Installation guide - Replacing a filter
General guidance for this part type - always follow your device manual- No tools required in most cases
- Do not wash a filter unless it is marked washable; wet HEPA media stops filtering.
- If the filter does not sit flush, stop and recheck the model on this page.
- 1Switch off and unplug. Power the device down and unplug it.
- 2Open the filter compartment. It is usually behind a front or back cover, or inside the dustbin on vacuums. Your manual shows the exact spot.
- 3Remove the old filter. Note how it sat, especially any airflow arrow or rubber seal facing the motor. Tap dust off into a bag outdoors.
- 4Fit the new filter. Take off all plastic wrap, seat it the same way round until it sits flush with its seal fully in contact, and never force it.
- 5Close and test. Close the cover, run the device and check for normal sound and airflow. Reset the filter reminder if your device has one.
