Humidifier Buying Guide

What Does a Humidifier Do? 

A humidifier is a device that expels water vapour into a room, increasing the water levels in the air, and consequently the humidity, opposed to dehumidifiers.  

Although there are many types of humidifiers, at the basic level they all emit moisture into the air, alleviating some of the ailments that come with cold weather, such as dry skin or chapped lips. 


Humidifiers come in a variety of types, each one with their own advantages and disadvantages. The main differences users will find is between cool mist humidifiers and warm mist humidifiers. 

Choosing the right one for you all depends on your own particulars and what you are using the humidifier for.  

Cool Mist Humidifier

A cold mist humidifier is the most common version of the humidifier on the market. As the name suggests, cool mist humidifiers work by releasing cool mist into the air, working as an air conditioner as well as a humidifier.

Along with their cooling properties, cool mist humidifiers are seen as great appliances for aiding swollen nasal passages, allowing you to breathe much better.

Cool mist humidifiers are generally easier to clean, more effective in larger areas, and better for users in warmer climates. 

The only downsides to cool mist humidifiers are the fact they tend to be noisier than other types, and the intricate filter system makes regular maintenance a must.      

Warm Mist Humidifier

Warm mist humidifiers work by releasing heated humidity into the air and raising the temperature of any room they are placed in. 

Warm mist humidifiers are noted for being able to treat chest illnesses such as coughs and colds, working by attacking flu-like viruses with heat.

Without the need for a fan, warm mist humidifiers are far quieter than their cooler counterparts.

The mist that is produced by warm mist humidifiers is also seen as far cleaner than the cool mist design. 

As the water is heated, this type of humidifier requires far more cleaning, eliminating the chance of mould or algae growing inside the heated moisture.

Be careful not to leave a warm mist humidifier around young children, as the heating elements of the device may cause burns to delicate skin.    

Ultrasonic VS Evaporative

Alongside the differing temperatures, humidifiers are again divided into two separate categories, ultrasonic and evaporative.

An ultrasonic humidifier uses a nebuliser, which is a metal diaphragm that vibrates much like an electronic speak would. 

This vibration sends out ultrasonic waves, creating water droplets which are then expelled into the air via a fan. 

These types of humidifier tend to be almost silent, making them more appealing to those who want to be unaware of the unit. The ultrasonic humidifier is designed without a filter attached to the unit; this saves operation costs but also increases the chance of white dust accumulating around the room.

An evaporative humidifier is the more common of the two and works on a more simple process. A fan draws cool water over a moist wick filter and blows it into the surrounding room. 

Because the evaporative humidifier has a filter, less white dust is accumulated with a sort of device. Evaporative humidifiers are more likely to be bulkier in appearance, as they contain far much more moveable parts including a fan and wick.

The noise levels on evaporation humidifiers can become an issue for some users, especially if you are placing it in the bedroom. 

As the mechanism works with an internal fan, noise levels can not be completely eliminated from evaporation humidifiers.   

Overall, choosing between the two different types completely depends on what you value more from a humidifier design. 

If affordability is higher on the list and little maintenance isn’t a problem then opting for an evaporative humidifier is best. 

If a quieter unit and low maintenance are more your thing, then it is worth paying that little extra and selecting an ultrasonic humidifier.


Deciding where to place your humidifier is key to getting the best out of the device. Knowing where to put it all depends on what room you are in. 

It is imperative that you match the size of the room with the size of the device.  If you are placing your humidifier in a large room, a small device will simply have no effect, and the humidity will be instantly lost. 

The same is true for a large device in a small room; the moisture will be overwhelming and even a detriment to your health.     

If we take a bedroom humidifier, for example, then placing the humidifier close to the bed is your best bet as the moisture and cleansing properties will be felt instantly while sleeping. 

If you are using a warm mist humidifier, however, place the device a little further from the bed as boiling water is safer at a distance.

When thinking of placement with a living room humidifier, it is often best to place the device where you and your family spend most of the time. 

The health benefits will be far better received when the humidifier is closer to its users. 

If you are using a humidifier for a young child or even a baby’s room, the placement of the unit should be done safely. 

