Levoit Problem #1: Purifier Won’t Turn On

It can be really frustrating when your air purifier won’t turn on at all, which is why we’ve started with a few helpful tips for troubleshooting Levoit Air Purifiers.

❓ Is the unit plugged in and powered on?

Make sure the unit is plugged in and turned on. If not, plug it in and turn it on.

❓ Is there a problem with the electrical cord?

Unlikely, but the power cord could wear out over time. Examine and test the cord. If there is an issue with the cord, contact Levoit customer care.

❓ Is it the outlet you are using? Is there power?

Try another outlet to plug in your purifier to test and troubleshoot further.

❓ Is the back cover attached incorrectly?

Double check that you’ve re-attached the cover well to see if the air purifier powers on and works properly.

❓ Is the power rating correct? Incorrect outlet power?

If the outlet power rating isn’t correct, your purifier won’t turn on. Check/Test the outlet to make sure that the power rating is right.

Levoit Problem #2: How to reset the Levoit air purifier red light?

A common issue with Levoit air purifiers is the filter indicator system. The purifier displays a red light to signal when a filter replacement is necessary. However, customers have noticed that this warning light remains on or flashes even after replacing the filter. The Levoit red light problem ranks among the most common problems for Levoit purifier owners, so let’s fix it!

❓ Is the filter installed correctly?

Should your air purification device emit unusual sounds, it is probable that the filtration component has been improperly positioned. Disconnect the electrical power supply to the purification unit and extract the filter from the apparatus to verify its proper installation. Subsequently, reinsert the filtration element to determine whether the issue has been successfully addressed.

❓ Do you need to reset the filter indicator?

Turn the purifier off, then press and hold the filter indicator reset button for 3 to 5 seconds.

For the Levoit PUR131 and PUR131S, you’ll need to use a small screwdriver, paperclip or whatever to press and hold the internal button for 5 seconds or until you hear a beep. 

Following the beep, the red light will turn off, and no other lights will display.

❓ Are the filters blocked by debris or clogged?

Remove anything blocker the filter or replace clogged filters with new filters, if necessary.

Step-by-Step Guide:

1. Open the filter cover and remove the clogged filter.
2. Pro Tip: vacuum the inside of the unit and remove built-up dust particles, hair, and similar dirt and debris.
3. Unpack and unwrap the new filter, insert it into the unit and close the lid.
4. Finally, reset the filter indicator as described.

❓ Is there built-up debris in the filter compartment?

Remove the filter and clean debris from the purifier housing using a non-abrasive brush or vacuum.

❓ Are there programming issues with the Levoit air purifier?

Still having problems? Your purifier might have problems with programming.

Follow these steps:

1. Unplug the unit for around 30 seconds.
2. Plug in power, and turn on your unit.
3. Press and hold the check filter status button for three seconds and and wait for a response from the purifier.

Levoit Problem #3: Reduced airflow

Your air purifier works best when air can flow freely through it, but sometimes that flow gets messed up for different reasons. It’s super important to keep that airflow going strong if you want your purifier to do its job properly.

❓ Is the fan setting too Low?

Adjust the fan speed by pressing the fan speed button repeatedly and move up from 1 to 2 or 3.

❓ Has the filter packaging been removed?

If you don’t remove all packaging, this can significantly reduce the airflow. Make sure you’ve removed it before operating your unit.

❓ Is there a lack of clearance?

Reduced airflow can occur if the air intake and outlet are placed too close to objects. Simply change your purifier’s location to leave more space around it.

❓ Is the area you’re purifying larger than the recommended size?

You might feel that the unit isn’t cleaning the air properly when in fact you’re using it in a room that’s too large. Be sure to use the purifier in the recommended room size. This info can be found in the manual.

Levoit Problem #4: My Levoit air purifier is beeping and/or making weird noises

If you tend to use your purifier while sleeping or resting, you certainly don’t want it to be making strange noises.

❓ Does the filter need changing?

Your Levoit instructions manual can help to ensure you get the correct filter replacement. See our instructions above for detailed guidance on how to change your filters.

❓ Is there a foreign object inside?

If you find something that shouldn’t be there, turn off the unit and unplug it from the outlet.

Be sure that you don’t open the air purifier. Instead, contact the support team by phone on 1-888-726-8520 or by email via support@levoit.com, they can help you solve the issue.

