Essential oil diffusers

Essential oil diffusers do exactly this - diffuse essential oils throughout your home. There are a few different kinds of essential oil diffusers.


For example, the Scent Australia Micro Diffuser.

Nebulizers neither use water or heat. They diffuse the essential oils in their purest form.


  • One touch – powerful scent on demand!
  • Undiluted, the oil gets to the body and the environment in its purest and most potent form
  • Lacking heating, the oil remains unaltered and intact (heating oils could cause toxic mutation!)
  • Comes with a timer so you can regulate its use more strictly
  • Output setting is adjustable to achieve the desired scent level
  • No lights (won’t disturb your sleep in the night)
  • Easy to use, no setup required
  • It is the best for therapeutic use
  • No messy mixing with water required
  • Scent Australia Micro diffuser (nebuliser) is easy to use and available with rechargeable inbuilt battery or mains powered option


  • The only downside of this diffuser is that the micro onboard air pump emits a sound, which is noticeable in very quiet rooms

Ultrasonic diffusers

Unlike nebulizers, ultrasonic use water to aid diffusion. And as the name suggests, they are completely noiseless. These usually emit a mist that carries the scent of the oil.


  • Can be cheaper than nebulisers
  • Silent
  • As the oil is diluted, it lasts longer - however, this comes at the expense of effectiveness


  • They need setting up in order to work effectively
  • The dilution with water means they are less potent
  • Frequent refilling is required
  • Humidifying the air might be undesirable
  • Messy mixing with water can create a mess

Personal diffusers

Also called evaporative diffusers, these diffusers are significantly smaller than the normal essential oil diffusers. The diffusion is made possible by air circulation either naturally or artificially by small fans.


  • Affordable
  • Noiseless
  • They can worn as necklaces, bracelets, and earrings.
  • Portable
  • Personal


  • Small and not effective as room-wide scent diffusers

Reed diffusers

Reed diffusers are usually glass bottles containing scented oils, with reed sticks protruding from the top. The oil flows up the sticks before diffusing into the surroundings. They are often used in high traffic areas or in desolate rooms and houses.


  • Relatively inexpensive
  • Diffuse silently
  • Aesthetic (look great as decor!)
  • Very long lasting


  • Much less effective than nebulisers
  • Diluted with carrier oils, meaning they aren’t as pure
  • Limited to one permanent scent per diffuser (can’t change frequently)
