Best place to put an essential oil diffuser featured image

Essential oil diffusers are a great way to improve your quality of life and relax. There’s something really special about enjoying a natural, relaxing scent filling a room anytime you like.

When getting started with mine I had to learn the basics. I’d love to help you by sharing what I’ve learned along the way.

I’ve put together a great post packed with info and facts about aromatherapy (essential oil) diffusers. I’ll also answer your main question: What’s the best place to put an essential oil diffuser?

Where should you put an essential oil diffuser?

The truth is that there really isn’t a “perfect” place to put them. However, there are some basic guidelines that can help and will work for nearly everyone.

Essential oil diffuser placement tips
  • Although you can use them on a floor, placing them at least 2 feet above the floor is ideal, similar to humidifiers
  • Bedroom: Placing your diffuser a few feet from your bed is recommended. A minimum of 3 feet or so is good
  • Don’t put your diffuser where it will be constantly exposed to sunlight (Ex.: near a window)
  • Avoid placing it on top of or very close to wooden surfaces subject to moisture or water damage. A tray or other water-resistant cover underneath it can prevent problems from mist droplets or spilled water
  • A non-metallic, level surface is ideal. Do not place on carpet or similar surfaces that can become damp
  • For best results, place your diffuser closer to the center of the room or even to one side, where ever convenient (this is a “nice to have” recommendation and not essential)

As I mentioned above it’s definitely best to keep them away from wood surfaces (or use a material underneath them to protect the wood).

Based on my personal experience I can say it’s very easy to spill water during everyday maintenance & use. You also don’t want stray water falling on your favorite furniture.

It seems like every other time I refill my diffuser’s water tank some droplets get on my shelf.

Diagram – Basic ideas for where to put your diffuser

Diagram showing recommended placement for an essential oil diffuser

Shown: A simple diagram showing examples of where to put your aromatherapy (essential oil) diffuser. While it’s not “critical” to follow these by any means, they’re a good rule of thumb to follow. I recommend keeping your diffuser several feet from your bed on a good, flat surface above the floor. It should be a surface that won’t be harmed by water droplets or spills. Additionally, it’s a good idea to keep the unit a few feet from your bed as well.

As shown in the diagram I’ve provided, here are some good basic rules of thumb for where to put your diffuser:

  • Out of direct sunlight such as near a window
  • Several feet from your bed or where you sleep (use 3 feet or more as a rule)
  • 2 feet or more above the floor
  • Away from furniture or other items that can be affected by water

These are just the basics “at a glance.” Read on and I’ll add more detail as we go.

Should a diffuser be on the floor or a table?

Image showing essential oil diffuser placement on a floor or table guide

You can put your diffuser on either a table or the floor. However, at least about 2 feet from the floor is best. Your essential oil diffuser’s vapor mist will distribute evenly within your room over time. Additionally, both they and I recommend you don’t use them alone without something to protect the surface from spills or water droplets.

Placing your essential oil diffuser at least 2 feet above the floor is ideal. If you’re wondering why it’s because they’re actually smaller versions of cool mist humidifiers which manufacturers recommend be placed at least 2 feet above the floor.

That’s because as they work, humidifiers and diffusers create and output water vapor that doesn’t rise the same way as others. For best results they need to be placed higher in the air.

If placing it on a shelf, desk, or some type of table, be sure it’s stable and not prone to accidents. You definitely don’t want anyone accidentally tipping yours over so be careful where you put it!

Protect against stray water

Much like humidifiers, it’s best to use them with some type of tray or protective material underneath them. That way you’ll be sure to avoid problems from spilling water or water droplets produced by the output nozzle.

In my personal experience, it really depends on the particular design and operation of the one you’ve bought. Some are messier than others when it comes to how easy they are to spill and if they produce random water droplets that can fall on your furniture.

Use water-safe surfaces or protective material

As not everyone has a water-resistant table to use, find an item that’s water-resistant to cover the area around your diffuser. Pick one that’s large enough to cover the area around it by about 1/2 feet to 1 foot in size as a rule.

Yes, you can use a diffuser on the floor if you need to. They’ll still work well but not nearly as efficiently for filling your room with scent, so I would recommend against it.

If at all possible raise them above the floor as I recommended above.

