Difference Between Warm And Cool Humidifier – Pros & Cons

On hot summer days, a cooling air conditioner is a great choice for many families. However, because the air conditioner has the ability to cool deeply and quickly, it will absorb a certain amount of moisture, causing the skin to become dry and the air to be unbreathable, and users to have a dry throat, dry nose, and especially respiratory diseases such as acute bronchitis, pneumonia,…

Similarly, when the weather is dry, the low humidity of the air will cause such phenomena. To overcome this problem, the solution is to use an air humidifier to maintain adequate humidity for the whole room.

Still, there are many types of humidifiers. This article today will talk about the difference between warm and cool humidifiers, pros and cons of each type, and their usage. Scroll down to know!

What is a Humidifier?

A humidifier is a machine that is used to make the air in your room less dry and thus, alleviate the discomfort caused by skin dryness, allergies, sinuses, and asthma. Hence, they will emit water molecules into the air to make the humidity increase.

Almost all of the common humidifiers on the market today operate on the principle of using high-frequency ultrasound to turn water into nano-sized steam particles and blowing them into the air in the form of fog to increase room humidity, bringing a very comfortable feeling.

Why You Should Use Humidifiers

Comfort

For rooms using air conditioning, the humidity is often much lower than the environment outside the room. In the dry days, the humidity is also very low. Therefore, we often have dry skin, dry throat because the body is dehydrated in these conditions. Using a humidifier will provide reasonable humidity for the room, which is good for breathing, especially children, the elderly or people with weak airways, chronic diseases like asthma, sinusitis, allergies,…

In addition, some humidifiers also equipped with air filters, helping the air in the room to be free of dirt, so it is good for health.

For rooms that do not use air conditioning, a humidifier is usually combined with a fan to help reduce the room temperature quickly in the hot days, bringing a cool, more pleasant atmosphere.

Electronic Devices Protection

In the winter, when humidity is low, static electricity occurs more often. Static electricity usually does not have too much influence on people’s daily activities. However, for electrical equipment, static electricity is quite a big problem.

It will cause the phenomenon of electric discharge, which can cause damages to the components of electronic devices. In the worst case, an electric discharge can also lead to fires.

What is more, it also causes adhesion. Static electricity exists on the surface of objects. When reaching an appropriate limit, electrostatic fields will be created. Then, they will suck the tiny particles into the surface of the static electricity carrier. Therefore, the surface of the TV screens or computer monitors is often easy to get dust.

Longer-lasting Furniture

You may have seen your furniture in your house swelling and cracking in cold winters. Or even more, you are sitting on a fine chair and suddenly, it wobbles. Likewise, your paints and wallpapers are beginning to scale off although there is no water leakage.

This can be attributed to the low humidity, which affects the structures and the luster of your furniture, shortening their lifespan.

Differences between Cool and Warm Humidifiers

To increase the humidity level in your house, people can use warm humidifiers as well as cool humidifiers. Although they all produce the same results, they are still different from each other, mainly in the ways they achieve.

Cool Humidifiers: Pros and Cons

As the name suggests, the cool humidifiers are used to create cool mist, releasing it into the air and easing the hot, dry climates. On the market, they mainly encounter 2 types of cool humidifiers, including evaporative humidifiers and ultrasonic humidifiers.

Evaporative Humidifiers

There are 3 main parts in this type, which are a wick/filter, a fan, and a water reservoir.

A wick, also known as a wick filter, is used to take water from the reservoir. At the same time, the fan is activated, simultaneously vaporizing and cooling the water across it. Then, the fan will take the responsibility of blowing all of the moistened air out into the environment.

Pros

The evaporative humidifier is a cool humidifier, so it is able to cool down the room, making it ideal to be used to hot weather. For some households that do not use air conditioners, a cool humidifier combined with a fan is also used to reduce room temperature during periods of high temperatures. The higher the temperature is, the faster the vapor will be. In short, the temperature will decrease rapidly by 5 or 7 degrees.

Although it emits vapor, the vapor is cool. This means the product is safe enough to be put in the house with children or pets without harming them.

In the list of components of evaporative humidifiers, there is a wick which in fact is a filter. This filter will remove the waterborne impurities, making the moistened water fresher. Also, it will reduce your cleaning workload.

What is more, you can add some inhalants in the water reservoir. These inhalants can act as a solution to cold or flu.

Cons

However, the drawback is that it uses a fan, so it is a little noisy. Hence, it is not recommended to be put in bedrooms or baby rooms.

In addition, due to the mechanism, it creates large-sized water droplets, and thus, it is harmful to nearby electronics in the home.

Moreover, the steam created in the cold season also makes the body feel colder than usual, accompanied by an uncomfortable feeling.

Ultrasonic Humidifiers

Ultrasonic humidifiers are devices that can create ultrasonic waves to separate water or mixtures of water with essential oils into tiny particles and release them into the environment in the form of thin mist.

The ultrasonic humidifier is equipped with an electronic circuit board that can use electricity to generate ultrasonic waves. When the water is exposed to ultrasonic waves, it will be split into steam mist form, and then pushed to the external environment.

Pros

Ultrasonic humidifiers are increasingly used thanks to the great benefits for human health.

