What’s the Best Essential Oil Diffuser for Large Space?

If you want to learn more about these devices, keep on reading below. However, I wanted to quickly introduce a few essential oil diffusers for large spaces that I think are the best in the market.

What Is an Essential Oil Diffuser?

An essential oil diffuser is basically a device that evaporates oils, and diffuses their scent into the surrounding environment (source). The essential oil molecules are distributed through the air. You then can inhale the vapor into your lungs and let the molecules work their magic. All of that can be done with a few drops of an essential oil.

Types of Essential Oil Diffusers

There are four main types, and you should probably now about them.

Ultrasonic or Humidifying

  • check
    Electronic frequencies generate ultrasonic waves that break down water and essential oil molecules to form a fine mist.
  • check
    Need to be cleaned often because of the contact with plastic.
  • check
    Adds moisture even though the efficacy of diffusion is diluted.

Nebulizing

  • check
    Works on the system of pressure and vacuum controlling oil and air, similar to a perfume atomiser.
  • check
    Does not require heat or water.
  • check
    Diffusers are made of wood and glass.

Heat

  • check
    Requires heat for evaporation and diffusion.
  • check
    May change chemical composition if the temperatures are too high.
  • check
    Least expensive from the diffusers available.

Evaporative

  • check
    A fan blows the air through a filter on which the essential oil is dabbed. The blowing wind increases the rate of evaporation.
  • check
    Less expensive but it leads to uneven diffusion that’s caused by difference in volatility of various essential oils.

VicTsing 300ml Cool Humidifier Ultrasonic Diffuser

My Rating

Can I just begin by pointing out how CUTE this humidifier looks? Seriously, its vibrant colors with the woodgrain patterns are enough to energise you. I won’t lie, I purchased this humidifier the moment I saw it just because it looked so appealing. It was just an adorable new accessory that I have placed in my room! Anyway, the looks aren’t everything. It has a volume of 300 ml, which makes it suitable for large rooms. You can also switch between the high and low settings depending on your room size. It generates about 30ml of mist per hour. In terms of run-time, this humidifier is a beast as it can work for around 10 hours without needing to refill it. Additionally, you can choose between 4 different time settings: 1 hour, 3 hours, 6 hours and steady on.

Since this humidifier makes use of ultrasonic technology, it’s not just quiet but also produces smooth and ultra-fine mist. It keeps my skin fresh and moisturized even in winters. Additionally, it’s helped me with my insomnia quite a bit as I usually use it in night time. I’m glad it shuts off immediately after the device runs out of water.  The humidifier has cool LED lights that can change their colors (there is 7 of them). I use mine as a night light by my bedside. If you’re not a fan of the lights, you can always turn it off. The only main problem is the singular switch that controls everything from the mist to the light. It might take some time getting used to. Other than that, the fact that this humidifier is made of plastic also worries me somehow. Apart from that, it works very well.

URPOWER 500ml Diffuser Humidifier

Quality

Price

My Rating

URPOWER essential oil diffuser and humidifier come in two sizes: the 500ml one and the 1000ml one. It’s a three-in-one device that can act as a diffuser, humidifier, and can also be used as a night light. It also uses ultrasonic diffusing technology. Because of its large capacity, it can be used in a large space. Using the ‘Mist’ button, you can program the diffuser to run for 60, 120, 180 minutes or steadily on until it auto-shuts down. That usually happens when it runs out of water. It can last for up to 10 hours. Additionally, you can control the intensity of the spray. Since this diffuser holds a greater amount of water, it naturally produces a stronger mist too. However, the device needs to be cleaned more often than the other devices. In fact, you should probably do it every day. 

The diffuser also has a 7 LED color display that switches seamlessly from color to color. If you are looking for a diffuser/night light for your little one, this could work well. The lights can be used even without turning the diffusion on. Therefore, it has a clear edge over VicTsing model. Although, you should probably know that lights cannot automatically shut down. Another advantage is definitely the capacity, and, therefore, the device humidifies the room quite well. This is an ultimate win-win for the entire family. Just be careful and keep the lower vents open while using it. Blocking the vents will lead to strain on the motor and, subsequently, the device might underperform. The instructions aren’t well translated, which might be problematic. However, the device is pretty easy to use, so you should be fine.

