Recently, recommendations about using oil diffusers have mentioned that they have the ability to improve energy levels, sleeping habits and health. The scented steam that comes out of the diffuser, along with the colored lights that are available will help you relax, and can be a much safer alternative to candles and incense if you are concerned about fire hazards, or tend to be forgetful about leaving them on in your home. Even if you are not interested in these health related reasons, these diffusers can be used simply to make your home or apartment smell delicious and homey every time you walk in. Below is a comprehensive list of the best oil diffusers you can buy.

#1 Gold pick (Winner): URPOWER 300ml Aroma Essential Oil Diffuser

URPOWER 300ml Aroma Essential Oil Diffuser Gold Pick

View it on Amazon for $56.99*
*Price typically updated every 24 hours. Current price may be different.

2016-gold-winnerThe first product on our list has a very traditional look that seems like something a spa or a Yogi would use. The outside of the oil diffuser has a wooden base as well as a wooden composure traveling up a majority of the spine. At the very top, a cool colored peak arises where the steam and oil would come out. Overall, it has a very natural and calming composition.

One of the interesting aesthetic features of this diffuser is that if you so choose, you have the ability to change the colors on it if there is a certain one that pleases you, or if you would like it to match the décor in your house. The options you can choose from are all pastel, and include: cream, pink, orange, green, blue and purple. Each of the colors is faint and will not omit any harsh light. The color of your choosing will be filled in at the top where the peak is, as well as a small thin line traveling throughout the base of the diffuser. In the case that you want the machine to emit more light, you will also have the option to change the setting to a high color or low color based on how bright you would like it to be. If you do not want it to stay on a single solid color, you also have the option to have it switch the colors every so often.

A Wooden grain design is used so that the aroma diffuser can blend into your home if you so choose. URPOWER describes it as an ultrasonic humidifier and air purifier in one. The company boasts that with this product, you will be able to escape the hustle and bustle of modern life with the soothing aromatherapy it offers. The entire container can hold approximately 300ml of water that the oil will diffuse into and spread throughout the air. It is completely up to you what scent you want to choose and it is easy enough to refill when you run out. When the steam comes from the top of the peak, it is an ultrafine mist that is barely noticeable to the eye. Place it in any room in your house and it can refresh the room up to 269 square feet.

Able to run continuously for ten hours on a timer, it will automatically shut off once it has passed its time limit in case you forget about it. If you would prefer that it be set on a shorter timer, this has the option to bet set at intervals of 60, 180 or 360 minutes. When the time is up, or the diffuser runs out of water, it will automatically shut off until you turn it on again, or refill it with water. One of the best features the URPOWER offers is the guarantee that it will run quietly during the day. No more annoying hissing that can come from cheaper models and has the possibility to drive you crazy. This will simply work quietly in the corner while it makes your home smell fresh and clean.

Taking up a small space on your counter, the diffuser measures at 6.6 by 4.75 inches. It is big enough to be readily noticed, but small enough that it won’t become an eyesore. The vibrating sound waves that will be emitted from the container are used to create a soothing, scented mist. The air coming from the diffuser will also act as a humidifier in the room and add moisture to the air. This is an important thing to consider when you purchase this, as you want to be careful with putting it around things that are relatively sensitive to the moisture.

Instructions do come with the machine, and ask that you use regular tap water. This is especially convenient considering that some require you use a specific distilled or filtered water. With this however, you can feel free to just run it under the sink until it is full. This specific diffuser is available on Amazon for $43.99.

#2 Silver pick (Runner-up): InnoGear 100ml Aromatherapy Essential Oil Diffuser

InnoGear 100ml Aromatherapy Essential Oil Diffuser

View it on Amazon for $69.99*
*Price typically updated every 24 hours. Current price may be different.

2016-silver-winnerWith our second option, InnoGear has created a smaller, yet just as powerful oil diffuser for you home. Featuring a taller and slimmer design, the InnoGear diffuser can hold about one third of the amount of water our first option could. While neither of the picks will be taking up an obscene amount of room, this one is great if you find yourself extremely limited for space options. The design is a solid plastic one from the base up with no false wood look. However, if you were still partial to being able to change colors, this one will still give you that option. Again in a light pastel hue, you can choose from seven different colors including: purple, green, light blue, turquoise, royal blue, yellow and red. Additionally, you have the option to set it to two different modes, the first one will change the color periodically and the second will stay on one solid color for the duration of its use.

