The Core Mini-P Check Filter light is a service reminder whose timing depends on use and air quality. Confirm purifier model LAP-C161-WUS and genuine filter reference LRF-C161-WUS before opening the base. With power disconnected, remove the used filter carefully, take every piece of plastic off the new one, seat it correctly and close the base. The same Control Button changes fan speed and resets the reminder, so follow the exact action shown in the Core Mini-P manual rather than guessing with repeated presses. Keep the circular intake clear after reassembly.
Models covered
Safety first
- Never run the purifier with the filter wrapped in plastic, and disconnect power before opening the base.
What the symptom may indicate
Checks in the right order
- Match both references
Confirm purifier LAP-C161-WUS and replacement filter LRF-C161-WUS before opening the unit.
- Replace without spreading dust
Switch off, unplug, open the base as documented and lift out the used filter carefully. Remove all plastic from the new filter before seating it.
- Close and place correctly
Secure the base, stand the purifier on a stable surface and keep the 360-degree intake unobstructed.
- Reset with the documented control
Reconnect power and use the Control Button reset shown in the Core Mini-P manual. Avoid repeated short presses because the same button changes fan speed.
Stop and get qualified help when
- Do not force a filter whose reference or dimensions differ from LRF-C161-WUS for this exact model.
- Stop for a damaged adapter, liquid ingress, unusual heat or a burning smell and contact Levoit.
