Why Is There A Red Light On My Levoit Air Purifier?

Air purifiers are extraordinarily helpful devices, but it can be something of a challenge to decipher their mechanisms.

For example, what is the red light on your Levoit air purifier? Why does it always seem to be on?

How do you know which issue your Levoit air purifier is facing? How can you get your air purifier back into working condition and keep your air healthy and breathable?

We love our air purifiers, but seeing that red light was confusing and a little worrying at first.

Thankfully, it’s a lot less concerning than we initially thought.

Read on to learn everything you need to know about turning off the red light on your Levoit air purifier.


Your Air Purifier May Work Perfectly

If you noticed a red light on your Levoit air purifier, you don’t need to immediately assume the worst.

Your device may be working exactly as its manufacturers intended!

Typically, when a red light comes on in your Levoit air purifier, it means that the device has detected unhealthy quantities of air pollutants.

If you have set the device to its automatic function, the air purifier will activate and collect pollutants, bringing your air quality back up to a healthy level.

However, if you have not set your air purifier to automatic, it will not activate on its own.

It detects the pollutants but cannot do anything about them. 

Try activating your air filter by hand.

Soon, the red light should turn yellow and then green as it cleans your air.


Why Is There A Red Light On My Levoit Air Purifier?


Clean Or Replace Your Air Filter

If the red light on your Levoit air purifier will not go away, it could mean that your device has taken in as many air pollutants as it can carry.

No need to worry; you don’t have to buy a new unit just yet.

You can spend some time replacing or cleaning your air filter to get your air purifier back into a perfectly-working condition and turn off that annoying red light.

To clean your HEPA air filter, simply open your air purifier and extract the filter.

Use a vacuum or a dry cloth to remove dust and detritus from the air filter before replacing it.

Ideally, you should clean your air filter around once a month.

If it gets to the point that the red light is flashing, then your filter has taken on soo many pollutants that it is overladen and functionally useless.

However, your air filter may have suffered damages that require more care than a simple cleaning can handle.

What can you do in these situations?


How To Replace Your Air Filter

Replacing your air filter is remarkably similar to cleaning it.

Simply open your Levoit air purifier and remove the old air filter, putting your new one in its place.

If you want to get a bit more involved, try vacuuming or cleaning the inside of your unit before adding the new filter to maximize its effectiveness.

A red light might indicate that it’s time to change your air filter, but don’t rely on it, as a buildup of pollutants can have health issues in your home.

Replace your air filter as often as your user manual recommends, or even before then if it seems to have accumulated too much dust.


Determine If Your Levoit Air Purifier Is Broken

A red light on your Levoit air purifier may also indicate that the device’s fan has ceased operation.

In a best-case scenario, the fan will not work because of a minor software glitch.

Unfortunately, your device may have also experienced catastrophic damage.

Here are the steps you can take if you think that your Levoit air purifier may have sustained damage.


What Can I Do If My Levoit Air Purifier Is Broken?

If your Levoit air purifier’s fan is not running, you may face a minor software issue.

Try power cycling or resetting your air purifier to fix any system glitches.

To power cycle, cut the purifier off from power for thirty seconds before turning it back on.

If your air purifier has sustained physical damage, you may have no other recourse but to contact customer support.

If the device is still covered by its warranty, Levoit may send you a new device.



If you’ve experienced an incessant red light on your Levoit air purifier, you don’t need to worry- it could be functioning exactly as you want it to.

Alternatively, it could be overdue for a filter cleaning.

In the worst-case scenario, your Levoit air purifier has sustained physical damage or suffered a software issue, and needs either a replacement or a quick reset.

No matter what the issue with your air purifier is, you have the tools to fix it!


Frequently Asked Questions


Does A Red Light Mean That I Have Poor Air Quality?

Most of the time, you will not have to worry about a red light on your air purifier, as the device will suck airborne pollutants into its filter and keep your air clean and healthy for your home’s inhabitants to breathe.

However, a red light may also indicate that your device has stopped working.

There are many things you should consider before jumping to any conclusions about your air purifier.


Should I Use The Red Light As An Indicator Of When To Clean My Air Purifier?

There are plenty of other things you should consider about your air purifier, but the assumption that you should clean it is a safe one.

If the red light on your Levoit air purifier won’t change colors or go away, it’s worth checking how dirty the HEPA air filter is.

It may be time to change your air filter or purchase an entirely new one!

We like to clean the old filter until it’s time to get a new one, but if your filter was particularly filthy, you might consider buying a new one.
