A Little Background
Essential oils are a great addition to any home because they add a lot of calmness and relaxation. Most homes that have air conditioning units or even those without can benefit from an essential oil diffuser for the guests and for the whole family. Each unique oil can have a different scent that is not very strong unlike perfumes that are chemically made so they won’t cause allergic reactions when you breathe them.
An essential oil, when purchased from a reputable brand, should always be fully natural and extracted from renewable sources like plants. Essential oils have come a long way in history, and today, they are still being used for various therapeutic purposes or even just acting as an air freshener for your home. Do take note that essential oils can be expensive so they can only be afforded by most middle to high class homes.
To diffuse an essential oil in your home, you need an essential oil diffuser. It is like a humidifying device that spreads the mist in the air from your essential oil so that you can be able to breathe your favorite scents. They can diffuse faster and more evenly and can help your home stay fresh and clean smelling, if you choose natural scents that are not too strong and just right for people.
Using an essential oil for your home scent can be a little bit of an investment, but it will be worth it if you often receive guests. During the rainy days or cold days, when the air is making mold grow faster and bacteria could spread, you need to both purify the air and make it smell good. Aside from an air purifier, an essential oil diffuser can be a great addition to your home.
There are many kinds of essential oil diffusers – from electronic ones to manual candle burners. They all work differently and each have their own purposes and kinds of oils you can place. But the great thing about essential oil diffusers is that you can mix your own flavor or scent of essential oils so you can customize depending on the type of mood you want for your home or room.
Whichever essential oil diffuser that you choose, it is important that you pick the right one with the features that are useful, such as timers, lighting and the like. It is also crucial that the essential oil diffuser that you pick will accept nearly all kinds of essential oils for you to mix. In addition to that, you will need an essential oil diffuser that is easy to operate so you can sleep well while it runs.
How We Picked
In choosing the best essential oil diffuser, you must make note of the following:
Style: the style of an essential oil diffuser should be your first choice. There are many kinds of essential oil diffusers out there, such as the bowl shape or the taller one. Some of them have lighting while some don’t, and just have a rustic wood finish for a touch of class. You should depend the style of the essential oil diffuser on where you will place it in your home so that it can cleanly match your existing furniture.
Manual or electric: do consider whether you want an essential oil diffuser that is manual powered (candle burner) or electric. Take note that an electric diffuser is easier to operate than the manual one because it can run even while you are asleep and won’t cause fires unless it is a low quality brand that does not have electrical protection. On the other hand, a manual essential oil diffuser can have better and more natural diffusing technique.
Controls: the ease of controls should be consider in an essential oil diffuser. It should be easy to set the timer, to adjust the lighting and to control other factors. The switches should be conveniently located in the essential oil diffuser to make it easy to setup.
Lighting options: most electric essential oil diffusers have lighting options that you can switch. Most of these diffusers have multiple colors for their design and can also cycle on the colors. You can use the essential oil diffuser as a nightlight or as an additional décor at home for the guests. If the lighting is adjustable, you can complement the colors of your home or room.
Oils you can use: do consider what kinds of oils can be used in the essential oil diffuser, as stated in its user’s manual. Certain oils might not work well with all essential oil diffusers so you should know which one works well.
Warranty policy: consider the warranty policy of the essential oil diffuser, its durability, its return period as well as which parts are covered by the warranty.

