Types of humidifiers for home

There are majorly two types of humidifiers out there which can be used inside your home. These are the warm mist humidifier and the cool mist humidifier.

Warm mist or steam vaporizer humidifier

It releases moisture into the atmosphere by warming or boiling water with a heating element. Due to the high temperature of the water, as it is boiled, this type of humidifier is less prone to infections and development of molds, but it is very unsafe because of the danger it creates if children or pets are in the home.  The device overheating or someone coming in contact with it accidentally could lead to burns. Overall Warm mist is better for cold

Cool mist or impeller humidifier

It also makes use of water but vaporizes it by using a wick filter or high-frequency vibrations. There are types of this humidifier, which are:

  • Evaporative type 

This creates mist by forcing air through a filter that is saturated with water, which is then blown by a fan into the atmosphere, therefore adding more moisture.

  • Ultrasonic type

They make use of high-frequency vibrations that breaks water into micro-particle droplets, which is then released into the atmosphere of the room. This type of humidifier is the quietest and should be used with distilled water to avoid minerals being released in the form of white dust into the room. If any other type of water would be used, then the device should have a filter system for prevention.

Cool mist humidifiers are the safest type for your room due to the lack of a heating element, therefore no overheating hazards, although they require frequent cleaning and are prone to micro-bacterial infection.

what size humidifier do i need for my bedroom?

The primary thing to take into consideration while choosing a humidifier is the size of your room. After knowing the size of your bedroom, you should look out for the device with the specification that matches your room size. These specifications are always indicated by the manufacturer i.e., the approximate square feet the device can cover efficiently.

Should humidifier run all night?

The answer to this question depends solely on your needs. If you don’t like to wake up to the stuffy nose and dry skin accustomed with the cold season, you can run your humidifier all night though there are risks involved.

Due to the risks, we advise you to purchase a humidifier with an automatic function i.e., it can be set to operate at a particular humidity level and goes off when atmospheric humidity goes beyond the level. This way, you wouldn’t have to worry about the room having too much moisture and being infested by mold.

It is best you avoid using warm mist humidifiers overnight, to prevent skin burns from overheating. Humidifier with a timer feature can also be used, allowing you to set a particular time for the device to come on e.g., 2 hours before your normal wake up time, if you are skeptic about leaving the device on throughout the night.

Qualities to consider in choosing the best humidifier for one room

  • Size:

As stated earlier, the size of your room should be known before purchasing a humidifier, in order to help you select the right size that would be efficient in your home. You don’t expect a miniature sized device to serve your 1000sqft, do you?

  • Automatic features:

The two automated features to look out for are the timer, auto-shutoff and the humidistat. The auto-shutoff ensures the machine doesn’t burn out when the water tank becomes empty by turning off the device. While the humidistat is an automatic control system that turns the device on and off in order to maintain a set humidity level, this comes in handy when trying to avoid the atmosphere becoming too moist. A timer is used to control the period the machine comes on and shuts off, and is also quite helpful.

  • Anti-microbial system:

This is an added feature that comes in handy when considering health benefits. It is set up with either a filter or ultraviolet light that kills most of the germs or bacteria that could be expelled with the mist.

  • Safety:

As discussed and explained earlier, we recommend you go for a cool mist humidifier type, as it is the safest for you.

  • Noise level:

Sometimes, the manufacturer states in the specification the amount of noise released by the device. Therefore, if you are easily disturbed and irritated by noise type during sleep, you should purchase a device with extremely low noise output. In our reviews, we would specify the noise level of each from a user experience. Generally, the ultrasonic mist types are the quietest around.

  • Price:

A humidifier that will be running in a single room shouldnt be as expensive a s those that will be running in a full house. So, it is very important to consider the less expensive humidifiers that would perform a its perfect function

  • Essential oil

Although not as important to everyone but having a humidifier that permit the usage of essential oil is an added advantage.

Final Verdict: Best Humidifier for Single room

we rate the Honeywell HCN350 Germ-Free Cool Mist Humidifier as the best type for single room, due to its ability to efficiently increase the moisture content of the atmosphere and numerous healthy features, keeping your room free from infections. It is also our best pick for the best cool mist humidifier for large rooms.

The Vicks ultrasonic cool mist humidifier comes out next for its cost friendliness and its lack of filters, saving you expenses. It also puts out a large amount of mist for its size and is well and truly capable of satisfying your needs.
