• The NanoCaptur filter contains translucent granules which change color according to the formaldehyde absorption
rate. Refer to the color chart on the inside of the panel or the filter itself to establish the filter saturation rate. Once the
saturation rate has reached its maximum, the filter must be replaced. You have to check the filter saturation rate every
six months.
• The pre-filter can be re-used: remove the dust using a vacuum cleaner or wash with water.
CAUTION:
The appliance's efficiency can be reduced if the pre-filter is not cleaned regularly.
Never use a pre-filter that is still damp.
The pre-filter is the only filter which can be re-used and washed with water. The HEPA, NanoCaptur and active
carbon filters cannot be cleaned and re-used. Never wash with water.