Other Frequently Asked Questions
Q: What are the different kinds or types of essential oil diffusers?
A: The different types of essential oil diffusers that work to diffuse oils are the following, each with their own purposes:
The ultrasonic diffuser is the essential oil diffuser that you will most likely see in the market. They are the safest and can be the cheapest as well and they are the ones that will most likely have a certain style or lighting effect. Here are the pros and cons of the ultrasonic diffuser:
· They give you a fine mist that is evenly dispersed throughout the room.
· They don't give you a lot of noise levels, so they are good to sleep with.
· They won't give you a problem with losing the quality of the oils, since they don't heat up like candle burners.
· You won't have a problem with potential house fires because you are not using candles or heat.
· They have timers so they can automatically shut down when you want them to.
· They are not advisable for use with carrier oils.
· Citrus oils and other thick oils might be okay but you need to thoroughly clean the essential oil diffuser afterwards.
· Some can still be higher priced depending on the model.
The passive diffuser is the kind of diffuser that does things manually without the use of electronics. They are widely available and are the cheapest because of their ease of setup. They can either be a porous stone or some other natural diffuser. Here are their pros and cons:
· They are super easy to setup and the simplest of all.
· Because they are all-natural, you don't need to spend a fortune on them.
· They're great for small rooms or on-the-go diffusing.
· They’re not good for longer lasting scents.
· You have to manually do things in this passive diffuser.
· They don’t have the fancy lighting and design.
The nebulizing diffuser is kind of like the ultrasonic one but the catch is that no water is used. They are typically used for therapeutic or respiratory problems so they aren't meant for everyday use. They can be more potent and can also handle thicker citrus oils. Here are their pros and cons:
· They're great for respiratory problems and illnesses.
· They can be used even with thick citrus oils.
· You don't need water for them to run.
· They get into your bloodstream easier than ultrasonic diffusers.
· They are more expensive than ultrasonic diffusers.
· The scent doesn't last longer than ultrasonic diffusers.
· You still can't use carrier oils as well as resinous oils.
The reed diffuser is also a manual type of essential oil diffuser, which uses a wick or stick that diffuses the oils from the jar or vase. In some cases, figurines can act as the jar and they may hold a stick or wand so you can add them to your home décor and they won't even notice that it's actually an essential oil diffuser. Here are the pros and cons of this diffuser type:
· They are manual so they don't use electricity at all.
· They add style to your home or room, especially if you choose a unique design.
· They can also act as decor for certain restaurants and public places.
· They are affordable in general.
· You can use them in a shop, public place or even your car instead of your air freshener.
· Carrier oils can be used in this essential oil diffuser.
· They may not be powerful enough to diffuse oils into the room.
· The scent may not last long enough.
The heat or candle diffuser is the one that uses ceramic heaters to diffuse the oils. They are also called ceramic diffusers and like reed diffusers, they run manually (some are electric, though), but you need a candle to light them up. They can also be made of heat glass or soap stone and can take on various shapes and sizes. Here are the pros and cons:
Heat (Candle) Diffuser
· They have a stylish look that can be used to decorate your home or space.
· They are easy to use with pouring drops of oil into the top bowl.
· They don't consume electricity at all (for the manual candle types).
· Some of them are cheaper and more economical than ultrasonic diffusers.
· You can use them with carrier oils as well.
· They generate heat so it might damage the oils when you diffuse them in the air.
· Candles that are left unchecked can cause potential fire hazards.
· Even electric models that heat up can cause fires.
The fan or travel diffuser is the best for use in a car or while travelling. If you have a power bank or a USB port, you can easily use this fan type diffuser, which can be plugged to diffuse your essential oils to keep your car smelling fresh in the rainy days. Here are the pros and cons of this type of diffuser:
Travel (Fan) Diffuser
· They are portable and can be carried anywhere.
· They can be used in the car or any vehicle.
· They're great for the rainy days when you car smells funky.
· Some of them can be cheaper.
· They may not be as longer lasting as regular diffusers.
· Some argue that fanning might decrease the quality of the diffused oils.
The USB diffusers are even smaller than travel diffusers, and are meant to be plugged into your laptop or power bank so that you can use them in very small spaces or on the go. They are mostly sold by Chinese companies so they are basically the cheapest of all electronic type oil diffusers. Here are their pros and cons:
USB Powered Diffuser
· They are great for small spaces.
· They are super affordable.
· Anyone can use them for as long as they have a USB port.
· They can be used in a laptop.
· They don’t last long compared to regular diffusers.
· They may not be as durable as regular diffusers.
The novelty diffuser is also a manual or passive diffuser that can be in the form of a necklace, pen or other jewelry and novelty items that have small passive diffuser elements. You can give them as a gift or use them for everyday needs, and most people won't even realize that they are essential oil diffusers. Here are their pros and cons:
Novelty Designed Diffuser
· They look cool and unique and people won't realize they are diffusers.
· You can use them anywhere and anytime you like.
· They are affordable.
· They don’t last long for their diffused oils.
· They probably won’t cover an entire room due to their size.
Q: What are the different benefits of an essential oil diffuser?
A: The essential oil diffuser has the following benefits for your home and your well-being:
You can get a lot of relief from stress with an essential oil diffuser. After a long day of work or school or any kind of career you are into, there is nothing like the stress relief that an essential oil diffuser can offer with its different oils you can choose. There are specific oils that are meant for relaxing, such as frankincense, rose, chamomile, bergamot and lavender.

