How to Reset Levoit Air Purifier Red Light? (Easy Tutorials)

If you’re a Levoit air purifier owner, you may have encountered a situation where the check filter light of your device has turned red. This red light is an important indicator that alerts you when it’s time to change the filter or if there’s some other issue with the purifier’s air filter. Fortunately, you can easily reset the red-light indicator on your Levoit air purifier in just a few steps.

Today, we’ll guide you through the process of resetting the red light on your air purifier. We’ll also provide some troubleshooting tips to ensure your device runs smoothly and efficiently. So, let’s dive in!

Why is the Red Light On?

The most common reason for the red light on your Levoit air purifier to turn on is the condition of its filter. Over time, the air filter becomes clogged with pollutants, reducing its air purifying effectiveness. The red light on your air purifier indicates that the filter has reached the end of its lifespan and requires replacement.

In case you have replaced the filter recently, but the red light is still on, there could be a chance that the filter wasn’t installed correctly. If the filter isn’t correctly installed, it won’t be able to purify the air effectively, and the red light will remain on. 

Lastly, excessive debris in the filter compartment can also cause the red light to turn on in your Levoit air purifier. If the filter compartment is clogged with dust, hair, or other debris, the air won’t be able to circulate properly through the filter, which can lead to reduced air quality and the red light turning on.
