Common Issues in Levoit Air Purifiers

In the realm of air purification, Levoit has established itself as a trusted brand, offering a range of devices designed to improve indoor air quality. However, like any piece of technology, Levoit air purifiers can encounter issues that may affect their performance or usability. Let’s address the common issues in Levoit air purifiers and find solutions.

Are Levoit Air Purifiers good?

Levoit air purifiers, specifically the Core Mini model (LAP-C161-WUS), have been recognized for their reliable performance in removing airborne impurities, despite not being the top performers in the market. They are compact and easy to use, making them suitable for small spaces up to 178 square feet, such as nurseries, bedrooms, or small home offices.

The Levoit air purifier features a three-stage filter system. The outer prefilter traps larger particulates like pet dander, fur, or hair. The middle layer, a high-efficiency particulate air (HEPA) filter, captures up to 97% of particles as small as 0.3 microns. The innermost layer contains activated carbon, which absorbs odors, such as those from burned food or smoke.

One unique feature of the Levoit air purifier is a small pull-out drawer near the top of the unit that holds an absorbent disc for essential oils. This allows the purifier to not only clean the air but also fill the room with your favorite aroma.

However, it’s important to note that the Levoit air purifier took almost three times longer to remove airborne pollutants in tests compared to other models. Also, the compact model may not be suitable for use in medium-sized or large rooms.

Despite these limitations, the Levoit air purifier is an affordable option compared to other air purifiers in the market. It is quieter on all power levels than other tested air purifiers, and it comes with an Energy Star rating, indicating its energy efficiency.

How to Reset Levoit Air Purifier?

How to Reset Levoit Air Purifier

Resetting a Levoit air purifier is a straightforward process that is essential to perform after installing a new 3-in-1 HEPA filter. The reset button is typically located at the top of the unit for most models, including the Core series (300, 300s, 200s, 600s, Mini, P350), Vista 200, and LV series (LV-H126, LV-H128, LV-H132, LV-H133, LV-H134, LV-H135).

To reset your Levoit air purifier, follow these steps:

  1. Power on your air purifier.
  2. Locate the reset button on your unit.
  3. Press and hold the reset button for three seconds.

Upon successful reset, the filter reset button will stop illuminating red, and the air purifier will produce a beep sound, indicating that the reset has been successful.

However, it’s important to note that not all Levoit air purifiers have their filter reset button at the top of the unit. For instance, the Levoit LV-Pur131 and Levoit LV-Pur131S have their filter reset button located at the side, below the dust sensor cover. The button is right behind the vent, so you’ll need to use a small object (like a pen, pencil, or toothpick) that will fit through it to press the reset button.

Remember, regular filter changes and resets are crucial for maintaining the efficiency and longevity of your Levoit air purifier.

What do the light indicators on my Levoit Air Purifier mean?

Light ColorIndication
RedBad Air Quality
YellowModerate Air Quality
GreenGood Air Quality
BlueVery Good Air Quality

The lights on a Levoit air purifier serve as indicators of air quality and filter status. If your Levoit air purifier is blinking or shining red, it could mean one of two things.

A red ring on your Levoit air purifier indicates that it has detected a high level of airborne pollutants indoors. If the Auto mode is on, the purifier should automatically switch the fan to work at high speed until the air quality improves, at this point, the ring color will change from red to green or blue, indicating good or very good air quality, respectively.

Alternatively, you can manually turn on the highest speed for a few hours until the red circle changes to blue. Here are the Levoit color codes for air quality:

If your Levoit air purifier is shining red and it’s not related to the air quality index, it indicates that you need to replace the HEPA air filter. After replacing the filter, if the red light doesn’t turn off, you need to press the red filter reset button and hold it for three seconds to turn the light off.

However, if the red light continues to flash despite following these steps, it’s recommended to contact Levoit customer service for further assistance. Understanding these light indicators can help you maintain the optimal performance of your Levoit air purifier and ensure good air quality in your space.

Levoit Air Purifier Not Turning On?

