Steps
- Unplug the air purifier.
- Open the front cover by pulling out the top part of it.
- Press down on the top clip of the pre-filter and pull it out carefully, without a shock, so the dust does not fall off.
- Clean the pre-filter with a vacuum cleaner or with water, depending on how dirty it is.
- Remove all moisture from the pre-filter, fit it into the hook and put the front cover back.
The deodorization filter and the True HEPA filter cannot be cleaned or reused. Never wash them with water.
