  • Is the power supply to the wall socket working properly?

Service & Care

Air4 helps improve your quality of life by creating an allergen and particle free breathing zone at home in your bedroom. Here is how to take care of your Air4 to ensure it works optimally to alleviate your symptoms.

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.
