Best Essential Oil Diffusers for Large Space: 100ML, with Night Light, Wood Oil & Adjustable Mist Mode Humidifier

Aromatherapy is basically creating a relaxing environment using nice smelling oils.

It can help you relax after work and can also be a great way to help the people working in your office a little more easily.

Aromatherapy might sound fancy, but really the only thing you will need while you are doing it is an essential oil diffuser.

This is a little machine that evaporates water with the oil in it. This helps the smell spread out evenly and across a wide area.

Oil diffusers are a niche item, so finding the right one can be tough. Here is a list of some of the best to help you decide.

1. InnoGear 500ml Aromatherapy Essential Oil Diffuser

InnoGear 500ml Aromatherapy Essential Oil Diffuser


  • Releases thick mist
  • 500ml capacity
  • Battery supports 15 hour run time
  • Ultrasonic technology

What We Liked

Battery life: Aromatherapy is not a short term thing. You would want to leave your diffuser on for a while. This product has excellent battery life. A full charge means that you can keep diffusing aroma into your room for a solid fifteen hours. You can leave it on at night when you sleep, wake up to a beautiful smelling room and leave it on while you are at work as well. This helps you come home to a good smelling house!

Works quietly: A noisy diffuser is counterproductive. Aromatherapy is supposed to be relaxing. This diffuser uses ultrasonic technology. This helps it run quietly. Once you turn it on, you wouldn’t even realize that it’s functioning if it didn’t release such a pleasing fragrance.

Wide coverage area: This diffuser is meant for large spaces. It can cover nearly three hundred square feet. This makes it for offices and other large, open spaces. You can leave the diffuser on in the corner and it will quietly get the job done on its own.

Fragrance spreads rapidly: Not only does this diffuser work in large areas, it gets the job done quickly too. The mist it release is quite thick. This means it doesn’t take long to spread to every corner. The thickness of the mist also helps the fragrance last longer.

Timer settings: The auto shutdown feature helps make this product better. It ensures that the smell never gets overpowering. The fifteen hour run time is tempting, but that much scent can give you a headache. This is a useful feature that can help prevent that from happening.

What We Didn’t Like

Requires a lot of cleaning: This is a high quality product, which means it requires some maintenance. It probably won’t last very long if you don’t clean it very regularly. This can be annoying because it becomes one extra thing you have to handle every few days.

2. Aromatherapy Essential Oil Diffuser

Aromatherapy Essential Oil Diffuser


  • Glass design
  • LED lights
  • Free of toxic substances
  • 100 ml capacity

What We Liked

Automatic shutdown: This diffuser has a capacity of one hundred milliliters. The water levels can become dangerously low rather quickly, especially if you are using the diffuser in a big room. Low water levels can damage your diffuser. This product comes with an automatic shutdown feature which helps prevent such damage from occurring.

Safe to use: A lot of diffusers are made with materials that might leach toxic chemicals into the essential oil. While these chemicals won’t cause any immediate harm, they can cause respiratory problems and allergic reactions. This product is free of such toxic chemicals which is a great benefit.

Pretty lights: The aromatherapy will relax you, but this diffuser’s LED lights will really complete the package. The lights display up to seven colors, and the combinations can be quite hypnotic. We enjoyed using this product to wind down, and the lights were a big part of our enjoyment. The automatic patterns can often get distracting, but the lights are easy to shut down if this is the case.

Attractive design: This product is made of glass, unlike the InnoGear Aromatherapy Oil Diffuser which is made of wood. Both materials have their own perks, but glass often looks more informal unlike the classy feel of wood. This gives this product its own unique charm in more relaxed social settings.

What We Didn’t Like

Low liquid capacity: A hundred milliliters isn’t going to last very long if you are trying to diffuse the essential oils in a large room. You will have to frequently refill this diffuser if you want it to keep running. This can be a bit of a hassle, especially when you compare it to the InnoGear diffuser which has five times the capacity.

3. COSVII 120ML Glass Oil Diffuser

COS VII 120ML Glass Oil Diffuser


  • Two modes
  • Perfume bottle design
  • 120ml capacity
  • Anti-dry protect system

What We Liked

Different modes for different occasions: You can use this diffuser continuously or intermittently based on what mode you prefer. Continuous would work better for things like large office spaces. The intermittent mode might be better suited to smaller spaces like bedrooms or bathrooms.

Diverse functionality: This product doesn’t just work as an aromatherapy oil diffuser. It also works as a humidifier. It can be used during dry months to keep the air feeling comfortable which can be good for your skin. You can also use this oil diffuser as a nightlight thanks to the LED lights it comes with. This can be useful for parents with kids that are scared of the dark.

Slightly higher capacity: If the Aromatherapy Essential Oil Diffuser’s low volume was a deal breaker for you, you would like this product’s slightly higher capacity. 20ml does not sound like a lot, but it can help you refill this diffuser a lot less often.

No cleaning required: While you might want to clean this product up for its look, there is no cleaning required for functional reasons. This product will continue to work perfectly well whether you clean it or not.

