What Size Diffuser Do I Need For A Large Room ?

Before choosing the right essential oil diffuser, it is important to understand what is the meaning of a large space. 

So,what does a large space even mean when it comes to diffusers?

The definition of a large space means an unoccupied area or room. 

Alternatively, large spaces could also mean spacious. And spacious is described as a living quarter that has plenty of room.

However, the first thing that comes to mind when thinking of a large area is open living rooms, master bedrooms, vaulted kitchens, offices, and a combination room.

These areas are normally the biggest area of the home.

Because of that, if the large space is bigger than 1000 sq ft. Then the area might require you to place two aromatherapy diffusers in the room.

This way, two diffusers will reach both ends of the room.

Not only, will the diffuser give the room more coverage. But the mist and aroma will be stronger.

However, if the room is less than 1,000 feet you should be fine with one diffuser.

Choosing the Best Essential Oil Diffuser For Large Spaces

When it comes to diffusers for large areas, they are not all made.

Size and type are two main factors to consider when choosing the best oil diffuser for a large area. 

Below, I’ll be breaking down these factors for you.

These two components are both important when considering a diffuser.


All types of diffusers will distribute essential oil aroma into the air, but each one works differently.

Below you will find a description of the different types of aromatherapy diffusers. and the square feet each one covers.

Types of diffusers and how much square feet they cover:

  • Nebulizer diffusers- 400-1000 sq
  • Evaporative- 100 square feet
  • Ultrasonic (Top Rated) 400-1000
  • Heat such as candles 250 sq

Nebulizer diffusers-

This type of glass aromatherapy is perfect for large spaces.

In fact, an nebulizer diffusers does not use heat or water to distribute the essential oils.

In other words, it is waterless.

This means you get to breath the pure essential oil aromas.And Since the essential oils are kept in pure form unlike other type of diffuser.

The pure essentil oils allows you to receive all the benefits.

Evaporative fan diffusers –

Rely on a fan to circulate the aroma. This type doesn’t cover much square footage.

The biggest downside is the noise.

Along with this, the essential oils evaporating quickly.

Ultrasonic diffusers-

When it comes, to diffuser types the most popular pick among essential oil enthusiasts is the ultrasonic.

Not only, do they distribute aroma evenly. But they also work as a humidifier.

Unlike the nebulizing diffuser, the ultrasonic uses water.

Another advantage of the ultrasonic diffuser is that they require less maintenance than other types. And are efficient for big areas.

This is Because of the large reservoir tank.

Heat diffusers-

Obviously this type uses heat.

One bad point is that it is used for small spaces like bathrooms.

So in other words, they do not work well for large space.

In fact, essential oil diffusers that use heat can be  dangerous.

This is because they can easily knocked over by children and pets. Thus, causing fires.

Additionally, heat diffusers such as candles are inefficient when it comes to receiving the benefits of essential oils.

This is because they heat up the essential oils. Which causes loss of aromatherapy benefits.

With all the diffusers mention above.The type of diffuser you choose for a large room is based on preference.

But an ultrasonic is the most versatile. And the most popular choice for room coverage.


Diffuser size is also important for larger rooms, but not a dealbreaker.

Larger tanks will run longer and require less filling.

One thing, to keep in mind is that you can adjust the strength of aroma by changing the oil ratio in the diffuser.

Other factors to consider include:

  • Reservoir material: Some oils can degrade plastic
  • Various run modes: Intermittent or constant
  • Features: color changing lights, safety features
  • Large water chamber for longer use and less refilling

How Far Do Diffusers Reach?

There are several aspects to consider when figuring out how far diffusers reach. Capacity will play a role, but also the type of diffuser.

Ultrasonic diffusers with a larger tank are typically your best choice for reaching larger spaces.

And Also Nebulizer diffusers work just as well for reaching a large area. Smaller diffusers can work.

But will not, travel as far for open areas. But to improve a small diffuser you can adjust the running time or amount of oil. This will help maximize the scent and reach.

How Many Essential Oil Diffusers are Needed in a House?

An essential oil diffuser typically only covers one room in a house, so the rule of thumb is one diffuser per room.

How Long Do Essential Oil Diffusers Last?

There’s no clear answer on how long your essential oil diffuser will last. Its lifespan depends on how often you use it. It also depends on the quality of your diffuser and if you care for it properly.


One of the great things about essential oil diffusers is that you don’t need too many accessories to use them.

Aside from a power adaptor, some useful accessories include distilled water, vinegar, and some soft brushes for cleaning.

While most tap water is suitable, many expert oil users recommend using distilled water. Essential oil diffusers should be cleaned regularly and the cleaning supplies you need are inexpensive.

Rubbing alcohol or vinegar and a cotton swab or a soft brush is all you need.

A bonus accessory that you might want to consider is an essential oil organizer.

Not only does an oil rack keep things organized but it’s a fun way to display.

Here is a link to the essential oil organizer that I use.

Plus it’s a popular choice and it is highly reviewed. Essential organizer See On Amazon
