What are humidifiers?

A humidifier is a device that increases humidity in an area. At home, you can usually see them in a single room, unless you have a whole-home humidifier.

There are two types of humidifiers: cool-mist and warm-mist humidifiers. With the cool-mist humidifier, a fan moves air past a wick full of water. The water evaporates into the air. Having a cool-mist humidifier is a must, especially during the summer.

A lack of humidity can cause irritation on the skin, eyes, and other areas of the body. Dry air can also result in cracks in the house, such as in the drywall and plaster. Thus, you definitely should not preserve the dry air in your house, so it is suggested to have a humidifier.

Raising the humidity in your home to 40% can improve skin and hair health, can diminish snoring symptoms, and can keep wooden furniture, floors, and musical instruments in pristine condition.

How do diffusers work?

A nebulizing diffuser sprits the essential oils into the room straight away without the use of a humidifier. It uses both a cold air pump and a spritzer to atomize the oil into tiny particles of vapor. The micro vapor comprises tiny droplets of the essential oil only. No heat is used in this process.

However, using a cool-mist humidifier for dissolving essential oils is certainly better than using a warm-mist humidifier, since the warm air can destroy oils’ therapeutic features. There are some cool-mist humidifiers that are designed for this purpose, like the Crane humidifier.

By adding a fragrance diffuser and a special mister, the humidifier holds the oils detached from the main tank and mists them into the air. If you purchase one of these, follow the manufacturer's instructions for using the mister and keeping the humidifier clean.

If you want to use essential oils as vapor, you should probably invest in a diffuser.

Other Questions


Is a diffuser the same thing as a humidifier?

Diffusers and humidifiers are often confused with each another because of their external appearance and similar functions. But there are distinct differences which sets them apart. The principal purpose of a humidifier is to moisten the air while the diffuser is used for adding fragrance to a room.

Though both products use water for functioning, the humidifier uses it to increase the humidity levels in a room while the diffuser uses it to disseminate essential oils into the atmosphere. Humidifiers help in relieving discomforts related to dry skin, stuffy nose and scratchy throat, while the benefits of a diffuser is limited to aromatherapy only.


How much essential oil do you put in a humidifier?

Besides its primary function, a humidifier can also provide aromatherapy with the use of essential oils. This creates a pleasant atmosphere with therapeutic effects as the oil contains healing properties. I do not recommend it to use oils in regular humidifiers, as it may shorten the lifespan of the device and make it look very dirty.

The aroma humidifier comes with a special container to hold essential oils. This facilitates the evaporation process without contaminating other parts of the device. The recommended dosage is around five drops per every 15 square meters of the room. Humidifiers with essential oil trays must be cleaned and disinfected regularly to prevent the growth of mould and fungus.


Can I put essential oil in my Vicks humidifier?

Adding essential oils to a regular mist humidifier like the Vicks model is not a good idea because of many reasons. All Vicks humidifiers come with a water tank specifically designed for water only. Adding oils could damage the unit's inner components severely, making it useless and exposed to shock and fire hazard.

It may also wear off the plastic. If the humidifier stops working upon adding essential oils, you may end up purchasing a new one which could be more expensive as the warranty may become void depending on what it offers. Majority of the humidifiers depend on heat for generating vapour that is emitted into the air. As far as this process is concerned, heat is among the greatest enemies of essential oils.