Levoit Air Purifier Not Turning On

If your Levoit air purifier is not turning on, there could be several reasons for this issue. Ensure that the power is turned on at the outlet. If the power is on and the purifier is still not working, the electrical cord might be faulty. Over time, the power cord can wear out, so it’s a good idea to test this and replace it if necessary. Another possibility is that the outlet itself is damaged. Try using another outlet to plug in your purifier to see if this resolves the issue.

Incorrect placement of the back cover could also prevent the air purifier from turning on. Double-check that you’ve placed the cover correctly. Additionally, if the power rating is incorrect, your purifier won’t turn on. Check the outlet to make sure that the power rating is right. The power ratings for various Levoit air purifier models are provided on the manufacturer’s website.

If you’ve tried all these solutions and your Levoit air purifier is still not turning on, it might be best to contact Levoit’s customer support. They are available Monday through Friday, from 9 am to 5 pm PST, and can be reached by phone at 1-888-726-8520 or by email via [email protected]. They also offer an instant chat function on their website, which allows you to describe the problem and submit attachments such as photos.

Is it safe to keep the Levoit Air Purifier turned on continuously?

Yes, you can leave your Levoit air purifier on all the time. In fact, keeping your air purifier running constantly can help maintain a consistently high level of air quality in your home. When the air purifier is turned off, the air in your home will circulate naturally, introducing new contaminants into your room. Your unit will then have to work at a high fan speed to restore the air quality to a healthy level.

By keeping your air purifier running constantly, you ensure that your air quality stays at a consistently high level. This means your unit won’t have to overwork, which can cause issues with the purifier. Moreover, Levoit air purifiers are designed to be energy efficient, so you don’t have to worry about excessive energy consumption.

However, it’s important to remember that regular maintenance is crucial for the longevity and efficiency of your Levoit air purifier. This includes cleaning the pre-filter monthly, replacing the HEPA filter when it’s full, and cleaning the interior and exterior of the unit. Regular maintenance will ensure your air purifier continues to operate at its maximum efficiency.

Levoit Air Purifier Touch Screen not Working?

Levoit Air Purifier Touch Screen not Working

If your Levoit air purifier’s touch screen is not working or the display isn’t showing anything, you can try several troubleshooting methods.

  1. Consider rebooting the device: Often, glitches can cause the touch screen to malfunction, and a simple reboot can usually resolve these. To do this, turn off your device for a few seconds and then turn it back on. This process is known as power cycling and can often rectify minor technical issues.
  2. Ensure that the appliance is clean: Although it’s a less common cause, a dirty air purifier can sometimes act up. Make sure to clean the filters and the display of the purifier. If the problem persists even after cleaning, you might be dealing with a more technical issue.
  3. Try resetting the device: This will restore your device’s state to its default settings. However, be aware that the process to reset the appliance may vary depending on the model you have. It’s advisable to follow the instructions mentioned in the user manual guide. Remember that resetting the device will cause you to lose all your stored settings.

Tip: If your device is still under warranty, you can reclaim it. It’s possible that you might have received a faulty unit from the start. If your device isn’t under warranty, you may need to consider getting a new unit. Always ensure to get a brand-new replacement that is under warranty to avoid facing similar issues in the future.

Remember, while these issues are often the result of a physical fault, it’s essential to rule out other possible causes before deciding to spend money on a new unit.

Reduced Airflow?

Reduced Airflow

Reduced airflow in your Levoit air purifier can be attributed to several factors.

  1. The fan speed might be set to low: You can adjust the fan speed by tapping the fan speed button to increase it from 1 to 2 or 3. Using the auto mode function can also help increase the fan speed as it detects and removes pollutants.
  2. Packaging of the filter might not have been removed: The packaging can significantly reduce the airflow, so it’s crucial to ensure that all packaging has been removed before operating your unit.
  3. Placement of your purifier can affect the airflow: The airflow can be reduced if the air intake and outlet are too close to other objects. To resolve this, you should change the location of your purifier to allow more space around it.
  4. The size of the area you’re trying to purify can affect the airflow: If the room is larger than the recommended size for your purifier, it might seem like the unit isn’t cleaning the air properly.

It’s essential to use the purifier in the recommended room size, which can be found in the manual.

Levoit Air Purifier Making Noise?

Levoit Air Purifiers Making Noise

If your Levoit air purifier is making noise, there could be several reasons behind it.

