Are Dyson humidifiers ultrasonic?

Dyson is a popular home appliance company that offers portable humidifiers that don't just increase moisture but also purify and cool your indoor air while you're using them. They are what the manufacturers call hygienic humidifiers as they trap pollutants so that they won't circulate in the air anymore.

Dyson humidifiers also come with other great features such as the remote control, voice services, and the Dyson link app. They have sensors that measure the temperature and moisture levels and detect the pollutants in the air.

Unwanted particles are captured while the system provides purified and humidified air in the room. They also cool the air as needed.

When buying these devices, it is also essential that you know which type of humidifiers they are. Knowing this information will let you know what to expect when it comes to their operation, maintenance, appearance, noise level, among other factors. This will influence your decision on which humidifier type to buy.

Dyson Purifier Humidify+Cool and Dyson Purifier Humidify+Cool Formaldehyde are evaporative humidifiers. These are re-engineered purifier humidifiers that make use of advanced evaporative technology to add moisture to the air. They automatically maintain the optimal moisture level in a given room to provide a more comfortable environment.

They have a biostatic woven mesh evaporator with disposable filters which are then soaked in the water tank. The air that is pulled into the humidifier converts water in the evaporator into water vapor.

But before the water vapor is released into the air, it passes through pipes with built-in UV light that kills 99.9% of the bacteria found in the water. This is how your indoor air is purified and humidified. The fan feature is optional. You can use it as needed.

Evaporative Vs. Ultrasonic Humidifiers

Humidifiers increase the moisture level in a room so that it isn't too dry in there. Dryness of the air can make you uncomfortable and cause skin, eye, nose, and throat irritations. It can also cause lung and other respiratory diseases.
Nowadays, humidifiers are increasingly important because they help relieve symptoms of flu and colds. They also help moisturize your hair and lips, which is a huge relief, especially during winter. These devices also help prevent allergies and asthma problems.
When it comes to homes, having the optimum humidity level will help make you feel more comfortable. It will protect your wooden furniture, floors, and walls from cracking. It will also help your plants to thrive if you're keeping them indoors.
That's why more and more people are considering getting portable cool mist humidifiers for their homes. There are two main types of these devices that you can find in the market: evaporative and ultrasonic humidifiers. Let's discuss how they work in detail as well as their respective pros and cons.

Evaporative Humidifiers

These are the most common humidifiers on the market. The main components of these devices are a water reservoir, a fan, and a wick filter.

The wick filter absorbs water from the reservoir while the internal fan pulls the indoor air into the humidifier. What we now have at this point is damp air that is released in the room, whether by spraying or as water mist.

The device will continue doing this until the desired humidity level is reached. The fan is a crucial part as it hastens water evaporation and quickens the amount of time needed to increase the humidity in the room.

Evaporative humidifiers are considered one of the safest ways to increase the moisture level in a room since they do not use heat to keep the air circulating. You can use them even when you have babies and pets in the room.

They also produce fewer white discharges into the air when operating. This is made possible by the filters that trap pollutants from the air. These devices also come with a more affordable price tag compared to other kinds of humidifiers.


This type of humidifier has a bulky appearance because of its components. The wick filter alone can be quite huge aside from the refillable water tank.

The filter also requires routine maintenance to prevent the accumulation of dirt and bacteria. If you use tap water, you'll be replacing your filter more often than when you're using distilled water.

Since these devices use fans, you can expect some noise during their operation. The noise level would vary depending on the humidifier's design and the size of the fan that it's using.

Ultrasonic Humidifiers

This type of portable humidifier makes use of a pressure transmitter either in the form of piezoelectric transducers or ceramic diaphragms to convert the electrical charges around them into energy. They use ultrasonic frequency to produce fine water droplets that are expelled into the room.

More plate vibrations produce more mist which means more moisture or higher humidity in the air.

These humidifiers are available in various cool and fun designs and sizes. There are some that come with refillable tanks, while some can be placed directly into a glass of water so that they'll have a water source.

Since they don't use fans, they operate quietly, so you won't be bothered by any noise while you're humidifying your room. They also don't have filters. This means that you don't have the added task of replacing dirty filters every now and then.


These humidifiers are relatively more expensive than evaporative ones. They are also notorious for emitting gray or white dust into the air since they don't have filters to trap these particles. These pollutants can settle on the furniture and other stuff inside the room. They can also induce asthma and allergy symptoms.

The buildup of mineral deposits on its surface can cause scaling and might be difficult to remove in the long run. Once they harden, they can also block passages and affect the humidifier's performance.

The Verdict

Knowing the pros and cons can help you decide better which kind of humidifier will work best for you. If you're not bothered by having to replace the filters every now and then, evaporative humidifiers are better in ensuring that the air is not just made moister but also cleaner and healthier to breathe.

Does Dyson humidifier need distilled water?

You can use tap or distilled water in your Dyson humidifier. But take note that if you use tap water, you might encounter possible issues as it may contain pollutants and water-borne bacteria that can affect the quality of the air that's released by your humidifier.

This also applies when you use mineral water in your reservoir. It contains mineral deposits that can accumulate on the device and affect its performance.

This is why experts recommend that you use distilled water in your humidifier. It doesn't hold any contaminants and minerals that can get in the way of your humidifier.

When you use distilled water, you won't have to replace your filters as frequently as when you use tap water. It also doesn't encourage the buildup of bacteria, mold, and unwanted odors; that's why the air you breathe is much healthier.

Does a Dyson fan reduce humidity?

The Dyson Purifier Humidify+Cool and Dyson Purifier Humidify+Cool Formaldehyde models have the combined capability to purify, humidify, and cool the air around you. They are considered an advanced hybrid machine so that you can enjoy all these features in one appliance.

Its fan swings at three different degrees of oscillation - 0, 45, and 90 degrees. It imitates natural airflow so that users can enjoy a cool breeze in their homes.

As long as you enable the cooling and humidifying features, Dyson fans won't reduce the humidity level in your room. These devices have been programmed to automatically adjust the humidity in the room according to the optimum level.

Final Thoughts

As evaporative humidifiers, Dyson humidifiers make it easy for us to improve the moisture level in our rooms which benefits us in so many ways. They also provide us with the added bonus of making sure that the air we breathe inside our homes is cooler, fresher, cleaner, and healthier.
