There are plenty of odors that find their way into our homes and nestle into our furniture, making them very difficult to ignore after a while. Sure, candles are useful and help to mask the smells of cooked foods and pets, but what happens during the summer when it’s too hot to light one? 

That is where oil diffusers come in! Oil diffusers dilute essential oils and distribute the scent all around the room to create a much more comfortable living environment for you and your household members. 

Essential oils not only generate a nicer smell for you, but some also have beneficial effects on your mental health and mood. For this reason, essential oils have become very popular in the last few years. 

Below we’ll be exploring the five best smelling essential oils for your diffuser. Keep reading to ensure you’re left with the freshest scented house possible!

Luckily for you, we’ve thought of everything and got right to the chase - our favorite best smelling essential oil is the Premium Quality Lemon Essential Oil

Here are a few reasons why we enjoy it so much, and why we think that you will too:

  • Lemon essential oil is excellent for deodorizing scents and killing household germs.
  • The bottle is incredibly large and will last you for a really long time.

Ola Prima Oils 16oz - Lemon Essential Oil - 16 Fluid Ounces

Lemon is perhaps the best deodorizing essential oil out there because the strong scent overpowers the typical household smells within minutes. The lemon essential oil can also refresh the entire room and kill germs. You’re getting a disinfecting clean without having to do anything! 

Breathing in lemon essential oil can also help relieve cold and flu symptoms and people with respiratory problems can very much benefit from lemon essential oil. This essential oil form Ola Prima is sealed in a UV protected bottle to ensure that the oil remains in the highest possible quality. 

The bottle you receive is much larger than the market average, with 473ml available rather than a small 10ml.

  • Lemon essential oil kills germs and deodorizes effectively. 
  • The bottle ensures that the oil remains high-quality for the duration of its lifetime.

Best Smelling Essential Oils for Diffusers

Choosing the best essential oil for your diffuser depends on a lot of different factors to ensure that you get the best one for you. Below we’ve included some of the most important points to remember when looking for your new favorite essential oil. 

Having a basic knowledge of essential oils and how to choose the best one for you will greatly benefit you and avoid you from having to waste money. Let’s learn more about how to distinguish between an average essential oil and the perfect one. 


The scent of the essential oil that you choose is undoubtedly the most important factor to consider when choosing the best smelling oil to use in your home. For example, if you were to choose a cinnamon-scented oil, but didn’t actually like the smell of cinnamon, you’re not going to use it as much as you would if you liked the smell. 

Sounds simple enough, right? Well, that’s because it often is simple. However, there are some exceptions to this rule, with the main one being that essential oils are often made from ingredients that you might not know the smell of. 

For example, we don’t know how Berganont smells; however, it is a very popular essential oil. If you want to opt for an essential oil that you’re unsure of the scent due to the added benefits, make sure that you check the customer reviews to see if you can get an idea of what it smells like. 

The main groups of scent that you can choose from are woody scents, sweet smells, musky odors, and floral notes. Picking your favorite scent group out of these four will greatly narrow down your search so that you can reduce the amount of time you need to scour the market for. 

If in doubt, check the scent on the internet - the last thing you want is to choose an essential oil because of its calming qualities only to find out that it smells horrible! 

Additional Benefits

Speaking of additional benefits, it’s also worth checking these to see whether they’ll benefit you in any way. For example, lavender is a great essential oil for calming you down and making you more relaxed. Alternatively, a lemon essential oil is known to boost your energy levels. 

If you use your oil diffuser during work hours and need to remain alert and awake for the entire workday, you might not want to opt for lavender oil. This could reduce your productivity and keep you from reaching your full potential.

However, if you choose a great smelling essential oil that also helps your mood or enriches your day in another way, you may as well reap twice the number of rewards!

Value for Money

Oil diffusers only require a few drops of oil to work its magic, so we doubt that you’ll be running out of essential oil within a short period of time. However, some essential oils come in larger bottles than others, and the larger bottles are often better value for the money. 

If you’re anything like us, you’ll want to get the best deal possible on everything that you purchase. Opting for a larger bottle for a lower price overall will allow you to benefit from the great smell for longer, without having to worry about repurchasing again anytime soon. 

Suitable for Use Around Pets and Pregnancy

Many essential oils are toxic to pets, particularly if it touches their skin. Oil diffusers only use a small amount of oil and diffuse it evenly throughout the room, making it less toxic for your pets. However, this doesn’t mean that some essential oils aren’t strictly forbidden for use around pets and could harm them. 

For this reason, you should always check to see whether the essential oil that you’re thinking of purchasing is safe around cats and dogs. Safe essential oils for pets include lavender, fennel, spearmint, and frankincense. 

You should also always ensure that pets have the ability to leave the room if they don’t like the essential oil that is being diffused. Cats and dogs are smarter than you think and they will remove themselves from the situation if they don’t feel safe. 

Along the same lines, some essential oils are not suitable for use around pregnant or breastfeeding women. While the list of toxic oils is shorter than that for pets, it’s also worth checking out whether the essential oil that you’re considering purchasing is safe to use if you’re trying to conceive. 

Mixing Essential Oils

Sometimes to get the best smelling essential oil, you have to mix them together. Mixing two scents can take the aroma to another level and offer you double the additional benefits, which is a great plus if you believe in aromatherapy techniques. 

There are some pre-mixed oils available on the market if you’d prefer to opt for a premixed solution. However, if you chose to mix your own oils, you’d be able to experiment more with the scents until you found the perfect blend for you. 

Especially for people only using oil diffusers to create the best smell for their house, mixing essential oils is a great option. If you were planning on doing this, you might want to opt for an essential oil kit with multiple oils included. 


Inhaling essential oils from a diffuser is one of the quickest ways to get the oil into your bloodstream. Don’t freak out - the majority of essential oils are not toxic for humans to inhale as long as you use them correctly. 

Having said that, you should always use your essential oils correctly and safely to avoid accidentally poisoning yourself or other family members. When you’re diffusing oils, you should always ensure that the room is well-ventilated and that you follow the correct dilution guidelines. 

Most essential oils will come with their own guidelines, so don’t only follow one set of instructions. Some oils are more potent than others and therefore shouldn’t be used in such a high quantity as other diluted oils. 

Frequently Asked Questions

Why can I not smell my diffuser?

When you diffuse the same essential oil regularly, your body gets used to the smell rather quickly and therefore stops reacting to it. In other words, your senses go ‘blind’ to the scent of the oil and therefore stop registering the scent. This is the most common reason why you stop being able to smell your diffuser after a period of time.  

What are the best sweet-smelling essential oils?

Bergamot is a great scented essential oil as it boasts a fruity aroma that inspires the body to become lively and uplifted. Lemon oil is sweet and tangy, with the benefits of waking the body up and getting it ready for the day ahead. Chamomile is another sweet essential oil; however, this one relaxes the mind and is best used before bed. 

Other sweet-smelling essential oils include grapefruit, jasmine, orange, and rose oil. 

What are the best musky-smelling essential oils?

Musky scented essential oils are less sweet and better suited for people who enjoy earthy smells rather than sickly sweet alternatives. Citronella offers a citrusy scent that purifies and freshens the entire room of odors. Frankincense relaxes and focuses the mind all at once, and patchouli offers a romantic scent that isn’t overpowered by sweetness. 

Other musky-scented essential oils include woody oils such as cedarwood, sandalwood, and pine needle oil.
