5 Cleaning Note • Always turn the air purifier off and unplug from the electrical outlet before cleaning. • Never immerse the air purifier in water or any other liquid. • Never use abrasive, aggressive, or flammable cleaning agents such as bleach or alcohol to clean any part of the air purifier. • Only the pre-filter is washable. The air purification filter is not washable nor vacuum cleanable. • Do not attempt to clean the filters or air quality sensor with a vacuum. Cleaning the body of the air purifier Regularly clean the inside and outside of the air purifier to prevent dust from collecting. 1 Use a soft, dry cloth to clean both the interior and exterior of the air purifier. 2 The air outlet can also be cleaned with a dry, soft cloth. Cleaning the air quality sensor Clean the air quality sensor every 2 months for optimal functioning of the purifier. Note • If the air purifier is used in a dusty environment, it may need to be cleaned more often. • If the humidity level in the room is very high, condensation may develop on the air quality sensor and the air quality light may indicate a more poor air quality even though the air quality is actually good. If this occurs, clean the air quality sensor or use the air purifier on a manual speed setting. 1 Switch off the air purifier and unplug from the wall outlet. 2 Clean the air quality sensor inlet and outlet with a soft brush (fig. u). 3 Open the air quality sensor cover (fig. v). 4 Clean the air quality sensor, the dust inlet and the dust outlet with a damp cotton swab (fig. w). 5 Dry all parts thoroughly with a dry cotton swab. 6 Reattach the air quality sensor cover (fig. x). 10 EN
