If you are in a hurry and just want to find out what the best essential oil diffuser for Large Rooms is, then we recommend the URPOWER 1000ml Essential Oil Diffuser as the best one.

Using an essential oil diffuser is a great way to take advantage of adding fragrance to your home while having a session of aromatherapy. There are countless diffusers on the market today but not every diffuser fits into every room. There are certain diffusers that are better for larger rooms than others.

While some diffusers are great for your décor because of how they’re constructed and decorated, you want to be careful with purchasing a diffuser because you want to make sure it’s going to be effective in the room you place it. If you’re looking to place a diffuser in a large room, like a living room or basement, your options are more limited than if you were to put a diffuser in a smaller room, like your bedroom or bathroom.

In this post, I’ll discuss why using a diffuser is a great way to add fragrance to your home and what you should look for in a diffuser. Then I’ll review the best diffusers for large spaces before choosing one that is the best out of the list I’ve compiled.

6. SpaRoom Theralizer Nebulizer Essential Oil Diffuser

A nebulizing essential oil diffuser, SpaRoom Theralizer employs the Bernoulli principle to diffuse oils into the air. Basically, pressurized air is forced into the reservoir with oil, which causes the essential oil to atomize into microparticles.

Those particles are then emitted out of the reservoir into the environment. This process requires no water. SpaRoom Theralizer isn’t merely an oil diffuser. With its beautiful wooden design, it may be able to greatly complement your interior.

As far as oil diffusion goes, this device is designed to create a potent stream of oil particles directed into the room. This diffuser runs for only 2 hours per full cycle (with 2-minute on and 1-minute off cycles), but it delivers a strong aromatizing effect in this short time frame.

Pros:

  • Beautiful design.
  • Up to 1000 square feet coverage.
  • Potent nebulizing effect.

Cons:

  • Slight tendency to clogging.
  • Fragile: the internal reservoir is made of glass.
  • Always unavailable

What to Look for in an Essential Oil Diffuser

When deciding what essential oil diffuser is best for you and your home, you’ll want to make sure that it has features that are going to fit your life and preferences. There are countless different diffusers on the market, but not every single one is going to have the same features as the rest. Before purchasing a diffuser, you’re going to want to look around and see what diffuser is going to fit your lifestyle.

How Large an Area Is Covered?

One of the first things that you’ll want to consider when buying a great diffuser is the coverage area it offers. Some diffusers are meant for large spaces while others are not. This is easy to determine, however, because it is always listed on the package by the manufacturer. Generally, the larger the diffuser, the longer it will last because it can hold more water in the first place, meaning that you won’t have to refill it quite as often.

If you’re planning to use a diffuser in a large room such as your living room or den, it’s best to do two things: buy a larger diffuser that is made for bigger rooms and make sure that you put enough essential oil in it to cover the entire room and last for a while.

Ease of Operation

Another consideration when buying the right essential oil diffuser is the ease of using it. With most diffusers, you simply plug it in and press the “on” button but others can be a bit more complicated. Again, if you read the directions on the packaging and pay attention to the photograph that’s on there, you can easily determine the difficulty level of operating the unit.

In addition, some of the more sophisticated diffusers have various settings that allow you to choose how many hours you want it to run. Most diffusers will list their maximum operating time on the package and this can range from as little as 18 hours to as long as 40 hours. Many diffusers also simply run until they run out of water and then the unit is shut off automatically.

The Noise Level Is a Consideration

Each diffuser has a different noise level even though most of them are extremely quiet. Let’s face it; they are likely going to be used to help you relax. Most of the noise comes from the steam or mist that is spewed out once you turn the unit on but if you look for a unit that specifically mentions on the package that it is quiet, you’ll be in good shape because this is what you want.

The noise level is especially important when you’re planning to put the diffuser in a bedroom because no one can sleep with too much noise in the room. However, even putting it in the living room or bathroom means that you should look for one that is quiet because it is more convenient and nicer to have around.

Timer

One feature that’s incredibly handy for someone with a busy schedule is a built in timer. By having a built in timer, you don’t have to worry about forgetting to turn off your diffuser. Many products with timers come with different time increments, such as one hour, three hours, and six hours. There are also many that have a steady setting that allows you to decide when you want to turn it off, if it’s longer than six hours.

Auto Shut Off

Another feature that you should keep an eye out for is an automatic shut off feature. This feature will turn your device off when it runs out of water. This will prevent your diffuser from being a fire risk or from becoming ruined due to being run without water.

Build-In Lights

There are also diffusers that come with built in lights that are great to use as a nightlight or just to provide some ambiance to whatever room you place it in. This is great for people who like to use candles partly for the light they give off. While you don’t get the same effect as you would with a candle flame, you are given a nice ambiance from the light. Some lights also give off different colors, too.

Work as a humidifier

Some essential oils also double as a humidifier too. If your home gets dry during the winter months, you’re going to definitely benefit from having a humidifying diffuser in your home. Not only will your home smell amazing, but you’ll be adding moisture into the air too. This can help prevent your skin from drying and prevent bloody noses that come from dry air.

Which Diffuser is Really Worth Your Time?

While all of these products are great and will fit perfectly in any home, there is one that stands out from the rest. The URPOWER 1,000 milliliter aromatherapy essential oil diffuser is without a doubt the best of the best. From the strength of the fragrance throw to the different features that this product is equipped with, you’re going to have the best experience with this product.

One of the best features this product offers is the remote control that it comes with. You can control the timer, light, and power of this device. The remote is an incredibly handy tool that is a real game changer with the diffuser.

Final Thoughts

Using an essential oil diffuser is a great way to safely add fragrance to your home. Each of the five diffusers I reviewed are great to use in your home but the URPOWER diffuser definitely takes the cake and is really worth your time. No matter which diffuser you choose, your home will smell amazing and feel great.

I love candles! I have personally tried over 100 brands of candles. The total burn time of these candles is over 5000 hours. I also talk about essential oil diffusers and reed diffusers. Essential oil diffusers and diffusers are also an important part of the scent in my home.
