Can I Use a Humidifier with a Diffuser?
Using a humidifier and essential oil diffuser together is a common question for people looking to increase moisture in the air while also enjoying aromatherapy benefits. The short answer is yes, you can safely use a humidifier and diffuser in the same space as long as you follow some basic guidelines.
In this comprehensive guide, we’ll cover everything you need to know about running a humidifier and diffuser together. You’ll learn how each appliance works on its own, tips for best practices when using both, and the top models suitable for dual use.
How Do Humidifiers and Diffusers Work?
First, it’s key to understand the different technologies behind humidifiers and diffusers:
Humidifiers work by taking regular water and dispersing it into the air in fine droplets or as vapor. This increases moisture levels, helping to relieve dry air problems like:
- Irritated, stuffy sinuses
- Itchy skin
- Static electricity
- Cracked lips
- Scratchy throat
There are two main types of humidifiers:
- Warm mist – These heat the water to create steam. The warm moisture may provide extra relief.
- Cool mist – These use ultrasonic vibration or fans to turn the water into a fine mist. No heat involved.
Diffusers work by dispersing essential oils into the air. The tiny oil particles evaporate, filling the room with the natural aroma of the oil. Benefits may include:
- Stress relief
- Helping sleep
- Uplifted mood
- Clearer breathing
Most diffusers today use ultrasonic technology. This vibrates the water and oil mixture to create a fine, cool mist.
Is It Safe to Use a Humidifier and Diffuser Together?
The key factor in whether you can use a humidifier and diffuser together safely is the type of humidifier.
Ultrasonic and evaporative humidifiers that produce cool mist are generally safe to use along with an ultrasonic diffuser. The cool operation won’t degrade the essential oils.
However, you should avoid using diffusers with warm mist or steam vaporizer humidifiers. The heat can break down or evaporate the beneficial compounds in essential oils before they disperse into the air.
Tips for Safely Using a Humidifier and Diffuser Together
Follow these best practices when running a humidifier and essential oil diffuser in the same space:
Allow Proper Airflow Between Devices
Place the humidifier and diffuser 3-6 feet away from each other. This allows the fragrance to circulate properly throughout the room.
Use Oils Sparingly in the Diffuser
Only use 8-10 drops of essential oil per diffuser use. Too much oil can be overpowering when combined with the humidifying mist.
Clean Both Devices Regularly
To prevent bacteria or mold growth, clean each appliance thoroughly per the manufacturer’s directions. This is especially important if using the same device for both humidifying and diffusing.
Use 100% Pure Oils
Ensure you use only therapeutic grade, 100% pure essential oils. Diluted or synthetic oils may not diffuse properly and can leave residue.
Monitor Humidity Levels
Use a hygrometer to keep an eye on humidity and adjust your humidifier and diffuser usage accordingly. The ideal indoor humidity range is 30-50%.
Shut Off Diffuser at Night
For safety and air quality, shut off the diffuser at night. But you can often leave a cool mist humidifier on 24/7 for continued sinus and skin relief.
What About Using One Device for Both Diffusing and Humidifying?
Some ultrasonic diffuser models also offer a humidification function, allowing you to use one appliance for both jobs. This can be convenient for saving space and money.
However, there are downsides to using a 2-in-1 model:
- You’ll need to clean it more often to remove oil residue
- The tank may hold less water than a dedicated humidifier
- It can only perform one function at a time
If you do choose a dual diffuser/humidifier, look for one specifically designed and marketed for both uses.
