To keep your Mill Silent Pro Compact Air Purifier working at its best, pay attention to the filter status indicator. The filter is designed to last up to 12 months, but this can vary depending on your home's air quality. The air purifier uses a filter status indicator, not a timer, to tell you when to change the filter. Here's what the indicator colors mean: White shows 100-20% filter life remaining, Yellow indicates 19-10% life left, Red means 9-1% life remaining, and Blinking Red means the filter needs to be replaced immediately. Check the filter change status symbol on your air purifier's display to see the current status. Replacing the filter when indicated ensures your Mill Silent Pro Compact Air Purifier continues to provide clean air.
