The Best Aromatherapy Diffuser for Large Rooms
“If you can’t smell it, then what’s the point in having it?”
Whilst you’re descending upon the natural world of aromatherapy, chances are that you’ve already discovered the most sought after ultrasonic diffuser technology. This clever device is the easiest way to disperse aromatic molecules into the air, the most effective way to reap the benefit of essential oils. Apart from that, this stylish appliance comes in different sized water tanks to accommodate any room size, with a wide range of modern designs to suit your décor and it all comes with an Affordable Price Tag!
How does the Ultrasonic Aroma Oil Diffuser work?
This popular device disperses essential oil vapour into the air. A tiny mechanical part will send high frequency vibrations into the water tank to break it up into micro-molecules, thus creating a cool mist/vapour.
Some things to keep in mind for a Large Room Diffuser
There are a some factors to think about, so it’s important to pay special attention to the device you intend to purchase. There are models designed for small to medium rooms, such as bedrooms or personal offices, but for anything larger you may need to consider the size of the room you want to use it in. Always look for the best diffuser designed for large rooms.
Each ultrasonic diffuser comes with its very own set of unique features, including light settings, power modes, and automatic shut-off. My recommendation for a large room would be to choose one with a water tank / reservoir size from at least 500ml upwards. This device will also include a powerful dispersion mechanism, lasting longer and operating much more efficiently for larger spaces.
If you’re thinking of purchasing one of the larger models, we’ve created a list of the best diffusers for large rooms.

What’s the difference between a Cool-Mist Vapour and a Warm-Air Vaporiser?
The distinction between the two is that the ultrasonic vapour is produced by vibrations of water to create a fine, cool mist, whereas a warm-air vaporiser involves heating the water, until it reaches boiling point to create a warm steam.
Both types serve the function of producing moisture into the air. When choosing a vaporiser, the benefits of each type must be weighed up against the other to determine which one will benefit your family the most.
Is “Safety” important to you?
The ultrasonic aroma diffuser is safe! It creates a cool mist and operates without a heating element, as opposed to a warm-air vaporiser. The warm-air vaporiser can pose a potential hazard for burns and can create a breeding ground for bacteria and mould, if there’s a lack of ventilation in the room .
What I also love about the ultrasonic model is that it has an extremely quiet motor, and it’s easy to forget that it’s even in the room.