What We Didn’t Like

Prone to breaking: This aromatherapy oil diffuser is made of glass. While this looks quite pretty, it can be a nuisance because glass tends to break easily. Kids can knock this diffuser off a shelf, it might fall while someone is carrying it. There are a lot of ways in which this diffuser could break.

Mist too thin: A thick mist isn’t always preferable, but it is useful in a lot of situations. This oil diffuser only gives out a thin mist which is why it was bumped down to third place.

4. Essential Oil Diffuser

Essential Oil Diffuser


  • Works as a humidifier and diffuser
  • Multicolored LED lights
  • 300ml capacity

What We Liked

Excellent capacity: This product offers more than twice the capacity of the COSVII diffuser and three times the capacity of the Aromatherapy Essential Oil Diffuser. This is enough capacity to let you keep the diffuser on for hours every day for multiple days without worrying about refilling.

Stylish design: Unlike the previous two entries on this list, the Essential Oil Diffuser is made of wood. This gives it a sleek appearance that is both modern and simple. It also has a few traditional design elements because of how the wood is lacquered.

Pleasant water sound: The water tends to bubble while the mist is being diffused. This is quite a pleasant sound because the diffuser is otherwise quiet.

What We Didn’t Like

Annoying power light: Whether this diffuser is on or off the power button will be lit up. The only way to turn this light off is to unplug the diffuser. This can be annoying for people that need darkness to sleep. It also makes it impossible to use this product for all night aromatherapy while you’re asleep.

5. YHW Cool Mist Humidifiers

YHW Cool Mist Humidifiers


  • Facilitates 6-12 hours of uninterrupted use
  • Mood lighting
  • Eco friendly

What We Liked

Works well in dry weather: Dry weather can be very inconvenient. Your lips get chapped, your eyes feel weird and overall you can get quite uncomfortable. This diffuser is primarily a humidifier, so it is understandable that it helps make dry rooms more comfortable.

Interesting lighting: One thing that sets this diffuser apart from others is the way it lights up. A lot of diffusers out there have great lighting, but the LEDs mostly light up randomly. This diffuser lights up according to a specific mood.

Good for the environment: We definitely appreciate how environmentally friendly this diffuser is. It has been made with safe products that don’t leach any chemicals.

What We Didn’t Like

Paint tends to peel: This product looks good initially, but the paint quickly starts to peel off. This might explain the lower than average price of this product. Once the paint starts to peel off this product stops looking nice.

Weak diffusion: This product’s mist stream doesn’t diffuse very quickly. It can take a long time to reach all of the corners of a large room. However, if you use it in a small, personal office it will work fine.

6. Diffusers for Essential Oil 2 Pack

Diffusers for Essential Oil 2 Pack


  • Wood grain design
  • 450ml capacity
  • 8 LED lights

What We Liked

Superb capacity: This diffuser’s capacity is almost as high as the InnoGear diffuser at the top of this list. That really is saying something! It’s enough to continue aromatherapy for several days straight.

Attractive design: This product comes with a wood grain design. This is quite attractive looking and fits into Eastern yet modern design styles.

Compact and portable: This diffuser ships at 2.6 pounds. That is a very low weight. This makes it easy for you to travel with this product on you. You can take it with you while you commute!

What We Didn’t Like

Poor infusion: This product does not infuse the oil with the water well enough. A large area will get the mist, but the fragrance won’t spread out strongly enough. Fragrance is this product’s primary purpose so this might be a deal breaker.

Bright light: This product faces the same problem as the Essential Oil Diffuser at number 4. It has a bright LED light in the front that might disturb you while you sleep. Hence, this is another product that won’t work for night time aromatherapy.

7. PowerLead Tdif PLH004 100ml Aroma Essential Oil Diffuser

PowerLead Tdif PLH004 100ml Aroma Essential Oil Diffuser


  • LED lights
  • Weighs 9.6 ounces
  • Air purification feature

What We Liked

Gives off great fragrance: This product will diffuse a lot of fragrance in the room it is placed in. It will also spread the fragrance quite far away from itself.

Extremely lightweight: Weighing in at only 9.6 ounces, this is one of the lightest oil diffusers on the market. It is also quite small so it is easy to fit into your bag. You can take this diffuser along with you and start aromatherapy wherever you are!

LED lights are calming: The aromatherapy is boosted by the calming lights this product has. These lights have very beautiful shades and you can pick which shade you go with in your aromatherapy session.

What We Didn’t Like

Looks and feels cheap: This product is made of some pretty low grade plastic. While this doesn’t affect how well it diffuses aroma, it does give the product less value for money.

Lights can be boring: The LED lights in this product are static so you will have to see them one at a time. This can get boring. Most oil diffusers tend to have more dynamic lights that alternate between colors.

How to Buy Essential Oil Diffusers for Large Space?

Aromatherapy is a time-tested technique to relax your mind and calm down your senses. Traditionally, it was carried out by burning oils over charcoal or a candle. In the present day, it is done with the help of oil diffusers. These appliances make the diffusing of fragrance easy and effective as compared to traditional methods. They come in various sizes, shapes and their power to spread the oil fragrance in large or small spaces.

