What is an ultrasonic diffuser and how does it work?

A diffuser is used to release essential oils into the air. An ultrasonic diffuser uses water and electricity to create vibrations (ultrasonic waves) releasing pure, essential oil molecules quickly into the air through a fine, cooling mist.

The ultrasonic diffuser does not use a direct or open flame like burners, so you can enjoy aromatherapy benefits in the comfort of your home or office. It’s a light, portable device which is simple and easy to use. Simply refill the water, add a few drops of oil and use over and over again.

Are your diffusers BPA-free?

Yes, our diffusers are made from BPA-free plastic. We use only safe and non-toxic materials for our aroma diffusers.

Is it safe to leave the diffuser unattended?

Yes. You can turn it on before you go to sleep and not have to worry about switching it off. Your diffuser will switch off automatically when the water level drops to a certain level.

Will I get the same strong aroma as that from a scented candle or air freshener?

The strength of the aroma will depend on size of your diffuser and room. If you’d like a stronger aroma, use more oil drops or use the diffuser in a smaller room.

Do your diffusers work like humidifiers?

Our diffusers only disperse a light, aromatic mist over a small area. While the functionality is similar to what a humidifier does, it cannot replace it.

How do I care for my diffuser?

Clean your diffuser every few days so that it works efficiently and to remove oil residue. Empty or replace the water in the reservoir daily to avoid mold.

Can I run the diffuser without turning on the light function?

Yes. All our diffusers can be used without the light.


How do I know if an essential oil is 100% pure?

Pure (authentic) essential oils are usually named (scientific or botanical name) after the plant from which it’s extracted.

Also check for how the oil is extracted, distillation process, where the plant is grown. Some expensive oils like jasmine and rose may be combined with carrier oils. A carrier oil is also known as a base oil or vegetable oil. Carrier oils are often used to dilute a pure oil. We recommend using only pure essential oils without dilution in your diffuser to avoid blockage or buildup of oil residue. Acacia offers only 100% pure essential oils. All essential oils undergo gas chromatography test to ensure its quality and purity.

What’s the difference between fragrance oils and pure essential oils?

Most fragrance oils are synthetic chemical scents. They are cheap and used in cosmetics, as food flavours and in perfumes.

Pure essential oils originate from plants and distilled using steam or cold pressing. They do not contain any vegetable oils or synthetic compounds. The oils are 100% natural.

Can I use the oils on my baby or while pregnant?

Some essential oils are not recommended for pregnant or breastfeeding women and are unsuitable for babies. Please check the relevant product information and consult your health professional before use.
