FILTERS - type of filter may vary from different models

On these machines there are two different filters; one pre-filter before the vacuum motor and one exhaust filter.

There are two different types of exhaust filters available to these machines, HEPA-filter and a standard exhaust filter. The HEPA-filter (High Efficiency Particulate Air filter) offers better filtration capacity then the standard exhaust filter. The exhaust filters catches any dirt that may escape from the dust bag, or motor pre filter. Replace the filter every fourth time that the dust bag is changed (more often in very dusty applications). The exhaust filters are located at the front side of the machine just above the brush base.

The HEPA filter can not be cleaned or washed clean. When the HEPA-filter is clogged it must be replaced.
