Best Essential Oil Diffuser for Large Rooms – Buyer’s Guide
Before we get to my reviews of the top six best essential oil diffusers, I’m going to outline a short buying guide. This will tell you everything you need to know about the best essential oil diffusers for large rooms.
How to Choose the Best Essential Oil Diffuser for a Large Room
When it comes to picking out the best essential oil diffuser for a larger space, there are a few important considerations you want to keep in mind. They’ll help you choose the best diffuser for your space, and they include:
Each essential oil diffuser will usually have an approximate square footage they’ll cover. You can get your own room’s square footage by measuring the length and width and multiplying them together. Match it to your essential oil diffuser and get one that has a larger coverage area.
Do you plan to sleep with your diffuser in your room? Maybe noises distract you. Either way, factor in the noise level. Larger diffusers have bigger motors. This leads to more noise when they run.
Larger essential oil diffusers can run anywhere from six hours up to 18 hours. They usually come with a continuous run time and hour marks so you can choose how long you’d like it to go for.
You want your essential oil diffuser to be safe when your kids or pets are around. Look for a diffuser with an automatic shut-off option, a stable build, and a secure reservoir. This will help it to stay upright and not fall over.
Benefits of Having an Essential Oil Diffuser for a Large Room
One of the main benefits of having an essential oil diffuser for a large room is that they can typically run longer than smaller diffusers. This is great when I want to set them in my kid’s rooms to run for a few hours overnight. I can set it and know it’ll shut off when the allotted time is up.
A second benefit is that you can use your essential oil diffuser in both larger and smaller rooms. You do have to be careful with your settings though because it can get strong if you run it for a few hours with a door shut and it’s a smaller room. You get the flexibility of using it in different size rooms without worrying about coverage issues.
The Best Way to Use an Essential Oil Diffuser in a Large Room
You want to start by finding a spot in your room that isn’t going to be in the way. If you have kids and pets like I do, this means putting it slightly out of the way by a wall on a sturdy table.
Add your water and add a few drops of your essential oil. It will dissipate the longer your diffuser runs, so you do want to keep this in mind. You can set a timer and let it run, or you can let it run continuously for a few hours. You should notice the scent start out stronger and slowly taper off.
The scent will spread throughout your room. If you don’t notice the scent as much, you can always add a few more drops of essential oil. Let it run, breathe it in, and feel it start to relax you. Just remember to clean it at least once a week to keep it running in top shape.
