3 Best Essential Oil Diffusers for Large Room


1. The Square Aromatherapy Essential Oil Diffuser


As you already know this diffuser is our first pick for this review article. It is a colorful and modern ultrasonic diffuser with a 700ml capacity. This diffuser can run for up to 20 hours on a low mist setting and 10 with high mist. It measures 6.5 x 6.3 x 5.7 inches and weighs 1.8 lbs so is easily transported.



  • Large capacity of 700ml
  • 20+ hours in low mist run time
  • Extremely quiet
  • Auto Shut-Off function
  • 7 colors soothing LED light


  • Water drains a bit faster in high mist mode

The simple square shape fits into any home and it has a relaxing LED light. There are two options for brightness and it can be set to gently work through its seven color options or stay in one shade. This diffuser has a lovely glow and the option to set it at one color means it can fit into any environment. With its gentle light, it can also double as a nightlight when used in a child’s room. It also functions as a humidifier to create the optimal conditions for health.

The refill cup for this device is a bit small but this is easily fixed by simply using your own cup to refill the water. It doesn’t need to be refilled very often because of the large tank so this isn’t much of an issue. The Square Aromatherapy Diffuser also has a range of time settings, with 1 hour, 3 hour or 6 hour running times so it can be set to quickly freshen up the room or gently mist all night.


2. The Housemile Large Essential Oil Diffuser


It has a 600ml tank and an interesting spherical shape. The unique globe design and dark wood style of this device are elegant and understated. This device measures 7.5 x 7.5 x 8.3 inches and is an incredibly lightweight 1.2lbs.



  • Direction control facility
  • Light alert for empty tank
  • Elegant design with wood grain surface

  • Large size




This diffuser allows you to fully control the direction of the mist by rotating the top cover, a great feature for those who like especially potent essential oils. A light alerts the user when the tank is empty, meaning it won’t disturb precious sleep. A combination of diffuser and humidifier, this model has a decently sized tank with an auto-off sensor.

The Housemile Diffuser runs for up to 8 hours which is enough for the average night’s sleep but may not quite cover a full night for everyone.


3. The Apalus Glass Ultrasonic Diffuser


Apalus Ultrasonic Aromatherapy Essential Oil Diffuser is a quiet and sophisticated glass diffuser with color-changing lights. At 3lbs, this device is the heaviest of the three diffusers with a 500ml tank meaning it also has the smallest capacity. The range of color choices for the light makes full use of this diffuser’s glass cover and it suits any mood.



  • Around 18 hours run time
  • Auto Shut-Off function
  • 7 colors changing lights


  • Compared to other two slightly low capacity of 500ml


The Apalus has a great range of choices for timing, with options for 1 hour, 3 hours, 6 hour or continuous mist. The continuous setting has a running time of about 18 hours which is more than enough for overnight use. While this item also works as a humidifier the smaller tank means that the mist itself is a bit lighter than the other two models reviewed.


Our Recommended Choice

All of the above options are a combination of diffuser and humidifier, which is really the best way to fully enjoy the benefits of essential oils while ensuring restfulness in an ideal climate. The Square Aromatherapy Essential Oil Diffuser is a clear winner because of its large tank capacity which means that there’s no fussing about in the middle of the night and your sleep will not be interrupted by an empty tank. This is true even on the high mist setting as it can operate for 10 hours without any assistance from you.The choice of light and color options make it a great fit for any home or business and its square shape ensures this diffuser will fit into any environment.

A good night’s rest is truly priceless and the Square Diffuser is the best way to guarantee total relaxation. It can also run for 20 hours on the low mist mode, making it ideal for businesses such as massage therapists and yoga studios where a constant soothing aura is desired.


What is a Diffuser?

An Essential Oil Diffuser is a convenient device that helps to relieve stress. A diffuser is a machine that uses vapor to fill the air with a mist scented with the essential oil of your choice. A diffuser freshens the air and fills the space with tranquillity. They are highly customisable and portable devices and come in many shapes and sizes.




Many people use diffusers as a path to better health – essential oils are beneficial for respiratory and skin conditions and can aid mental health by relieving stress. Diffusing essential oils throughout your home can help with mental focus, repel insects and pests, and even ward off colds.


Diffusers vs Humidifiers

A diffuser disperses essential oils through the air. A humidifier, meanwhile, disperses water vapor to fill the air with moisture. This is convenient in dry climates so that the best humidity level can be maintained in order to avoid problems caused by dry air such as skin irritation or breathing problems. Diffusers are often stand-alone items but it is also possible to have one item that combines both functions. If you care about the air quality in your home, it makes sense to use a diffuser that also humidifies.

The Different Types of Essential Oil Diffusers

There are four different types of essential oil diffuser – nebulizing, ultrasonic, heat and evaporative. Nebulizers simply emit a constant spray directly from the essential oil bottle itself, the result is concentrated and strong. Ultrasonic diffusers combine the oils with water for a finer mist they also function as humidifiers. Evaporative diffusers use a fan and a pad or filter. The essential oil is added to the filter and circulated by fanning it through the air. The heat diffuser is similar to this but disperses the oil using heat rather than directly fanning it.

Evaporative and heat diffusers don’t really enable the user to get the most from essential oils, as heat can change the properties of some oils and soaking a filter with oil means that the flow is not constant – the lighter parts of the oil are dispersed first while the more beneficial layers are not propelled in the air until the end. Nebulizers and evaporative diffusers are more beneficial, with nebulizers being more expensive and a bit noisier. Evaporative diffusers are suited to a wider range of functions and have the same benefits as nebulizers while getting more use out of the essential oil because the dispersal is more subdued.

Of course, there’s also a wide choice of capacities. This is why it’s important to choose a diffuser capable of misting an entire room – if you have a large home there’s no point in purchasing a tiny diffuser that would barely make a difference to the corner of your living room.


Essential oil diffuser benefits

Essential oil diffusers are great for relieving stress and setting a calming atmosphere. This can be anything from a relaxing vibe for your morning yoga session, a romantic scent for date night, or something calming to help send you off to sleep. It’s also an incredibly useful item for covering up scents left by pets as it acts as an air freshener without any of the unpleasantness of artificial aerosols.
