Dangers of Essential Oil Diffusers

Whether in the home, exercise studio, or the office – diffusers are becoming more and more popular due to their ability to freshen up a variety of spaces with a delightful aroma, while also helping to elevate energy levels and moods. But, how do you use a diffuser safely? 

If you’re currently wanting to use a diffuser but are on the fence because you’re unsure of the correct way to use it  – then you’re in the right place!

Below, we’re going to be talking you through all of the relevant safety precautions you should take when using a diffuser, as well as additional advice about using essential oils in general, too. Read on!

How To Safely Use Essential Oils – General Information:

Due to the potency of essential oils, using them will come with a variety of potential risks that you should be aware of.

As a general rule of thumb, essentials oils should never be ingested, and you should never opt to use essentials oils if:

  • You are pregnant or breastfeeding
  • You are under 12 years of age
  • You have a respiratory health condition 
  • You have pets
  • You are over the age of 75 

In addition to all of this, prior to using essential oils, you should also make sure that you consult with your doctor, especially if you have any pre-existing health conditions or are currently taking medication, and are concerned whether or not essential oils may have an adverse effect on you.

It’s always better to be safe than sorry! 

How To Safely Use Essential Oil Diffusers:

In addition to this, there are also some additional considerations that you should make if you are planning to use essential oil in combination with a diffuser.

Read on to make sure that you stay safe as can be while using your diffuser:

  • Follow the instructions:

When using your essential oil diffuser, you should make sure that, alongside all of the general information above, you are following all of the relevant information given to you by the manufacturer.

All of the safety information and precautions that you will need to follow (that will have been given specifically to you by the manufacturer) will be within the owner manual which would have come inside the box upon purchase of your essential oil diffuser.

We strongly recommend that you make sure to follow these instructions and precautions, as they will be most relevant to your specific model of an essential oil diffuser, and so in turn will ensure that you are able to safely and correctly use it.

Alternatively, if you do not have access to your owner’s manual or you have accidentally misplaced it, then you could alternatively opt to either check out the official website of your diffuser’s manufacturer or reach out to its customer service team.

More often than not, you will be able to find all of the relevant safety information that you’ll need via the product page, but if you still aren’t able to find anything helpful, you could simply reach out to their customer service team, which are usually able to be reached by email, phone or even through live chat. 

  • Be mindful of skin sensitivities:

Even though you’re planning on using a diffuser to disperse the scent of your chosen essential oils throughout the air, you should still be mindful of whether or not you or others who will be exposed to the diffuser have any skin sensitivities.

Every time that the diffuser spritzes the essential blend throughout the air, tiny little particles of the oil can still cause skin and eye irritation, so we recommend considering doing a patch test prior to use. 

In addition to this, if you yourself do suffer from sensitive skin, we also recommend that you wear a pair of disposable gloves while handling the essential oils (including the carrier oil) as this will help to reduce the chances of getting your skin directly exposed to the essential oils you are using and, in turn, lower the risk of an allergic reaction.

  • Use a carrier oil:

Though we’re sure that you’re already familiar with this next one, we still think that it’s very important to highlight.

Regardless of whether you are planning on using your essential oils for skincare purposes or to use them in combination with a diffuser, you should always make sure that you are diluting your essential oils to prevent any adverse reactions.

As a side note, if you suffer from any nut allergies, you should not use any carrier oils that are derived from tree nuts. Instead, we recommend using a more suitable carrier oil such as this one. 

  • Use in a ventilated area:

In addition to making sure that you are using a carrier oil and being mindful of skin exposure, another important thing that you should do when using a diffuser is to ensure that you are using it in a well-ventilated area.

Even though you might have used a carrier oil if you do not ensure that the diffuser is being used in an appropriate area of the home where there is consistent airflow, high concentrations of essential oils may still build up in the air, which could potentially be dangerous.

For this reason, if you are planning on using an essential oil diffuser, it’s very important that you make sure you are using your diffuser next to an open window, or spacious area of your house that gets a consistent flow of fresh air – such as the hallway next to the front door.

This will help to ensure that the essential oils do not buildup in the air, while also helping to spread the refreshing essential oil aroma across a larger distance.

  • Place at a safe distance from yourself and others:

This point ties closely to the one above, although we still think that it is important to note.

Besides making sure that the area in which you are using your essential oil diffuser is well-ventilated with plenty of fresh air, you should also make sure that you are using your diffuser at a safe distance from you and others.

While the exact distance you should keep your diffuser will be stated by your manufacturer either on the back of the box or in the owner’s manual, as a general rule of thumb, you should always remember to place your diffuser at least two meters away from you.


All in all, essential oils have a variety of different uses that can be incorporated into skincare, bathtime, aromatherapy purposes, and, of course, in combination with a diffuser.

Regardless of whichever way you choose to use them, you should always take great care to make sure that you are using them correctly, as due to the high levels of concentration – essential oils have a strong chance of causing adverse effects, especially when inhaled to excess.

For this reason, while you are using your essential oil diffuser, you should always remember to make sure that you are diluting your chosen essential oils with a carrier oil, although you could also opt to dilute your essential oils with water.

In addition to this, for optimum safety, we also recommend that you take the time to thoroughly read the instructions given to you within the manufacturer’s manual of the diffuser you are using.

This should have come in the box upon purchasing, although if you have accidentally misplaced it, you could alternatively opt to check the manufacturer’s official website, where you will be able to find all relevant safety information there.
