Many people enjoy the benefits of using essential oil diffusers in their home. They take seconds to prepare and give hours of endless, fabulous scent. Using different essential oils, you can create a variety of moods and use certain oils to reduce stress, boost energy, lift mood and even encourage restful sleep.

Diffusers can be used at any time of day and most just need a little water blended with your favorite essential oil to infuse your home with a pleasurable aromatherapy experience.

What is an Ultrasonic Essential Oil Diffuser?

An ultrasonic essential oil diffuser is slightly different from others available. Generally, essential oil diffusers disperse essential oils into the air in the form of vapor. This vapor is easily absorbed into the atmosphere and if you want to, you can even blend essential oil scents together to create something unique or with multiple benefits.

Ultrasonic aromatherapy diffusers create vapor by adding water. The water vibrates until it eventually evaporates. When the water droplets disperse into the air, they carry the essential oil’s fragrance with them. The added bonus of using an ultrasonic essential oil diffuser is that it doesn’t use heat.

Types Of Diffusers

There are other types of diffusers, as follows:

  1. A heat diffuser uses heat that causes the essential oils used to evaporate.
  2. A nebulizing diffuser works using a process that distributes pressured air which breaks down the essential oils. Then, a vacuum pulls the pressured air to the surface, scattering the essential oils into an almost invisible mist.
  3. An evaporative diffuser consists of a fan that generates wind. The wind evaporates the essential oil which is captured in an absorbent material that releases the scent.


The Benefits of Using an Ultrasonic Essential Oil Diffuser

Essential oil diffusers have numerous benefits and are especially effective in combating mild illnesses and anxiety but there are many other reasons why buying an ultrasonic essential oil diffuser is a good idea:

  • It combats minor illnesses, such as the common cold, coughs, headaches and that’s because many essential oils contain anti-microbial particles thought to encourage the immune system. Choose rosemary, sage, grapefruit, tea tree, thyme or lemon for this purpose.
  • It helps you to breathe freely as the release of essential oils is known to reduce congestion, for example, releasing sinuses, alleviating allergies, breathing problems and common colds. The best oils to use in your ultrasonic essential oil diffuser for this purpose are rosemary, lemon, peppermint, and eucalyptus.
  • Diffusers can help reduce inflammation and ease pain relief. So if you’ve had an intense workout or you’ve injured a joint, releasing essential oils can speed up recovery. A diffuser is also recommended relief for tension headaches. Try chamomile, lavender, rosemary, ginger or bergamot essential oil for pain relief.
  • Using one can help you sleep better. Releasing essential oils in the evening soothes and calms, especially if you want to encourage a better night’s sleep. The best oil for this purpose is lavender.
  • The diffuser can also repel insects when used with the right type of essential oil, particularly mosquitos, moths, and house flies. Try blending thyme, basil, lemongrass and eucalyptus oils together to get rid of uninvited house guests!
    It helps to boost cognitive function. Some essential oils are excellent for lifting mood and helping you to concentrate. Soothing and lifting, the best oils for this are lemon, pine, peppermint, and eucalyptus.

A diffuser with a pleasant essential oil helps to create a welcoming atmosphere in your home. Most essential oils deliver a pleasing fragrant experience, so try different scents until you find a few favorites.

The Differentiation

Humidifier VS Diffuser

You might find that some people swear by using a humidifier over a diffuser but they are different products. A humidifier adds humidity to the air, keeping it moist so they’re good if you’ve got a cough or a cold or you have dry skin for example. They operate using a large tank of water.

The water is heated up and releases air and they don’t release a fragrance. Ultrasonic essential oil diffusers work using a very small tank and don’t involve heat at all. It also releases fragrant essential oil particles and can help to clear sinuses. Diffusers have a wealth of other benefits as discussed above.

Diffuser VS Vaporizer

A vaporizer generates water vapor and is particularly effective for medicine. Unlike an ultrasonic essential oil diffuser, it heats water so that it turns into steam and releases the vapor. There is no heat involved in the ultrasonic essential oil diffuser and that’s because when you combine intense heat with essential oils, you usually lose the therapeutic qualities of the oil.

Diffuser VS Air Purifier

Air purifiers are best for allergy sufferers because they remove pollutants from the air such as allergens, dander, dust, smoke, mold, and odors. They make the air cleaner and aren’t for use with essential oils. They don’t have any soothing, calming benefits but they’re excellent if someone suffers from breathing problems or allergic reactions. There’s no fragrance involved.

What to Look for in an Ultrasonic Essential Oil Diffuser

Before you choose the perfect ultrasonic essential oil diffuser for your needs, it’s a good idea to check that it has all the qualities you want. Here’s a list of what you should look for:

  • Check the operating time
  • If you use heat, you should definitely choose a diffuser with auto-shut off for safety
  • Look at the water capacity, the lower the capacity, the shorter the running time
  • Consider what the product is made out of
  • If you want something to help you sleep, check that it’s silent or almost silent
  • If you’re a beginner, it’s probably best to choose something that is very easy to use
  • Check the manufacturer’s guarantee
