Can You Put Essential Oils in a Humidifier?

Understanding and Maintaining Your Humidifier for Optimal Health and Comfort
Humidifiers have become indispensable appliances in homes and offices, especially during the dry winter months or in arid climates. They are essential for adding moisture to the air, which can help alleviate health issues such as dry skin, sinus congestion, and respiratory discomfort. But as the popularity of aromatherapy grows, many people are asking: “Can you put essential oils in a humidifier?” This comprehensive guide explores the compatibility and safety of using essential oils in humidifiers, explains how humidifiers work, and provides detailed instructions on how to clean a humidifier properly.

Can You Put Essential Oils in a Humidifier?

The short answer is: it depends. Not all humidifiers are designed to distribute essential oils. In fact, adding essential oils to a humidifier that isn’t built for them can damage the device, impair its function, and potentially release harmful chemicals into the air. However, some humidifiers are designed to double as diffusers, specifically made to handle essential oils. These are typically ultrasonic humidifiers, which create a fine mist using ultrasonic vibrations. If you want to add essential oils to your environment, it’s essential to invest in a humidifier with an aromatherapy tray or one explicitly labeled as an essential oil diffuser.

Understanding how humidifiers work is crucial to maintaining your device and ensuring you use it safely with or without essential oils. The primary purpose of a humidifier is to release water vapor or steam into the air to increase humidity levels. There are several types of humidifiers:
1. Central Humidifiers: Built directly into a home’s heating and air conditioning system, these are the most thorough way to humidify your entire dwelling.
2. Evaporators: These use a fan to blow air through a moistened filter or belt.
3. Impeller Humidifiers: A rotating disk flings water at a diffuser, which breaks the water into fine droplets that are released into the air.
4. Steam Vaporizers: These electrically powered humidifiers heat water and then cool it before expelling it into the air.
5. Ultrasonic Humidifiers: These use ultrasonic vibrations to produce a cool or warm mist.
Each type has its unique mechanism and ideal use case, but ultrasonic and impeller humidifiers are generally safer as they do not involve hot water and reduce the risk of burns.

Essential Oils in Ultrasonic Humidifiers

When it comes to adding essential oils to a humidifier, ultrasonic models are usually the best option. These types of humidifiers create vibrations that turn water into a fine mist. If essential oils are added, these oils become part of the mist and are dispersed along with it. Still, ensure the manufacturer’s instructions permit the use of essential oils in the device.

Benefits and Risks of Essential Oils in Humidifiers
The benefits of using essential oils in humidifiers can include:
– Enhanced relaxation and mood improvement
– Potential health benefits, such as congestion relief and improved sleep
– A pleasant and natural fragrance throughout your home or office
However, there are risks if not used correctly:
– Oils can damage the humidifier’s internal components, leading to leaks or malfunctions.
– Some essential oils can irritate the respiratory system, particularly in children, pets, or those with asthma.
– Oils may degrade plastic parts or leave behind residues that are difficult to clean.

It’s important to keep your humidifier clean to ensure it is safe to use and operating efficiently. Here’s how you can clean a humidifier:

Regular Maintenance

1. Unplug the Humidifier: Before you start cleaning your humidifier, make sure it is unplugged and cool to the touch.
2. Empty and Rinse the Tank: Pour out any leftover water from the tank. Rinse the tank with clean water to wash out any residual grime.
3. Disassemble the Unit: Take apart the humidifier as much as the manufacturer’s instructions allow. Remove the water tank, filter (if applicable), and any other removable parts.
4. Wipe Down: Use a clean cloth or sponge dampened with water, or a mixture of water and white vinegar, to wipe down the inside surfaces of the tank. Avoid using harsh chemicals or abrasive cleaners as they can damage the unit or leave harmful residues.
5. Clean Mineral Build-up: If there is mineral build-up (often white, crusty residue), you can fill the tank with a mixture of white vinegar and water (usually a 1:1 ratio) and let it sit for about 30 minutes to an hour. Then scrub the interior gently with a brush with soft bristles to remove the deposits.

Deep Cleaning

1. Disinfect with Vinegar or Bleach: After you’ve removed mineral build-up, you can further disinfect the tank by filling it with a solution of 1 teaspoon of bleach per gallon of water or a 3% hydrogen peroxide solution. Let the solution sit in the tank for about 30 minutes.
2. Clean Small Parts: For other parts of the humidifier, such as the cap or the nozzle, you can clean them with vinegar or the bleach solution using a small brush or cloth.
3. Rinse Thoroughly: After using any cleaning solution, make sure to rinse all the parts of the humidifier multiple times with clean water to ensure no chemicals remain.
4. Dry Completely: Let all parts air dry completely before reassembling the humidifier. Moist environments can promote the growth of mold and bacteria.

Replacing Filters

– If your humidifier uses filters, wicks, or cartridges, these should be replaced regularly according to the manufacturer’s recommendations. Cleaning them might not be sufficient as they can become clogged with minerals or degrade over time.


Always consult your specific humidifier’s manual for manufacturer-recommended cleaning procedures and maintenance, as not all humidifiers are cleaned in the same way. Certain parts might require special care or products. If the device has electronics or a motor that should not come into contact with water, be extra cautious when cleaning around these areas.
Cleaning your humidifier should be part of your regular routine, especially during periods of frequent use, and a deep clean is recommended every 1-2 weeks depending on usage and water hardness.
