What are Nebulizing and Ultrasonic diffusers for?

Nebulizing and Ultrasonic diffusers are basically electrically powered devices that help disperse essential oils and negative ions in the air. They do this by triggering a series of reactions that cause the molecules of essential oils to break down into micro molecules, which they then diffuse into the air in the form of negative ions. These negative ions come in contact with the harmful positive ions in the air in your home, get attached to them, and in turn purify your home.

The Science Behind

Ultrasonic diffusers are fed with essential oil and water. The essential oils, being oils, float on the surface of the water, and when hooked on to a source of electricity, the diffuser uses ultrasonic vibrations to agitate the water, which causes a separation of the ions of the water and then leads to expulsion of the negative ions, along with the essential oils.

Nebulizing diffusers differ from Ultrasonic diffusers in that they do not use water, but instead use a pressurized high speed air stream. Nebulizing or Atomizing diffusers are considered to be the best as they have the most therapeutic benefits.

Once the negative ions are released into the air, they bind with the positively charged free radicals, and at the same time, also freshen the air naturally by carrying with them some moisture and essential oils traces.

Reasons to use a nebulizing or an ultrasonic diffuser

As opposed to other alternatives, nebulizing and ultrasonic diffusers do not make use of any heat on the essential oils, which preserves their therapeutic benefits. In addition, they are relatively easy to clean and handle, and create a healthier environment in the home with minimal effort.

How do diffusers work?

All essential oil diffusers, including nebulizing and ultrasonic diffusers, work by a simple process of breaking down the essential oils into smaller molecules and then expelling them out in the air. These oils, when break down into smaller molecules, help improve the quality of air, add freshness to it, and offer health benefits as well.

Depending upon the density and amount of essential oil used, the molecules can stay in the air for as long as a few hours.

What are the different types of diffusers?

Nebulizing or atomizing diffusers are generally more expensive than ultrasonic and heat diffusers. These cold air diffusers work by using room-temperature air to blow the oil into a nebulizer where it is vaporized. They can be a bit tricky to clean.

Ultrasonic diffusers are among the most popular ones and make use of electronic frequencies to generate and disperse the negative ions. These diffusers are easier to clean and do not use as much oil as an nebulizer, generally they are cheaper than nebulizers as well.

Heat diffusers, as the name suggests, make use of heat to disperse the essential oils and negative ions into the air, while evaporative diffusers make use of a fan to blow the air through a pad or a filter which vaporizes the oil on the pad. This type of diffuser is the least effective for health benefits.

Why are electronic diffusers the best?

Ultrasonic diffusers are the obvious better choice over other essential oil diffusers out there, and for many reasons.

  • They are super easy to use.
  • They are easier to clean and manage.
  • They disperse negative ions and essential oils better and cover a larger area of your home.
  • The air saturation percentage associated with ultrasonic diffusers is high.
  • They have low noise level associated with their use.
  • They break down any kind of essential oil effectively, regardless of its viscosity.
  • They have high oil capacity.

If you need the more therapeutic benefits of a nebulizing diffuser, then a more expensive model will be required as cheaper products can be noisy.

If you’ve never used a nebulizing or an ultrasonic diffuser before, you may be confused how to get it to work in the right way. To help you out with just that, here’s are some quick and actionable tips to get started on.

  • First time users can start by diffusing for 15-20 minutes a day and then scale it up and increase the frequency later by diffusing the oils for 15 minutes every hour.
  • Fill up the diffuser tank with distilled or filtered water and add 2-3 drops of any essential oil for a small room, or 6-9 drops for a bigger room to it, and then place the cover back.
  • Plug this into a power source and press and hold the diffusing power button for 2 seconds or as directed by your diffuser.
  • You can add any type of essential oil to your diffuser and reap its benefits.
