Why Choose Warm Mist Humidifiers?

When shopping for a humidifier, you have a choice between warm mist and cool mist technology. Cool mist humidifiers typically force particles of water into the air with a fan, adding moisture to the environment. Cool mist humidifiers are typically adjustable in many ways, including the direction in which the mist flows and the amount of output (based on a knob setting).

By contrast, warm mist humidifiers utilize a heating element to create vapor by heating or boiling the water in the unit. The vapor is typically released without a fan, since warm air/particles rise, giving it a more natural and quieter entrance into your home atmosphere. Both types of humidifiers employ multiple technologies to achieve their goals, and it’s important to consider these technologies when making your purchase since your individual needs and preferences can greatly impact the best option for you and your home or large rooms.

Warm mist humidifiers have several advantages to consider, including the cleanliness of the unit. Because the water is boiled before being released into your home environment, it’s highly purified, leaving allergens such as mineral dust, mold spores, and potential toxins like waterborne bacteria behind.

 A warm mist humidifier, also known as a vaporizer, also offers the distinct benefit of quiet operation so you and your family aren’t disturbed by the volume. Other benefits are included with some warm mist humidifiers, making them and even more valuable choice.

The only reason to not choose this type is the danger it can pose for baby. The hot water and vapour can spill or leak, causing burns. But if you’re careful, follow instructions, and never leave it unattended for too long, there’s no reason you can’t use them to help your child.

What is a Warm Mist Humidifier?

Employing specific technologies and various safety and overall ‘green’ or ‘clean’ features can really make a warm mist humidifier stand out above the rest. However, there are a few other reasons certain models rank at the top of the list, including tank size, settings capabilities, potential filters, and ease of cleaning. Take a look at some of the things we’ve identified as top features to rank a warm mist humidifier at the top of the list for satisfaction.

Technology

For most warm mist humidifiers, the technology used for operation is essentially the same. A heating element of some kind boils the water you put into the tank. Then, without other tools and counting only on physics, the warm mist – or vapor – is released into the space around the humidifier. But it’s the other technology available that could make or break the rating of the humidifier.

For example, having multiple settings available for overall functionality, including the amount of vapor being released. What does that mean? You can actually control the temperature and amount of mist released in many warm mist humidifiers, and these have an advantage over the competition because the last thing you need is for your humidifier to put too much moisture into the air.

Another technology feature is a shut-off feature that automatically turns the device off when the water level gets low or runs out. This is good for preventing damage to the unit from overheating and burning since it can’t operate properly without water. It also reduces the risk of that low volume causing some of the unwanted particles left behind from re-entering your atmosphere.


Convenience

Take into consideration that the boiling process used to create vapor in a warm mist humidifier is environmentally friendly and virtually allergen-free. It also removes harmful waterborne bacteria from the air you breathe, as well as preventing mold and other spores from causing damage to you and your family’s health.

So, in order to maintain this beautiful trade-off, you want a warm mist humidifier that’s easy to clean. Those spores and dust remain behind in the tank of the humidifier – or the filter, if you have one – so you need to be able to conveniently clean the tank and various parts of the humidifier on a regular basis. This may mean also having a humidifier without a filter, which can assist in streamlining the cleaning process so it’s less work.

Another convenience of the warm mist humidifiers is that they are often portable. Unlike some cool mist humidifiers, warm mist humidifiers typically aren’t made for whole house or even large area use. Therefore, even within a large room, you may want to place the humidifier in a different location depending on what you’re doing and what space in that room you’re occupying. Since there are fewer parts, warm mist humidifiers should be compact and easily portable from one place or room to another, both in weight and handling.

With portability comes versatility, preferably of location. In the past, many vaporizers were made to sit on the floor, but it’s crucial to keep your warm mist humidifier out of the reach of children and infants since the boiling water heats up the unit, which can lead to burns. The mist may also cause steam burns on small children. The mobility of the unit and an ability to place it on surfaces out of the reach of children is another bonus feature you should look for when purchasing warm mist humidifiers.

At the same time, the unit should also have a sufficiently large tank to run for at least 12 hours without having to worry about refilling it. No one wants to wake up in the middle of the night and have to add water to their humidifier, and if you can, you should look for a warm mist humidifier that will keep going for 24 hours so you can easily put the refill process on your schedule and do it once a day.


Virtual Silence

One of the biggest draws of a warm mist humidifier over a cool mist model is that, with cool mist, there is a fan driving the moisture into the air. That means there is always going to be background noise that can disturb your sleep or the sleep of a loved one, especially an infant. With warm mist humidifiers, you should expect a virtually silent experience, since there is no fan to speak of.

The only noise should come from the boiling process, and if you ever boil water in a kitchen, you’ll know it’s a virtually silent process. In humidifiers, the lower volume of water and the lower boil both reduce even that noise to the bare minimum.


Added Essential Oils

Whether it’s dual mist or not, some humidifiers have an extra benefit that allows you to use essential oils with the water in the tank to output a fragrance that can be beneficial to your health. Whether for aromatic and mood purposes or for health reasons – such as having a medicated menthol oil dispersed to help open up the lungs when you have a chest cold – this added feature can really increase the value of the product.

To make things convenient and easy, we’ve rounded up the 6 best rated warm mist models and their reviews.

The humidifier can also conveniently be used with liquid inhalants and includes a medicine cup for your convenience. Perhaps the only downfall is that, if your environment is particularly dry, and you have to run this humidifier on the higher setting, you could end up running out of water sooner than you like.

Conclusion

When shopping for a warm mist humidifier, it’s not enough to find a unit with all the standard features. You want something that’s going to give you options and work well in your personal environment. All warm mist humidifiers assist with relieving dry, irritated skin and lips, and they can all help keep sinuses clear and out of pain, especially during cold and flu season. However, they aren’t all made for the same space or the same personal needs. Consider how large of an area you want to moisturize before looking into warm mist humidifiers, so you can rule out anything that isn’t appropriately sized.

Also, take a look at the controls you’d like to have. Make sure your humidifier is adjustable so that you can control the output and direction of the mist, enabling you to suit it to the room in question. Think about whether or not you’d like it to incorporate a cool mist option for summer when you don’t necessarily want to warm the air any further. Determine if you would rather simply have a vaporizer with the steam output or if you’d like to include the ultrasonic technology for greater push and finer particles.

And finally, think about safety, and determine if you are willing to risk the humidifier running dry by not opting into a model with the automatic shut off feature. Once you’ve decided what specifications matter most to you, you’ll be able to choose the right model. When all is said and done, each of these models above is incredible, but for the best all-around performance, the Homedics TotalComfort Warm Mist Humidifier is probably the top pick, with almost every feature you could want and few questionable issues.