Either way, don’t use them on the carpet. Carpet is notorious for allowing water to become trapped and build up over time, potentially leading to more problems.

Keep them out of direct sunlight

Diagram drawing warning against placing essential oil diffuser near a window

Don’t place your diffuser near a strong source of sunlight and heat like a window. Sunlight and warmth encourage algae and bacterial growth, a common problem found in containers of water. The best place is one that’s in a cool place without too much sunlight.

As I mentioned at the beginning of this post, don’t place your oil diffuser in direct sunlight such as near a window. Sunlight and warmth create a great breeding ground for the build up & growth of nasties such as algae and bacteria.

You definitely don’t want that!

Keeping it clean

Depending upon your water supply you may need to clean out your diffuser’s water tank occasionally. To do so, clean the water tank with a mixture of white vinegar and water using a soft cloth to wash the inside surfaces.

Don’t use detergent to clean it.

I get really good results using white vinegar (recommended by manufacturers) to clean not only my humidifiers but my aromatherapy diffuser too.

Will a diffuser keep you awake at night?

Clip art image of man sleeping in bedroom with essential oil diffuser

When it’s time for bed, sometimes it’s best to have your diffuser placed a bit further away from your bed. Although they won’t harm anything nearby (aside from wood surfaces I mentioned earlier), it’s better to put them where the vapor mist and aroma are distributed better. Also, some diffusers make a very small amount of noise. If you’re a very light sleeper (like me) that might be enough to wake you up.

Heavy sleepers aren’t going to have problems waking up when using their essential oil diffuser overnight. However, if you’re a light sleeper like I am it’s possible the occasional very slight bubbling and “gurgling” sound some make might interrupt your rest.

For example, my personal bedroom aromatherapy diffuser has a distinct electric motor sound I can hear if it’s too close. Additionally, there’s a very slight bubbling effect I can hear.

Those noises are typical for smaller units but aren’t only found in small models. In fact, it really depends on the brand and design – some make similar noises on a bigger scale just like humidifiers do.

Generally speaking, though, most essential oil diffusers have a whisper-quiet operation and aren’t very likely to disturb your sleep.

My advice is to go ahead and place yours a few feet from your bed just to avoid issues.

What are essential oils?

Diagram showing examples of essential oils used in diffusers

Essential oils are used in small machines powered by electricity to offer aromatherapy benefits. In other words, they release scented oils into a room by producing a super-fine water vapor containing the oil molecules. Essential oils are derived from the liquid form provided by many plants and fruits found in nature. A natural, scented pure oil is extracted and placed in small containers for diffuser use.

Essential oils are concentrated liquids taken from plants, fruits, and herbs found in nature. They’re extracted from a variety of herbs & plants with known benefits such as eucalyptus, lavender, orange, lime, cinnamon, myrrh, and many more.

The liquid is extracted by a process called distillation. The result is a product that’s able to easily evaporate at room temperature (also called hydrophobic).

Why are they called “essential” oils?

They’re called “essential” because they keep then natural essence (the natural properties and scent) of the plant they’re derived from. Unlike other oils you may have used before, they usually can evaporate without leaving a residue or oil behind.

Also, unlike many products you by they’re not simulated using chemicals or synthetic derivatives. They’re about as close as you can get to having the real plant source in your own room!

In most cases, we buy essential oils for aromatherapy in small vials made of glass or plastic. These oils are very efficient at making scents in a room. Normally only a few drops are needed each time.

While they’re not as cheap as some chemical-based scents you can buy, in reality, they’re a really good deal! That’s because when you break down the cost vs the amount of use you get they’re still a good value.

How does an essential oil diffuser work?

Illustrated diagram of how essential oil aromatherapy diffuser works

Shown: A diagram showing how an essential oil diffuser works. Diffusers are a type of cool mist humidifier as they convert water stored in the holding tank into a fine water vapor that’s released into the air. By adding a few drops of oil to the water, the oil mixes with it and when released as water vapor it fills the room with a pleasant scent of your choice. Most sold today use an ultrasonic electronic device to convert water into vapor.

Essential oil diffusers work by using electricity to power a water vaporizer (also called a nebulizer) and turn water into a fine mist.

The mist rises into the air and carries evaporated essential oil with it.

