The red light on your Levoit air purifier means it needs your attention. It might seem scary at first, but knowing what it means helps keep your air clean. A survey by the Indoor Air Quality Association found 78% of users saw better health when they took care of their air purifiers.
TL;DR
Levoit air purifiers are generally reliable, but users may see a red warning light. This common issue usually has a simple solution.
The red light on a Levoit air purifier typically means the filter needs replacement. Other possible causes include a damaged filter, incorrect filter installation, or an internal error after installing a new filter.
To fix the red light, follow these steps:
- Unplug the purifier: This is crucial for your safety, preventing any risk of electric shock while working with the appliance. Then, open the filter compartment.
- Remove and check the filter: Carefully take out the old filter and inspect it for excessive dust buildup, tears, or other damage.
- Replace if needed: If the filter appears overly dirty or damaged, replace it with a new Levoit filter. Remember to remove any plastic wrapping from the new filter before installation.
- Reset the filter timer: This step is essential to tell the purifier that a new filter has been installed. For most models, hold the filter change button for 3-5 seconds. For PUR131 models, you might need to use a screwdriver to press the reset button.
Levoit filters should be replaced every 6-8 months. Premium filters may last up to 15 months. Replacement frequency depends on air quality and usage. For example, smoky or dusty environments require more frequent changes. Regular maintenance, such as vacuuming the pre-filter, can extend filter life. A clogged filter reduces performance by limiting airflow and decreasing filtration effectiveness.
Troubleshooting
If replacing the filter and resetting the timer doesn’t solve the problem, consider these additional steps:
- Check filter installation: Ensure the filter is correctly seated in the compartment. An improperly installed filter can trigger the red light.
- Inspect for obstructions: Make sure nothing is blocking the air intake or outlet of the purifier.
- Try a power cycle: Unplug the purifier for a few minutes, then plug it back in. This can sometimes reset internal sensors.
- Review the user manual: Consult your Levoit model’s user manual for specific troubleshooting steps or error codes related to the red light.
If the red light persists after trying these steps, there may be an internal fault. Contact Levoit’s customer service for further assistance or to inquire about warranty options.

What does the red light mean in a Levoit unit?
If the red light appears on your Levoit air purifier, you may as well throw it in the trash right now.

Just kidding!
This warning light is not the end of the world. In fact, itโs one of the most common issues Levoit users face, and there is usually a super simple solution.
The most common reason why there might be a red light on your Levoit right now is because the filter has reached the end of its lifespan. As Levoit uses mechanical filters, they will become saturated with particulate matter and, over time, lose efficiency.
However, you may also experience the red light if your filter is broken or incorrectly installed. And Iโve also encountered the red light after installing a new filter due to an internal glitch.

Four steps to fix the Levoit air purifier red light warning
Getting rid of the Levoit red light should be an easy fix. Follow these simple steps to get rid of it:
Step 1: Open the filter compartment
First things first, disconnect your device from the power source.
Once it is safe to proceed, open the filter compartment. The filter compartment will vary between models but is usually located inside the purifier chamber, which you access by twisting the casing or top/bottom of the device. Alternatively, it may be a simple hatch door located at the rear.
Step 2: Remove the filter from the unit
Levoit filters usually need to be replaced every 6-8 months. If you canโt quite remember the last time you changed yours, take a peek inside to check its condition.

Filters will display a deteriorated condition over time as they capture polluting particles such as hair, dust and smoke. If your filter resembles the one above, itโs time to clean the pre-filter.
Tip: Before going the filter replacement route (step 3), itโs worth testing if the red light is flashing due to the filter not being correctly installed.
If you remove the filter from your Levoit and you can see itโs clean (or if youโve just installed a new filter but canโt seem to get rid of the red light), try reinstalling the filter and skipping to step 4 in order to reset the red light to see if that fixes the issue.
Levoit Core units have a cylindrical filter that is pretty straightforward to install. Some of them have a top with a legend, so you know the filter goes on top.
The filter on the LV-H132 is a bit different from most Levoit filters, so check out this video to learn how to place it correctly.
The filter in Levoit Vital units is completely different from the two above. Here is a video showing how to remove and replace it:
Lastly, if you own a Levoit EverestAir, then here is a video you can watch to see how to open the filter cover to properly remove and replace the filter:
Step 3: Change your filter
Whether your filter is clogged with pollutants or has broken entirely, you will need to replace it to continue cleaning the air effectively.
Start by carefully removing the old filter and disposing of it appropriately. Next, remove the outer plastic wrapping on your new filter and slot it into place before reassembling the purifier.
Step 4: Hit reset
Some users may find that the red light is still illuminated after youโve changed the filter. If this is the case, youโll need to manually reset the filter change timer.

To do this, hold down the filter change button for 3-5 seconds. After that, the light should disappear until it is time to replace the filter again.
Do you have a Levoit PUR131?
For those using the Levoit PUR131, you will need to locate the reset button on the back of the unit and insert a small screwdriver for 5 seconds or until the unit beeps.
Common questions about the red light in Levoit units
Can I use my Levoit even when the red light is on?
If the red light has appeared on your Levoit as a routine filter change warning, thereโs nothing stopping you from continuing to use your air purifier while you wait for the replacement to arrive. However, you can expect to see decreased efficiency during this time.
If you are confident the filter doesnโt need to be replaced, reset the warning light and make a mental note to manually schedule future filter changes
How often should I change the filter in my Levoit air purifier?
Levoit filters usually last somewhere between six and eight months. If you’ve got one of their premium filters, like the one for the Everest Air, it could even go for up to 15 months.
But, here’s the thing: how long your filter actually lasts can change. It really depends on how much you use your air purifier and what kind of stuff it’s cleaning out of the air. For instance, if you’re dealing with a lot of cigarette smoke or construction dust, your filter’s gonna get used up a lot faster than if it’s just dealing with regular stuff like pollen.
Also, you can help your filter last a little longer if you’re careful about vacuuming and cleaning the pre-filter every now and then. Just remember, never use water or any cleaning liquids on the filter itself!
Does a clogged filter affect the performance of my Levoit air purifier?
When filters reach their saturation point, their performance decreases significantly.
The filtration process involves air passing through the filter, where pollutants are captured. A filter that is full restricts airflow, which reduces power, and also allows more pollutants to bypass the filter.
This is the reason filters have a recommended lifespan, and consistent filter replacement is crucial.
