Read through the below sections to understand the features, functionality and benefits of choosing an essential oil diffuser that is right for you and your situation.
Benefits of Diffusing Essential Oils
Diffusers need not just be something you see in spas! The practice of spreading beneficial fragrance has been practiced for centuries and you can bring this to any space around you, be it your home, office, bathroom and even your car. Here are some benefits that diffuser can bring you:
- Masks odors: Spaces that smell musty or dank can easily be refreshed with fragrant essential oils like lemon, tea tree, orange and more quickly. These natural options are better for your health and the environment than other chemical sprays.
- Induce feelings of calm and positivity: Just as tea and tonics can soothe you and help you reduce stress, essential oils when inhaled can have the same effect. Oils like lavender, eucalyptus or chamomile can have this effect.
- To minimize the effects of seasonal threats: Essential oils with anti-microbial properties can boost the fighting powers of your immune system. This can be particularly comforting if you suffer from seasonal cold or the flu.

Types of Essential Oil Diffusers
There are 4 major kinds of diffusers available in the market including:
- Nebulizer Diffusers
- Ultrasonic Diffusers
- Evaporative Diffusers
- Heat Diffusers
1) Nebulizing Diffuser
Perfect for those who use essential oils regularly, practice aromatherapy and require fragrance over large spaces.
The best kind of diffuser in our opinion is the nebulizer as it does not use heat, plastic or water to give off a fine mist of fragrance. It works by a combination of pressurized air and oil- air is forced through a small tube that creates a strong enough vacuum to pull oil to the surface in the form of mist. Because there is no heat involved, the essential oils retain their integrity and natural properties.
2) Ultrasonic Diffuser
Perfect for those who use essential oils to mask odors and smells or to create a spa-like atmosphere.
This kind of diffuser is also called as a humidifier and a vaporizer as it requires water instead of air. In a process similar to the nebulizer, ultrasonic diffusers use electronic frequencies to create vibrations in the water to break up oil molecules for distribution. They can not only produce a nice fragrance but also add humidity to the area where it is used.
3) Evaporative Diffuser
Perfect for those who are on a budget and require diffusion in small areas.
Evaporative diffusers are modern form of the traditional method of essential oil diffusion. Oil is placed on a filter or any other surface and a fan is blown on it. The moving air causes the oils to evaporate quicker than they would and spreads the scent into space.
4) Heat Diffuser
Perfect for complete beginners who are on a budget.
The oldest and most traditional type of diffuser, this type uses heat to atomize and release the fragrance from the oils. Heat warms up the essential oil, causing it to it evaporate into the air. Because it is very basic, this kind of diffuser is the cheapest. affordable from among the options. diffuser, the essential oils are diffused faster. To get the scent to spread quickly, a high flame can be used however that defeats the purpose as many medicinal benefits can be lost. If you’re a beginner and are looking for an inexpensive or a noiseless, heat diffusers can be a way to start.
Our Final Thoughts & Recommendations
We have discussed each diffusing method with their advantages and disadvantage and on that basis, we would recommend a nebulizing diffuser or an ultrasonic one. Nebulizers are pricier than the rest but they have better diffusing powers and are easier to maintain. Ultrasonic ones are great options as they are more affordable than nebulizers. When choosing your ultrasonic diffuser there are some aspects to consider.
If you plan to use the diffuser as a sleep aid, you may want to avoid the ones that make noise or have bright lights. If run-time is important to you, bear in mind that the range greatly varies across brands as some run for 3 hours and others 12 hours.
Ultimately the decision is yours and you may need to think of other considerations such as the space available to you, which design you like and if you have pets or kids who are prone to knock things down.
