Advantages and Disadvantages of an Ultrasonic Humidifier

Ultrasonic humidifiers are quieter and require less maintenance than evaporative models. However, they can propel minerals into the air that may cause respiratory issues. This is especially a concern for infants and young children.

The good news is that these risks can be reduced by regular cleaning and disinfection of the device. In addition, distilled water should be used to avoid mineral buildup.

Energy Efficiency

The advantage of an ultrasonic humidifier is that it uses less energy than other types of humidifiers, which can help you save on your electricity bills. However, the efficiency of these devices can be reduced by mineral buildup on the piezoelectric transducer or the use of non-distilled water. To minimize these issues, regular cleaning and the use of distilled water are recommended.

Ultrasonic humidifiers utilize a ceramic diaphragm vibrating at an ultrasonic frequency to create water droplets that exit the device in the form of cool fog. They also utilize de-ionized water to ensure that minerals and potential pathogens from ‘dirty’ water are not dispersed into the air. These devices consume less power than steam humidifiers, which is why they are often preferred for use in homes and offices.

When choosing an ultrasonic humidifier, it is important to select one with a high energy efficiency rating. Look for ENERGY STAR certification, as well as the wattage that it consumes per hour. This will give you an idea of how much it will use each year.

Another important factor in determining the efficiency of an ultrasonic humidifier is its ability to produce a mist that is not too laden with particles. The particles can be irritating to the lungs of infants and small children, and may even cause breathing difficulties. Additionally, the particles can settle out of the air and onto surfaces before they have a chance to evaporate. This can lead to the formation of puddles and damp areas that can be difficult to clean.

Noise Levels

Most portable humidifiers are not completely silent, but ultrasonic models produce less noise than evaporative humidifiers. The noise produced by these devices depends on the size of the tank and the technology used to create a mist. In most cases, an ultrasonic humidifier produces about 30 decibels of noise, which is only slightly louder than a soft whisper.

The way these machines work is by vibrating a metal diaphragm that emits an ultrasonic frequency, creating water droplets that are then released into the air. The mist created by these machines is generally cool, but can also be warm if a heater is included in the model. Ultrasonic humidifiers are quieter than vaporative and steam humidifiers, which means they are suitable for use in bedrooms and children’s rooms.

Humidifiers that do not use a fan to create a mist are more prone to bacteria growing in their tanks and then being expelled into the air, which is why it’s important ultrasonic humidifier manufacturer for them to be cleaned regularly. This can be done with a simple damp cloth or by using a disinfecting solution.

Regardless of the type of humidifier you purchase, it’s crucial to read the manufacturer’s instructions carefully and follow them closely. Doing so will help you avoid mineral buildup, which can clog the machine and increase the noise levels it produces.


Humidifiers require periodic cleaning and disinfection to prevent bacteria, germs and other undesirable microorganisms from building up. This is particularly important for ultrasonic and impeller humidifiers that disperse water droplets into the air. According to the Consumer Product Safety Commission (CPSC), these particles can contain microorganisms, minerals and other pathogens that can cause irritation to the lungs of those who breathe them.

It is recommended that you clean your humidifier at least once a week or more. Be sure to empty the tank and wipe down all surfaces inside of the machine, and be sure to follow your manufacturer’s instructions for ultrasonic humidifier supplier using cleaning agents or a disinfectant such as a 3% solution of hydrogen peroxide.

A blocked diaphragm can occur when a humidifier isn’t cleaned frequently enough, and this can cause the device to stop producing mist. The blockage can be caused by a number of substances including insects and dust, so it’s important to keep an eye out for these problems and clean the device regularly.

You should also be sure to check your humidifier regularly to see if it has a filter or other parts that need to be replaced. Review the instruction manual to find out how often you should replace these parts, and be sure to clean them thoroughly when it’s time to do so.

Water Requirements

In ultrasonic humidifiers, a diaphragm vibrates at an extremely high frequency to propel microscopic water droplets into the air. The water droplets then evaporate, adding humidity to the room. The lack of heating involved makes these types of devices more energy efficient and safer than evaporative ones, which use hot steam to add moisture to the air. They are also quieter than other types of humidifiers.

Many manufacturers recommend using distilled or demineralized water in their humidifiers to avoid mineral build-up and potential health risks. This is because tap water contains minerals that can be dispersed into the air when the mist evaporates, leaving white dust on surfaces and inhalable by people in the room.

These mineral particles can cause lung irritation and irritant reactions in some people. Although long-term studies haven’t shown a link, it is best to use demineralized or filtered water to reduce the risk.

Some ultrasonic humidifiers are designed to be connected to a drain, so the excess minerals can be disposed of. Others are drain-less and recirculate the water, but they require periodic manual cleaning to remove mineral deposits from the humidifier’s interior. If you choose a model that requires connection to a drain, look for one with an automatic shut-off when the tank is empty or low on water.
