Here are 8 Benefits of using an essential oil diffuser in your home/ office

  1. Helps sleep better
  2. If you find it difficult to fall or stay asleep at night, diffusing essential oils can help create a conducive environment to give you peaceful sleep as mist produces a long lasting effect to help you to continue to sleep through the night. Scents such as lavender, ylang ylang, vetiver and valerian are quite good in helping soothe you and give a restful night’s sleep.

  3. Stress reliever
  4. As earlier stated, we live in an increasingly stressful time, and various stressors can make us feel restless and unsettled. An essential oil diffuser works to create a calming effect in your home, especially when used with oils such as bergamot, chamomile, rose and frankincense which relieve anxiety and promote calm.

  5. Ward off illness
  6. Essential oils have powerful antimicrobials that can help kill germs lurking in your home. Once the mist is diffused into the air, you increase the likelihood of killing off germs before they get an opportunity to make you ill. Oils such as Oregano, peppermint and lemon work to boost your immunity and decrease the likelihood of you catching a cold or flu.

  7. Pain Relief
  8. Most people commonly apply essential oils directly onto their skin to help with pain relief, but using a diffuser is much more efficient n extending the pain relief effects of the oils. This is because it allows you to inhale the mist which is then absorbed into your bloodstream and travels around your body faster helping combat and relieve persistent pain e.g. headaches, sore joints and overworked muscles.

  9. Repel Insects
  10. This is yet another great use of essential oils, as the scent they produce will often make your home inhospitable to pesky bugs such as mosquitoes, flies and other household pests.

  11. Humidifies the air
  12. As some diffusers use both water and the essential oil, the air in the home is immediately humidified as a result of the atomization of the water. This is important as dry air is often linked to various respiratory tract issues,a s well as causing dry skin.

  13. Freshen up the air
  14. Essential oils are a great way to freshen u the air in the home without using commercial air fresheners which often contain harmful chemicals that we then end up inhaling. The scents provided by essential oils also tend to be softer and not as harsh as commercial air fresheners. Simply put a scent that you enjoy in your oil diffuser and enjoy.

  15. Safe alternative to candles and incense
  16. Most scented candles have chemicals such as toluene and benzene, which are toxic and can cause damage to our lungs, nervous system and even brains. Because high quality candles without toxic chemicals can be quite costly, a diffuser provides an excellent alternative to scent your home without breaking the bank, not to mention they are also much safer than candles which pose a potential fire hazard when burning.

Let’s now take an in depth look at the various types of diffusers available in the market today, and factors to consider when buying a diffuser.

Types of diffusers

There are four different types of diffusers available in the market today:

Nebulizing Diffusers

A nebulizing diffuser works by blowing an air into a small tube to create a vacuum that will pull the oil from the bottom of the tube to the top to produce a fine spray of the essential oil.

Through the creation of the fine sprays of essential oil from the nebulizer, a large amount of oil can be easily introduced and diffused into the air. Because of this, many have considered the nebulizing type as their choice of essential oil diffuser.

However, nebulizing diffusers tend to use more essential oils to spray in the area than the other types of diffuser. It is recommended to use a timer to set the production of essential oil sprays for only about 15 minutes an hour, which is enough to spread before total evaporation and another round of nebulization.

Humidifying or Ultrasonic diffusers

This kind of diffuser also produces fine sprays of essential oil but in a different way. It has a small disk under the surface a liquid or water that vibrates very fast using electronic frequencies produced by the said type of diffuser.

The vibrations that are produced break the essential oil into microparticles creating a very fine spray. These diffusers do not use heat energy to transform the liquid into vapor like the usual process does. Instead, adiabatic process is used in the the vapor transformation of a liquid, which means no heat is gained or lost in the process.

The fine sprays produced by these diffusers have very small amounts of the essential oil itself and a greater fraction is composed of water. This type is the best choice for those who only want a small amount of essential oil to be dispersed in a room. 

Heat diffusers

These diffusers uses heat to vaporize and diffuse essential oils faster than normal.

Some heat diffusers use high levels of heat energy in order to produce a stronger smell of the essential oil. However the components of the essential oils can be altered because of the use of high levels of heat.

But there are also heat energy diffuser you can choose which only utilizes minimal heat to produce a gentle aroma. Also, because the evaporation process is affected by the density of the liquid, the lighter components of the essential oil may evaporate more easily than the heavier ones.

With this, you are consuming the lighters components during the start of the evaporization and the heavier components later on in the process. This affects the overall therapeutic effect of the essential oil.

Decreased therapeutic effects may be acquired compared to using other types of diffusers. But still, these heat diffusers are affordable and do not produce any sound while on operation. 

Evaporative diffusers

These diffusers operate basically by using air, instead of heat, to easily evaporate the essential oil.

A fan is used to blow air through a filter with an essential oil to hasten the transformation of the essential oil into vapors. The fan is also used to disperse the vaporized essential oil across the room.

Like the heat diffusers which relies on evaporation to disperse the essential oils, the components of the oil are being vaporized in partition based on their density which can affect its effect on your body. Also, these are not very efficient when using thicker essential oils. But still it is a good choice for a relatively quiet essential oil diffuser.

For large areas, it best to use a nebulizer or humidifier/ultrasonic diffuser as they release more concentrated essential oils more efficiently.

Factors to consider before buying an essential oil diffuser for a large room

Motor: When buying a nebulizer or humidifying/ultrasonic diffuser, it is always best to buy a diffuser with a powerful motor that can efficiently spread the essential oil in a large area.

And if you want a silent-operating diffuser, humidifying/ultrasonic diffusers are generally better than the nebulizing diffusers.

Self-Timer: It is always recommended to choose a diffuser with a built-in timer. This way, you shall not waste the essential oil and energy in case you forget to switch it off.

You can set the maximum time of operation to prevent wastage. There are also models with intermittent timers. You can set it to run for hours or for a few minutes within an hour.

Other Factors: You might also want to consider the water capacity of the diffuser for less refilling frequency, especially when you want to cover a large area.

Other models also have an essential oil level indicator and a dispersing regulator to set how much essential oil is being diffused in a specific amount of time.
