There are a variety of essential oil diffusers on the market, and while they may look different, they're all designed to spread a therapeutic aroma throughout the room. Dispersing the oils in the form of breathable mist, diffusers are a safe and popular alternative to synthetic air fresheners and scented candles.
The most common type of essential oil diffuser is an ultrasonic diffuser. This method uses ultrasonic vibrations to break down the mixture of water and essential oils to produce a cool, fine mist that simultaneously humidifies the air.
As the most powerful, fast-acting mode of defusing, a nebulizing essential oil diffuser uses pressurized air to emit a fine mist—which translates into releasing the oils in their purest form.
This method is often utilized for therapeutic benefits due to its potency. On the other hand, nebulizing diffusers do come with a bit more noise, often producing a humming sound.
Evaporative essential oil diffusers disperse fragrant oil through evaporation. This type of diffuser comes in two styles, both with and without a fan.
The traditional evaporative diffuser contains a pad or filter to house the essential oils and an internal fan to circulate the oil particles throughout the room. The simplified version comes without a fan and relies on natural airflow to disperse the fragrance. Evaporative diffusers are generally budget-friendly and are ideal for smaller spaces.
As the name suggests, a heat essential oil diffuser heats the oil until the particles evaporate and disperse into the air.
The most effective heat diffusers use low levels of heat to slowly and evenly evaporate the oil molecules into the air. The heating source may come in many forms including electricity, a candle, or a lamp ring (similar to a ring light). Each style uses a tray to hold the oil near the heat source. The downside to this method is that heat can change the chemical properties of the essential oil and in some cases, limit the benefits.