❓ Is the back cover placed incorrectly?

Make sure that this is fitted properly.

❓ Is there too much dust inside the purifier?

If this is the case, unplug your unit, turn it off and get rid of the excess dust using a vacuum cleaner.

❓ Does your Levoit air purifier need to be reset?

If you hear a beeping noise while your air purifier is running, it likely needs to be reset.

Follow these steps:

1. Ensure the device is plugged in but switched off.
2. Press and hold the filter reset button for three seconds.
3. The reset is complete when the light turns off after releasing the button.

Should the audible alert persist, execute this procedure once more. If the acoustic signal remains audible after the second attempt, please communicate with our customer support department, as this may indicate a technical malfunction. Reference the conclusion of this document for Levoit Customer Care contact information.

Levoit Problem #5: My Levoit air purifier produces an unpleasant smell during usage

Should you perceive an undesirable scent within the vicinity of your air purification device, it may indicate a malfunction in the system. However, this conclusion is not necessarily accurate in all circumstances. Occasionally, intense odors and substantial smoke concentration can compromise the efficiency of the filtration mechanism. In such instances, the excessively contaminated filter may emit an unpleasant odor.

❓ Does the filter need cleaning?

As Levoit air purifier filters aren’t waterproof, you should never wash and reuse them. Instead, try gently blowing compressed air on the unit.

If the filter has been in the system for over six-to-eight months, it’ll be time to replace it.

❓ Is the room adequately ventilated?

To eliminate any strong odors or smoke, be sure to air out the room before running the purifier.

❓ Is the filter causing the smell?

Remember that new filters have just left the factory. They haven’t been ventilated, and are immediately packed, so the unpleasant smell lingers in them.

To combat this problem, leave the unit running for at least 24 hours in an area where you’re not around. This will help to ventilate the filter and make it fresh.

Levoit Problem #6: Air purification isn’t working

When you’ve bought an air purifier, it can be pretty annoying if the unit isn’t cleaning your air effectively. You might be eager to get your system up and running, but it’s vital to read the user manual thoroughly to ensure correct setup. This is often the most common reason why the unit isn’t purifying the air.

❓ Has dust built up on the filters?

Dust can build up and can cause problems, as we’ve already seen. Remember, you should never wash and resume a HEPA filter.

Vacuuming them can cause damage and stop them working. If you really want to try cleaning your filter, be very gentle. But we really do recommend replacing them.

❓ Is the room coverage too large?

If you use the purifier in a room larger than 300 square feet, it can lead to poor air quality. Be sure to only use it in the recommended room size.

Air Purifier Model	Ideal Room Size in Square Feet	Ideal Room Size in Square Meters
Core 200S	≤ 183 ft²	≤ 17 m²
Core 300	219 ft²	20 m²

❓ Is the interior air quality poor?

Air out the room before running your unit. Once the room is well ventilated, close all doors and windows and then run your purifier.

❓ Is the air inlet or outlet blocked?

Allow enough clearance around the purifier and remove objects that may block the inlet and outlet.

❓ Is the purifier in the corner of the room?

The instruction manual advises setting up the purifier around the middle of the room for optimum performance. Simply reposition the device and the purification should start working.

Levoit Problem #7: My Levoit air purifier won’t connec or sync to the app

Successful app connectivity is essential for the smooth running of your purifier, but unfortunately this can sometimes be a problem.

❓ Are there network problems?

Check that your internet modem is supported and make sure it works at 2.4GHZ. If it works on 5GHz, switch it to 2.4GHz and try connecting again.

❓ Have you entered the wrong Wi-Fi password?

Be sure to check this and also that you haven’t left any spaces at the beginning or end of the password.

❓ Is your VPN turned on during setup?

Ensure that you turn off your VPN throughout this process.

❓ Is the unit too far from the modem?

Make sure that your modem is close enough to the unit to work correctly.

❓ Do you need to use a hotspot?

If none of the above work, try using a hotspot from another smart device as a modem. This should enable you to connect the VeSync app with the purifier.

Levoit Problem #8: My Levoit purifier isn’t connecting to wi-fi

As well as the app, sometimes there can be connectivity issues with the Wi-Fi. It may be that your purifier simply needs rebooting. You can try this, as well as following these tips.

❓ Does the system need restarting?

Unplug it from the outlet for 30 seconds, then plug the unit back in. You should hopefully be able to connect again.

