Essential Oils For Diffuser 300pxWith so many essential oils to choose from, it can sometimes be difficult to know where to start when it comes to using them.  Diffusing is a great way to enjoy the many benefits essential oils have to offer – not only can you enjoy the beautiful aromas of the oils, but also their many therapeutic advantages.

Regardless of your personal favourites, below I have listed the 5 best essential oils for diffuser use.  With these 5 you can be guaranteed of having something to help with anything – respiratory problems, mood enhancement, antiviral, antifungal, antiseptic and so much more.

Each of these oils can be used alone, or in combination with the others.  This gives you plenty of options to achieve the desired result while having fun experimenting.


Lavender Oil Field 300pxLavender is not called the swiss army knife of essential oils for nothing.  It truly is the first oil that should be included in any collection, so if you only want to buy one, make sure it is lavender.  It is the best oil for a diffuser, either alone or in a blend.

When diffused, lavender has a calming, relaxing and balancing effect on the emotions.  It can be used to help irritability, insomnia, nightmares, stress, nervous tension, hysteria and is generally balancing to the psyche and the body.  This makes it perfect for any stressful situation and in bedrooms.

The beautiful fragrance of lavender is another big benefit of diffusion.  But not only does it smell good, lavender will get to work by repelling viruses and bacteria.  It also creates an unfriendly environment for microbes while cleansing both the air and body of toxins.

Lavender is a universal oil and can be blended with most oils, especially citrus oils.


Eucalyptus Oil Leaves 300pxRenowned for helping with respiratory ailments, eucalyptus is another must have essential oil for a diffuser.  It works as a decongestant and helps breakdown mucus when coughs and colds are around.  Snoring is another condition it can help with.

Highly antiseptic, while also being very affordable, eucalyptus is one of the strongest essential oils to fight viral infections like flu and chicken pox.  For general well being, it also boosts the body’s immune system.  So, when sickness is around, this is the oil for your diffuser.

The fragrance of eucalyptus is sharp and camphorlike.  It can be quite strong so sometimes it is best blended with another oil, such as lavender or lemon to reduce the powerful odor.

Another use for eucalyptus in the diffuser is to repel mosquitoes and other insects.  Use alone or with lavender, lemon or tea tree oil for a great smelling repellent.


Lemon Oil Sliced 300pxLemon is top of the list for fighting viruses and bacteria as it is a powerful air disinfectant.  If illness is present, diffusing lemon oil will help to kill germs and purify the air.   Plus, it has the huge bonus of making house smell wonderful and clean.  

Aromatically lemon essential oil promotes health, healing, physical energy and purification.  It’s well-known citrus scent is invigorating and makes a room ‘lively’.  So not only is it great for the immune system, it is very uplifting and a mood enhancer.

Lemon blends well with eucalyptus, lavender and peppermint.



Peppermint Oil Leaves 300pxIf you are tired, worn out but still need to do something, then peppermint is the oil to diffuse.  It stimulates the mind, helping with memory and mental performance.  It gives you ‘purpose’, physically clears the head, leaving you feeling bright and fresh ready for mental effort.  Definitely not an oil to diffuse at bedtime!

One of the best known uses for peppermint is as a digestive aid.  When inhaled, it can help with nausea and reduce motion sickness.

Peppermint is also useful for reducing fever and headache.  It has a natural cooling effect to help bring temperature down.  When combined with lavender it is even more effective and the two oils combined enhance the action of the other.

Rose Geranium 300pxGeranium

The only flower oil included in the list, geranium is known as the ‘balancer’, both physically and emotionally.  Not only does it smell beautiful, the scent is good for those who feel overly emotional and need more stability.

It is also works as an antidepressant, helping to release negative memories and return a person to a peaceful, joyful state.  So for an overall feeling of peace, wellbeing and positivity, geranium is the one of the best essential oils to diffuse.

Geranium can be used as an insect repellant when diffused alone or in combination with other repellent oils like lemon and eucalyptus.  It is particularly effective against flying insects.

I must admit that geranium oil is my personal favourite.  There is rarely a day that I don’t use it in some way.


It is never an easy task to decide on just 5 essential oils for a diffuser to recommend.  There are plenty of others that on any given day, I might prefer e.g. tea tree, orange, pine, cypress, cedarwood, lemongrass and so on.  And quite often, a blend of oils is what I most prefer.

However, if you are just starting to enjoy diffusing essential oils, then start with the 5 oils listed above.  They are the best all rounders that will never disappoint and the perfect start for your diffusing experience.
