HEPA filter definition

HEPA filter means high-efficiency particulate air filters that are rated to achieve a minimum initial particle-removal efficiency of 99.97 per cent using ASTM F 1471– 93 or equivalent standard;

HEPA filter means a high efficiency particulate absolute air filter capable of trapping and retaining 99.97 percent of fibers greater than 0.3 micrometers in mass median aerodynamic diameter equivalent.

HEPA filter means a high efficiency particulate aerosol filter that is at least 99.97 per cent efficient in collecting a 0.3 micrometre aerosol;

Examples of HEPA filter in a sentence

• Vacuum dust with equipment fitted with a HEPA filter and place in a closed, labeled waste container.

• All vacuums must be furnished with a HEPA filter which must remove (from the air that passes through) 99.97% of particles that have a size greater than or equal to 0.3 µm.

• Spills may be slippery.PROTECTIVE EQUIPMENT:Small Spills: Wear goggles and gloves while wiping up small spills of this product with polypad or sponge.Large Spills: Use proper protective equipment, including double nitrile or appropriate gloves, full body gown, and full-face respirator equipped with a High Efficiency Particulate (HEPA) filter.

• Vacuum must be fitted with HEPA filter to prevent release of particulates during clean-up.

• Vacuum dust with equipment fitted with a HEPA filter and place in a closed, labeled waste container.Avoid creating dusty conditions and prevent wind dispersal.