Equipped with the option to intermittently mist the room every thirty seconds, or spray continuously, this machine gives you plenty of options to choose from, and wiggle room to customize it however you like. Boasting lovely fragrances that will lift your mood and relieve stress from your long day, it will also mask any stubborn odors around your house. This is a great option for those who have kids running around the house, or pets who don’t like to get bathed as often as they should. One of the fun additional features of this diffuser is that it comes with a link to access fifteen free eBooks that will guide you on using essential oils and a variety of aromatherapy recipes.

The “whisper-quiet” ultrasonic operation will keep any noise from distracting you as you go about your day, and will not omit any sharp-piercing noises that are common with this type of diffuser. Also doubling as a humidifier, it will add moisture to your home and help to keep plants and other areas of your house from becoming too dry. Just as with the first diffuser, this is an important thing to consider when you are purchasing a diffuser as it will add moisture to the air. If you have any sensitive paintings, or objects in your house that prefer a dry environment, think about placing this elsewhere.

While this does not have options to set a timer for how long the diffuser will stay on, it will automatically turn off as soon as the water runs out. This is a wonderful option since if the diffuser stays on when there is no oil, it will simply keep drawing from the oil container and not diffusing it into the air. This can also pose a fire hazard if it keeps running without water. Since it does have the option to run in a continuous or intermittent mode, it can run for about three hours continuously, or 6 hours intermittently. If you have kids that tend to run around the house knocking object over, this does not emit any hot water or air so they will not burn themselves if they do happen to crash into it. The mist is actually a bit chilly, and poses no threats to your family.

This item is sized at 3.9 by 5.7 inches, which will only take up a very small portion of space on your counter top. If you do not have any outlets near where you want to place it, the diffuser does come with a 6 foot long cable so you don’t have to worry about not having a long enough cord. Included in your purchase is the aroma diffuser, a wall charger, one user’s manual, and a measuring cup for refilling the machine so you don’t have to worry about not getting the perfect amount every time. In case you are still a bit skeptical about this purchase, it does come with a 45 day money back guarantee if you just plain don’t like it. No questions asked. In addition the money back guarantee, it also comes with an 18 month warranty in case anything does go awry. According to the reviews, you will not have to worry about that happening though. The product is available on Amazon for $19.99.

#3 Bronze pick (3rd place): AromaSoft Aromatherapy Essential Oil Diffuser

AromaSoft Aromatherapy Essential Oil Diffuser

View it on Amazon for $49.99*
*Price typically updated every 24 hours. Current price may be different.

2016-bronze-awardThis AromaSoft option looks almost identical to the InnoGear diffuser on our list. Depicted as a very powerful diffuser, it will be able to spread its aromas around the entire house in no time, and have everything smelling fresh and clean. With a whopping 24 volts of energy coming from the machine, this is guaranteed to be powerful and make even a very large room smell wonderful. With its compact size, it is marketed as portable, so you can take it with you wherever you go. This is a great option for those who do a fair amount of travelling. Living in hotels that are far away from home don’t always exude the feeling of home comfort, especially when there have been many other people in the room before you. You can bring this with you and spread its amazing aromatherapy scents around the room, making it seem even more like a home away from home. It will also act as a humidifier and add moisture to the dry air around you.

Super quiet to the point that you do not even realize it is in the room, the power it uses to quickly spread the scents throughout the house does not affect how noisy it will be. Guests will not notice it unless you have it set out in the open, and it will just quietly make your home smell amazing. As with the previous models we have discussed, this also has seven different color settings you can set the diffuser to. If you prefer it to stay on one color the entire time it is on, that is also one of your options. If you would like it to gently cycle each of the different colors, they will slowly fade in and out and it moves onto the next. The colors it offers are pink, green, blue, light blue, cream, turquoise and red.

Equipped with an automatic shut off, it can automatically turn off when it senses little or no water inside. Simply fill it up, turn it on and walk away, and your house will be filled with delicious scents the entire day. No special water is needed to keep the diffuser running either. Unlike some options, you will not have to fill it with spring water or filtered water. Simply run it under the tap and it will start working right away.

