This list of best essential oil diffusers for large spaces includes a carefully curated mix of ultrasonic and nebulizing diffusers from premium essential oil brands.
When diffusing oils in spacious rooms, you must use essential oil diffusers for large spaces so you can enjoy the aroma in every corner of the room.
Using a small diffuser in a large room will not give you the effects of the oil you are diffusing. That’s because small-sized diffusers do not have the output necessary to diffuse the scent throughout the large area. You may get the aroma while standing close to the device, but that scent will get fainter as you move further away from the device. And it will be completely unnoticeable when you’re at the other end of the room.
When diffusing oils in large rooms such as a spacious living room or bedroom, what you need are essential oil diffusers for large rooms.
Remember, it’s not the capacity of the unit that matters. A unit with a larger water capacity is not necessarily the best diffuser for large rooms. What’s more important is the output of the device.
The best essential oil diffuser for large rooms is one that has a larger coverage area. You can see the coverage area of each of the large-space diffusers listed below. The best one for you will depend on the size of your room.
Plant Therapy TerraFuse™ Deluxe Diffuser
Modern, stylish, and powerful, Plant Therapy’s TerraFuse Deluxe Diffuser is a top-rated essential oil diffuser for large spaces.
The TerraFuse Deluxe Diffuser features a large water reservoir with a 210ml water capacity, which easily covers an approximate area of 430 square feet. It operates using ultrasound technology, which requires no heat or chemicals allowing the essential oils to retain their chemical profile so you get the full therapeutic benefits.
Five timer settings with continuous and intermittent options give you complete control over the amount of essential oils diffused into the air and the run time of the diffuser. When used in continuous mode, the diffuser will give you up to 8 hours of diffusion
The device will shut off automatically when the timer is complete or the water has run out. That’s another huge plus point as it means you don’t have to worry about keeping track. Just switch it on and do your thing while the device runs in the background.
Made of polypropylene and measuring 5.25” in height x 6” in width, the Terrafuse Deluxe Diffuser comes in two earthy colors – brown and cream – that add a natural touch to any room.
