I first came across humidifiers a few years back after suffering from repeated eye infections caused by dry eyes that would just not go away. I had tried everything recomhe number of positive features it has! Because it’s small, it would make a great portamended by doctors but the infections kept returning and it would get to the point that in order to be able to open my eyes in the morning, I was running to the bathroom to stick my head under the faucet! My problem was only resolved after a colleague recommended me having a humidifier in my bedroom overnight to prevent my eyes becoming too dry. I was skeptical I must admit, but I bought a humidifier and tried it out overnight for the first time. To my surprise, I could open my eyes when I woke up! They weren’t dry and irritated and I didn’t feel the need to rinse them. I was sold! Because my eyes remained moist overnight, I was also able to fight off the recurring eye infections and I’ve never had one since.So, for whatever reason you’re looking into getting an ultrasonic humidifier, this ultrasonic cool mist humidifier review will help you.

Why Is Humidity Important for a Healthy Life?
Humidity plays an important role in maintaining a healthy lifestyle. Its importance is often overlooked, or not known about in great detail. However, as your comfort depends on whether you feel too hot or too cold, it is really important to understand how humidity, as well as ambient temperature, affects your body.
If the humidity is too high, your body loses its ability to cool down through the production and evaporation of sweat. This can be pretty dangerous if prolonged for a long period of time as it can cause overheating. If overheating occurs, the body can suffer from heat stress or other problems with breathing or problems with the heart.
The answer, of course, isn’t to have low humidity either as this can cause its own problems. If there is not enough moisture in the air, your chance of catching a virus is increased. Firstly, this is because viruses survive longer in areas of low humidity. Secondly, when people with a virus sneeze in low humidity, the water droplets and nasal secretions they expel stay in the air for longer and are finer, which means that others can catch the virus more easily.
Low humidity also affects the body physically. For example, if the humidity is too low you can suffer from dry eyes because your tears will evaporate too quickly. The same goes for the skin. If moisture evaporates too quickly from your skin, it can make you itchy or you can have dry and scaly skin. This is often a problem during the winter months.
In terms of breathing and airways, low humidity can be an irritant. If the airways are irritated, they are more susceptible to catching an infection.
What are Humidifiers?
Before we begin to look at the best humidifiers, it’s important to discuss what their purpose is. First and foremost, however, we need to understand what humidity is.
Humidity is how we describe how much moisture, or water vapor, is in the air. It is not something seen by the human eye. It is usually talked about in terms of a percentage. For example, when the relative humidity is 100%, the air can’t possibly hold any more moisture, meaning that rain is more likely to happen.
Humidity affects people quite drastically. Human skin relies on the air to remove water from the body. We see this in the form of sweat. Sweat evaporates into the air to cool us down. In an environment with 100% relative humidity, sweat can’t evaporate and so the body doesn’t feel cooler. At the other end of the scale when humidity is low, we might feel cooler because sweat evaporates readily and cools us down. The most comfortable humidity for humans is somewhere between thirty and fifty percent.
Indoors, low humidity can cause problems. Low humidity indoors typically occurs in the cooler winter months when the air is dryer and temperatures are cooler. If the humidity in your home is too low, you may experience some problems. Low humidity causes the skin to dry out, including mucous membranes. This may cause you to experience dry skin, chapped lips or a dry throat in the mornings. Low humidity also makes the room feel cooler than it really is so you might end up cranking up the temperature and spending more money on heating. It actually costs a lot less to humidify a room that it does to warm it up. It’s important that a room isn’t too humid, however, as this can also cause problems such as increased dust mites, mold, and unhealthy bacteria.
People understood the benefits of room moisture as early as the 1930s. The first patent was granted in 1934 for a Gas Humidifying Device. Nowadays, there are lots of different types of humidifier available and the products have really evolved over time.
Although there are many different types of humidifier with different health benefits, they all work in a similar way. They all force invisible water vapor into the air in your room. Different humidifiers achieve this in different ways, which we’ll discuss below.
So, if you, or any other member of your household, suffer through the winter months, a humidifier might just help to alleviate and improve symptoms. Humidifiers are known for helping the following problems: dry skin, sinus problems (including headaches caused by blocked sinuses), dry throats, irritated and bloody noses, dry coughs and cracked lips.
Types of Humidifiers
As I mentioned above, there are many different types of humidifier available to purchase nowadays and the type that you choose depends on the type of water vapor you want to put into your room.
You will see humidifiers being referred to as warm mist humidifiers or cool mist humidifiers. Warm-mist humidifiers heat water until its scalding hot, then diffuse the steam it produces. Some even have filters that catch mineral deposits. These can mean an additional cost to the consumer as they will need replacing from time to time. Warm mist humidifiers are not great to have around young children as they can cause burns. Cool mist humidifiers use different methods to expel the mist into the room. There are three main types of cool mist humidifier: evaporators, impellers and ultrasonic. You will read more about these below.
- Central humidifiers: Central or whole house humidifiers are a permanent solution to controlling the moisture in your home and are built directly into your homes air conditioning or heating systems. This obviously comes with a higher cost, but you have the benefit of being able to control the humidity of your entire home. These also have the added benefit of not needing to be maintained in terms of filling with water; they are directly plumbed into your home water supply.
- Evaporative humidifiers: Evaporative humidifiers drive water vapor through a damp filter. They use fans to push the moisture into the air, increasing the humidity into your room. They are a cheaper solution than central humidifiers but only work in one room. They function with a wick system. The wick, which is made from paper, cloth or foam, draws water out of a reservoir in the humidifier. The fan blows over this wick and thus the air collects moisture.
- Steam vaporizers: These are electronic humidifiers that work by heating water before cooling it and releasing it into the atmosphere. Unlike impeller humidifiers, these aren’t particularly child-friendly as they can burn. They are the simplest and least-expensive humidifiers. They are, however, one of the most expensive humidifiers to run. A positive of the steam vaporizer is that you don’t need to worry about the purity of the water vapor in terms of bacteria or minerals.Check our review of the top 10 warm mist humidifiers for better understanding.
- Ultrasonic humidifiers: These humidifiers use ultrasonic vibrations to create tiny water droplets that are emitted as a cool mist into your room. They have versions that use cool mist and warm mist. The cool mist versions are great for young families as they don’t burn. They are also silent, which is a big advantage. Ultrasonic humidifiers don’t cost a lot to run. As with impeller humidifiers, ultrasonic humidifiers could have problems with stagnant water if they are not properly maintained. Some high-end models, however, have antibacterial functions and use UV light to kill harmful bacteria. You also have to bear in mind the mineral content of your water as this will be expelled as a white dust into your room. Again, some models have filters that can remove the dust so that it is not expelled into the air.
- Impeller humidifiers: Impeller humidifiers have high-speed discs that rotate. When they rotate, the discs throw water through a diffuser, which breaks it into tiny droplets that are then expelled into the air. These humidifiers are relatively inexpensive and, because they use a cool mist, they are child-friendly. They are similar to evaporator humidifiers because they are single units suitable for a single room. They don’t cost a lot to run but you need to be careful not to allow the water inside to get stagnant as this will cause harmful bacteria to be distributed into your room. You also need to be aware that impeller humidifiers will expel any minerals in your water into the atmosphere, which may be harmful. Some models recommend using distilled water to avoid this issue.
- Also, sometimes you may need a humidifier only for one room. Check out our review of the top 10 single/baby room humidifiers to know more.
Why Is an Ultrasonic Humidifier Better?
Ultrasonic humidifiers are some of the best humidifiers on the market. They can also be some of the least expensive too, which is great for those of you on a budget who wants a really good product. There are many advantages to ultrasonic humidifiers over other types of humidifier. Firstly, they are quieter than other humidifiers, particularly evaporative humidifiers, as they don’t have fans to expel the moist air into the room. If you have young children suffering from winter sniffles, they are ideal for increasing the moisture in their bedroom to give you a quieter night!
Ultrasonic humidifiers also have a great advantage in that you can choose warm-mist or cool mist versions. With a warm-mist ultrasonic humidifier, the humidity will rise quicker in the room because the mist evaporates faster. This type also feels more comfortable in areas with cooler winters.
In terms of cleaning, ultrasonic humidifiers are really simple to maintain and are a lot easier to clean than other types of humidifier, particularly if you use them with distilled water. If you don’t like having to change filters, then you will find an ultrasonic humidifier better for your needs. Some people believe that ultrasonic humidifiers can kill bacteria and fungi in the water thanks to their ultrasonic frequency. It is important to note, however, that this has never been proven.
Other types of humidifier, like evaporative humidifiers, don’t function as well when there is already a lot of moisture in the air. With ultrasonic humidifiers, this is not an issue because of the way they moisten the air with vibrating discs. So, if you want the humidity of your space to be on the higher side, then an ultrasonic humidifier might be the best humidifier for you. This might benefit people who have a lot of wooden musical instruments, wooden furniture or floors and expensive artwork that needs a moister air.
However, there are some disadvantages to ultrasonic humidifiers. The major flaw with these is that they are renowned for producing a white dust as a by-product. This dust comes from the naturally occurring minerals present in hard water and as well as being annoying to clean up, it can be particularly harmful to anyone with a lung condition, such as asthma. Using distilled water should minimize this problem, but this adds an extra challenge. You can distill water yourself at home but obviously, this is time-consuming.

