Ultrasonic or Humidifying Diffusers - Ultrasonic vibrations break up oil molecules to create a fine mist. You will need to dilute the essential oil with water in order for the diffuser’s electronic frequencies to release the oil into a mist. Ultrasonic diffusers work like cold humidifiers, which makes them a great choice if you want to add moisture to the air, especially during cold season. The plastic ultrasonic parts require cleaning as oils can be corrosive to plastic.
Evaporative Diffusers - In this type of diffuser, a small fan helps turn oil to gas, making oil evaporate into the air. However, as the oil evaporates, it loses some of its potency. So, this is a good choice for people who want a quick, occasional aromatic sensation.
Heat or Electric Diffusers - Instead of using a fan to turn oil to gas, a heat diffuser uses heat, most commonly, electric. Heating oil may change its chemical properties making the oil less or more intense depending on its properties. Because there’s no fan involved, these guys are totally silent. Different types of heat diffusers include candle diffusers, electric heat diffusers, and lamp ring diffusers.
There are also some tricked out oil diffusers on the market with cool features like ambient lighting and sound features. Design-led ceramic or reed oil diffusers give your space a wellness vibe, whether you opt for a minimalist or hygge aesthetic. Oil diffusers with automatic switch-offs or timers are a good choice if you plan to use your diffuser for extended periods of time, or to fall asleep.
Benefits of Oil Diffusers
Using an oil diffuser can help you breathe easier, and not just because you’re tapping into your zen. “Many essential oils have reputed medicinal or therapeutic uses, like eucalyptus for colds and respiratory issues,” says Benjamin.
Just as you might blend notes in a perfume oil, you can harmonize different essences in your oil diffuser and create a signature blend. Choose notes not only for their scent, but for their healing properties. “When I want to be energized or am working at my desk I would use a blend of bergamot and cardamom,” says Kellet. “This is a great blend for when you need to concentrate. Bergamot is instantly uplifting with a dry citrus note and cardamom is great for focus and mentally clarifying. “It’s like a breath of fresh air.”
If it's relaxation you seek, Kellet recommends a blend of geranium, frankincense, and mandarin. “Geranium is balancing and calming, Frankincense will deepen and slow your breath and mandarin will bring a sweetness to the blend and add a gentle uplifting aroma.”
