Ultrasonic Diffusers produce high-frequency vibrations in the water to disperse the essential oils in a fine mist.

They are pretty quiet…I find the faint humming relaxing at night. During the day I doubt you’d hear it at all. These are great if you have dry air from air conditioning.

Nebulizer/ Atomizer Diffusers don’t require water as they turn the essential oils into an almost gas like state before releasing tiny particles of pure essential oils into the air.

They are the most effective method of preserving the therapeutic qualities of the essential oils. 

Fan Diffusers are a pretty basic method of diffusing. You drop your chosen oils onto a pad and a fan then disperses the oils around the room. Not ideal for large rooms as they only cover a small area.

Heat Diffusers warm the essential oil and force evaporation. While candle diffusers and other heat diffusers are cheap they have a few drawbacks.

Heat alters the chemical composition of the oil meaning that it may not retain its therapeutic properties . Heat diffusers also aren’t effective in large rooms as limited vapours are released.

Evaporation Diffuser allows the oils to be exposed to air where they evaporate naturally.

Pretty useless for filling a large room with fragrance but they look beautiful for personal use.

Nebulizer/ Atomizer and Ultrasonic Diffusers are the most effective essential oil diffusers for large rooms so our top picks below look at the best of these.

Ultrasonic Diffuser or Nebulizer Diffuser?

Nothing’s perfect right!? And there are pros and cons to both ultrasonic and nebulizer diffusers…

An ultrasonic diffuser is for you if you want to add humidity to the air because you live in a dry climate or have air con. You can even use them without oils as humidifiers.

They use less oil too as you add around 6 drops to the water (use less if infants are in the house…read this safety guide).

A nebulizer/ atomizer diffuser is for you if you want the full therapeutic benefits of your essential oils retained.

These are waterless diffuserswaterless diffusers so there’s no need to refill them and they won’t add moisture to your air if you live in a humid area.

Now let’s take a look at some of the features you’ll want your essential oil diffuser for large room to have.

What Features Does An Essential Oil Diffuser For Large Room Need?

• Power – you need it to be powerful enough to disperse vapours all around a large space.

• Large water tank – this allows for longer running time with less refilling. You’ll want one with a tank that’s at least 300ml.

• Timer –  to be honest a timer is great to have on a diffuser for any size room. It means that the diffuser will automatically stop diffusing after the selected time. Saves oils and energy and prevents too much fragrance being dispersed (especially useful if babies and infants are around).
