Why Levoit Air Purifier Blinking Red Light? (4 Ways To Fix)

If your Levoit Air Purifier’s red light is blinking, it means the filter is really dirty, damaged, or there’s a temporary problem inside.

It’s not a major problem, but if you ignore it and keep using the purifier, you might harm it.

In this article, I’ll explain:

  • What the blinking red light on a Levoit Air Purifier means
  • How to fix this issue?

Let’s dive in…

So how to solve this issue?

  • First, reset the purifier by pressing and holding the “check filter” indicator button for approximately three seconds.
  • If the red light still flashes, clean the filter.


Here are the detailed guidelines:

Step 1) Clean the Air purifier filter

Clean your Airpurifier filter

According to the Times of India, an Air purifier can stop working or start to misbehave incorrectly due to a clogged or broken filter.

It could also stop working for other reasons, but a broken or clogged filter is the main culprit.

So, before you do anything else, first try cleaning the filter.

To clean your Levoit Air purifier filter, follow the below steps.

⇒ Turn off and unplug your device

Turn off and unplug your levoit air purifier

Before cleaning the filter, unplug your device from the wall outlet or charging station.

Also, turn off your Purifier completely.

This will help speed up the process and make your job safer, lowering the risk of an electric shock.

⇒ Pull out the filter from the Purifier

After unplugging and turning off the device, flip the Air purifier upside down.

Turn the cover plate counterclockwise and pull out the filter from the Purifier.

Put your Air purifier on the carpet rather than on the open floor. This will prevent scratching up the top of the device.

⇒ Clean the filter

You will see a lot of dust accumulated in the filter. So to clean it

  • First, take your vacuum cleaner and turn it on.
  • Then start vacuuming the filter.
  • Blow away as much dirt as you can.

Once you have cleaned the filter, reinstall it in its place and lock the bottom. That’s it!

Don’t use any water or other liquid to clean the filter, as it will damage your device’s filter. Only use a vacuum or other dirt blower machine to remove dust particles.

Step 2) Power cycle your Levoit Air Purifier

You have just cleaned the filter or even replaced the old one with a new one, but your Levoit Air purifier still displays the red light! Right?

OK relax!

First of all, you don’t need to worry about it. It’s just a software glitch in your device and can be easily fixed through a reset.

To reset your Levoit Air purifier, press and hold the “check filter” indicator button for about three seconds. After three seconds, let the button go, and hopefully, the red light issue will be solved!

Step 3) Let the device cool down

This issue can also happen when your air purifier gets too hot.

Overheating is such a threat that it might affect not only the functionality of your air purifier but also cause irreparable damage.

Air purifiers can become overheated by several factors, including a faulty power source, malfunctioning internal components, and filter obstruction.

However, not all models meet these criteria.

Most of them include a built-in safety feature that activates if your Purifier runs too long or gets too hot.

However, if the “clean filter” indicator is still flashing after resetting the device, check whether the machine is overheated or not. Let the device cool down for at least 60 minutes if it is.

After that, turn on your and your problem should be solved!

Step 4) Replace the Filter

Replace your Air purifier Filter

When was the last time you changed the filter on your Levoit Air purifier? Did you change the filter within the last six months?

I am sure you haven’t changed its filter in the last six months.

But did you know that Levoit suggests that users should change the filter every 5-6 months?

According to Levoit, you should be serious about the filter and must replace the filter at least two times a year to get optimal functionality.

So as a last option, try replacing the filter with a new one. You can buy a new replacement filter from this link at Amazon.