Diffusers are a different type of cool mist humidifier as they work on the same principle: they turn water into a super-fine mist that rises into the air and fills a room. They’re different, however, in their features, style, mist production, and water capacity.

In fact, they’re so similar that some cool mist humidifiers include an essential oil tray as an option.

Image of cool mist humidifier essential oil tray example

Shown: As they work the same as diffusers, some cool mist humidifiers include an essential oil tray feature. Shown is the popular Everlasting Comfort large room humidifier which includes this neat little option.

Cool mist humidifiers vs essential oil diffusers

There are a few differences between the two, however. Here are a few to know:

  • Diffusers are available with a smaller water capacity and are more ideal for smaller rooms. Humidifiers often come with a much later water tank.
  • Essential oil diffusers are more likely to be offered with decorative features like LED night lights or accent lighting. Some also have a more stylish outward appearance (Unlike humidifiers which are more practical in design)
  • Cool mist humidifiers often offer an adjustable mist output. Many standard essential oil diffusers do not, or offer 1 to 3 fixed output level options.

How to use essential oils with a diffuser

Image showing how to add drops of essential oil to a diffuser

Diffusers are really easy to use & keep up! That’s one reason I’m such a big fan of them. Add oils by carefully placing a few drops (usually around 2-3 or so) into the water reservoir after filling it. The cover is then placed over it before turning the unit on. Once it starts working you should smell the scent very quickly.

The great thing about them (and one reason I recommend them to many people) is that they’re really easy to use and maintain.

To prepare an essential oil diffuser, water is poured into the diffuser’s cup or tank then a few drops (about 2-3 drops typically) of aromatherapy (essential) oil are added.

Since most oils are concentrated it doesn’t take much. They’re very efficient at adding a noticeable scent throughout a room.

Getting your diffuser started is simple

After filling it with the recommended amount of water and adding essential oil the cover is placed over the top. The unit is then turned on and the diffuser begins working immediately.

Water moves through the nebulizer quickly and rises inside the cover, escaping silently through a small vent. At the same time, the water supply is agitated a bit to help mix the oil with the water.

As it runs the result is a very fine mist that resembles the look of smoke. However, it’s just a harmless, cool water mist with a wonderful scent added.

Summary – Key points to remember

Diffuser placement summary

Just a quick recap: Here are the main rules of thumb you can remember for knowing where to place your essential oil diffuser:

  • Keep them out of direct sunlight such as near a window
  • A good idea is to place them several feet from your bed or where you sleep (use 3 feet or more as a rule)
  • It’s recommended to put them 2 feet or higher above the floor
  • Keep away from furniture or other items that are affected by water (or place on a tray or cover the surface)
  • Don’t use diffusers on the carpet; If using on a floor, place on a tray or protective cover. Keep them where they won’t get knocked over
  • For convenience, be sure to keep them where they won’t get knocked over but are easy to reach for refills and use

What are essential oils?

Essential oil diffusers are small machines powered by electricity that offer aromatherapy benefits. That means they release scented oils called “essential oils” into a room. They’re great for many purposes including relaxation, better sleep, focus, and providing a healthy way to relieve stress.

Essential oils are concentrated liquids taken (normally) from plants. They’re extracted from a variety of plants such as eucalyptus, orange, lime, cinnamon, myrrh, and many more.

The liquid is extracted by a process called distillation that makes a product that’s able to easily evaporate at normal temperatures (also called hydrophobic).

Is a diffuser good for you?

Image of an essential oil diffuser on table near bedroom

Diffusers offer a safe, healthy alternative to other ways of adding aromas to a room. There aren’t any health risks involved in using them.

Unlike incense or oil warmers, there’s no danger of a fire hazard, hot ashes, or inhaling smoke. Additionally, while candles are generally safe they can be knocked over by accident, causing a possible burn or fire hazard with the hot wax or flame.

The health benefits of using a diffuser

While essential oils can be used on your skin for a range of reasons, there’s a risk of having an allergic reaction. That’s not the case with essential oil use.

It’s thought that inhaling the aromas from the oils stimulates certain areas of the brain that play a role in memories, behaviors, emotions, sense of smell, and thoughts. However, there’s no real scientific proof of any true healing abilities.