This is a great way to use your essential oil diffuser in your deck, terrace, porch, patio or outdoor area where bugs and insects might ruin your day or cause other problems like illnesses and bug bites.
You can even use an essential oil diffuser as a replacement to incense and candles. If you use regular candles then you may be bound to inhale harsh chemicals, unless you have homemade wax candles. On the other hand, an essential oil diffuser can also be a replacement for scented candles since they don't give a fire hazard (unless you have a heat diffuser).
People with allergies can benefit from an essential oil diffuser. Eucalyptus and tea tree oil are great allergy treatment oils, as well as basil and peppermint. If you have these oils in your essential oil diffuser, you can help your itchy throat and allergic rhinitis to level down a bit because it can help improve the air quality in your home.

Peppermint can also help you boost sporting energy while eucalyptus and pine are good for studying or clerical work.
An essential oil diffuser can also be a natural air freshener instead of depending on commercial chemicals that you may have been using. Their scents are not very irritating if you use authentic and natural oils instead of fragrance oils or air fresheners. The essential oil diffuser only uses natural oils and essential oils so they don't give that off-putting smell that your parents may not like.
You can also set the mood in your home with an essential oil diffuser. For example, Christmas can call for pine and cinnamon while a romantic date can be filled with rose, jasmine, ylang ylang or sandalwood. Setting the mood is one of the best benefits of an essential oil diffuser.

Q: What is the difference between an oil burner and an essential oil diffuser?
A: An oil burner is different from the essential oil diffuser due to the following:
The oil burner is actually called the ceramic diffuser or candle / heat diffuser. They are not very good at diffusing oils because the heat kills some of its components and result in a less fragrant or less effective diffused oil in the air. They also have a tendency to cause fires.
The essential oil diffuser usually refers to the ultrasonic diffusers that use water and not heat is required to diffuse the oils into the air. They may be more expensive than oil burners but they are safer and most of them are quiet and stylish.
Q: Why is it not a good idea to use fragrance oils in an essential oil diffuser?

