The HEPA filter

The dust sucked up in the whirlwind settles directly at the bottom of the dirt cup; the HEPA (High Efficiency Particulate Air) filter traps dust mites and all organic and inorganic particles measuring over 0.3 micron (3 thousandths of a millimetre) from the outflowing air, removing them from the mattress.

Aspirac™ by AcarZero™ has a HEPA (High Efficiency Particulate Air) filter that can be washed and reused; the dust cup is easy to clean, requires no maintenance and, above all, there are no extra costs because it does not require a bag.

Utmost hygiene is guaranteed by the fact that the dirt cup is easily opened and withdrawn: it can be cleaned without any direct contact with the dust collected. The dirt cup should be emptied and cleaned and the HEPA filter washed after each use.
