There is no denying the benefits of using essential oils for aromatherapy. They can boost your mood, help with sleep, or simply add fragrance to your space. If you regularly use a humidifier and want to add a beneficial scent, you’ve no doubt asked asked the question – can you put essential oils in a humidifier?
Do not put essential oils in a humidifier, unless your humidifier has a tray specifically for adding oils. Do not put drops of oil in the water tank. Essential oils can damage the humidifier and shorten its life. Oil droplets can also land on furniture, carpets and soft furnishings causing damage.
This article goes over how to use essential oils to add humidity and freshness to your surroundings and the benefits of humidifiers and diffusers.
Can You Put Essential Oils in a Humidifier?
If you’re wondering whether you can use essential oils in your ultrasonic humidifier, it depends on whether your device has an essential oil tray.
Some humidifiers can’t be used directly with essential oils. This is because essential oils are corrosive, so you can’t put them straight into the water tank.
Humidifiers with an essential oil tray in the water tank let you enjoy aromatherapy everywhere you go. Knowing about different types of humidifiers can help you better understand this question.
Types of humidifiers are:
- Warm Mist Humidifiers
- Cool Mist Humidifiers
- Humidifier and Diffuser Combo
Adding Essential Oils to a Warm Mist Humidifier
Since a warm mist humidifier uses boiling water to make mist, it is not the best way to diffuse essential oils. When heated (usually below a simmer), essential oils lose their aroma and therapeutic qualities.
Although you can add essential oils to a warm mist humidifier, it may damage the structure of the oil if heated. It changes the oil’s chemical composition, altering the scent and eliminating its therapeutic benefits.
Adding Essential Oils to a Cool Mist Humidifier
On the other hand, a cool mist humidifier is ideal for preserving the oils’ therapeutic effects and aromatic value. Regardless, it can damage the appliance in the process.
Essential oils can block the filters and fan components inside the humidifier. Without a complicated mechanical system that converts the oils into an invisible vapor mist, the oils might not be able to reach their full potential.
Also, putting oils in the water tank of your humidifier can cause it to wear out faster. So, whilst it is possible to open the tank and put essential oils inside, you should not do this.
Why Can’t You Use Essential Oils in a Humidifier?
Humidifiers work best with distilled water. Essential oils are usually corrosive because they are made up of different parts of plants, such as seeds, roots, rinds, etc. The average humidifier has a plastic tank, and essential oils tend to destroy it.
Essential oils also affect the humidifier’s fan mechanism, which may cause it to malfunction. Because of this, essential oils aren’t the best choice unless the humidifier is made for this purpose.
Can You Put Essential Oils in a Humidifier for Plants?
Some essential oils are incredibly helpful for plants. Oils such as neem oil, citronella, and tea tree help repel insects, whilst oils such as cinnamon has beneficial antifungal properties.
Essential oils are derived from plants, so diffusing other scents (in small amounts) won’t harm your plant, but won’t necessarily provide any benefit to your plants either.
The key is to only use a humidifier diffuser combo if you want to diffuse essential oils in your plant humidifier. Plant humidifiers are no different to room humidifiers – you should not place any oils with the water.
Choosing a Humidifier and Diffuser Combo
If you want humidify the room and use essential oils for aromatherapy at home or at work, you can choose from many different humidifier and diffuser combos.
A humidifier diffuser combo is a humidifier that has an extra tray to add essential oils. As the mist passes the oil, the scent is released into the air, without the oil coming into contact with the internal components of your machine.
As a result, you can have fresh, fragrant air without any risks.
There are several products with the features of both humidifiers and diffusers. For instance, the Everlasting Comfort Humidifier is an excellent combo for circulating essential oils into your surrounding air.

Humidifier vs. Diffuser – What’s the Difference?
A diffuser breaks up essential oils and releases them into the air, while a humidifier simply adds moisture to the air.
Water-based diffusers commonly use ultrasonic vibration to provide a soothing mist. Underneath the water tank is a small, vibrating disc that pulverizes the oil into particles so small that they may escape via the nozzle with the water vapors.
As well as spreading essential oils, diffusers can also be used to add moisture to the air. Their water tanks, however, are usually too small to be beneficial as a humidifier. I’ve covered this further in this post: Diffuser vs Humidifier.
A more convenient way to enjoy the best of both worlds is to get a specialized model that serves as a humidifier and a diffuser in one.
