5 Best Essential Oil Diffuser For Large Space

Aromatherapy balances natural fragrance with healing power. The tradition has been in use since the ancient times, and with each generation, the knowledge and popularity of homeopathic health grow. Picking your oils is half of the battle, but finding the best essential oil diffuser for large spaces can be troublesome unless you understand what to look for in an ultrasonic diffuser.

What Can A Large Room Diffuser Do?

Aromatherapy devices range from incense sticks or cones to scented candles to diffusers. When you diffuse essential oils, however, you receive the most scent coverage without waste or harmful side effects, like smoke. You can also effortlessly make custom blends to suit your mood or needs. Ultrasonic diffusers generally require between 6 to 18 drops of essential oil per day, depending on how long your session will be and how potent you want your fragrance.

With a diffuser, you can:

  • Clean your air
  • Have an aromatherapy session and diffuse essential oils
  • Replace your chemical air fresheners and candles with essential oils
  • Moisturize your skin
  • Replace air purifiers and ionizers
  • Replace your humidifier

You might be able to:

  • Get a better night’s sleep
  • Improve breathing symptoms associated with asthma, colds, and viruses
  • Relax easier
  • Improve concentration
  • Repel bugs
  • Save money
  • Reduce pain
  • Have a night light

How to Choose an Ultrasonic Essential Oil Diffuser Suitable for a Large Space

Ultrasonic diffusers do exceptionally well in living rooms, family rooms, and combination/great rooms. They work by combining a diffuser with a humidifier, and when the moisture releases into the air, the oil binds to the mist. source: verywellhealth.com

Other common home diffuser types and their uses:

  • Terra cotta—personal, drawers, and closets
  • Reed style—small spaces
  • Candle/tea light diffuser—small spaces
  • Ultrasonic diffuser—medium and large spaces
  • Electric diffuser—small spaces

Ultrasonic diffusers are essentially smaller versions of nebulizer diffusers and work in a similar way with some exceptions. Nebulizers are popular with businesses where one scent is used and typically only ever one scent. You attach the whole essential oil bottle to the device. While they’re powerful diffusers and offer exceptional coverage, they’re not practical for home use where you might change your scent daily. In addition, they are extremely noisy machines, whereas its ultrasonic cousin is whisper quiet.

Defining a Large Space

Living rooms, master bedrooms, and combination/great rooms are what manufacturers mean when they say large space. Keep in mind that there isn’t an industry-wide regulation or exact square footage; this varies by model and manufacturer. Higher capacity doesn’t always equal more square footage in relation to diffusers.

Unsure about your living room’s square footage? All you need is a measuring tape and a bit of math. Simply measure the widest and longest points of your room, then multiply them. That’s your square footage. Don’t worry about moldings and bay windows since you’re looking for a rough idea of your room’s size. source: homeguides.sfgate.com

Advantages of Large Room Diffusers

The greatest benefit of a large room diffuser? You will only need one diffuser. Some people prefer to use larger room diffusers in their bedrooms because it increases the aroma coverage without using more oil in a smaller machine. However, doing this will also increase the moisture in the room unless the model offers a variable to control the mist output.

Multiple functions is the second benefit. Often descriptions will say 3-in-1 or 5-in-1, which means the diffuser performs more than one function.

  • Humidifier
  • Air Ionizer
  • Air Purifier
  • Night Light
  • Essential Oil Diffuser

While these are marketing phrases, they are true. Any ultrasonic diffuser will perform the jobs of at least three machines: diffuser, humidifier, and air ionizer. Additionally, you can find models that also work as night-lights or have air-purifying capabilities.

Why You Need an Ionizer

Ionizing uses electricity to clean the air. Why is it an important advantage? Humidity, which is the main feature in a diffuser, breeds bacteria, viruses, and other icky things you do not want to breathe, but an ionizer cleanses the air of these harmful substances source: wisegeek.com

What Else to Look for in a Large Space Diffuser

  • Auto shut off for safety
  • Timer settings and/or continuous release options
  • Run time should be at least 8 hours
  • Mist output and settings should be adjustable
  • High-capacity water chamber of at least 500ml for less refilling and longer use
  • Ultrasonic technology, which adds to a whisper quiet experience
  • Night light

Common Issues with Oil Diffusers

Make sure to check your model and adhere to its cleaning schedule. They become smelly and grow mold/mildew if you neglect them. Most models recommend weekly cleanings, but some users will clean theirs after each use. Vinegar and water generally do the trick.

If you live in a high-humidity area, you might need to clean your machine more frequently than those who live in drier climates. This also applies to heavy pollen times when the air is more saturated.

Essential oil diffusers can clog or corrode if used with synthetic fragrances, which tend to have inorganic material. Please make sure you’re only using pure oils with no carriers or additives. If you’re taking the time to invest in a quality diffuser for your health and safety, only diffuse pure essential oils. source: draxe.com

The aim was to discover the true best and not recreate lists found elsewhere, which might’ve left off a major contender: the URPOWER 500ml. However, function and capacity became the driving force over popularity for creating the short list.

1. BESTEK Glass Aromatherapy Essential Oil Diffuser

BESTEK is a global leader in consumer home appliances who stand behind their consumer-driven products and designs. One feature I find enjoyable is their incorporation of glass in the design. It offers an elegance missing on models with similar features.

2. ASAKUKI Premium Essential Oil Diffuser

ASAKUKI, which means morning air, is a Japan-based company that combines style with technology and function. The square design might not be for everyone, but it’s streamlined and fits in more spaces than round versions. It also makes it more difficult to knock over, and if you have cats who love to knock things off shelves and tables, they’ll have a tougher time with a square model.

3. InnoGear 500ml Aromatherapy Essential Oil Diffuser

InnoGear is a well-respected maker of essential oil diffusers. One feature I enjoy with this model is the dimming lights. I suffer from frequent migraines with light sensitivity, but I’m not a huge fan of total darkness and anything too bright is still out. Dimming the light to a soft glow would allow me to see while relaxing and allowing the aromatherapy session to work its magic.

Size: 500ml
Continuous run time: 8-17 hours
Coverage: up to 1,000 square feet
Features: whisper quiet, 7-color night light, humidifier, air ionizer, air purifier, aromatherapy, BPA free, cool mist, auto shut-off, and offers great coverage

  • 8 hours in high mode/17 hours low mode
  • 3 timed modes are 60-minute, 120-minute, or 180-minute sessions
  • Hi/low mist setting
  • Continuous mode also available
  • High sq. ft. coverage for large rooms

4. PureSpa XL from Pure Enrichment

For run times, the PureSpa XL might be the longest running model out there. One downside to this unit is you have no pre-timed settings, and I’m a stickler for wanting presets that I can press and forget. It does mention an auto-shutoff feature, so if you do actually forget to turn it off after 22-50 hours, you won’t have to worry about breaking it or starting a fire.

Size: 2,000 ml/2-liter
Continuous run time: 22-50 hours
Coverage: up to 350 square feet
Features: whisper quiet, BPA-free, 7-color LED lights, high-capacity reservoir, ionizer, humidifier, aromatherapy, auto-shut off, and uses a cool mist

Pros

  • Quiet
  • Longest run times
  • High-capacity reservoir
  • Hi/low mist output settings
