Now, let’s get started to solve your possible problems in detail!

#1. Air pollution

The air quality indicator is mainly designed to show you the current air condition. Thus, the air quality indicator starts flashing red light due to the high level of air pollutants.

Different contaminants can pollute the air in your home, including dust, pollen, pet dander, and many other airborne particles and allergens. As a result, the air purifier informs you about the bad air condition.

In this case, all that you should do is just improve the air quality. In other words, let the Winix air purifier completely improve your air quality!

To clean your air from excess contaminants, set the air purifier at its maximum speed and let it work until amber and then a blue light appears on the air quality indicator.

After purifying all the air, check the filters as they can require extra cleaning.

To prevent air pollutant congestion, clean your house more frequently.

#2. Filter clogging

The second most common cause of red light flashing can be hidden in the Winix air purifier filters. If the contaminants gathered from the home air are not removed frequently, they clog the air purifier filters. Thus, the LED light red indicator displays the critical level of pollution due to the dirty air purifier filtering system.

Step #1. Deactivate and disconnect the Winix air purifier.

Step #2. Detach the air purifier’s front panel to see the filters.

Step #3. Take the pre-filter out of the air purifier.

Step #4. Examine the filters thoroughly. If you can see that your old filter is extremely dirty, the best thought is to replace it with a new one. However, if they are moderately dirty, you can simply clean them thoroughly and reinstall them in the air purifier.

Step #5. Detach the filters from the air purifier. With the help of a soft brush, sweep most of the dirt and debris from the filters before washing them.

Step #6. Wash the filters carefully with the help of clean warm water and mild dish soap. Be sure to get rid of all the mess accumulated inside!

Step #7. Wipe the filters with a clean paper towel, and let them air dry completely. Be sure that they are fully dry when reinstalling them into the air purifier!

Step #8. Following the arrows’ directions of the air purifier, reinstall the clean filters into the machine. Insert the pre-filter as well.

Step #9. Reinstall the front panel and test if the air purifier works correctly.

After the new filters’ installation, the red light problem can persist. In this case, it is enough to reset the Winix air purifier.

In case the red light continues flashing after this step, the issue can be hidden in the pre-filter that is also clogged. There is no need to replace this part of the Winix air purifier, but never forget to clean it frequently and thoroughly to prevent extra troubles.

In case the blinking light problem persists, give the pre-filter of the air purifier a proper cleaning.

The best rule of thumb is to check and clean the filters and pre-filters in your air purifier every several months to prevent blockages.

#3. Dirty sensors

Another possible cause of Winix air purifier red light issues is dirty sensors that don’t work properly. Along with defining the air quality, these sensors are responsible for the fan speed adjusting according to the readings. So, if the sensors are covered with dust and debris, the readings will be wrong and make your Winix air purifier run poorly.

Step #2. With the help of a soft brush, clean the sensors thoroughly to dispose of any mess accumulated on them.

In case the dirty sensor was the culprit of the red light issue, your Winix air purifier will run normally. When the red light flashes after cleaning, look for other reasons.

#4. Filter inserting issues

Sometimes the Winix air purifier red light issue can be a sign of a wrongly inserted filter. Thus, Winix air purifier tells you about the error until you reinstall the filter properly.

Having a True HEPA filter, the Winix air purifier also has inner arrows that indicate the replacement process. Follow the arrows’ directions to replace the True HEPA filter properly.