For the most part, natural (essential) oils offer some aromatic therapy benefits that candles, incense, wax warmers, and reed oil diffusers do but with much easier maintenance, lower cost per use, and more safety.

Essential oil health benefits and other uses

Quality oils can help with a number of everyday life and health problems:

  • Stress, anxiety, and depression
  • Headaches and migraines
  • Sleep and insomnia issues
  • Reducing inflammation
  • Sickness & germ fighting: Antibiotic and antimicrobial
  • Happier, fresher home or office environment
  • Mosquito repellant

Additionally, high-quality and properly prepared oils don’t use synthetic chemicals or other substances that are potentially a health hazard over time. That’s in contrast to others like incense sticks which burn other substances that you’ll inhale unknowingly.

Personally, I’ve suffered from headaches triggered by someone using incense and I was exposed to too much of the smoke over time. Unlike those, I can easily control how much (or how little) aroma I have in the air when using a diffuser.

How diffusers are good for skin

Image of dry hand skin cracking due to dry air

Severely dry air leads to a lot of uncomfortable symptoms including skin problems. Dry, painful cracking can occur and even lead to bleeding! The great news is that diffusers act like small humidifiers and can give some nice benefits you might not know about.

As I mentioned earlier, diffusers are a smaller type of cool mist humidifier. Because they release extra moisture into the air, humidifiers and diffusers provide a number of bonus benefits.

  • The added moisture helps with dry skin symptoms
  • Reduces allergens in the air, causing fewer skin irritants to be around
  • Help reduce scratching the skin for you, your pets, and children

Additionally, they help with dry noise conditions and nosebleeds as well as dry eyes. After running in a room for a long time the humidity increases to a more comfortable level.

They’re beneficial in both warm climates and during winter where the air is severely dry.

What makes a good oil diffuser for large rooms?

Image showing tips for what makes a good diffuser for large rooms

Buying a diffuser for a larger room (as opposed to a smaller room like a bedroom or office) isn’t going to be difficult if you know what to look for. There are a few things you’ll want to know first, however, before shopping.

My main suggestion for getting the right diffuser for a large room is one with a larger water capacity. This is because they’re able to run longer and since a medium or large room has more air volume it takes more time for the aroma to cover it completely.

Note: Diffusers are often made overseas where the metric system is used. Because of this, water capacity is often listed in milliliters (mL). 

They’re also often listed in 100s of mL (100mL, 500mL, and so on).

 

URPOWER small room essential oil diffuser example image

Example of a small room diffuser with a capacity of about 100mL. While it’s good for your bedroom, office, and other areas, the capacity is a bit small for larger rooms.

For example, my most recent purchase is the popular URPower color-changing diffuser for small rooms. At 100mL capacity, it’s fine for my bedroom but not for large rooms like a living room.

In that case, you’d want one with a water holder or tank several times that size. 500mL or larger is a good choice.

Features to look for

Larger capacity isn’t the only thing you should shop for. A good diffuser will also have nice features to make using it easier as well as for accenting your home, too.

Here are a few examples:

  • Adjustable mist level output (not required but very helpful)
  • Accent lighting features
  • Timer options for setting the run time
  • Easy to use
  • Easy to refill the water supply
  • Remote control option
  • Great buyer reviews, in general

Generally speaking, nearly all oil diffusers are very quiet if they’re well-designed. In fact, they’re so quiet they’re nearly impossible to hear in my experience.

Additionally, you’ll want to shop for one with many happy buyer reviews as people don’t like hassle or problems. A well-selling, highly rated diffuser is pretty much a sure bet.

I could talk about the features for a long time, but despite the nice things it offers it’s still really easy to use. Maintenance is a snap, and I’m sure you’ll agree too when you get one of your own.

To get it ready for use, just a few steps are needed:

  • Remove the top cover
  • Fill water to the top (note: there’s a nice little water filler cup provided)
  • Add a few drops of oil
  • Turn it on

Pick from 7 lovely colors with either a steady-on or color changing mode. Need a comforting night light? Just adjust the brightness as that’s a built-in feature, too. It’s a really nice looking design I love and I’m sure you’ll enjoy it as well. Great for both adults and children.

