KIT: HEPA-filter and antistatic prefilter

The HEPA-filter filters the vacuumed air before the ejection. The filter retains 99.97% of dust, particles and allergens of Ø 3 microns. M class.

The Pre-filter, attached to the HEPA filter, captures the majority of the dust in
order not to occlude the filter and it makes easier the cleaning operations of
the filters.
