Best Essential Oil Diffusers for Large Spaces in 2020

Also known as aromatherapy, essential oil therapy is a medical treatment method involving pure aromatic essential oils. These oils are extracted from various parts of natural plants with curative properties, which are believed to boost health and mood. By relieving anxiety, reducing congestion, and inducing feelings of relaxation, essential oil therapy can also help with a lack of sleep.

Of the many aromatherapy techniques practiced by many homeowners, using essential oil diffusers is most enjoyable, convenient, and effective. Essential oil diffusers are devices that help disperse the therapeutic aroma of different essential oils throughout the air in a house.

Purchasing the right essential oil diffuser may significantly impact your aromatherapy experience, determining oil accessibility, potency, and more. Using essential oils in a large room can pose a great challenge. One common drawback is when the essential oil diffuser cannot spread the aroma across the whole room. Also, the lack of capacity to last for an extended period is another issue. 

With Dozens of different diffusers available out there, you will appreciate if you get a comprehensive guide to help you pick the best diffusers for large rooms. Luckily, you have found one. All of the essential oil diffusers available in this guide are designed specifically to use in large spaces. But before you can purchase any of them, read the following sections first to learn more about essential oil diffusers.

Cleaning Up Diffuser Capacity Misconceptions

Many individuals believe that essential oil diffusers with a larger capacity cover a large area. The capacity only indicates the amount of essential oil and water that a given diffuser can hold. And it has very little to do when it comes to the size of space that its mist can cover. 

Capacity is only essential when estimating the period that a diffuser can run. The mist will cover the area less or more determined by the quality and strength of a diffuser. Sometimes, essential Oil diffusers with larger capacities tend to offer stronger mist, so perhaps this is where the misconception originates. However, the truth is that capacity does not affect the area that a diffuser can cover.

Understanding this is important before you can purchase your diffuser, especially if you are looking to diffuse your favorite essential oils in a large space.

If Your Diffuser Has a “Heavy Mist” Setting, Use It!

Many diffusers that you will come across out there have strong/heavy mist settings. And if you are trying to find the maximum coverage that a diffuser can pump out, you will need to use it. However, you should be ready to use up your essential oil a bit quicker.  

This is the only side effect, but it will work excellently when you install it in the right place of your large room. It is always advisable to place the diffuser in your room’s center if possible to void cutting off its effective area.

Use Many Diffusers for Very Large Spaces

If you are trying to diffuse/cover a space anywhere between 800 and 1,000 square feet, you should have two diffusers. Currently, no diffuser is capable of covering such a space by itself. A sure bet here is to install several of them, but two are enough, and they should have the same strength, capacity, and look. You should install them strategically to cover the most area.

Do not install your diffusers near walls or corners since the center of your room will not be covered. Each one should cover at least half of the room, which means that they should be anywhere near the center. By doing so, you will get maximum coverage from the two diffusers, as long as they have the same blend.

Increase the Amount of Essential Oil in the Diffusers

In most cases, diffusers work excellently when adding between three and six drops of your essential oil in every 100 ml of water. If you are dealing with a large area, you will need to increase essential oil. More oil means strong concentration hence increased coverage. 

However, you should be sure not to add too many drops of essential oil. If you usually add a maximum of three drops per 100 ml of water, you should increase it to either five or six and see the size that it will cover. You should experiment with the amount and type of oil that you normally use as long as you are within the recommended range. All oils are not the same, so you will need to try out several of them before finding a perfect match and amount for your room. 

Use High-Quality Essential Oil When Diffusing Large Areas

When it comes to diffusing large rooms, the quality of an essential oil determines the area of coverage. High-quality oils tend to be strong, but they usually cost more than budget-friendly ones. 

If you have been having issues when trying to diffuse a large room, then the type of oil that you are using could be the main problem. So you should look for high-quality essential oils, and everything will be okay.
