Troubleshooting Low Mist Output from Diffuser

If you’re a fan of essential oils and aromatherapy, chances are you’ve used a diffuser at least once in your life.

A diffuser is a device that disperses essential oils into the air, creating a pleasant and therapeutic atmosphere in your home, office, or car.

However, like any electronic gadget, a diffuser can encounter some problems, such as low mist output.

In this post, we’ll discuss the common causes of low mist output and provide some troubleshooting tips to help you fix the issue and enjoy your diffuser to the fullest.

Reasons for Low Mist Output

Before we dive into the solutions, let’s explore the reasons why your diffuser may not be producing enough mist. Here are some possible causes:

  1. Water level: If your diffuser’s water level is too low, it may not be able to generate enough mist. Make sure to fill the water tank to the recommended level and avoid overfilling it.
  2. Type of water: Hard water, tap water, or mineral-rich water can clog or damage the diffuser’s ultrasonic plate, which is responsible for creating mist. Consider using distilled water or filtered water to prevent this.
  3. Essential oil ratio: Using too much or too little essential oil can affect the mist output. Follow the instructions on the manual or experiment with different ratios to find the right balance.
  4. Clogged or dirty parts: Over time, the diffuser’s ultrasonic plate, nozzle, or other parts can accumulate mineral deposits, dust, or residue, which can obstruct the flow of mist. Regular cleaning and maintenance can help prevent this.
  5. Power source: If your diffuser is battery-operated, make sure the batteries are fresh and fully charged. If it’s plugged into an outlet, check if the outlet is working properly.

Solutions to Low Mist Output

Now that you know the possible causes, let’s see how to troubleshoot each one:

  1. Water level: Simply add more water to the tank until it reaches the recommended level. Avoid adding too much water, as it may spill or cause other problems.
  2. Type of water: Use distilled water or filtered water to avoid mineral buildup. If you’ve already used tap water or hard water, try cleaning the diffuser with a solution of water and vinegar or citric acid to dissolve the deposits.
  3. Essential oil ratio: Experiment with different essential oil ratios to find the right balance. Start with a small amount and gradually increase it until you achieve the desired scent and mist output.
  4. Clogged or dirty parts: Regularly clean and maintain your diffuser according to the instructions on the manual. Use a soft brush or cloth to gently remove any buildup or residue. You can also soak the parts in a cleaning solution for a few minutes before rinsing and drying them.
  5. Power source: Check if the batteries are fresh and fully charged, or if the outlet is working properly. If you’re using an extension cord or power strip, try plugging the diffuser directly into the outlet to see if it makes a difference.

Maintenance and Prevention Tips

To prevent low mist output and other problems, here are some maintenance and prevention tips:

  1. Use distilled water or filtered water instead of tap water or hard water.
  2. Clean your diffuser regularly, at least once a week or after every use.
  3. Avoid using harsh chemicals or abrasive materials to clean the diffuser.
  4. Replace any damaged or worn-out parts, such as the ultrasonic plate or nozzle.
  5. Store the diffuser in a safe and dry place when not in use.


Sure, here are some possible answers to those questions:

Why is my diffuser barely misting?

There could be a few reasons for this. First, make sure that the water level in the diffuser is adequate and not below the minimum line. If that’s not the issue, try cleaning the ultrasonic plate inside the diffuser, as buildup or debris can interfere with its ability to create mist. You can use a soft cloth or cotton swab dipped in rubbing alcohol to gently clean the plate. If neither of these solutions works, there may be a problem with the diffuser’s motor or other internal components that require repair or replacement.

Why is my diffuser not making my room smell?

One common reason for this is that you may be using low-quality essential oils that aren’t potent enough to be detected by your nose. Try using a higher-quality oil or a different scent altogether. Additionally, make sure that you’re using the correct amount of oil for the size of your diffuser, as using too little can also result in a lack of scent. Finally, check that your diffuser is working properly by verifying that mist is being produced.

How do you fix a clogged diffuser?

If your diffuser is clogged, the first step is to turn it off and unplug it. Next, carefully remove the cover and check for any visible blockages or buildup on the ultrasonic plate or other parts. You may be able to gently clean these areas with a soft cloth or cotton swab dipped in rubbing alcohol. If the clog is more severe, you can try running a mixture of water and vinegar through the diffuser to dissolve any mineral deposits or other debris. After cleaning, rinse the diffuser thoroughly and let it dry completely before using it again.

Why is my White Company diffuser not misting?

If you’re experiencing issues with a specific brand of diffuser, it’s always a good idea to consult the manufacturer’s instructions or customer support resources. However, some possible reasons for a White Company diffuser not misting could include insufficient water levels, a clogged ultrasonic plate, or a malfunctioning motor. Try troubleshooting these issues using the steps outlined above, or contact White Company customer service for additional assistance.


Low mist output from a diffuser can be frustrating, but it’s not a lost cause.

By understanding the possible causes and solutions, and by following some simple maintenance and prevention tips, you can enjoy your diffuser’s benefits for a long time.
