A buying guide to the top essential oil diffusers

These products are available in various designs, colors, shapes and styles, and each offers different features. Our buying guide will help you find the right one for your home or office.

What to keep in mind when buying an essential oil diffuser

When buying these kinds of products, you need to consider several important factors. Some of these factors are mentioned below:

diffuser type

There are different types of diffusers available, including nebulizers, humidifiers and ultrasonic diffusers. Each type of diffuser has a different function and provides different benefits. For instance, if you are on a budget and have a smaller space, an evaporator is an ideal product.

Choosing a candle diffuser allows you to add a warm ambiance to your room, but the most critical benefits are offered with a nebulizing diffuser. So, choose an essential oil diffuser that fulfills your requirements and suits your particular needs.


While the design of an essential oil diffuser is not a primary concern, it is considered important when buying these products. The design may be critical to those highly invested in every item in their space representing a style statement.

So, you may want your diffuser’s design, color and finish to complement your established interior design. Moreover, if you like traveling with your diffuser, you may want to opt for a lightweight and compact design.


To get the maximum benefits from a product, you need to utilize its functions fully. For that purpose, the item has to be maneuverable. If a product requires a difficult setup, it may cause frustration. So, make sure you consider ease of use and assembly when making a purchase.

Safety features

A good product shouldn’t lack essential safety features like an auto-off mode and timers. These features are essential because many people use diffusers as sleep aids. If the diffuser runs out of water but doesn’t switch off, it can lead to malfunction. Similarly, these kinds of products can become overheated if not shut off in time, becoming a fire hazard.

Types of diffusers

You can find these products in different styles. Below, we have mentioned some of the most popular types of diffusers:

Ultrasonic diffusers

An ultrasonic diffuser uses electronic frequencies, creating vibrations and dispersing a fine mist of essential oils or water. Most people prefer these diffusers because they do not use heat to diffuse the oils, preserving a greater share of their benefits. Since they use water and essential oils, ultrasonic diffusers can also serve as humidifiers. These products are relatively inexpensive, quiet and durable.

Heat diffusers

This type of product uses heat for diffusing essential oils and dispersing them into the air. Such diffusers include candle burners, lamp rings, steam inhalers and electric heat diffusers. These are also inexpensive and noise-free, but since they use heat, they can alter the potency of oils.

Nebulizing diffusers

Nebulizing diffusers or nebulizers are somewhat similar to perfume atomizers, delivering powerful and aromatic bursts into the air. These products use an atomizer for breaking down essential oils into tiny molecules, then spreading them around in the form of droplets. Nebulizers do not dilute essential oils with water or heat, so their burst is relatively stronger. Generally, nebulizers are more expensive and tend to be on the noisier side.

Evaporative diffusers

Evaporative diffusers use a fan for transforming essential oils into gas and evenly dispersing around a room. These products have a pad or filter under the fan for dropping oils. This type of item is inexpensive compared to other models. However, the mist released from these diffusers is less concentrated and usually unbalanced. Due to this, these products are more suitable for smaller spaces, like office cubicles.

Benefits of essential oil diffusers

Using these products is beneficial in various ways. Some benefits are mentioned below:

Promoting calmness and relaxation

The primary benefit of aromatherapy is inducing relaxation by promoting a serene environment. Essential oils have therapeutic properties helping with relaxing and unwinding after a long, hard day. You can combine aromatherapy with other activities maximizing its self-soothing benefits. For example, you can diffuse your favorite oils while running a hot bath, doing yoga or meditating.

Improving clarity and focus

Besides the relaxing properties of essential oils, you can also use them for improving focus. Some people love diffusing their favorite oils at work, letting the energizing fragrances enhance concentration and improve their focus.

Encouraging better sleep

Many people use these products as sleep aids. These items are ideal for you if you have trouble falling or staying asleep. Make sure to choose a calming, soothing scent before going to bed. These fragrances can help relax your nerves, enabling you to sleep peacefully through the night.

Safety tips

To get the maximum benefits from your product, you should follow all safety guidelines. These include but are not limited to the following:

  • Make sure you purchase high-quality essential oils from reputable stores and sellers

  • Carefully read and follow the instruction manual that comes with your product

  • Always put the correct amount of essential oils in the diffuser

  • Stop using a particular oil if you notice any allergic or asthmatic reactions

  • Make sure essential oils do not come in contact with flames

  • Do not use diffusers continuously for extended periods

  • Make sure to use child and pet-friendly diffusers and scents

  • Clean your essential oil diffuser regularly to improve its lifespan

Which is better, a humidifier or essential oil diffuser?

Humidifiers and diffusers are both great options, depending on your preferences and needs. For instance, if you have dry air in your home, a humidifier is ideal.

Can you use an essential oil diffuser with just water?

You can use essential oil diffusers with just water if you want to improve the room’s humidity level with adding fragrance. However, it will not function as well as a humidifier.
