High Efficiency Particulate Air Hepa Filters
High efficiency particulate air hepa filters must meet the efficiency rating of 99 97 on particles as small as 0 3 microns set by the us department of energy in order to be a true hepa filter 5 some hepa filters marketed for consumers do not meet these standards and are not true hepa filters with the same capability or efficiency.

Hepa is an acronym that stands for high efficiency particulate air. High efficiency particulate air hepa also known as high efficiency particulate absorbing and high efficiency particulate arrestance is an efficiency standard of air filter. A true hepa filter removes 99 97 of all particles that are 0 3 microns in size or larger.
This is known as the hepa standard. It is an acronym for high efficiency particulate air filter as officially defined by the u s. Jinpus air purifier small air cleaner for home with hepa filter 2020 upgraded low noise portable air purifiers gl 2103 white 4 3 out of 5 stars 1 428 39 99 39. The recent advances in nanomaterials have driven the study on the use of nanofibers in combination with materials such as textiles or fiberglass.
It works by forcing air through a fine mesh that traps harmful particles such as pollen pet. This is a pleated filter that traps airborne particles as they pass through an air purifier. 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. Bosch cabin air filters are designed and tested to meet high efficiency particulate air hepa standards.
What is a hepa filter. Hepa stands for high efficiency particulate air. A hepa filter is a type of mechanical air filter. Hepa is a type of pleated 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.
