An aromatherapy fan diffuser uses a fan to blow essential oils into the air. The essential oils are usually placed on a tray or pad within the unit and then plugged in to a power supply to allow the fan to blow the scent into the air.
Advantages: Aromatherapy fan diffusers allow the essential oil fragrance to be released quickly into the air. Depending on the brand and model, fan diffusers can scent a large or small area and are easy to use.
Fan diffusers can be powered using electricity or batteries (again, depending on the brand) which makes them portable and convenient.
Disadvantages: In addition to purchasing the essential oil, some aromatherapy fan diffusers require the purchase of replacement pads to absorb the oil. Also, some fan diffusers can be pretty noisy.
Electric Aromatherapy Diffusers
Electric aromatherapy diffusers use electrical heat to gently warm the oil to release the aroma into a room. Some use a fan and some do not.
Advantages: Electric diffusers can more efficiently disperse the aromas of thicker oils such as Ylang Ylang and Sandalwood.
Disadvantages: You must have a power supply available to use an electric diffuser. The electric heat may alter certain elements of the essential oils making their therapeutic benefits less optimal.
An aromatherapy candle diffuser, uses a ceramic or metal bowl to hold the essential oil while a tea light or some other type of candle is used to gently heat the aromatherapy oil. The heat causes the oil to slowly evaporate into the air.
Advantages: Candle diffusers are decorative and can be inexpensive, depending on the design. Candle diffusers don’t require electricity or batteries.
Disadvantages: Although very inexpensive tealight candles are small and will need to be replaced frequently. The release of aroma from a candle diffuser is usually pretty light and takes a while to permeate a small room.
A nebulizing aromatherapy oil diffuser is a device that breaks down essential oils into smaller molecules before dispersing them into the air. These smaller molecules are more easily absorbed by the lungs creating a greater therapeutic benefit than the other diffusion methods. A nebulizer diffuser is made up of a base (usually plastic) that contains the motor, and a glass piece that holds the oils.
Advantages: Aromatherapy nebulizers break down essential oils into smaller molecules which makes it a better diffuser choice if you want the best therapeutic benefit from an aromatherapy diffuser.
Disadvantages: Cleaning the nebulizer diffuser is time consuming. The glass is breakable and expensive to replace. Thicker essential oils can clog some nebulizers depending on the style.
Reed diffusers are becoming more popular because they are asthetically pleasing. In reed diffusion, essential oil is poured into a bottle; reeds, which look like little sticks, are then inserted into the top of the bottle. The reeds then become moist, absorbing the essential oils and emitting scent throughout your room. Occasionally turning the reeds refreshes the scent.
Advantages: Reed diffusers can be inexpensive. Reed diffusers last a long time and can release scent into a room for up to a month.
Disadvantages: The release of aroma from a reed diffuser is very light and will usually only scent the immediate area where it is located.
Steam Aromatherapy Diffuser / Vaporizer
The steam method quickly diffuses oil into a room. The steam will heat the oil and cause it to evaporate quickly into the room. The vaporizer diffuser uses a cool mist process that breaks down water and oil into airborne molecules without heat.
