There are various diffusers available in the market today and we need to choose one that completely fulfills our preferences. Two most popular diffusers are listed below:

• Ultrasonic Diffusers: These are one of the best oil diffusers available in the market. These diffusers use water along with the oils so that a cool mist of water/oils is released into the air. The best part with ultrasonic diffusers is that they utilize non-heat ultrasonic waves, which do not affect the natural healing properties of essential oils. The ultrasonic frequencies create vibrations in water to vaporize the essential oils. Added features of these diffusers are humidifier functionality (best for winters), auto-shut functionality and color-changing LED lights. Some selected models are also available with remote-control functionality.
• Nebulizing Diffusers: Unlike ultrasonic ones, nebulizing diffusers do not need water to be added to essential oils. They create fine particles with the help of an atomizer and blow them into air. As far as oil diffusion is concerned, these diffusers provide the strongest concentration of essential oils released into air. But these are louder that ultrasonic diffusers and do not have any LEDs fitted. Secondly, because of no water added, these diffusers use oils more quickly, have short run-time and are more expensive as compared to ultrasonic ones.
• Evaporative Diffusers: These are very basic aromatherapy diffusers in which essential oil is applied on a pad or filter and is then evaporated / vaporized through a fan. Inhalers and clay pendants are some of the basic examples of this functionality only. As compared to other diffusers, these are not effective in large rooms or bigger area – but smaller area like your vehicle. However, if you are travelling, these are wonderful for your personal use.
• Heat Diffusers: These diffusers are wonderful to spread the fragrance throughout your home or office. But as far as the therapeutic properties of essential oils are concerned, heat diffusers are not at all effective. In heat diffusers, the essential oils are heated to get diffused. Well, in that process, the user gets lovely aroma but healing properties of the oils are removed with heat.
