There are many different Winix air purifiers. Apart from the various versions and models, they often have the same filters and they often work the same. This also applies to notifications and indicator lights, which indicate that something needs to be done or that something is going on.

When you see a red light flashing on your Winix air purifier, you’ve come to the right place. I’ll tell you why it’s blinking and how to fix it quickly and easily.

Why is a red light blinking?

A Winix air purifier is equipped with various sensors, with which the quality of the device can be monitored. When you need to take action, the Winix air purifier can indicate this. This is usually done via LED indicator lights on the top of the air purifier.

When a red light flashes, the following may be the case:

  • The filters are dirty and need to be cleaned
  • The filters are not placed properly or are not recognized
  • The filters need to be replaced

Below the red light is an icon of a filter that needs to be replaced. That looks like this:

Light stays on, even after replacing filters

It is true that the light continues to flash red after replacing the filters. You still have to reset it, which indicates that new filters have been placed in the Winix air purifier. You can do this with an elongated and thin object, such as a paper clip. You will see a small hole next to the red flashing light. Press the button for 5 seconds to reset the air purifier.

If the light still stays on, you may need to clean the pre-filter thoroughly. Although the pre-filter does not need to be replaced, it is necessary to clean it regularly. This will prevent blockages. See here how to clean a Winix filter.
