Vacuum cleaners simply labeled "HEPA" may have a HEPA filter, but not all air necessarily passes through it. Finally, vacuum cleaner filters marketed as "HEPA-like" will typically use a filter of a similar construction to HEPA, but without the filtering efficiency.
What is a HEPA filter? HEPA is a type of pleated mechanical air filter that is common in portable air cleaners, also known as air purifiers. It is an acronym for "high efficiency particulate air" filter, as officially defined by the U.S. Department of Energy.
What is a HEPA filter? HEPA (High Efficiency Particulate Air) is an air filter efficiency standard – a certification of a filter’s performance. HEPA is defined as a filter that captures 99.97 per cent of particles down to 0.3 microns and is tested using a standard by an organisation called the IEST.
A HEPA filter is a pleated mechanical high efficiency particulate air filter that captures at least 99.97 percent of 0.3 micron particles. In healthcare and other controlled spaces, HEPA is used where very high particle removal is required.
HEPA filters are high efficiency filters that typically capture over 99.5% of all particulate pollution. They’re made from either plastic (PP+PET) or fiberglass, and can capture things like pollen, viruses, bacteria, mold and PM2.5.
