One of the best ways to enhance and personalize a space is to Make it smell good with a scent diffuser. A pleasant aroma can transform a plain office, room, or car into an attractive and inviting space for both the owner and guests. Often, people don’t even realize that their feelings about a place are a direct result of what they smell. The best way to add scent to an area is with a diffuser, a device that disperses the scent of an essential oil or oil blend throughout a room through evaporation. There are several different types of diffusers.

Reed Diffusers

The simplest type of diffuser is a hollow reed that is partially immersed in a scented liquid, usually an essential oil mixed with an unscented base liquid. The liquid is naturally drawn into the tiny opening until it reaches the top of the reed, where it evaporates into the air. Reeds use no heat or electricity, so they are safe and easy to use. The only maintenance they require is the occasional addition of more liquid.


A nebulizer relies on a similar principle, that is, drawing a scented liquid into a tube, but it adds blowing air to more forcefully disperse the scent into the room. As air blows across the top of the tube, the molecules of scent are sprayed into the room in a fine mist that quickly fills the room with scent. Because they work quickly and efficiently, they can be used for just fifteen minutes or so at a time.

Heat And Evaporative Diffusers

Both of these types of diffusers increase the speed of evaporation. A heat diffuser uses a low level of heat to speed up the evaporation process, while an evaporative diffuser blows air through a scent-infused pad. Both types of diffusers transfer scent into the air fairly quickly.

Ultrasonic Diffusers

This type of diffuser uses a very small amount of oil in a much larger quantity of water. Electric currents create ultrasonic vibrations that break down the oil and water into a vapor of tiny particles that are easily absorbed into the nose and lungs. Ultrasonic diffusers are often preferred for aromatherapy for this reason.
