Using essential oils for their health benefits is one of the oldest and still most trusted methods of easing anxious minds and soothing ailing bodies. While essential oils can be consumed or applied to the skin, if you want to access the full potential of their healing properties it’s best to use a diffuser. It’s also a great way to purify and cleanse air, adding a fresh and inviting aroma to your home and workplace.
If you have a large room or office, some smaller diffusers simply won’t emit enough mist to effectively fill the space. A large aromatherapy diffuser will provide more mist, for a longer time and is the best diffuser for large room situations.
I’ve researched the best essential oil diffuser for large room coverage and compiled a list of my top five picks. There are new large room diffuser products appearing on the market (they seem to get bigger all the time) all the time, but at the time of writing, these are the top large diffusers.
This list was last updated September, 2018.
This is both a large room essential oil diffuser and a humidifier with the added benefit of an alternating colour night light.

Unlike many other diffusers, the URPOWER interior pops out for easy cleaning and its clearly marked water lines means you’ll avoid an overfill spill. Despite its large capacity and power, the diffuser is amazingly quiet and a great essential oil diffuser for a large room.
