Best Diffuser For Large Room [2017 Comparison Table]

Oil diffusers allow you to add healthy oil molecules to the room, increasing moisture, adding fragrance, and offering you an abundance of health benefits. They can be used in any room, no matter the size.

Why you should Use an Oil Diffuser in a Large room:

Oil diffusers are safer than candles and don’t have the harmful chemicals that air fresheners tend to use. Fight unwanted and unnecessary odors in your home by adding natural, safe essential oils to the diffuser’s water. These scents can be calming, energizing, or a combination of both.

The molecules put out by these machines are perfectly safe to breathe in and can even help fight against flus and colds. Air freshener molecules, on the other hand, may contribute to breathing issues and sickness.

To select the right choice, first, think about how big the room is that you want to put it in. Options with larger tanks will work best and last longer in bigger rooms. Every diffuser has different shut-off settings, light options, and power modes.

Choosing the Right Diffuser

For larger rooms, the most appropriate oil diffuser will have a water tank that is bigger than average. This will allow the moisture to reach every corner of the room, spreading the oil’s fragrance effectively. While most of these products feature motors, some use reeds instead.

High ceilings, an open kitchen, or a spacious living room all call for the strength of a larger diffuser, but when you’re attempting to select the best oil diffuser for a large room, how are you to know which features to look for?

Based on the considerations above, the following are some of the best options on the market.

12-Month Warranty: This device comes with a full warranty for a full year, covering both typical wear and tear and possible manufacturing defects.

PROS

  • A Unique Look: The first feature that will stand out about this diffuser is its unique look, which includes a top made from frosted glass with flowers decorating it. Even when it isn’t in use, it looks great, but the lights make it look even prettier.

CONS

  • Only one Option for Light Settings: The ISELECTOR has a beautiful LED light system in it, but it only allows you to have it on constantly changing colors, rather than giving the option to have only one.
  • Will smell Strange without Enough oil: The product works great if you use enough oils in it, but if you don’t it may give out a strange smell.
  • Button Visibility: The buttons to switch settings on this diffuser are small and can be hard to see for some.

  • The Power Panel isn’t Lighted: Using the diffuser in the dark can be a challenge since there’s no LED panel on the settings for the device.
  • The On/Off Button: While using this oil diffuser, some may find that the power button may take a few tries before it responds.

4. Apalus 500ML Glass – Large Aromatherapy Diffuser

This oil diffuser offers three different therapies to users; light, aqua, and aroma. The process of water-oxygen diffusing adds negative ions to your room to cleanse your body and lift your mood, releasing you from the stresses of the day.

This diffuser’s transducer produces over 2 million vibrations every second, allowing the oils it emits to be absorbed safely and quickly by your lungs and skin. It comes with frosted, transparent glass and beautiful LED lights that show through, adding to your room’s ambiance.

  • Quiet: Even though the Apalus diffuser releases a lot of mist, it’s quiet enough to cause no disturbances while you work or take a nap.

CONS

  • The Power Cord: Although the diffuser is beautiful, some may find that the power cord takes away from its decorative quality.
  • Leaking Risks: This diffuser will leak if it isn’t reassembled perfectly, so make sure you’re careful with that when you use it.

  • Not completely Silent: Although it’s quiet, the device is not completely silent and may disturb light sleepers.

How to diffuse your Favorite Oils in a Larger Space:

The holding capacity of an oil diffuser has more to do with the length of time you want it to run, instead of the size of the room, it will work for.

Do you need a Big Diffuser?

Getting a large diffuser isn’t necessary for a large space unless you wish to use it for more than a few hours at once. For those who want to run their oil diffuser all day long, a 300-500 ml diffuser will be optimal. If you don't need a large diffuser, check out our top 10 essential oil diffuser comparison chart.

For Massive Areas, get Two Devices:

Regardless of what the oil diffuser company claims, the mist will only travel so far. If you’re working with 1000 square feet, it isn’t realistic to hope for the whole room to be covered in a strong mist with just one diffuser.

If you want to cover the whole area, you’re better off buying two identical products and running both at the same time.

Make sure you’re Using Enough Oil:

If you want a large room to be sufficiently covered, you can’t be too conservative with how much oil you use in the tank. As a rule of thumb, you can use between three and six drops for every 100 ml. For very large rooms, however, use as much as you see fit.

It’s hard to know what the exact size of your diffuser is. Oftentimes, the product information will state 300 ml for the reservoir capacity, but only holds 150 up to the maximum fill line. This is a commonly experienced result.

For a diffuser that states 300 ml, but really holds 150, you can use about 10 drops of essential oil. If your tank holds 500 ml of water, feel free to add up to 20 or more drops. Everyone has different preferences, so adding less or more to it is fine.

Don’t forget to be creative when you use oils, blending together different scents to create your ideal match. If you’re working with a limited budget and don’t want to use too many drops in your diffuser, use the less expensive oil for 20 drops, and use five of the more costly oil. If you’re on a budget, avoid expensive oils such as ylang ylang or rose.

Using the Diffuser’s Heavy Mist Setting:

A lot of diffusers allow you to choose between a light or heavy mist. In a bigger room, the heavy option will always work better for filling up the room with mist. When it doubt, check the product’s user manual to find out how to use this setting.

Use Quality Essential Oils:

If you aren’t using a quality essential oil, you will not end up with a strong aroma filling up a large room. Although it may seem economical at the time, you should avoid very cheap oils with added ingredients or chemicals. Do your research on different brands of essential oils to find the best companies for quality products.

The Best Choice

Using the tips given to you in this article, you should be able to find the oil diffuser that not only works well for a large space but perfectly fits in with your design style. Each diffuser recommended in this article come with rotating colors, a safe automated shut-off function, produce a thick mist, and help to humidify your room. Any of these choices will be a great one, so figure out which settings matter most to you and opt for a design that fits in with your unique style.

Conclusion:

If you want the best diffuser for your home’s large room, the Apalus 500ML Glass Ultrasonic Aromatherapy Essential Oil Diffuser is your best bet. It’s attractive, quiet, and holds a significant amount of water and oil.
