The filter inside your Winix air purifier is an important part of how the machine works. In order for the air purifier to work at its best, the filter needs to be replaced regularly.

Keep reading to learn more about how to do this and then how to reset the Winix air purifier red light.

Winix Air Purifier Check Filter Indicator Red Light Blinking

The ‘Check Filter’ indicator light looks like a 3D square with an arrow pointing left and right. When this light on your Winix air purifier turns red and starts blinking or flashing, it is time to replace your filter.

In addition to cleaning pre-filter every 14 days, the filter should be replaced approximately every 12 months. The Winix air purifier red light may turn on before 12 months depending on the level of use and the air quality of the environment it is in. The Winix HEPA filter cannot be washed so you will need a new one when the red light turns on. Always use a genuine Winix air filter replacement for best results.
