Replace the filters when they become heavily soiled; each filter can last up to 5 years after opening, but in polluted environments they may need replacement sooner.
The CLEAN‑SIGN Light turns green when the air is clean, orange or red when impurities are detected, and may stay green if the unit was just plugged in before the sensor stabilizes.
Verify that the batteries are not depleted and are inserted correctly; also check for interference from fluorescent lighting.