InnoGear Upgraded 150ml Ultrasonic Diffuser

My Rating

If you’re looking for an essential oil diffuser that is more compact and portable, then this one might be just the thing for you. It has a smaller capacity of 150ml so you shouldn’t plan on using it in a very large setup! Should be enough for a large room though. What I personally like about this diffuser is that it has two modes of spraying. The intermittent mode: it emits mist for 30 seconds and shuts down for the same amount of time. For the steady mode, as the name suggests: the diffuser stays on before it shuts down. Both the modes allow the diffuser to run for 9 to 11 and 7 to 9 hours respectively. Additionally, you can use it in a light-only mode. It has the same auto shut-off function when out of water. However, it doesn't have a timer.

Compared to the other diffusers, it has a relatively easy interface since the modes are color coded. However, it lacks an on/off switch, which basically means that you’ve got to yank the power cord out of the socket to turn it off. Even the LED lights could not get any brighter than they are in this diffuser. They are like homing signals meant for aliens!!! If you are one of those who like to have a dark room while sleeping, you might want to consider another diffuser from this list. Although, if you are on a tight budget, it’s a decent purchase.

My Rating

This is yet another attractive diffuser (maybe woodgrain makes everything look better!). It’s effective even over the 200-500 square feet area. If you’re looking for something that’s a humidifier and a diffuser at the same time, then that’s not exactly what you want to buy. The company honestly states that it’s essentially just a diffuser and can only provide slight moisture. Like all ultrasonic diffusers, this one hardly makes any noise. In fact, the slight noise it has could very much help with your sleep! Unlike the InnoGear Portable Diffuser, this has soft lights, which can otherwise be turned off if not in use. Although, the colors keep switching rather quickly so it may make you more anxious than relaxed. Also, the button for switching colors can be a tiny bit hard to press. However, that’s nothing major.

As the name suggests, it’s a long-lasting diffuser that can run for 10 to 12 hours. It looks great and the dark bamboo may actually complement your furniture. However, the chiselled appearance has a downside - trying to open the lid can sometimes become a problem. Another issue with this diffuser is that the high and low settings have no distinctive feeling. Not having a timer puts it at quite a disadvantage because then you just have to wait for the water to run out or actually go and manually turn it off. A valuable accessory that comes along with this diffuser is the measuring cup, which ensures that you don’t overfill it. An overall, the diffuser does its job and looks great.

InnoGear Real Bamboo Ultrasonic Diffuser

My Rating

This diffuser is crafted from real bamboo indeed! If you like something that is easy on the eyes and minimalistic, then you should definitely consider the device. It looks so good you might even think it belongs in a spa. If you’re conscious about using plastic, then this natural and environmental friendly diffuser would be a much better pick. Additionally, it’s more durable than its plastic counterparts. You’ll also find a measuring cup in the box that will allow you to fill up the diffuser easily. It comes with a booklet that contains a few essential oil recipes. That’s definitely a nice touch from their side. Unlike all the other beeping models above, this one just quietly auto shuts down without any annoying noises. Thus, you can enjoy your uninterrupted sleep. It has a capacity of around 130ml and a long power cord.

The diffuser has 4 modes are: Continuous Mist, Intermittent (10 seconds on, 10 seconds off) Mist, 1 Hour Mist Timer, and 2 Hours Mist Timer. Therefore, it combines the best of all the modes mentioned above! Additionally, the they are color coded as yellow, red, blue, and green respectively. Once you get the hang of it, you can easily determine the mode it’s operating on by simply checking the color. Moreover, the diffuser can run for 16 hours on intermittent mode! If I ever have to purchase another diffuser to own or to gift, I would probably buy this one.

Difference Between a Diffuser and a Humidifier

You’re probably wondering how an essential oil diffuser is any different from a humidifier. Are they the same? No. Here’s why:

  • The primary role of a humidifier is to introduce humidity into the air. Also, humidifiers generally have a larger water holding capacity. Diffusers, on the other hand, can hold smaller amount of water.
  • An essential oil diffuser can be more cost-effective if your primary requirement is to evaporate the essential oils.
  • Diffusers simply aromatise the area and have a cooling effect. Humidifiers, on the other hand, warm up the room.
