High Efficiency Particulate Air

But what does that really mean and how do they work.

High efficiency particulate air.

It is an acronym for high efficiency particulate air filter as officially defined by the u s. 1 micrometre 10 6 metre as specified by the united states department of energy doe and the european committee for standardization. This is known as the hepa standard. High efficiency particulate air hepa filter industrial machinery market 2020 2024.

This is a pleated filter that traps airborne particles as they pass through an air purifier. The european standard is similar to the doe. A hepa filter is a type of mechanical air filter. This type of air filter can theoretically remove at least 99 97 of dust pollen mold bacteria and any airborne particles with a size of 0 3 microns µm.

Hepa stands for high efficiency particulate air and is a filtration rating that captures microbes dust and particulates down to 0 3 micron. It works by forcing air through a fine mesh that traps harmful particles such as pollen pet.

Filters meeting the hepa standard must satisfy certain levels of efficiency.

A true hepa filter removes 99 97 of all particles that are 0 3 microns in size or larger. Common standards require that a hepa air filter must remove from the air that passes through at least 99 95 european standard or 99 97. Department of energy first termed hepa as a filtering specification for suppliers of filtration products based on how effective they were at. Hepa is a type of pleated mechanical air filter.

High efficiency particulate air system hepa system particulate air filtration system designed to capture at least 99 97 percent of fine airborne particles larger than at least 0 3 micrometre 0 00001 inch. High efficiency particulate air hepa also known as high efficiency particulate absorbing and high efficiency particulate arrestance is an efficiency standard of air filter. Using respirators and gloves can minimize these kinds of risks and hazards. High efficiency particulate air hepa filters can provide protection against the possible release of nanoparticles into the atmosphere.

Preventing inhalation skin exposure and ingestion of nanoparticles are common in the workplace. Hepa stands for high efficiency particulate air.