· Some dark spots may form on the body or housing of the essential oil diffuser.
· The diffuser might not work anymore if you keep using these fragrance oils.
· They may also not be that good for your health because of their chemicals that are similar to perfumes.
Q: What could be wrong if my essential oil diffuser stops misting all of a sudden?
A: The essential oil diffuser may not mist at all if you have the following problems:
You may be using purified water or distilled water, which does not contain many minerals. Tap water is the best way to get your diffuser to work because it still contains the minerals that are needed to carry the oils into water vapor.
The essential oil diffuser may need to be cleaned on its ceramic disc. Having an unclean essential oil diffuser can make it clogged and not run at all. You can use soft cloth plus warm water and alcohol if needed, to remove the residue left by the oils.
Consider lukewarm water instead of cold water in your essential oil diffuser. If you use water that is too cold then the essential oil diffuser might not run at all, since most essential oil diffusers are most likely meant for lukewarm water.
Q: What areas of the house should I avoid with an oil diffuser?
A: An essential oil diffuser should avoid the following:
· Hardwood - consider keeping it away from hardwood items like furniture, tables, chairs, ceilings, dressers and the like. This is unless they are specially sealed and finished with coating.
· Delicate fabric - consider keeping it away from certain delicate fabric such as bedding sheets, curtains and the like.
Q: How many drops of oil can I add to an essential oil diffuser?
A: Adding drops of oil to your essential oil diffuser can depend on different factors such as the following:
The size of your room - you need to add more drops to your essential oil diffuser if you plan to use it for a large room such as your living room or master's bedroom or even your dining area.
The purpose of the oils - make sure you choose the right oils for the right job. For instance, if you want to keep your indoor air fresh then you should add just the right amount. Otherwise, you should add more if you have pets or you just finished cooking.
The type of oils - some oils are longer lasting than others so you may only need to add a few drops instead of many. It can also depend on the brand that you choose.
· On the average, 5 to 15 drops is a good number for most common oils like lavender but you can increase that number if needed.
· You can also mix oils depending on your preferences instead of focusing on just one oil.
Q: Is there a difference between natural oils and an essential oil?
A: An essential oil is different from natural oils with the following:
An essential oil is simply the basic form extracted from plants or plant parts such as the leaves, roots, flowers, stem, bark and the like. They are a single flavor or plant and are pure and concentrated.
A natural oil is a mix of various essential oils to form a different kind of oil or substance. It involves more chemical processing but still comes from natural ingredients so they are still safer than fragrance oils.
Q: Is there a difference between essential oils and fragrance oils?
A: The two special oils are different, and here's how to tell them apart:
Essential oils come from natural sources and are usually more expensive. They come only from reputable stores and brands and it is hard to look for them in retail and novelty stores. They can be taken internally or used topically, other than being used in an aromatherapy diffuser.
Fragrance oils, on the other hand, are simply chemical replications of essential oils and not the real thing. They are only meant for scent burning and not for essential oil diffusers because they contain harsh chemicals. However, they are still beneficial somehow because they smell good.
Here is a chart comparing the two types of oils:
Essential oils are very expensive per bottle or set.
Fragrance oils are cheaper to buy for the average person.
Essential oils can be applied topically, taken internally and used in any diffuser.
Fragrance oils are limited to reed diffusers, manual diffusers and cannot be taken internally or applied topically due to the chemicals.
Essential oils do give off more natural scents.
Fragrance oils, when properly formulated, can still give off a similar scent to essential oils.
Essential oils are harder to manufacture because not all countries in the world have the same crops (e.g. lavender doesn’t always grow on Asian countries).
Fragrance oils are easier to manufacturer through laboratories.

A: An ultrasonic diffuser can differ from a reed diffuser and a scented candle based on the following facts:

Doesn’t need any kind of setup at all.
Candle drops are definitely frustrating to clean up.
Q: Why do people choose ultrasonic diffusers over burners?
A: An ultrasonic diffuser has more advantage over burners due to the following:
· Heating can change the chemical composition of your essential oils, which can decrease its quality, so ultrasonic is the way to go.
· Burners are more prone to house fires so it's best to stick with ultrasonic diffusers if you want to sleep with aromatherapy on your side.
· Evaporation doesn't happen right away to your essential oils with an ultrasonic diffusers, so you won't lose them that fast.
Q: What do I need to consider when choosing essential oils?
A: When you want to shop for essential oils , you must make note of the following:
The price of essential oil is always something you should prepare for. Unlike perfumes and fragrance oils, true essential oils are hard to find and difficult to manufacture, so they will usually cost a lot more than you would expect. If the essential oil is not too pricey then there is a chance that it might be fake.
The purity of the essential oil must be stated in its label. It's hard to determine this if you're not a chemist or expert with essential oils, so it's best to consult local groups and those who know which brands of essential oils are the purest despite their pricing.
Consider the label of the essential oil and what is written there. It should be organic and should display the manufacturer's name, expiration date, distillation date, country of origin, botanical name and indicate that it's wild crafted or not sprayed with chemical based fertilizers. It should also have seals of testing for GC/MS and approved by NAHA. Some can indicate “therapeutic grade” but be careful as some are just bluffing about this.
Q: Which companies are the best to get essential oils from?
A: There are so many companies today that are offering essential oils, but there are certain companies that stand out, such as:

Bedroom: by adding an essential oil diffuser to your own room, you can sleep properly or study better and help yourself relax with the oils. Depending on what oils you put in, you can have a better feeling when you turn on the essential oil diffuser at night to help you relax.
Hotel room: an essential oil diffuser can be a great air freshener and mood booster for guests in a hotel so it's a good idea to put one in each room to serve the guests. After all, hotels are supposed to pamper your guests since they are staying for the night.