Balancing room humidity: Users often combine the humidifier with an air conditioner to increase the cooling effect. This reduces the dehydration of the body, preventing respiratory diseases and chapped and dry skin,…

Dispersing essential oils into the air: It can increase the effectiveness of essential oils in eliminating odors, repelling insects, creating the fragrance,…

Additional features: Some high-end ultrasonic humidifiers are also equipped with dust filter dust, disinfection,… to make the air fresher and protect the user’s health.

Cons

As users often use tap water containing mineral molecules, hard metals such as calcium,… the device easily creates deposits. In the long term, accumulation can become a wonderful environment for bacteria, causing many hygiene-related diseases.

Warm Humidifiers: Pros and Cons

This warm humidifier uses electricity to generate heat to boil the water to the evaporation temperature, and the steam will be released into the air by the built-in components.

Pros

Thanks to the humidification by boiling water, the moisture will be safer because the high temperature helps kill most of the common bacteria that can be present in the water.

Furthermore, they can also avoid infection or allergy symptoms due to unsafe water sources.

When living in the dry air environment in the long term, the skin will wither, and even cause acne for sensitive skin. It can be seen that humidifiers, especially warm humidifiers, have a great impact and help women to maintain the beauty of the skin. Some quality humidifiers not only help replenish moisture in the air but can also let the steam penetrate into the skin to make it healthier and smoother.

For those who have a weak respiratory system such as children, the elderly, and people with respiratory diseases, chronic diseases such as asthma, respiratory infections, sinusitis,… they will definitely enjoy the best health benefits when using a warm humidifier.

Cons

This type may cause burns if we, unfortunately, break it or touch the valve. Families with small children aged from 1 to 3 should not use this device because of this risk. However, if needed, you should find a suitable place to place the device such as on high tables.

Improper use of the warm humidifier will facilitate the growth of bacteria, mold, and pathogens. This is true because when the air is saturated if you add a bit more moisture to it, it will become a good environment for the “dangerous creatures” to grow, not only making the air unhygienic but also causing respiratory illnesses for family members.

Frequently Asked Questions

Which is Better for a Cold?

The air conditioner is one of the best cooling equipment today. It can reduce the temperature quickly, giving a pleasant feeling to the user. However, the air conditioner also has certain limitations. When operating, this device will absorb moisture in the air, making the air drier. If you regularly sit in an air-conditioned room, you are at risk of dehydration, dry skin, and more susceptible to respiratory illnesses. The most common disease you can catch is cold.

To overcome this problem, many experts recommend using air conditioners with humidifiers such as warm humidifiers. Besides health protection benefits, using a humidifier in the air-conditioned room also helps to save energy and reduce the “pressure” of working for the air conditioner.

One study even shows that a humidifier may reduce the risk of cold. After putting the cold virus in the air, the researchers found that air with humidity above 40% stopped the activities of the virus quickly. This will make the virus less likely to spread, thereby helping you prevent the cold.

Even more, warm humidifiers also allow users to add some inhalants and then disperse them into the air. In the end, they will help to relax the airways and relieve heavy congestion.

Which is Better for Allergies?

In fact, both warm and cool humidifiers can help you prevent allergies. Balancing moisture in the air is a simple and effective way to reduce allergy symptoms. People who suffer from sinus or airway dryness, which are more likely to develop an allergic reaction when they encounter dry air, can also reduce their symptoms by using a humidifier.

However, everyone should maintain a moderate humidity level, avoiding abuse. According to the US Environmental Protection Agency (EPA), the ideal indoor humidity level is from 30 to 50%. Excessive humidity (over 60%) can lead to difficulties in breathing and make allergy symptoms get worse.

What to Avoid when Using a Humidifier

Capacity

To choose the right humidifier, users also need to pay attention to the capacity of humidifiers, which is often specified on the label by the manufacturer.

Do not buy larger capacity than necessary because it is easy to cause excess steam, condensation on devices. During the winter, users need to set a slightly lower humidity level than the summer to avoid feeling cold.

Humidity Level

Excessive humidity will create favorable conditions for the growth of mold. Therefore, you should not use a humidifier continuously. Instead, only provide just enough moisture. If you see the glass on the window beginning to fog, an indication of saturated moisture, please turn off the humidifier.

Or you can use a hygrometer to check and monitor the humidity in the room most accurately.

If possible, choose models with smart features of automatic timer or controlling system, which can be adjusted to the humidity of the environment.

Water Storage

Humidifiers often need to store water in reservoirs, so people should clean them regularly and avoid long-term water retention as it can cause bacteria and mold to accumulate.

Rinse the water reservoir when adding new water. Do not use old water to prevent the formation of bacteria and mold inside the device. Also, do not leave the water in the reservoir for a long period if not in use. In the meantime, empty and dry it from the inside out.

Conclusion

When the weather is too dry or if you turn on the air conditioner in the room, the air will be lack moisture and thus, affect the skin, hair, and respiratory system a lot. So, deciding to have an indoor air humidifier will help you protect your health better.

Hopefully, through this article, you can know more about the difference between warm and cool humidifiers, pros and cons of each type, and some using guides.
