Features to Look for When Buying Essential Oil Diffuser for Large Space

  • Types of Diffusers
    There are nebulizers, ultrasonic/ humidifying diffusers, heat diffusers and evaporative diffusers. Ultrasonic/ the humidifying diffusers are the most common diffusers.

  • Diffuser’s Capacity
    How much moisture will the diffuser put out hourly? Given the large size of the room, will you have to refill it twice during the night?

    None of us likes waking up in the middle of the night. Therefore, whether the diffuser runs continuously or intermittently, it should last through the night or day.

  • Water Capacity
    A large water capacity translates into a high run time. This is because you’ll not have to refill it frequently.

    It is important to keep in mind that a large water capacity means a diffuser that will take up more space.

  • Noise Levels
    Most of us buy diffusers for stress relief through aromatherapy. It, therefore, beats the purpose having a diffuser with a loud motor.

    Even though the diffuser for a large room needs a powerful motor, it shouldn’t be loud. Therefore, look out for the quietest diffusers.

  • Auto Power Shutoff
    With all the stuff that runs through our minds all day and night, we are likely to forget about the water levels running low on an essential oils diffuser.

    To prevent the possibility of a fire, the oil diffuser can shut off automatically when the water levels run low.

  • Dimensions
    You need to consider the space the diffuser takes up even if you are looking for a diffuser for a large space.

  • Maximum Run Time
    What is the diffuser’s maximum run time and how much mist will go into the air within that time?

    A long run time may mean less refilling, but it also means that there is little moisture in the air.

What Are the Differences Between Humidifiers & Diffusers

Humidifiers increase the amount of moisture in the air within the room covered. They are ideal for cold and dry climates. They prevent sinus congestion, dry skin, flu and colds.

Diffusers produce micro-fine particles of mist which facilitate the delivery of essential oil’s healing prowess. The diffusers improve breathing, purify the air, and in aromatherapy, they improve sleep and relieve stress.


An essential oils diffuser creates an ambient and a calming space thanks to the stress-bursting effects of essential oils. The reduction of stress improves sleep quality.

The oils get into the body where they enhance breathing and the functioning of the immune system. The diffuser also moisturizes dry and chaffed skin.

Make sure to look for those oil diffuser that works quietly, and it also looks good. It releases moisture that has water and essential oils, and with enough power, the mist covers a large area.
