The most common use in the practice of essential oils is aromatherapy/essential oil therapy with the help of a diffuser. Diffusing essential oils into the air and breathing in essential oils might allow them to enter the lungs and bloodstream, where some helpful compounds may benefit the human body.

Essential oils can be applied to the human body’s skin but never apply that without diluting them with the help of carrier oils. My suggestion is to do an allergy test before applying them to your skin if you have sensitive body skin.

To do an allergy test

  • Dilute essential oil in a carrier oil at twice the concentration you plan to use.
  • Rub the mixture into an area the size of a quarter on the inside of forearm.

If there is no allergic response within 24-48 hours, it should be safe to use.

Difference between oil diffuser and humidifier.

Using essential oils in a diffuser or a humidifier is compulsory to have a look at the differences between humidifier and diffuser.

They both add moisture to the air but they are different from each other.

What is an oil diffuser?


Essential oils diffuser or aromatherapy diffuser is a device that breaks essential oils down into smaller molecules and dispersing them into the air for a pleasant and calming effect depending on oils used in the diffuser.

Types of diffusers.

You can find four types of an oil diffusers in the market nowadays.

  • Evaporative diffusers: one of the best choices for people who want a quick, occasional aromatic sensation. These types of diffusers have a small fan that helps turn oils into gas, making oil evaporate into the air.
  • Nebulizing diffusers: Nebulizing diffusers do not require water and heat, which makes them a low maintenance choice. The purpose of nebulizing diffusers is to use pressurized air to diffuse a mist of oil. A vacuum pulls oils to the surface of a distribution tube which results in a burst of aroma into the air.
  • Heat or electric diffusers: Heat diffuser uses heat and heating oil may change its chemical properties making the oil less or more intense. Heat or electric diffusers are silent because of no use of a fan as these diffusers do not have a fan.
  • Ultrasonic diffusers: these diffusers have the ability of ultrasonic vibration which breaks up oil molecules to create a fine mist. Ultrasonic diffusers are a great choice if you want moisture in the air, especially in the cold season. Rember we have to dilute the essential oils with water for the diffuser’s electronic frequencies to release the oil into the mist.  These diffusers are just the same cold humidifiers.

What is Humidifier?


A humidifier is a device, unlike a diffuser is not designed to handle essential oils, a common purpose of a humidifier is to add moisture to the air which helps to prevent dryness that can cause many problems in the human body. A humidifier is helpful to ease the symptoms of the common cold or flu. A humidifier is effective to reveal

  • dry skin
  • nose irritation
  • cracked lips
  • dry throat
  • dry skin
  • bloody nose
  • sinus congestion
  •  headache.

Note: Overusing humidifiers may affect the respiratory system.

Types of humidifiers.

let’s have a look at the following types of humidifiers.

  • Cool mist humidifiers: cool mist humidifiers work better in warmer seasons, the cool mist gives ease of breath but cool mist units can be a little bit noisy than their warm mist counterparts. Cool mist humidifiers have a filter that traps minerals and then a cool invisible mist evaporates into the air. Cool mist humidifiers have more maintenance with filters.
  • Warmer mist humidifiers: a better option that the mist is produced tends to be cleaner than cool mist humidifiers. These are great for treating cold and flu. A warm mist humidifier requires frequent cleaning and generally more difficult to clean also covers a smaller area than their cool mist counterparts.
  • Central humidifiers: Best choice but most expensive, these humidifiers are built directly in your air conditioning or heating unit, that’s why they are the best choice if you want humidity through your entire premises.
  • Ultrasonic humidifiers: Ultrasonic humidifiers have a metal diaphragm and create water droplets that are then put into the air via a fan. these units are particularly silent and create a cool fog.
  • Impeller humidifier: Impeller humidifiers have a rotating disc that runs at a high speed. Impeller humidifiers are less expensive and child-friendly because they create cool mist and carry no risk of burns. These humidifiers must not be overused as they may cause breathing difficulties for those with allergies and asthma.
  • Evaporators: More affordable humidifiers having moistened filter that blows moisture and expels the humidity into the air from a single unit system. These humidifiers can work in a single room at a time and expel too much moisture into the air that can be problematic to people with asthma.

The bottom line

Essential oils can be used by diffusers and that may damage humidifiers. Diffusers are designed for essential oils and will ensure you will reap the benefits of the oils.
