suction.

Replacing the HEPA filter and activated carbon filter
1.
The two filters should be replaced after approximately 3 months. However, the time of replace-
ment depends on how the device is used. It is recommended to replace the two filters at the
same time to keep the device working at its best.
2. Signs that indicate that the filters need to be replaced include the following:
a. HEPA filter has turned yellow or brown due to the absorption of a lot of particles and
smoke.
b. The filter performance has lowered because there are many particles in the filter.
c. The extraction performance has lowered because the filter is clogged.
3. To replace the HEPA filter, unlock the top cover of the device and pull out the old HEPA filter.
Unpack the new HEPA filter and then install it. Make sure that it is in the centre of the unit and
note the direction of the arrows.
4. Lock the top cover again to prevent air leakage and suction performance degradation.
5. To replace the activated carbon filter, pull out the old filter by the two white tabs. Unpack the
new carbon filter, then slide it into the unit.