❓ Does the VeSync app need an update?

Open the VeSync app and check if there’s a firmware update available. If so, follow the instructions to update the software. Deleting the VeSync app and reinstalling again can also do the trick.

❓ Are small appliances creating interference?

Be sure to keep your air purifier a good five feet away from small appliances to avoid interference.

❓ Is your phone too far away from the purifier?

Ensure that your phone is close to the system. An iPhone has to be within about 33 feet of the air purifier to work.

Levoit Problem #9: My Levoit air purifier display isn’t working

While it’s fairly uncommon, issues with the display can occur. The worst outcome is that there’s a malfunction in the system, and a replacement is the only solution.

❓ Are there power issues with the unit?

Firstly, connect a different appliance to the outlet and check the response. If the outlet is faulty, all you need to do is to find a different spot for your purifier.

❓ Is the cord damaged?

If a different appliance works fine with the outlet, then you need to check the power cord for possible damage. When this happens, it’s best to contact Levoit to secure a replacement.

If you want the issue fixed quickly, taking your unit to a repair center is another option.

❓ Are there programming issues?

Try power-cycling (turn it off and on again) the purifier and then judge the response from the display.

If there aren’t any hardware issues with the control board, shut down the purifier for a few minutes and turn it back on.

❓ Is there water damage?

Levoit units don’t operate well when there’s water damage. In this instance, you’ll have to claim the warranty.

1. Make sure your product is within the specified warranty period.
2. Make sure you have a copy of the invoice and order ID or proof-of-purchase.
3. Make sure you have your product. DO NOT dispose of your product before contacting us.
4. Contact Levoit Customer Support team via support@levoit.com.
5. Once the Customer Support team has approved your request, return the product with a copy of the invoice and order ID. 

❓ Does your air purifier need to be reset?

Reset the unit – you could even go back to factory settings – and then try using your display one more time.

1. While the unit is on standby, press and hold the filter reset button for 3 seconds. The filter reset button will light up.
2. Press and hold the filter reset button again for 3 seconds, the filter reset button will now turn off. 

The reset is now complete.

Levoit Problem #10: All the lights on my purifier display are on

Should you observe all indicator lights illuminated at once on your purifier, this signals that the unit is not functioning properly. This typically suggests an internal system error that can be remedied relatively easily.

❓ Does the unit need resetting?

Press and hold the power button down for at least 3 seconds. Release the button then press and hold again for a few more seconds.

If this doesn’t work, hold down the power switch button for five seconds each time.

❓ Does the purifier needs to be unplugged?

Unplug the purifier for at least 30 minutes and plugging it back in.

Levoit Problem #11: The air purifier fan isn’t working

The fan mechanism within the air cleaner plays a crucial role in its operation. When this component malfunctions, it can compromise the cleaning effectiveness. Frequently, issues with the fan can be traced back to problems with the filtration element.

❓ Did you remove the plastic packaging from the filter?

 Check if the plastic the filter came in is still on the filter, if so, remove it. Also, check that you’ve installed the filter correctly.

❓ Do you need to press the fan icon?

Once more, while this might seem obvious, ensure you’ve activated the fan symbol on the screen. When you do this, the fan’s velocity will be enhanced.

❓ Is the purifier in sleep mode?

On most Levoit models, if the purifier fan is still running but it’s very very quiet or almost unnoticeable, then it’s sleeping/in sleep mode. To wake it, press the sleep mode button icon to turn off sleep mode.

❓ Is there anything blocking or covering the sides of the purifier?

Anything that could protentialy block or cover the sides of the purifier should be moved, this is an easy one to understand and prevent.

Levoit Problem #12: Air quality indicator is showing incorrect status

A common issue is that the air quality indicator displays the incorrect status. Most of the time, the indicator is malfunctioning because there’s a problem with the dust sensor.

❓ Do I need to clean the dust sensor?

A red light is supposed to mean that the air quality is bad. But if you’re overworking the purifier, but if you’re running the purifier at 100% pretty often, then it’s time to clean the dust sensor.

Quick Step-by-Step Guide:

1. Firstly, open the sensor cover to access the air quality sensor.
2. Using a damp cotton swab, clean the sensor lens.
3. Dry the sensor lens thoroughly with a dry cotton swab.
4. Close the sensor cover.