Why is This Product Our Advanced Pick?
This product has the highest number of positive features, along with our Top Pick. It is, however, much more expensive and has a heavy price tag of $90.

This ultrasonic humidifier uses its sensors to monitor the humidity in the room and adjusts its humidification settings. It also has adjustable speed settings that you can control both manually and remotely.

In terms of warranty, this humidifier comes with 2 years’ manufacturer’s warranty. It has a really good rating of 4 out of 5, coming from over 1000 reviews.

Wrapping it Up
An ultrasonic humidifier is a great addition to any home suffering from the ill effects of low humidity and any one of the above products will certainly improve the moisture in the air in your home if the natural ways don’t work out for you. Choosing the best humidifier is down to personal needs and preference. You need to think about the size of your room and what functions you want your humidifier to have. Whatever your options, you can trust that these ten products are the top rated humidifiers available in 2018.
It is worth reading up about ultrasonic humidifiers to ensure you are happy with the safety of these devices so that you can choose one that is going to give you clean and pure air. Unlike other types of humidifier, ultrasonic humidifiers release a white dust into the air in your home. This dust is nothing more than the impurities and minerals found in the water. This dust can cause problems for those with weakened immune systems or existing respiratory problems. Using filters and distilled water can greatly decrease this issue.
Another safety issue to consider is the risk of electric shock. We all know that water and electricity do not mix, yet this appliance uses both. It is wise to always act with caution when filling the water tank and making sure you don’t touch it with wet hands. It is also important to keep children and animals away from the humidifier.
With these common-sense precautionary measures, there is no issue with using an ultrasonic humidifier. We hope that our ultrasonic cool mist humidifier review and buyer’s guide has helped you in your decision. If you are still undecided, our Top Pick is a great place to start or you can read our research report to see side-by-side comparisons of all of the products we tested.
