Levoit Air Purifier Making Noise? – (Easy Fix Guide)

Is your Levoit air purifier making noise? That requires your attention and some reading!

The Levoit enhances the life quality for your family and pets, but sometimes it could start making a noise, and that indicates an issue or requires maintenance.

If your Levoit air purifier is making a noise, you must check for blockages, usage overload, or a dirty filter. Alternatively, the noise could have an electrical source, which requires the maintenance of capacitors.

Below you can learn how to fix the noises of your air purifier in any situation!

Levoit Air Purifier Making Noise – Find 9 Solutions!

Solution #1: Check For Blockages

A Levoit air purifier making high-pitched noise often results from foreign objects inadvertently entering the device.

To prevent this issue, it’s crucial to place the air purifier in a location where such objects are less likely to enter.

Avoid placing it near open windows, vents, or areas with frequent small debris.

Here is how to check:

1. Power off the air purifier (and unplug it);
2. Open the device;
3. Carefully watch the device’s interior for visible foreign objects;
4. Use a soft brush or tweezers to eliminate blockage;
5. If necessary, shake the device to dislodge trapped items;

Tip: Implement regular maintenance, such as keeping the air openings clean to avoid debris accumulation and ensure excellent airflow.

Solution #2: Prevent Overload

Overloading an air purifier occurs when it is placed in a room greater than the maximum supported. This places exaggerated pressure on internal components.

Overloading the air purifier is not dangerous in terms of safety but can lead to reduced effectiveness and increased noise levels, impacting its performance.

Do the following:

1. Move the air purifier to a smaller room and test it;
2. If the noises continue, take it to an even smaller room;
3. Also, ensure that the smaller room has enough airflow.

The ideal is finding a balance between room size and airflow that allows the air purifier to get air in and out.

If you are unsure what room size your air purifier can support, it should be written on its box.

Solution #3: Check The Air Filter

Is your Levoit air purifier fan making noise? Forgetting the air filter’s replacement or forgetting the filter plastic can result in air purifiers producing annoying noise.

As time passes, the filter gets clogged, reducing its air purification effectiveness. That reduces airflow and increases the device’s strain.

What to do:

1. Remove the filter from the air purifier.
2. Use a vacuum cleaner to gently eliminate debris and dirt.
3. If additional dirt remains, employ a dry cloth.
4. Delicately wipe away any remaining debris with the cloth.
5. Reinstall the filter in the air purifier.

When dealing with the filter, ensure that its plastic bag is removed.

That is especially important when you install a new filter.

Solution #4: Verify The Fan

The fan is essential for drawing air inside the unit and flowing it across the filters to purify it.

However, dust accumulation on the blades can upset the balance, leading to high-pitched sounds and vibrations while turned on.

The fan could also have loose parts.

Let’s do the following:

1. Turn off and unplug the air purifier;
2. Use a cloth/soft brush to clean fan blades off of dust;
3. Ensure that the fan is fixed in place;
4. If it is not, try to fix it manually;
5. If necessary, disassemble the fan and check for loose components;
6. Now put those components back into place;
7. Reassemble the fan.

Furthermore, when dust or debris clogs the fan blades, it hampers airflow, causing the motor to exert more effort and generate additional noise.

This makes maintenance of the fan and its blades a regular necessity.

Solution #5: Lubricate Or Fix The Motor

The air purifier’s motor is responsible for driving the fan and all moving parts.

As time passes, motors can undergo friction due to lacking proper lubrication, leading to the emergence of worrisome noises.

While this noise isn’t hazardous, it can signify diminished motor efficiency and heightened wear.

These are the steps:

1. Disassemble the motor from the device;
2. Check for damage;
3. See if there is debris inside the air purifier;
4. Clean any debris;
5. If loose parts are present, adjust them;
6. Lubricate the motor so it can spin freely;
7. Reassemble it and see how it behaves.

Tip: When cleaning the motor, a can of compressed air is very helpful to eliminate small debris that is hard to reach.

Solution #6: Locate Loose Internal Parts

Vibrations and extended usage can result in screws, panels or other components within the device becoming loose or dislodged.

This internal component loosening causes an imbalance in the air purifier.

That leads to vibrating parts touching during operation, which ultimately produces high-pitched noises.

Do the following:

1. Turn off the air purifier (and unplug it);
2. Investigate the equipment with attention;
3. Pay special attention to screws and other smalls parts;
4. Use your toolkit to securely tighten any visibly loose parts;

Loose parts can be near the fan, motor, or any other part.

It is of utter importance that you be careful when checking your air purifier since such devices are very fragile. 

Solution #7: Check For A Whistling Capacitor

Capacitors on the electronic circuit board can emit whistling sounds. That usually happens when capacitors receive excessive voltage.

You can prevent high-pitched noise due to a whistling capacitor by ensuring proper electrical voltage supply and avoiding power surges.

What to do:

1. Disassemble the air purifier to access the circuit board;
2. Look for broken or damaged components;
3. Verify if there are blown parts or burn marks;
4. Carefully detach any blow capacitor and replace it;
5. Clean the rest of the circuitry with an anti-static brush and isopropyl alcohol;
6. Reassemble the components.

Once all the circuitry is clean and repaired, your device should no longer make noises. 

Tip: Devices that receive constant air intake will inevitably accumulate dust. Cleaning with an antistatic brush and isopropyl alcohol is a must that will help the device live longer.

Solution #8: Fix Electrical Buzzing

Electrical buzzing noises in air purifiers can originate from power electronics or internal electronic faults.

Such sounds can indicate the electrical current is unstable or an issue is happening inside the device.

Moreover, the issue could be solely on the socket being used at the moment.

So these are the troubleshooting steps:

1. Grab a multimeter;
2. Check your air purifier’s box to learn how much VAC it needs;
3. Turn off power at your power breaker;
4. Use the multimeter on the socket to test its VAC output;
5. Is the VAC on that socket too low?
6. Test the air purifier using a different wall outlet;

Check Internal Electrical Issues

If the issue is not on the wall socket, it could be located in the circuit board!

Here is how to check:

1. Open the air purifier;
2. Inspect the circuit board for visible problems (burn marks);
3. Grab a multimeter;
4. Connect it to each electrical component and test for continuity;
5. Remove electrical components that fail the multimeter test;
6. Install new components in place of the damaged ones.

Note that the tiny electrical components inside devices are very similar.

If you are not familiar with the parts inside your air purifier, you can take it to a specialized shop and get help to buy proper replacements.

Solution #9: Check The Power Cord

Have you already tested some electrical issues and none of them are inside the air purifier? Then the buzzing noise can come from somewhere else: the power cord.

Perhaps your power cord has suffered damage, and even though it delivers power, it is causing a noise. That is a bit dangerous!

Here is what you must do:

1. Touch the multimeter’s probes to the cord’s end;
2. Set to continuity;
3. If the continuity fluctuates, that is an issue!

Replace The Cord

You will have to replace the power cord to end the buzzing noises.

Here is how:

1. Purchase a power cord with the correct power specifications;
2. Carefully disassemble the air purifier (keep track of screws and components);
3. Remove the old power cord and dispose of it;
4. Install the new power cord;
5. Reassemble the air purifier;

Once you have reassembled the air purifier, plug it into the wall again. Then turn the device on and check if the noises are gone.

They should be!
