Cleaning and maintenance

• The outside plastic surfaces can be wiped off with a soft lint-free cloth lightly moistened with water as part of normal household cleaning.
• Be careful not to expose the filter to fluids and/or to any physical damage.
• Check at least weekly that the Air4 air supply nozzle is undamaged.

Filter change

To maintain the intended effect of the Air4 it is very important that the filter is changed every 6th month. Your Air4 will indicate when it is time to change filters. If the filter is not changed when indicated, the Air4 will stop after a while and cannot be started until a new filter is installed. The remaining time before the filter must be changed is shown in the Filter Screen.

Airborne particles in the environment are concentrated in the filter; thus, persons suffering from allergy or asthma should avoid changing the filters by themselves due to the risk of allergen and particle exposure.
