LG CLEAN FILTER status display

What it means

Clean Filter is a maintenance reminder based on recorded operating hours, not a sensor proving the filter is dirty. LG says the message can appear independently of actual filter condition.

Urgency

Likely causes

Homeowner fix

Check the indoor filter for dust, clean it according to the owner's manual, and reinstall it dry. Depending on your remote type, the message may clear automatically after more operation or may need the remote's filter-display release/reset steps.

When to call a pro

Call for service if the filter is clean and seated but airflow is weak, the message will not reset, or another CH code appears.

Repair vs replace

This is routine maintenance. Replacement is only needed if the user-removable filter is damaged or missing.
