Humidifiers are useful for regulating the environment of your home. You can even get a ‘smart’ humidifier that will link up to your smart home system, making it even easier to use.

If you’re having problems with your Levoit brand humidifier, check out this helpful guide on common problems and how to troubleshoot them. 

Levoit Humidifier Making a Loud Sound

If your humidifier is making a loud noise, there are multiple potential reasons behind it. 

Here are some likely fixes:

  • The most likely cause is a clog or other debris within the system: Try cleaning or replacing the filters and clearing out any part of the humidifier, like the float system or fan, that may have collected dust or a clog.
  • Another reason for the humidifier making a sound could be a problem with the fan: Try opening the humidifier and lubricating the fan with a bit of oil. It may also help to check the screws and tighten any that may have loosened.

Now, let’s see why your humidifier isn’t turning on.

Why Is My Levoit Humidifier Not Turning On?

If your humidifier won’t turn on, it may be an issue with the water level. 

If the humidifier runs out of water, it won’t work properly. Make sure to refill the humidifier with distilled water.

You may also have to check that the humidifier is plugged into the outlet properly, and that the outlet is functioning.

Levoit Humidifier Keeps Turning Off

If the humidifier turns off unexpectedly, it may be a problem with the water level, as mentioned previously. 

For smart humidifiers, it could also be a problem with the automatic shut-off function. Check your settings and see if you’ve set an automatic shut-off without realizing.

Levoit Humidifier Keeps Saying ‘Empty’

If your humidifier keeps saying it is empty, the first thing to do is check the water levels. 

If it still has enough water, there might be a problem with the filter. Try cleaning out the filter and check that it is sitting correctly in the humidifier. 

If the problem persists, check the manual that came with your humidifier.

Levoit Humidifier Not Connecting to Wi-Fi or Smart Assistant

If your smart humidifier is not connecting to Wi-Fi, check that your Wi-Fi is working by using another device. 

On the humidifier, make sure you’ve selected the right network and password. If you have a VPN, you might have to turn it off. You can also move your humidifier closer to the router or vice versa. 

When you try one of these solutions, it may help to power down and restart the humidifier as well.

Levoit Humidifier Not Misting (But It’s On)

There are a few different causes for the LEvoit humidifier not misting but it’s still powered on.

Check the following:

  • Clogs in the filters first. This is the most likely cause of your humidifier not producing mist. 
  • The water levels. If there’s not enough water, the humidifier will not be able to produce mist. 
  • The settings. If your humidifier is on low settings, it may not be producing enough mist for your preferences, even though it is working properly.

Now, let’s see why your humidifier is blowing white dust instead of mist below.

Levoit Humidifier Blowing White Dust

If your humidifier is sending white dust into the air, or you notice it collecting on the device, that’s an indication of mineral buildup. 

This can occur if you are using tap water with your humidifier, rather than distilled water. You can simply wipe the dust away with a cloth. 

Levoit also offers absorption pads that you can add to your humidifier to combat mineral buildup.

Levoit Humidifier Auto On and Off Not Working

Similar to the issues of the humidifier turning off or not turning on outlined above, this problem has an easy solution.

Checking the water level or cleaning the filter. You also might have to check the settings you have on the humidifier or in the app to see if you’ve set up the automatic functions or not.

Inside Levoit Humidifier

To prevent this from happening, change the water regularly and clean your humidifier. To eliminate bacteria, fill the device with: 

  • Hot water
  • A cup of vinegar
  • A few tablespoons of salt

Run your humidifier for a few hours or overnight, rinse it out, and fill it with distilled water again.

Levoit Humidifier Keeps Leaking

Levoit humidifiers may leak if they aren’t placed on a stable, level surface. 

Make sure the humidifier isn’t on a tilted or uneven surface. Leaking may also indicate a clog in the system. 

For ideal humidifier function and maintenance, try to clean out the humidifier regularly.

Always Refilling Levoit Humidifier

If you find that you frequently need to refill the humidifier, check to make sure there isn’t a leak. If there is, see the information above for solving that problem.

You may also have to check your settings. If the humidifier is running constantly and on high, then the water will run out more quickly than if you run it on a lower setting or less frequently.

Now you know everything about your Levoit humidifier not working.


The best way to ensure the longevity of your Levoit humidifier is to clean it regularly and only fill it with distilled water. 

If you do this, you will likely prevent most of the problems in this guide from happening at all. If problems persist, check the user manual for your specific model, or call Levoit customer support.
