6. CLEANING AND MAINTENANCE

 WARNING
Before cleaning, always ensure that the mains plug of the air purifier has been properly
disconnected.

6.1 Cleaning the filter

Regular cleaning of the filter
Clean the outside of the filter with the brush attachment of a vacuum cleaner or a dry cloth.
NOTE
The three-layered filter should be changed after 4320 operating hours (see "Replacing the filter" section).
The three-layered filter cannot be washed.
If you wish to change the filter at specific personal intervals (e.g. every 6 months), there is a sticker on the
upper edge of the filter on which a date can be entered.

6.2 Cleaning the housing

Clean the housing of the air purifier with a slightly damp cloth (water or a mild cleaning solution). Do not
use solvents, other aggressive cleaning/scrubbing agents or alcohol, as these could damage the surface.

6.3 Cleaning the PM 2.5 dust sensor

Regular cleaning of the dust sensor and its associated channel (once a month) is required to ensure fault-
free operation. To do this, open the sensor flap
move coarse dust from the open channel. For even better cleaning results, you can now also run the device
at the highest setting to clear the loose dust. Close the sensor flap once cleaning is complete.
NOTE
Please note that using the device in a very dirty environment (such as a workshop with large amounts of
dust) can cause excessive soiling of the sensor. As this contamination can cause incorrect measurements,
clean the sensor more frequently in these environments.

6.4 Storage

If you do not plan to use the device for a long period of time, we recommend that you clean it and store it
in the original packaging in a dry environment, ensuring it is not weighed down by additional items.
