Replacing the air filter

Check the air filters (unit, external and room filter) regularly, depending on the amount of soiling. Select shorter change intervals if a lot of dust or dirt is produced. Change the air filter as needed. Only use original air filters.

Manufacturer recommendations:
• G4 and F7 unit filters every 3 months
• Optional external filter every 6 months
• Optional room filter every 2 months

Ordering with the AIR@home app: Go to the Ventilation/Filter/Action menu to order the right air filter directly ex factory.
• G4 replacement filter: Article no. 0093.1589
• F7 fine dust filter: Article no. 0093.1588

Call up filter service life with the AIR@home app: Go to the Ventilation/Filter menu to view the current remaining filter lives.

Changing G4 and F7 unit filters

If the two middle ventilation level LEDs flash on the operating unit, a filter change is due. Additionally, the LED lights up white on the operating unit. This function is only enabled with the status display activated.

Recommendation: Change the unit filters together.

Read the supplementary sheet Safety instructions before opening the unit.

Risk of cuts if glass parts are damaged.

Glass parts of the front covers or the operating unit are fragile. Take care when installing/removing. Observe safety instructions.

  1. APA/UPA/UPGA units: Remove the front cover.
  2. Remove the filter cover(s).
  3. Pull the unit filter out of the ventilation unit.
  4. Carefully slide the new filters into the filter shaft. Do not press in the filter (cellulose). Only press on the reinforced corners. Make sure that the air direction arrow is facing downwards.
  5. APA/UPA/UPGA units: Insert the design or glass cover at the bottom into the guide of the AP metal shell sheet or UP shell tray and engage it at the top with the locking lever. Ensure that the cover is also correctly engaged. If necessary, turn the locking lever as far as it will go.
  6. Acknowledge the filter change on the RLS G1 WS room air control.
    To do so, press the and buttons at the same time for 3 seconds, flashing stops.
    Also acknowledge a premature filter change and reset the filter change interval. If resetting prematurely, press the and buttons at the same time for 10 seconds. The LED flashes briefly. The filter change interval is reset.
    Alternatively, reset the filter change interval in the AIR@home app/AIR@home web tool.
  7. Dispose of the air filter according to local regulations.
