Levoit Humidifier Making Noise? – (Quick Fix Guide)

Levoit humidifier making noise can be incredibly irritating.

Because humidifiers often have a couple of moving parts, it’s hard to understand which complement is causing the issue.

Don’t worry, as in this guide, we will guide you through fixing it!

To fix your Levoit humidifier making noises, clean its internal area thoroughly. Next, ensure its filter is in working condition and check for its fan.

Lets now see the common causes for this noise:

Why Does the Levoit Humidifier Make Noise?

If your Levoit humidifier is making either a high-pitched noise or a rattling sound, it’s likely due to a hardware component that is malfunctioning.

If you are hearing a coil-whine-type noise, it could also be due to a power issue caused by a bad capacitor. 

Here is a quick list of the most common causes for Levoit humidifier making noise:

1. Mineral Buildup on Components
2. Low Water Level
3. Faulty or Dirty Fan
4. Vibration From an Uneven Placement.
5. Clogged Filter
6. Electrical Damage.

Now that we have shown you the biggest culprits that cause humidifier noises let’s see how to fix them.

How to Stop Levoit humidifier making noise?

Tip: Follow the steps in our guide in the given order for the best outcome.

1. Clean the Humidifier

One of the first steps to stop the Levoit humidifier from making loud noise is to ensure your humidifier is properly clean and serviced.

If there is a mineral buildup as your humidifier processes water over time, it can cause issues for its internal components. 

Here are the general steps to clean a Levoit humidifier:

1. Turn off and unplug the Levoit humidifier.
2. Remove the water tank and drain all the water. 
3. Clean the base with a soft cloth or brush. A mixture of vinegar and water can help remove scale or mineral buildup.
4. You can also use a moderate detergent, such as soap, to remove the vinegar smell. 
5. Note: never mix bleach-based detergents with vinegar, which can cause a toxic reaction.
6. Rinse the tank with clean water several times until the detergent is gone.
7. Let the parts dry completely before reassembling and turning the unit back on.

Note: Check your Levoit humidifier water level and ensure it's not overfilled.

2. Check for Loose parts

In some cases, during transportation or regular use, some internal parts inside your Levoit humidifier can loosen up.

This is the most common cause of a rattling sound from your humidifier.

The fix depends on identifying which component is loose and tightening its tolerances to stop the noise.

Here is an excellent way to check for loose parts inside your Levoit humidifier:

1. While the Levoit unit is powered off, gently shake or tap it.
2. If you hear rattling, try to identify the loose component.
3. Open your humidifier side or top panel to access the loose part.
4. Tighten or properly place any components that appear to be out of place.
5. Reassemble any components and put the cover back on.

After these steps, you should no longer hear a rattling. If the noise persists, it’s likely due to a part-specific issue. Keep on reading to see how to fix those.

Note: For loose components after shipping, check with your courier for a replacement.

3. Lubricate the Fan Bushing

Most Levoit humidifiers, depending on their model, use some form of an internal fan to distribute and disperse the mist.

This fan can become worn down, creating an unpleasant and loud noise whenever you turn on your device.

To prevent this high-pitched noise, you must ensure the fan runs smoothly.

1. Disconnect and turn off the humidifier.
2. Remove the outer casing or cover to access the fan.
3. Depending on the model, you might need to remove screws, clips, or slide panels.
4. Clean the fan and bushing area.
5. Use a non-conductive lubricant or fan motor lubricant.
6. Apply 1-2 drops onto the bushing.
7. Reassemble the humidifier and test the humidifier for noise issues.

If this solves your noise issue, your fan might need regular maintenance in the future. The frequency of servicing depends on the usage of your humidifier.

If your humidifier lacks a fan, ignore this step and proceed with checking the filter.

Note: Not all Levoit humidifiers are designed to have their fan bushings lubricated. 

4. Examine the Filter

If there is an issue with your Levoit humidifier filter, it can cause an unpleasant sound, as your device will struggle to take in water and turn it into mist.

Depending on the condition of your filter, sometimes cleaning it won’t fix it, and it could need a replacement. 

Here is how to examine and fix a filter issue for your Levoit device:

1. Turn off and unplug your Levoit humidifier from the power outlet.
2. Access the side or back panel, gently open the unit, and inspect the filter.
3. If the filter is dirty, clean it by vacuuming any dirt and then gently wiping it down with a soft cloth.
4. When the filter is dry and clean, ensure it is correctly placed during reassembly.

Note: Only use official and certified Levoit filters in your humidifier.

5. Replace the Fan

Sometimes, fixing the fan or lubricating its bushing won’t be enough to eliminate the noise from your Levoit humidifier.

If you have identified that your humidifier’s internal fan is the issue, replacing it with a new one is best.

The steps below are generalized and can vary depending on your exact Levoid model.

Here is how to replace your Levoit humidifier fan:

1. Disconnect and turn off the Levoit humidifier.
2. Remove the water tank and external obstructions.
3. Open the humidifier body/cover as you did in the previous steps in our guide.
4. Identify and disconnect the fan wiring – fans usually have one red and one black wire. 
5. Remove the old fan and install the replacement fan.
6. You can connect its wires to the fan power output in multiple ways depending on your available tools.
7. After the wires of the new fan are attached, snap the fan back in place and reassemble the humidifier.

Always double-check that the replacement part you order is the same type as the one used in your Levoid humidifier.

If in doubt, contact Levoit customer support to find out how to order a replacement part.

Note: Soldering the wires to the proper power output is best; alternatively, you can use clamps.

6. Clean the Ultrasonic Disk

The ultrasonic disk is a device that uses a high frequency to generate a mist. When it’s vibrating at a very high pace, the water coming into contact with it vaporizes instantly.

If there is mineral buildup on the ultrasonic disk, it can produce a very unpleasant high-pitched noise. To prevent this, you need to ensure it is clean.

Here are the steps to clean your Levout humidifier ultrasonic disk:

1. Power down your humidifier, remove the water tank and remove its cover.
2. Access the ultrasonic disk by looking for a small metal disk connected with two wires.
3. Wipe the disk gently with a soft cloth; don’t use hard detergents as they might corrode its components. 
4. If there’s mineral buildup, use a diluted vinegar solution and carefully wipe it down.
5. Rinse with clean water (if you use vinegar).
6. After cleaning it, ensure it’s completely dry before turning on your humidifier.
7. Reassemble the humidifier, refill it, and then test if the noise is gone.

Note: If you can't easily access the ultrasonic disk, check which parts must be removed first.

Quick Recap

To fix the Levoit humidifier making noise, start by thoroughly cleaning and servicing the internal compartment.

Afterward, clean the filter and replace it if needed. Next, check if your fan is the culprit of the high noise.

Lastly, clean the ultrasonic disk and reassemble your Levoit humidifier.