They use water mixed with oil to do the diffusing. It ensures that the scent is spread evenly across the large space. Oil diffusers come in different sizes, shapes, quantities, battery timings, LED lights and motor capacity.

A right and appropriate type of oil diffuser can be very beneficial for improving your mood and relaxing you.

We want you to make the best possible decision about oil diffusers, and this is why we have developed a buying guide to take you through it.

This buying guide will not only explain which type of oil diffuser is best for you, but it will also answer your questions relating to using it safely, the best place to keep it and how you can clean it.

Which technology is best?

Based on the technology, oil diffusers can be divided into three types

  • Ultrasonic – these devices use electric current to spread the oil in the shape of the mist in the area. Electric current is provided by the rechargeable batteries.
  • Evaporative – they use a fan to blow air into the pads containing drops of essential oils. They can spread the fragrance rapidly in the room but you may lose the therapeutic advantage with them.
  • Heat diffusers – oil diffusers that make use of the burning candle are called heat diffusers. They may come cheap but are slow and can take a lot of time to clean.

Ultrasonic essential oil diffusers are the best as they provide you with a constant supply of fragrance. The oil does not get hated in them and it retains its properties. The mist they produce is cool and helps in creating an aromatherapy environment.

How much capacity should a good oil diffuser for large space have?

Oil diffusers with 500 ml capacity work the best. They can really save you from the hassle of filling the oil again when placed in a large area. However, oil diffusers with capacities of more than 400 m can also work fine.

What is the ideal battery timing?

Oil diffusers that have a battery timing of more than 12 hours are great options to be placed in large areas.

Which is the most durable oil diffuser?

Oil diffusers made of wood usually go a long way with you. Many people are of the view that they do not add aesthetic value to the places where they are placed. This is not true; some of the diffusers in our list are made of wood, are really durable and look great. Diffusers made of glass can look pretty and charming, but they are prone to breaking.

What is the benefit of having lights on the diffusers?

LED lights can help in adding charm with the aroma in the place. Colors can help you wind down after a long day. There are diffusers with multiple lights; you can select the one that you like the most. Some diffusers come with bright lights; they can be disturbing to some people.

Which is the best place to keep the oil diffuser?

It really depends on the capability of your diffuser to spread out the scent. If you have a powerful diffuser, you can keep it in a corner and it will do its work. If your diffuser takes a lot of time in spreading the scent throughout the large space, you can place it on the center table.

What are the precautions while using oil diffusers?

Essential oil diffusers should be avoided near the eyes, mouth, nose or skin. If you are allergic to inhaling a certain smell for longer periods, then you should not use the oil diffusers. People with asthma should also avoid oils with strong smells as they can cause problems for them.

If you are suffering from a cough, flu or any such disease, please consult your doctor before using oil diffusers. Pregnant mothers, post-surgery people, newborns should not be exposed to oil diffusers.

Can oil diffusers be harmful to pets?

Pets like birds, cats, and dogs can be allergic to the oil you are using in the diffuser. You can always make sure that your pet remains healthy after you put in new oil by seeing that it does not develop an allergy to the smell and stays comfortable with you. You can do some research online about the oil and its impacts on your pet.

Please avoid keeping the oil diffuser very near to aquariums as the oils can form a thick layer over water and can cause the supply of oxygen to reduce for the fish.

What is the impact on nearby plants?

Essential oils have no harmful impacts on plants. You can use diffusers in gardens before setting up the table or while having some leisure time there.

How can you clean the oil diffusers?

Cleaning your diffuser on regular basis will ensure its proper working. Following method is the best method to clean your diffuser.

You require:

  • Dry clean and a soft cloth
  • White vinegar
  • Cotton swabs
  • Clean water

How to clean it – fill the diffuser halfway with clean water and add 8-10 drops of vinegar in the water. Turn on the diffuser for 5-10 minutes to disperse the mixture evenly. Empty out the diffuser and with the help of cotton swabs wipe out any oil marks. Wash the diffuser with clean water and dry it out with the help of the cloth.

What features can make my diffuser smarter?

Add-ons like a timer, auto-shut off, remote control, Bluetooth connectivity, and a clock can make your diffuser smarter and user-friendly. But these features usually increase the price tag of the diffuser and do not increase the working capacity of the diffuser.

Wrapping Up the Buying Guide

With the help of these simple devices, you can help yourself relax, improve mood and enjoy quality time with your family and friends. They can also help you in repelling insects and mosquitoes through the scent they disperse. Get one for yourself now and feel the difference.

Final Words

Aromatherapy does not have to be inaccessible. It can be quite easy to attain if you pick the right diffuser. The list above only has the best, and there is a wide variety to choose from as well.

One thing you will notice is that none of the products are overly expensive.

Even the most expensive one is relatively affordable, and if you really want something cheap a couple dozen dollars will do the trick. Still, we suggest you go for our top pick the InnoGear Oil Diffuser.