It is not advisable to purchase and use a warm mist humidifier if you are placing it in a baby’s room, as the chance of burns from the boiling mechanism is heightened considerably.  

Humidifier Uses

Humidifiers are primarily used for their health benefits, especially when it comes to respiratory and skin based ailments. 

The reason for this is the moisture it creates in the users surrounding area, particularly when the natural climate is one of cold and dry. 

Many ailments and illnesses are far more prevalent during the colder autumnal and winter months. When the climate is colder, the atmosphere is far dryer. 

This dry cold climate opens up people to be far more susceptible to skin and respiratory illnesses. 

By changing the room’s atmosphere from cold and dry to warm and humid, the humidifier reduces the chance of some illnesses.        

Humidifier For Dry Skin

Those who experience particularly dry and itchy skin may benefit from using a humidifier in their home. 

When the outer layers of a person’s skin are dehydrated, then moisture and water loss is increased dramatically, causing the skin to dry and crack.

With a humidifier placed in a room, moisture levels can be kept at a beneficial high, while at the same time heating the room. 

The humid room will keep the skin moist and supple, stopping it from drying out. Although the health benefits for dry skin are widely known, if you suffer considerably high levels of dry and irritable skin, discuss using a humidifier with your doctor before you choose this course of action.  

Humidifier For Cough

One of the most common humidifier uses is for more respiratory illnesses such as coughs and colds. The theory behind this use is the cool, moist air loosens airways, making it easier to breathe. 

It is important to factor in the cleanliness of your device and the water if you are choosing to use a humidifier for this purpose. 

As the moist, humid environment of a humidifier is the ideal place for mould, bacteria, and fungus to grow, cleanliness is key. 

Breathing in harmful fungus and bacteria while you already have a cough or chest infection could be deadly. 

It is good practice to use distilled or demineralised water in your humidifier, rather than water from the household tap. 

This prevents mineral deposits from forming in the humidifier and causing more respiratory problems than before.


Choosing the right size humidifier all depends on the size of the room you are trying to humidify. Choosing the wrong size at an early stage can have unwanted effects further down the line. Opt for a small humidifier if the room you’re using it in is small. Using a large humidifier in a small room will cause an excess of moister in the air, something that can lead to mould growth and even ill-health.

Each humidifier model usually gives a reading in square feet of how much space it can humidify in 24 hours. If you only require the humidifier for one room, a tabletop or a portable humidifier is often more than up to the job. Whichever size you choose to buy and use, always monitor your humidity levels, keeping it at a safe and optimum level.         


Humidifiers are generally divided into two subcategories, whole-house and portable. A whole-house humidifier is built into a pre-existing furnace or air conditioning system.

A portable humidifier, on the other hand, is a device that can be moved around, room by room. 

Freestanding portable humidifiers have their own water supplies, usually on wheels, and plug into the houses mains electrics. 

Maintenance is the drawback when it comes to portable humidifiers, and the refilling of water supplies is usually a daily task. 

Many of the portable humidifiers have removable tanks, yet some you have to bring the water to the machine.

The compact nature of a portable humidifier means that no more than a litre or two of water can be placed in at any one time, meaning a constant refilling is needed.  

Humidity Level

Humidity levels must be monitored throughout their use, ensuring that levels are both optimum and safe. The optimum level of humidity in a room should be between 30% and 50%. 

Many models of humidifiers come with a built-in humidity gauge, if yours is without this built-in gauge, then purchasing a hygrometer is a necessity.

Having a humidity level that is too low will make the purchase and use of the device pointless. 

Having a humidity level that is too high can mean an undesirable level of moisture in the air and can cause issues such as mould or bacteria growth. 

Pricing Range

When it comes to humidifiers, the pricing range can differ hugely. 

Starting under $100 right up to the four-figure numbers and beyond. Purchasing a cheap humidifier may not break the bank, but it will mean its capabilities and performance levels might limit you.

At the lower end of the scale, humidifiers are often temperamental and prone to short life spans. 

If you are serious about achieving a good level of humidity and keeping your device in working order for longer than a year or two, it is advisable to splash out a little more.
