How Does It Work?

The benefits of a humidifier cannot be contested, especially when it comes to relieving the symptoms caused by low humidity. When the cold season approaches, nasal congestion, dry skin, itchiness are just a step away, and the best way to fight these symptoms is to increase the humidity level in your house. Unlike warm mist humidifiers, which boil the water to produce vapors that are further released into the room, cool mist humidifiers work more like evaporative coolers, using the warm air as the main catalyst for evaporation. Another method that is often found on these appliances is ultrasonic technology.

The process of turning the water into a refreshing cool mist is pretty simple, and once you’ve understood how these devices work, you will be able to better distinguish between the two types and make the right choice for your home. So, let’s take a closer look at the technology behind them.

Two Effective Technologies

The years of research and innovation produced two types of cold mist humidifiers, one that uses evaporation to release the mist and increase humidity, and one that implies a spinning disk driven by a performant motor which splits the water into microscopic droplets. Each of the two methods has its benefits and drawn-backs, but when it comes to their main purpose, the result is excellent.

Evaporative Humidifier

The three components that are found obligatory in this type of humidifier are the wick filter, the water reservoir, and the fan. Although the fan size and power may vary, and the filter can be either of higher or lower quality, the process is the same, implying the following steps:

  1. The reservoir is filled with water according to its volume and capacity.
  2. Once the device is turned on, the water is drained from the reservoir into the wick through a paper sheet or a cloth.
  3. The fan draws the warm air in the room and blows it towards the wick, activating the evaporating process that leads to a drop in temperature.
  4. The cold mist is then released into the room, increasing humidity and creating a refreshing atmosphere.

Often, evaporative humidifiers use filters to remove the particles and pollutants that travel through the air. Depending on the quality of the filter, they can capture bacteria, germs, viruses, pet hair, dust mittens, mold, mildew, fungus, and even odors or VOCs.

Ultrasonic Humidifier

Renowned for their whisper-quiet operations and efficiency, ultrasonic humidifiers cannot function without 3 main components: the water recipient, the nickel electrodes, and the piezoelectric ceramic disk. Here’s how the process follows:

  1. Once the recipient is filled with water, the device is turned on.
  2. The electric current crosses the 2 nickel electrodes and reaches the disk.
  3. As the disk is piezoelectric, it starts to vibrate at an ultrasonic frequency which breaks the water molecules, turning them into smaller particles.
  4. The mist is instantaneously transmitted through the air into the room, all at an inaudible level of sound.

Ultrasonic humidifiers don’t use filters, as the high vibration process is powerful enough to sanitize the air. However, water deposits such as minerals or chlorine are broken along with the water molecules and end up in the air. This fine powder is known as ‘white dust’ and, although it is not dangerous for your health, it tends to deposit on the proximal furniture. An efficient way to ameliorate this problem is to replace the tap water with distilled water or try to find milder water.


Whether you choose the first or the second variant, the most important benefit is the improvement it brings to your health. Cold and flu symptoms will be alleviated and allergies reduced. Plus, during the summer, the cool mist will refresh the air in your house and drive away a small part of the summer heat.
However, a cool-mist humidifier can also bring you financial advantages, and these include:

  • Low power consumption – it is designed to save energy, and many models include a timer, so you can set the optimal operation time.
  • Attractive prices – although variable, depending on the technology, options, and smart functions, the average price remains within reasonable limits.
  • Low maintenance – Ultrasonic humidifiers don’t use filters, so you won’t have to deal with extra expenses. Moreover, even if evaporative humidifiers use them, they are pretty affordable and last for many months, so the maintenance cost will remain low.


Cold mist humidifiers run on ultrasonic vibrations, a technology that provides effective results without consuming much energy, thus turning them into real money savers. Many of them are equipped with large tanks that are easy to fill and clean and can run for tens of hours without interruption. Furthermore, their main function is supplemented by many attractive features that increase their usability and turn them into genuine gadgets.