Wonderful lighting options

You’ll get some lovely lighting that’s a great addition to any room – and it makes a great night light, too! What I really like about the PureSpa XL is that the light feature works separately from the diffuser function.

Switch on the LED feature and the PureSpa XL begins gracefully and slowly moving through 7 lovely colors. You can choose to stay with 1 of the available 7 colors, too.

Easy maintenance, too!

Maintenance is easy and it’s a breeze in my opinion. Just remove the water tank & turn it upside down. Fill with clean water from your faucet and then add your desired essential oils.

Place it back on the base and you’re done! You’ll be enjoying great humidifier and/or essential oil therapy in seconds.

What’s truly amazing is how you’ll enjoy an unheard of 50 hours of run time on the low mist setting and a huge 22 hours on high. The competition simply can’t match that, even for more expensive models.

And unlike humidifiers from the competition with an essential oil feature, there’s no tiny, annoying tray which doesn’t work as well as adding the oil directly into the tank. It’s a real diffuser, not a gimmick!

I do wish there were adjustable mist dial and timer functions, but it’s a great diffuser that works really well and looks great anywhere. Honestly, you’ll be hard-pressed to find a better diffuser if you want a super-long run time and ease of use.

PROS:
  • Amazing 50 & 22 hours on water refill
  • Attractive design
  • Hold 2L (0.5 gal.) of water
  • Lighting feature work without diffuser running

  • Great 5 year warranty

  • Easy maintenance
  • Steady color option for lighting

  • No timer feature
  • No adjustable mist dial (only 2 settings)
  • Alternate color not available
  • Beeping controls might not be for everyone
  • Costs ~ 2x smaller units
  • Removing water tank may lead to some dripping

Reviews are fantastic, just like my opinion of it. Honestly, I’m impressed. For an aromatherapy diffuser that’s so affordable ($60 or less, if you’re lucky) it’s excellent.

It works great, looks great, and well…it made my room smell great!

That means hours of hands-off, hassle-free aroma. Not only that, despite its big large room performance and features it’s still wonderfully easy to use.

Speaking of features, check out some of the excellent ones you’ll get for a great price:

  • 7 accent light options great for mood setting or a night light
  • 360 degree rotating mist output nozzle
  • Precise adjustable rotating mist level output knob
  • Whisper-quiet operation – so quiet it’s nearly silent!
  • Great 325 to 450 square feet coverage
  • Not only a diffuser but true humidifier performance as well
  • Incredibly easy to use & keep up – takes only seconds
  • Auto-shutoff when water runs out

In fact, despite being both a humidifier and diffuser, it’s a cut above other models. Instead of a tiny oil tray on the side like others offer, you can add water and your favorite essential oils right at the top.

Maintenance & ease of use

It’s a snap to refill and get going again – it’s one of the easiest I’ve seen yet.

Maintenance is a snap! Just remove the top cover, fill it with water, and add a few drops of wonderful aromatic oil. Switch it on and enjoy aromatic air!

Not only is it powerful and really long-lasting, but you won’t have to worry about annoying maintenance like with some competitor’s models.

Maintenance is a breeze! Just 4 simple steps:

  • Remove the top cover
  • Fill with water
  • Add your aromatherapy oil
  • Replace the cover & turn on. Adjust output as desired

That’s it! You’ll be enjoying that wonderful scent you love in seconds.

The convenient rotating nozzle lets you point the mist output in any direction you like. It’s a great feature I find smart and well-designed.

Want to check the remaining water level? No problem! You can easily see the water through a small window right on the front.

No need to worry about what happens when the tank is empty as the diffuser shuts off automatically.

Cool accent lighting features

One thing that really sets it apart, in my opinion, is the great accent lighting feature. Pushing the LED light button lets you easily switch between one of 7 soft-glowing colors.

It’s a great way to add a pleasant touch to your room. Use the built-in dimmer and it makes a great night light, too!

Final thoughts

As great as it is, like any other product, Exqline large room humidifier isn’t perfect. I do wish there was an auto-off timer feature with selectable hours. Also, there’s no way to use a remote control with it, but that’s not something I really missed when using it.

