HEPA, which stands for High Efficiency Particulate Air, is a designation used to describe filters that are able to trap 99.97 percent of particles that are 0.3 microns.
In simple terms HEPA filters trap air contaminants that travel in the air in a web of different fibres.
Particles range in size from ultra-microscopic to fully visible to the naked eye.
Particles themselves are measured in microns (which are one millionth of a metre). Consider that humans can’t see anything smaller than 10 microns, which gives you a better understanding of the size of a micron or less than a micron.
The filter can be rinsed and dried and reused before having to be replaced.
Note:
This HEPA filter is only designed for the DEEBOT X2 COMBO's handheld vacuum cleaner.
