of screening out particles larger than 0.3 µm. HEPA filters are used in laminar air flow cabinets (hoods) for sterile transfer work. See prefilter.
(High-efficiency particle arrester) A special filter that can be integrated into central heating and air-conditioning systems to reduce airborne-particles associated with allergies, particularly allergies to pollen, animals, mites and mold. Portable HEPA air purifiers have been shown to reduce household levels of mites or animal allergens.
High efficiency particulate air filter designed to remove 99.9 percent of particles as small as 0.3 micrometer in diameter from a flowing air stream.
A high-efficiency particulate air (HEPA) filter composed of pleats of filter medium separated by rigid sheets of corrugated paper or aluminum foil that direct the flow of air forced through the filter in a uniform parallel flow. HEPA filters remove 99.97% pf all air particles 0.3 mm or larger. When HEPA filters are used as a component of a horizontal or vertical laminar airflow hood, an environment can be created consistent with standards for a Class 8 (Class 100,00) clean room.
a type of air filter that protects against airborne transmission of tuberculosis.
A specialized filter that is capable of removing 99.97% of particles 0.3um diameter and that may assist in controlling the transmission of M.tuberculosis. Filters may be used in ventilation systems to remove particles from the air or in personal respirators to filter air before it is inhaled by the person wearing the respirator. The use of HEPA filters in ventilation systems requires expertise in installation and maintenance.
High efficiency particulate air filter with minimum 0.3 micron particle retaining efficiency of 99.97 percent.
High efficiency particulate air filter. Available in different performance classifications ranging from 95 to 99.99% efficiency for 0.3 um DOP aerosol
A disposable, extended medium, dry type filter with a particle removal efficiency of no less than 99.97 percent for 0.3u particles.
HEPA stands for High Efficiency Particulate Air and is an officially recognized standard throughout the filtration industry. It is a rating indicating that the filter is capable of retaining all particles as small as 0.3 microns in size at an efficiency rate of 99.97 percent.
High Efficiency Particulate Air filter. An extended surface mechanical filter having a minimum particle removal efficiency of 99.97% for all particles of 0.3 micron diameter with higher efficiency for both larger and smaller particles.
An abbreviation for high efficiency particulate arrestor. These filters are used when a high degree of filtration is desired or required.
HEPA stands for High Efficiency Particulate Air. HEPA filters were developed during World War Two as a safety device for the Manhattan Project, the American effort to develop nuclear weapons. HEPA filters use glass fibre as a filter and can clean 99.7 per cent of particles above 0.3 microns in diameter. Though brittle, these filters are now widely used in a variety of filtration devices, and are widely considered to be the best air filter available to the public.
Capable of removing at least 99.97% by count of a standard 0.3 micron challenge particulate (DOP test).
A type of air filter capable of filtering out micro-organisms from the air passing through it. Modern sterilizers use HEPA filters to prevent contamination during their drying cycle. The presence of a HEPA filter in a piercing room or operating theatre will reduce the risk of contamination of a piercing.
