Humidifier Making Noise: Causes and Solutions


Are you hearing unwanted noises from your humidifier? If your humidifier is making more noise than usual, you’re not alone. This is a common problem among humidifiers and could be due to mineral build-up, an internal fan that has started to wear out, a damaged fan, or other physical damage. Find out why your humidifier is making noise and what you should do to fix it here.

Quick Summary

Humidifiers are designed to provide a steady and comfortable level of humidity inside of a home. Over time however, many of them will start to make a loud noise. This can be both annoying and worrying. There are several potential causes of a loud humidifier, ranging from mineral build-up to physical damage. To help resolve a loud humidifier, it helps to understand the cause.

Mineral build-up on the ultrasonic transducer can be an issue over time. The transducer is what produces the mist in a humidifier. Unfortunately, the fine mist it produces can also contain minerals from the water supply. Those minerals can buildup and interfere with the transducer, causing the humidifier to make a loud noise.

Another potential cause is an internal fan wearing down. The fan is used to move air around the humidifier and provide even circulation. Over time, the fan can become worn and start making noise. A damaged fan can also add to the noise of a humidifier.

Physical damage such as a cracked base or body can also be a problem. Such damage could cause a sound or vibration to occur within the humidifier when the fan turns on. Fortunately, any physical damage is relatively easy to diagnose and repair.

A loud humidifier can be an alarming and annoying problem. However, it’s important to identify the cause and address it. Knowing the cause and taking the necessary steps to fix the problem can help you get back to enjoying a quiet atmosphere in your home.

Troubleshooting Humidifier Noise: Causes and Solutions

Noisy humidifiers can be not only annoying but also the sign of a bigger problem. If your humidifier is making noise, then you need to understand why, and how to address the issue. Knowing the different root causes and troubleshooting tips will help you understand the source of the problem and determine the best solution.

Mineral build-up on the ultrasonic transducer

The transducer in a humidifier is responsible for creating cold mist. It works by vibrating at a very high (ultrasonic) frequency. When minerals accumulate in the transducer, they can block the soundwaves, causing the humidifier to produce a loud humming or rattling noise. To address this issue, you should regularly clean the transducer.

The internal fan has started to wear out

Another common cause of a loud humidifier is the internal fan wearing out. Over time, the fan blades wear down, preventing the fan from creating powerful, quiet airflows. If this is the problem with your humidifier, then you should replace the fan to reduce the humidity noise.

A damaged fan

Another potential issue is fan damage, which can cause a loud rattling noise. Damage can be caused by various factors, including age, clogs, and incorrect fan installation. If the blades are slightly bent or obstructed, they may be emitting a louder sound than they should. To fix this problem, you should check the fan to make sure it is securely installed and the blades are in proper alignment.

Other physical damage to the device

Finally, physical damage to the device can also cause loud noises. Damage can occur if the device is dropped or bumped. When this happens, the internal components may become misaligned, causing the humidifier to make loud noises. If you suspect physical damage, then you should replace the entire unit.


If your humidifier is making noise, then you should understand why, and what the potential solutions are. Potential causes of annoying noises include mineral build-up on the transducer, the internal fan wearing out, a damaged fan, or physical damage to the device. Knowing the root cause will help you determine the most effective way to solve the issue.

Personal Experience

  Troubleshooting Humidifier Noise: Causes and Solutions

As someone with extensive experience with humidifiers, I can tell you that it’s not uncommon for a humidifier to start making noise over time. This noise is usually the result of mineral build-up on the ultrasonic transducer. These deposits create an imbalance in the vibration, resulting in an audible hum. Another reason for this noise could be an internal fan that has started to wear out or become damaged – further increasing the noise level. In some cases, other physical damages to the humidifier device can also be the source of the noise.

In my experience, these issues can be avoided by regularly cleaning and maintaining the device. Make sure to follow the manufacturer’s instructions for proper cleaning and maintenance to avoid mineral buildup and other damages. Additionally, be sure to replace the filter regularly as well – this will help to extend the life of your humidifier and keep it running quietly.
