Diffusing essential oils around your office, bedroom, or even car is a fantastic idea. In this article we will discuss the Best Essential Oil Diffuser for Large Spaces in your home or office.

So, what should you do if you want to distribute the beneficial aromas of essential oils across a wide space, such as a living room or an office? Some folks have problems getting complete coverage with their current essential oil diffuser to all areas of a large open floor plan at home or at work.

We’ll explore how to get the most out of your essential oil diffuser and enjoy the advantages of diffusing regardless of the size of the room you’re in, as well as the best essential oil diffuser for large space areas.

bamboo-and-glass-Essential-oils-air-diffuserDispelling a Myth about Essential Oil Diffusers

One of the most popular misconceptions regarding essential oil diffusers is that a diffuser with a bigger capacity will cover a larger area.

The quantity of space a diffuser’s mist can cover has very little to do with its capacity. When determining how long the diffuser can run, the capacity is more significant. However, the strength and general quality of the essential oil diffuser determine the coverage area to a large extent.

Perhaps the misperception stems from the fact that higher capacity essential oil diffusers often produce a heavier mist. Actually the point is that capacity has little to do with how much area a certain essential oil diffuser can cover.

Making Use of Multiple Diffusers in Large Spaces

If you’re aiming to cover an area of 800 to 1,000 square feet, buying and making use of two diffusers is your best bet. Despite what some firms claim, there isn’t an essential oil diffuser that can cover that much ground on its own.

It’s better to use two of the same oil diffusers for consistency. This ensures you’ll have the same strength, capacity, and appearance for both.

They should not be placed in corners or against walls, since the center of the room will not be covered. Instead, set each one approximately a third of the way into the room, if feasible in the middle. You’ll receive the most coverage from both units this way, without creating cloying pockets of scent in odd parts of the room.

Try Increasing the Amount of Essential Oil Diffused

While everyone has their own preferences, most oil diffusers function best with 3-6 drops of your chosen essential oil or oil blend per 100 ML of water. More oil means a more potent scent and hence increased coverage when diffusing in a big area. But don’t go crazy—if you generally use 3 drops per 100 ML, try increasing it to 5 or 6 and evaluate how it works in the furthest corners of the room.

You can play with the amount of oil you use (as long as you don’t go overboard). Because all essential oils are slightly different, some trial and error may be required until you find the ideal amount for your essential oil diffuser.

One word of caution here, however, for pet parents. You do need to be very careful when diffusing essential oils around them, as we’ve explained here and here, and increasing the volume of oil in the air in this way may not be safe for them.

Use Higher Quality Essential Oils

Remember that the quality of the essential oil you choose can make a big difference in how much pleasure you have diffusing, whether you’re diffusing in a big room or a small one.

Higher-quality oils are more potent, so you’ll get a lot more bang for your buck even if they cost a little more than “budget” oils. It could be because of the oil you’re using that you’re having problems achieving coverage up to the maximum area of your diffuser.
