The therapeutic benefits of essential oils are well known and using an essential oil diffuser in large spaces can be incredibly beneficial. An essential oil diffuser is a device that disperses the aromatic compounds of essential oils into the air, improving air quality and providing a calming atmosphere.

For those looking for an effective way to create a peaceful ambiance in their home or office, investing in a high-quality essential oil diffuser for larger spaces might be just what’s needed! In this blog post, we will explore the best options for an essential oil diffuser for large spaces.

When it comes to finding an essential oil diffuser for a large space, there are three main types to consider: ultrasonic, nebulizer and evaporative/fan diffusers. Ultrasonic diffusers use ultrasonic vibrations that break down the essential oils into tiny particles which are then dispersed into the air. Nebulizer diffusers use pressurized air to atomize essential oils into a fine mist which is then released into the air.

Finally, evaporative/fan diffusers release the aroma of essential oils through a pad or filter which lightly scents the room when air from the fan passes through it. Each type of essential oil diffuser has its own unique benefits and drawbacks, so it’s important to consider what is most important before making a purchase.

How We Choose


When choosing an essential oil diffuser for large spaces, size is an important factor to consider. If a larger space requires more coverage, then a larger model might be necessary. Additionally, features such as adjustable levels of mist output and lighting are also important factors that should influence your decision when selecting an essential oil diffuser for larger spaces. Finally, cost can also be a factor when searching for the perfect essential oil diffuser for your needs - just remember that investing in quality will ensure longevity and effectiveness over time.

Essential Oil Diffuser FAQ's

What size diffuser do I need for a large room?

It depends on the type of diffuser you are using. If you are using a nebulizing diffuser, then you will need a larger diffuser for a large room. If you are using an ultrasonic diffuser, then you can use a smaller one for a large room.

How much area does a diffuser cover?

On Average a diffuser will typically cover a 20-foot by 20-foot area.

Where should you not put an oil diffuser?

You should not put an oil diffuser in a room where there is a lot of moisture, such as a bathroom. This is because the diffuser will add more moisture to the air and could potentially cause mold or mildew to grow. You should also not put an oil diffuser in a room with children or pets, as they may inhale the essential oils and could potentially be harmed.

Where is the best place to put a diffuser in a room?

There are a few things to consider when deciding where to put a diffuser in a room. The first is the size of the room. If the room is large, you'll want to diffuse in more than one place. The second thing to consider is the airflow in the room. If there's a lot of air movement, it might be difficult to keep the scent in one area. Finally, think about what you want to achieve with the diffuser. If you're looking for mood enhancement, you might want to diffuse near where people are sitting or sleeping. if you're looking for relief from congestion or allergies, you might want to diffuse near the entrance of the room.

Should a diffuser be placed high or low?

It depends on the type of diffuser.

If you are using a nebulizing or ultrasonic diffuser, the answer is high. You want to suspend the essential oil droplets in the air so that people can breathe them in.

If you are using an evaporative or heat diffuser, the answer is low. The essential oil needs to come into direct contact with the heat source in order to vaporize.

Is a bigger diffuser better?

There is no definitive answer to this question since it depends on a variety of factors, such as the size of the room, the type of diffuser, and the essential oils being used. However, in general, a bigger diffuser is often better because it can cover a larger area and release more essential oils into the air. This can be especially beneficial if you're using oils that have strong aromas or are meant to be therapeutic.

How do you scent a large room?

Diffusing oils into the air is a popular and effective way to scent a large room. The most common type of diffuser disperses the oil into the air by using heat to create a fine mist. This mist then travels throughout the room, releasing the fragrance of the oil.

Some diffusers use cold water or ultrasound to disperse the oil, but these are less common. Some oils are better suited for cold-water diffusion than others, so you'll want to do some research before purchasing a diffuser. If you're not sure which oil to use, lavender is always a safe choice.

How do I know what size air diffuser I need?

There is no one-size-fits-all answer to this question, as the size of air diffuser you need depends on the size of your room and the type of humidifier you are using. However, here are some general guidelines to help you choose the right size air diffuser:

If your room is small (less than 100 square feet), then you should use a diffuser with a rating of 250 milliliters or less.

If your room is medium-sized (100-300 square feet), then you should use a diffuser with a rating of between 251 and 500 milliliters.

If your room is large (greater than 300 square feet), then you should use a diffuser with a rating of 501 milliliters or higher, which can easily cover a 20-foot by 20-foot area.

Regardless of the size of your room, you should also make sure that your diffuser has adjustable mist settings so that you can adjust the amount of essential oil being dispersed into the air. This will ensure that you don't overwhelm any guests or family members who are sensitive to strong smells.

Finally, it's important to keep in mind that some oils require more time to diffuse than others, so if you plan on using multiple oils at once, make sure to choose an appropriate size diffuser for each one.

What should I look for when buying an oil diffuser?

When looking to buy an oil diffuser, you'll want to consider the size of the diffuser, the type of material it is made out of, and the features it offers.

The size of the diffuser is important to consider because you'll want to make sure that it will fit comfortably in your home. The type of material it is made out of is also important because you'll want to make sure that it is durable and easy to clean. Finally, you'll want to look for a diffuser that offers a variety of features such as variable speed settings and automatic shut-off.

Bottom Line

When looking for the right oil diffuser for your home, it’s essential to consider a variety of factors such as size, material, and features. Additionally, all rooms are different sizes, so you will need to adjust the settings on the diffuser accordingly in order to get the most out of it. By investing in a quality essential oil diffuser that fits your needs, you can ensure that you get maximum performance and enjoy the therapeutic benefits of essential oils in your home.
