High-efficiency particulate arrestance (HEPA), also sometimes called high-efficiency particulate arresting or high-efficiency particulate air, is a type of air filter.
âHEPA vacuum means a vacuum cleaner which has been designed with a high efficiency particulate air (HEPA) filter as the last filtration stage.A HEPA filter is a filter that is capable of capturing particles of 0.3 microns with 99.97% efficiency.The vacuum cleaner must be designed so that all the air drawn into the machine is expelled through the HEPA filter with none of the air leaking past it.â.HEPA vacuum means a vacuum cleaner which has been designed with a high efficiency particulate air (HEPA) filter as the last filtration stage.