Once again having similar components to the InnoGear option, you can choose whether you want it to continuously emit aromas throughout the air, if it you would like it to do so intermittently. With 30 second intervals or about six hours of continuous run time, you will not have to worry about keeping an eye on it during the day.

Backed with a lifetime guarantee, if you ever find that you do not like it, or find any issues with it during the lifetime of the product, you can return it for a replacement or a refund with no questions asked. This product is available on Amazon for $29.87.

#4 Budget pick (Best cheap): PuraSense Essential Oil Diffuser

PuraSense Essential Oil Diffuser

View it on Amazon for $29.99*
*Price typically updated every 24 hours. Current price may be different.

2016-cheap-budget-pickMake no mistake that least means least or that cheap means bad for this product. PuraSense has found a way to make a great product that will last you a lifetime and do exactly what needs to be done. Their essential oil diffuser has an oblong shape that stands a bit straighter than the other options on our list, as opposed to being more round and teardrop shape. The bottom of the diffuser features a white plastic that fades way into a transparent container that holds the water. The entire machine looks very similar to a thick candle.

Also boasting no noisy buzz that comes with some of the diffusers, this will sit quietly in whatever corner of the house you put it in and simply make everything smell wonderful. It is also uniquely compact and portable if you choose to take it with you when you travel. Measuring at 5.1 by 3.7 inches, it is the smallest diffuser on our list, but still manages to pack quite a punch.

As with the previous option, this also comes with a lifetime guarantee that you will love the product. If for any reason you are not 100% happy with PuraSense, simply return if for a replacement or a refund with no questions asked. This diffuser is available on Amazon for $29.99.

Feel free to choose from your favorite colors when you are using this, as you can change it to blue, red, green, purple, pink, orange or a plain white light. You can also choose if you want it to stay on a specific color or if you would like it to change the color. If you do not want it to emit a light, you can also turn that setting off. The description of the machine mentions that it will run for approximately 15 hours at a time before it automatically shuts off, but most of the reviews state that they can only get about 9 hours out of it. If this is a concern to you, or if you need something that lasts longer, you may want to look at different options.

Pre-purchase considerations


All of the diffusers on this list feature different sizes as well as how much water they can hold. For the most part, all of them will give you the same product by releasing your choice of a scent into the air and making your entire home smell great. However, if you are living in an apartment or a college dorm where space is extremely limited, a smaller one might be a better option. Just because it is smaller does not mean you won’t get the same great quality. It simply means that it will take up less space and will be much less noticeable.


As with space being an issue, so can the length of time it takes for the diffuser to run out. All of them come with the setting that will turn the diffuser off after a specific period of time has passed so that the oil will not be wasted and it does not pose a fire hazard to you. However, how big the tank is will determine how long it will last without you needing to fill it. For some, you might want to be able to leave your house all day and come back home to the diffuser still running and your home smelling great. For others, it would be ideal to have it turn off while you aren’t there so it does not waste any of the oil.


Maybe you just have plain bad luck when it comes to purchases. Maybe you have children or pets that tend to find the most valuable thing in your house and knock it over two days after you purchased it. Either way, an extended warranty might be a necessity for you if you have any of these issues. Two of the above diffusers come with lifetime guarantees which are a wonderful thing for any product. No matter what happens in your life no matter if it breaks, or simply stops working, you can get a new one or a refund free of charge without any questions asked.

Scent Strength

Do you want just a little wisp of scented air coming from your diffuser? So small and quiet you barely notice it’s even there? Or maybe you want a strong steam coming from it so that it quickly fills your house with its delicious scent and you always know when it’s on. Your personal preference is all that matters here, and if either of these are important to you it is definitely something to consider.

Conclusion (Wrapping it up)

Overall, there is something in this list for every single person who is interested in purchasing an oil diffuser. All of them have the similar qualities of having amazing reviews on Amazon. No matter what you choose, it will fill your home with comforting and relaxing scents, as well as let you choose what colors, if any, you want the diffuser to show. Whatever your needs or preferences may be, there is something here for everyone, and it is guaranteed to be a product that you will love.
