Best Essential Oil Diffuser For A Large Space

One of the best ways to make the most of the health benefits from essential oils is to use a home oil diffuser. Not only will an essential oil diffuser give your home an amazing and welcoming smell, but it will help to cleanse and purify the air in your home.  To get the best result you will need to use a essential oil diffuser for a large room as a standard one will not fill the air in your home enough. 

Choosing the best essential oil diffuser for a large space can be daunting. How do you know if you need a evaporative,ultrasonic, or heat diffuser? Or which model is going to suit your family home the best? To help we have put together this list of the best oil diffusers for a large room. 



Types of Oil Diffuser For Large Room


There are four main types of oil diffusers that are best for bigger spaces.

Evaporative Diffusers

These diffusers evaporate the oil and spread it around the room with a fan. You will normally have to drop your oil of choice onto a pad or filter.

Ultrasonic Diffusers

These diffusers tend to be super quiet as they spread the tiny oil micro-particles around a space as a mist using electronic frequency vibrations. This type of diffuser along with the Nebulizer gives off a concentrated aroma.


A nebulizer processes the essential oil into very small particles that are then released into the air.

Heat Diffusers

Like the Evaporative diffuser you will place oil on a pad or filter. Instead of a fan, the oil will be evaporated using heat.


What to Look For When Choosing The Best Essential Oil Diffuser For A Large Room


You have chosen what type of diffuser will work in the space you have. Now there are some other things you should look for to make sure you get the best home oil diffuser for you.

Motor Size

Work out of the motor size will disperse the oil throughout the space you want. Remember the Ultrasonic and Nebulizer diffusers have the quieter motors ( the Ultrasonic is the quietest of the two). So if you have a very large room and need a powerful motor, these may be your best option.


We all get busy and trying to remember another appliance to turn on and off is never easy. Safe yourself some time and invest in a diffuser that has a timer. There are so many different options that you will be sure to find one that suits your routine perfectly. We also love that this saves money as you wont leave your diffuser on for long hours and waste your precious essential oils.

Water Tank

Unless you plan on refilling the water tank on your diffuser constantly, make sure it is a large enough capacity for your room size. We suggest one from 300 to 500ml.
