Regular maintenance
• To extend the lifespan of your filters and to ensure optimal functioning of
your air purifier, it is advised to periodically vacuum the pre-filter (first grid).
The interior of the unit and the grids should be cleaned at regular intervals.
• To keep the particle sensor working properly, clean it regularly with a cotton
cloth.
Cleaning the particle detector
The detector's room should be cleaned from time to time with a cotton cloth, first
humid and then dry, to absorb the remaining moisture. Around every two months
depending on your environment.
Filter replacement
The filters should be replaced when the change indicator on the control panel flashes.
This will depend on your environment and usage frequency, usually within 6 to 12
months.
The filter set is made of a single block containing the HEPA filter, the activated carbon
filter, and the photocatalytic grid. Changing it is therefore quite easy.
