Are You Using the Right Aromatherapy Diffuser? Here's a Quick Guide

There are 4 different types of diffuser types: ultrasonic, nebulizing, evaporative, and heat. Find out what makes each one unique and how to utilize them in different spaces.

Ultrasonic Diffusers

Ultrasonic diffusers are great for small to medium sized spaces (bedroom, living room, office, etc.)

These diffusers work by using water and ultrasonic vibrations generated by a small disc at the bottom of the diffuser to dispense a fine mist of water and essential oils into the air. Since ultrasonic diffusers add moisture to the environment (they double as humidifiers!), they are most effective in environments with low humidity. Using ultrasonic diffusers in already humid environments increases the risk of developing mold or mildew. Using a waterless diffuser would be a better fit for moisture-prone spaces (see our waterless nebulizing diffuser!)

We’ve recently innovated on this diffuser type to create an ultra-hydrating beauty diffuser! Powered by a long-lasting, rechargeable battery, this portable diffuser releases a strong, finely atomized mist of oil and water into the air, designed to moisturize your skin. It also features one of the longest working times on the market, the first ever beauty diffuser to work continuously for 25 minutes!

Nebulizing Diffusers

If you’re looking for a powerful diffuser with extensive coverage, the nebulizing diffuser is the way to go. They are also a great choice for more humid environments since they don’t dispense water into the air.

These diffusers use pressurized air and a nebulizer that breaks down essential oils into ultra-fine particles to distribute aromatherapy into the environment. Since the oils are in a more vaporized, gaseous state, the aroma is more evenly distributed throughout your space.

Since nebulizing diffusers don’t require water or heat, you are able to get the maximum undiluted, unaltered benefits from your oils with this method.

Evaporative Diffusers

As the name suggests, these diffusers rely on the process of evaporation to diffuse aromas into the air and don’t require batteries or heat. Usually in the form of a porous material or scent sticks, these diffusers are great for smaller areas like bathrooms, small rooms, or anywhere where you want a natural, continuous scent disseminated into the air.

One of our most-loved products is our car diffuser! Simply add your desired essential oils to the scent stick and clip it into your air vent to release the aroma into the air.

Heat Diffusers

Usually using a candle or a light bulb, these diffusers utilize heat to promote the evaporation of aromatherapy into the air. This method is best for small to medium spaces.

Heat diffusers are efficient and economical but heat can alter the chemical composition, and thus the therapeutic benefits of essential oils.