One common cause is foreign objects or debris falling into the device. Small items like scraps of paper, tiny bugs, or miniature toys can cause blockages and result in high-pitched noises. To resolve this, turn off and unplug the air purifier, inspect the inside for any visible objects, and gently remove them. Regular maintenance, including cleaning the air intake, is also essential to prevent debris buildup and ensure optimal airflow.

Another reason could be overloading, which occurs when the air purifier is used in a space larger than its intended capacity. This puts excessive strain on the motor and other internal components, causing them to work harder and generate more noise. To troubleshoot this, refer to the manufacturer’s guide or owner’s manual for the recommended room size or coverage area for your specific air purifier model.

Neglecting to replace the air filter on schedule or failing to remove the filter bag can also lead to high-pitched noise problems. Over time, the filter becomes clogged and less effective at purifying the air, resulting in reduced airflow and increased resistance within the air purifier. As a result, the motor and other internal components have to work harder, leading to squealing noises. To address this, consult your owner’s manual or manufacturer’s instructions for the recommended frequency of air filter changes.

Dust and debris can gather on the fan blades, leading to an imbalance that disrupts smooth rotation and causes vibrations and high-pitched noise during operation. Regularly cleaning the fan blades can help restore proper airflow and reduce noise levels.

The motor, which powers the fan and other moving components of the air purifier, can experience wear and tear or may not receive sufficient lubrication, resulting in increased friction and high-pitched noise during operation. Referring to the owner’s manual or the manufacturer’s lubrication guide for instructions and applying the appropriate lubricant to the motor can help reduce friction and minimize noise.

Vibrations and continuous usage can cause screws, panels, or other fasteners inside the air purifier to loosen or detach. This creates an imbalance within the air purifier, leading to parts vibrating and colliding with one another while in operation, thereby generating high-pitched noises. To address this, turn off and unplug the air purifier, carefully examine the equipment, and tighten any visibly loose components.

Is your Levoit air purifier emitting unpleasant odors?

Is your Levoit air purifier emitting unpleasant odors

If your Levoit air purifier is emitting a bad smell, it could be due to a variety of reasons. One common cause is the presence of plastic inside the unit, often because the plastic bag covering the filters was not removed. This can be quickly resolved by removing the plastic bags from the filters.

Another possible cause is a burning smell, which could indicate a mechanical issue with the unit’s electrical components. This could be due to the motor being overworked or a fault in the circuitry. If your air purifier is in a room without proper ventilation, it may overheat and produce a burning smell. If the smell persists even after ensuring proper ventilation and cleaning the fan, it is advisable to send the device back to the manufacturer for repairs or replacement.

A dirty smell is usually a sign that the filters are dirty and need to be replaced. If the smell persists even after replacing the filters, it could be due to other sources of odor in the room.

A wet dog smell could indicate the presence of dampness or moisture inside the machine, which could be reacting with mold or other bacteria. This issue can usually be resolved by changing the filters and inspecting your surroundings for any signs of mold or mildew.

If your air purifier smells like a swimming pool, it could emit ozone gas, which can cause severe damage to your lungs and respiratory system. In this case, you should immediately shut off the machine, ventilate the environment, and contact a professional for repair.

A sweet smell could be due to the need to replace your activated carbon filter or a sign of a new machine. If the device is not new and doesn’t have an activated carbon filter, it is recommended to have a professional inspect the machine.

Remember, any unusual smell from your air purifier is a sign that something is wrong and should not be ignored. Always take appropriate action to ensure the safety and effectiveness of your air purifier.


Levoit air purifiers are made with top-notch quality standards and advanced technology. However, sometimes they may face issues that can affect their performance. But with the proper knowledge and guidance, most of these problems can be fixed quickly, ensuring your device continues to provide clean, fresh air for your home or office.

It is important to remember that regular maintenance and timely troubleshooting can help extend the lifespan of your device and ensure it operates at its best. If you still have issues, don’t hesitate to contact Levoit’s customer service for further assistance. You can breathe easy knowing that with a bit of care and attention, your Levoit air purifier will continue to improve the quality of your indoor air for years to come.
