How Do Humidifiers, Diffusers and Vaporizers Clean Your Air


A diffuser, often known as an essential oil diffuser, is a device that disperses essential oils into the air. It functions similarly to a humidifier in that it emits moisture into the air. You can, however, add your preferred essential oil to the tank or an oil tray.

When you turn on the gadget, the essential oils combine with the water and are then released into the air. Diffusers are frequently used to create a fragrant environment and can provide several health advantages by raising the humidity.


The primary aim of a humidifier is to raise the humidity in your house. Humidifiers are classified according to their size and purpose. Humidifiers are designed to regulate the relative humidity in your house between 30 and 50 percent.

Simply fill the tank and choose your chosen setting. Most gadgets include a timer that you may set to the hours you want the device to function.


Vaporizers, like humidifiers, are designed to enhance the humidity in your house. They do, however, function differently.

Vaporizers heat the water in the tank needing electrically driven heating elements. As a result, the water boils, producing steam that is distributed through the air.

What They Do to Add Moisture to the Air


A diffuser combines water from a reservoir with essential oil, which is subsequently spread in the air. Essential oil diffusers can assist add humidity to a space, but they aren’t as effective as humidifiers.


Ultrasonic humidifiers are a typical form of humidifier. This humidifier produces a fine mist of moisture into the air by needing ultrasonic vibrations. A cold mist is spread in the form of small, easily breathed particles. Furthermore, because it is cold, it will not create moisture.


Vaporizers, on the other hand, use heat to produce steam or vapor for inhalation. Although it is commonly referred to as a warm-mist humidifier, the moisture that is spread is cooled before reaching you.

What Methods Are Used To Clean Them


It is critical to clean your essential oil diffuser on a regular basis since the oil can accumulate and produce blockages. Depending on how thoroughly you want to clean your essential oil diffuser, you may do it in a variety of methods.

Filling the tank with clean water and adding two squirts of dishwashing detergent is an easy way to get started. Allow the liquid to remain for a minute or two before gently scrubbing the interior with a sponge. You may also add two tablespoons of white vinegar to the clean water and let it for up to ten minutes.


A typical issue with humidifiers is the accumulation of limescale or minerals in the tank and disperser. This is common when you use mineral-rich tap water, commonly known as hard water.

Mould and mildew are other concerns with humidifiers. This is common if you leave water in the tank for an extended length of time.

Taking apart a humidifier and pouring a couple of tablespoons of white vinegar into the tank is the simplest method to clean it. Fill it halfway with water and shake it vigorously. Mould, mildew, limescale, and mineral buildup may all be efficiently removed needing vinegar.


Because vaporizers heat the water, they need to be unplugged and allowed to cool for 30 to 60 minutes before cleaning. Then, if there is any remaining water in the tank, drain it and remove the heating element. Fill the tank with clean water to rinse it, then drain it and wash it down.

Soak the heating element in pure white vinegar for up to 10 minutes before rinsing it under running water to clean it. Make sure your finger is covering the steam outlet. Turn it upside down between rinsings to drain any water that may have accumulated inside the element.

What Do They Cost?


Diffusers generally cost between $13 and $30, depending on size and, in certain cases, design. Some gadgets are more expensive since you also get a few essential oil samples to try.


The cost of a humidifier ranges from $14 to $100. The more costly variants have larger tanks and more functions, whilst the less expensive models are smaller and simpler.


Vaporizers generally cost a little more than $30, although you can easily find versions for around $15.



Diffusers are mostly safe, but there are a few precautions to take, especially if you have children or pets.

Some diffusers can get pretty hot when the water and oils heat up. This can be hazardous if it is within young children’s grasp.

Oils might also pose a threat. Due to the high concentration of essential oils, cats and dogs might be extremely sensitive to them.


Cool-mist humidifiers are suitable for use in the presence of pets and children. They produce no heat and do not distribute potentially toxic essential oils. However, you should keep them out of reach of youngsters to avoid the gadget being toppled over.

However, keep in mind that if you do not properly maintain your humidifier, it may leak pollutants and mold into the air.


The most serious issue with vaporizers is burning. If the gadget falls over, boiling hot water will be spilled, burning your flesh. If you have children or pets in the house, keep the vaporizer out of their reach to avoid burning them.

How Effective They Are in Reducing Congestion


Similar to allergies, the effectiveness of the diffuser is completely dependent on the oils you use. Peppermint and eucalyptus oils are well-known for their ability to clear congestion and expand the airways.


A humidifier is particularly good in relieving congestion because it adds moisture to the air. It’s also a popular gadget for dealing with cold and flu symptoms.


Vaporizers, like humidifiers, provide moisture to the air, which helps to relieve congestion.

Can You Add Essential Oils To A Diffuser, Vaporizer or Humidifier?


The major benefit of a diffuser is that you may add your preferred essential oils to the tank.


Essential oils should never be added to the tank of a humidifier since they might damage the internal components. You may add smells to your humidifier by needing water-soluble scented additives.


Certain vaporizer manufacturers, such as Vicks, allow you to add inhalants such as Vicks’ Soothing Vapors. This, however, should not be used near youngsters.

How Effective They Are for Allergies


When it comes to allergies, certain essential oils might be useful. For example, peppermint, which has anti-inflammatory properties.

However, needing the incorrect oils or mixtures may result in an allergic response. As a result, prior to adding oils, it is critical to conduct some studies.


Low humidity can irritate the airways, while excessive humidity is the major source of indoor allergens.

Dust mites, mold, and Itness can all be caused by high humidity levels. It is also critical to maintain the humidifier clean in order to prevent mold from spreading through the air.


If you have indoor allergies as well as low humidity, a vaporizer is a better alternative. Contaminants are destroyed and eliminated by boiling the water, resulting in a clean mist.

Choosing Between a Diffuser, a Humidifier, and a Vaporizer Bottom Line

If you have dry skin or congestion, adding a little moisture to the air is beneficial. Diffusers, humidifiers, and vaporizers all add moisture to the air effectively. So, how do you make your decision?

Consider what you require. Do you want the aromatherapy of a diffuser or the power of a humidifier?

Regardless of the gadget, cleaning it on a regular basis is critical — and it should be done in accordance with usage. However, it is always a good idea to empty and clean off the gadget after each usage.
