Replacement Filter Indicator

Unlike many filter life indicators, Winix's True Life Filter Indicator measures ACTUAL usage when determining when it's time to change the filter.

Actual Usage

You no longer have to worry whether you're getting the most out of your filter.  Using actual fan speed and usage, the True Life Filter Indicator determines when you've reached the point where you may begin to see diminished performance from your air cleaner.

That means you no longer replace the filter before it's necessary and you are alerted to when you and your family may not be getting the performance promised to you by Winix.
