Filter Indicator Not Resetting After Replacement

Symptoms

• Filter life indicator still shows low percentage after installing a new filter
• Red filter alert on the display or in the app persists after replacement
• Filter was replaced but the unit behaves as if the old filter is still fitted

Likely Causes

1. Filter counter was not manually reset after replacement — it does not reset automatically
2. The new filter is not the correct part (the sensor calibration differs by filter type)
3. The filter access panel was not fully closed after installation
4. App and device are out of sync

Step-by-step Fix

1. Confirm the filter access panel on the rear of the unit is fully closed — press both side tabs firmly until they click. An open or partially closed panel prevents the filter sensor from reading correctly.
2. Reset the filter counter manually: press and hold the Filter button on the top panel for 5 seconds. The filter indicator will briefly display 100% to confirm the reset. The button is marked with a filter icon.
3. If resetting via the app: go to Devices > AirCore P2 > Filter > Reset Filter Life. Confirm the action.
4. Confirm the replacement filter is a genuine Monverta P2 filter (part MV-FLTR-P2 or MV-FLTR-P2-PLUS for the premium version). Third-party filters may not trigger the correct sensor response.
5. Cycle the power — switch the unit off, unplug, wait 10 seconds, reconnect and power on. The updated filter reading should now display.