PROS:
  • One of the largest capacities around
  • Over 22 hours use on low mist setting
  • Up to 450 sq. ft. coverage
  • Whisper-quiet operation
  • Adjustable mist output with dial
  • Super-easy operation
  • Great LED lighting feature with dimmer
  • Auto-off when the tank is empty
  • Visible water level gauge
  • 360 degree rotating nozzle
  • Maintenance is fast and simple
  • Great as both humidifier AND diffuser
CONS:
  • Decent but brief instructions
  • No timer features
  • No additional color options

If you like simplicity, long run time, and practicality that’s affordable, it’s an excellent choice. In fact the adjustable mist level is something I really love about it – few offer that!

It works fast, looks great, and is easy to refill and get working quickly.

4. URPOWER 1000mL With Remote – An excellent large room diffuser for everyone!

The URPOWER 1000mL has many of the same features their popular other models do. However, not only do you get a long run time on one tank (up to a generous 20 hours) a remote is included too!

What’s especially appealing to me about it is the price: it’s very affordable (under $35 if you shop smart). It’s also one of the most popular today.

It’s a very good value because of the great features you’ll get:

  • Remote control with buttons for all features (includes battery)
  • 1000mL (~ 1/4 gal.) water tank for long run time
  • High or low mist output settings
  • LED soft-glow accent lighting with solid-on or color changing options
  • Night light option when the diffuser isn’t in use
  • Auto-off upon water empty condition
  • Timer function: 3, 6, or 9 hour settings
  • Long run time: up to 15 hours in high mode/23 in low
  • Easy maintenance – refilling is quick and painless

Controls & use

Diagram of URPOWER round 1000mL diffuser controls and remoteControls are straightforward easy to use, both on the remote and front panel. Push each button to change the mist level, lighting mode, and steady-on or timer functions. Although I’m unsure why they’re using a rather generic remote that says “HDMI switch” on top.

The pushbutton controls are simple and work well. Just either the remote or front panel, just push the mist button to select one of the 2 provide output levels (high, low). Turn on the LED color changing or solid-on modes with the LED button.

What’s pretty cool about the URPOWER diffuser is the timer feature – I really like it! Using this button you’re able to choose from 3 auto-off timers: 3, 6, or 9 hours. Really handy for overnight use or when you want hands-off, worry-free operation!

Maintenance is easy!

Much like the other nice products from the company, it takes only seconds to refill the unit:

  • Remove the top cover
  • Fill with water (1000mL, ~1/4 gal.)
  • Add essential oil droplets

You’re ready to go!

URPOWER 1000mL diffuser LED colors image

The URPOWER diffuser provides several neat accent lighting options: Off, color-changing, or steady-on with your choice of 1 of 7 lovely colors. Additionally, unlike some competitors, you can use it as a night light as the lighting works the diffuser is off. Nice!

Want a nice mood light, accent lighting, or even a night light? You’re covered there, too.

Choose from one of the built-in LED accent lighting modes:

  • Off
  • Gradual (slow) color changing – 7 colors
  • Steady on (your choice of color)

What I like especially is that unlike others I’ve tested, you’re not stuck using the lighting only when the diffuser is running. Since the LED lighting works separately when you’re not running the diffuser it makes a great night light, too.

While I do have a few complaints (the odd printing on top of the remote, basic instructions are decent but not great, and the buttons could be labeled a bit better) it’s a great one and I’m sure you’ll say the same, too.

PROS:
  • 1000mL (1/4 gal) capacity
  • 15-23 hour run time on one refill
  • Up to 430 sq. ft. coverage
  • Works as a small humidifier
  • High or low mist output
  • Remote control works well
  • 3, 6, and 8 hour timer feature
  • Super-quiet operation
  • LED color accent light (changing or steady)
  • Lighting works separately from the diffuser
  • Nice, stylish shape looks good
  • Easy to use controls
  • Auto-off water feature
CONS:
  • Odd remote control label
  • Basic instructions could be better
  • Would prefer slightly different button labels
  • No wood grain accents like other URPOWER model
  • Doesn’t include essential oils

It’s a cool-looking, easy to use, and well-designed little unit that’s made even more convenient thanks to the remote.

It’s just a tiny bit more generic looking than some more expensive units, but I like it. For ease of use and great room-filling aromatherapy, it’s a great choice.

Head over now and find out why it's one of the most popular diffusers at Amazon.
