Winix Light Indicators: What is the Meaning of a Red Light?

Every Winix air purifier features various indicators and lights, each representing different functions or types of information. The presence of red color anywhere on the device can sometimes be confusing and often signals an issue that needs attention.

However, there’s no need for an alarm if a red light appears on your Winix. Each indicator has a specific meaning. Typically, the small red light indicates it’s time to replace your air purifier’s filters.

Still, some other indicators may also light up in red and potentially lead to confusion. That’s why I’m writing this article, and will clarify these indicators and their meanings.

In short: the primary purpose of a filter reset red light indicator is to remind you of a time for replacing the filter. In addition, there is also the air quality indicator, which may turn red depending on the pollution level in your place.

Winix Filter Reset Indicator (Red Light)

The filter reset indicator on your Winix air purifier is a small LED light located on the control panel. This indicator lights up in red, but only when it’s time to replace the filter.

For those who prefer a visual explanation, refer to the image below, on which I marked the location of the filter reset indicator.

This indicator will light in red approximately every 12 months; the same for every Winix air purifier. Upon showing, it signals the need to replace your air purifier’s filters, usually a True HEPA and an activated carbon filter.

Some Winix models use a fibrous carbon filter that needs to be replaced every 3 months. Unfortunately, these carbon filters have no filter reset indicator, so you must manually track their wear.

After replacing the filter, the filter reset indicator needs to be reset. This turns off the red light and restarts the indicator’s timer. To reset it, press and hold the filter reset button using a small object, like a paper clip, for about 5 seconds.

Winix Air Quality Indicator

Now, let’s talk about other LED indicators of the Winix air purifier. The most important one is the air quality indicator, which is built into every Winix model I have tested or researched so far.

This indicator provides real-time information about the air quality in your room by displaying various colors, each representing different air conditions. For instance, red indicates very poor air quality, while blue signifies good air quality.

It’s necessary to note that not all air quality indicators on Winix models are identical. For a clear understanding, please refer to the table below, which explains the meanings of the different colors specific to different Winix models.

Winix A231; 5500-2; 9800; 5300-2; AM80; AM90; D360; 6300-2; Good: Blue
Fair: Amber
Poor: Red

The most important thing is not to get confused, as the air quality indicator is informative and doesn’t involve any action similar to when the filter reset indicator lights up. Therefore, if the air quality indicator turns red, it does not imply a need to replace the filter. Instead, it suggests adjusting the fan speed to its maximum setting for improved air quality.
