Let’s take a look at ultrasonic diffusers first. These have a water tank to which you can add a few drops of your favorite essential oil. Then the fragrance will spread throughout the room while the diffuser humidifies the air.
URPOWER 500ML Essential Oil Diffuser Humidifier Ultrasonic Aromatherapy
URPOWER has a wide selection of best-selling ultrasonic diffusers. This one has a 500mL capacity. As a result, it can run up to 10 hours on a full tank. And since the tank is made of food-grade plastic, you don’t need to worry about adding toxins to the air.
The attractive wood grain design is highlighted by a color-changing LED light. It’s possible to control the brightness of light as well as its colors. It rotates through seven colors, or you can set a single color or turn the lights off completely.
If the tank runs dry, the diffuser turns off automatically. Moreover, you can limit the continuous mist to run for only one hour, three hours, or six hours.
Aromacare Large Essential Oil Diffuser for Aromatherapy 600ml
Aromacare’s 600 mL diffuser operates up to 18 hours on a full tank. It’s quiet with a noise level below 35 dB. And it has both high and low mist modes.
The subtle coloring and dim lighting of this diffuser let it blend into the background. But it should cover at least 200 square feet. If you notice that the fragrance is waning after a few hours, you may need to add a few more drops of essential oil. In conclusion, Aromacare offers a 45-day money-back warranty.
ASAKUKI 700ml Premium Essential Oil Diffuser
The ASAKUKI ultrasonic diffuser has a 700 mL water tank that’s easy to clean. The fact that it’s straightforward to maintain is important. Cleaning the tank regularly ensures that the diffuser doesn’t send bacteria into the air.
Some of the highlights of this device are that it runs for hours but shuts off automatically when the water runs out. Next, it has an LED light that allows you to control the color and the brightness. Plus, there are three timed settings as well as high and low mist modes. Finally, the diffuser comes with a six-month money-back guarantee and a one-year warranty.
Square Aromatherapy Essential Oil Diffuser Humidifier, 700ml Large Capacity by TomCare
TomCare’s 700 mL ultrasonic humidifier runs up to 20 hours in low mist or 10 hours in high mist mode. The water tank is made of BPA-free plastic. In addition, it has similar features to other comparable diffusers.
For example, you can control the brightness and color of the LED light. Furthermore, you can set the diffuser to run for one, three, or six hours, or until the tank is dry.
URPOWER 1000ml Essential Oil Diffuser Humidifier Ultrasonic Aromatherapy
URPOWER also makes a 1 L diffuser that comes with a remote control. It runs for 20 hours in low mist mode on a full tank. Otherwise, you can set a timer for three, six, or nine hours of runtime. Of course, the humidifier will turn off when the tank is dry.
The wireless remote has a 5 m range, which is about 16 feet. It allows you to control both the light and the mist.
For those interested in specifics, the diffuser covers up to 430 ft.² for aromatherapy purposes. As a humidifier, it puts out 50 to 150 mL an hour. And for those planning where to place the diffuser, the power cord is 5 ½ feet long.
Signstek 1500ML 1.5L Ultrasonic Air Humidifier LED Color Changing Aroma Oil Diffuser
Signstek’s 1.5-liter humidifier has a striking design. The tank comes in two versions: one with a windmill and one with a dragonfly. The images are backlit by a color-changing LED light. Although you can’t fix the light to a single color, you can turn it off completely.
This ultrasonic diffuser covers over 200 ft.² and puts out 250 mL per hour of mist. At this rate, one tank lasts about six hours, but it fills a room very quickly.
PureSpa XL – Extra Large Premium Aroma Diffuser with 2,000ml Tank
The PureSpa XL Premium Diffuser has a 2 L tank that covers up to 350 ft.² and runs up to 50 hours. Although the 50-hour rating is for low mist mode, it still runs up to 22 hours in high mist mode.
The diffuser has a BPA-free plastic tank. On the front near the bottom, you’ll find two control buttons. Not only can you set the mist mode, but you can also control the rainbow of color changing lights. Also important, PureSpa offers a five-year warranty.
SimpleTaste 4L(1.06 Gallon) Ultrasonic Cool Mist Humidifier Essential Oil Diffuser
The gallon tank of the SimpleTaste ultrasonic humidifier runs up to 13 hours in maximum flow mode. Then it turns off automatically when the water level is low.
While the humidifier is running, it produces less than 35 dB of noise. For comparison, that’s less sound than a PC or refrigerator running.
There are several adjustments you can make to get the most from this humidifier. First, you can enjoy the seven-color light or turn it off. Then, you can adjust the mist nozzle 360°. Finally, you can set the timer on the digital display to one, two, four, or eight hours.
Unlike most of the other ultrasonic diffusers we reviewed above, this one has a sponge. The sponge is where you’ll place a few drops of the oil you want to diffuse. This complicates matters if you frequently switch aromas. Also, the tank uses a water filter which will need to be changed after 500 hours of use.
Now let’s switch to nebulizing diffusers. These devices don’t require water to operate. They atomize pure essential oil into tiny particles to fragrance room air. The advantage is that you won’t be adding humidity to the air if you live in a place where high humidity is a problem.
SpaRoom Theralizer Waterless Micro-Air Essential Oil Nebulizer
The SpaRoom Theralizer, like most nebulizing diffusers, works in short bursts. It turns on for two minutes, then off for one. Not only does this conserve electricity, but it maintains a pleasant scent without overwhelming the air with fragrance.
This particular diffuser is designed for rooms measuring 1000 ft.² or less. In other words, it’s ideal for large living rooms, family rooms, or bedrooms.
Also like many nebulizing diffusers, it’s built from hand blown glass with a wooden base. In the base is a dial that allows you to control the concentration of the aroma.
Something to note about nebulizing diffusers like this one is that you’ll need to remember to turn them off manually. There’s no automatic shutoff function. But it does have a built-in timer that will cause it to run intermittently for two hours.
Finally, SpaRoom recommends using 10 to 15 drops of pure essential oil each time. And it’s also important to clean the glass container regularly.
Nebulizing Pure Essential Oil Aromatherapy Diffuser
The nebulizing diffuser from Organic Aromas has a handblown glass reservoir on a wooden base. The plantation hardwood is coated with a water-based lacquer that does not off-gas.
The whisper-quiet air pump operates for two minutes on, one minute off, for up to two hours. It fills a room up to 70 m² (750 square feet) with fragrance. And it comes with a one-year parts and service warranty.
Aromis Wood and Glass Aromatherapy Diffuser
The Aromis diffuser covers up to 30 ft.² with the fragrance of pure essential oil. Feel free to use a single oil or make a blend of your favorite scents.
The advantage of this diffuser is that it runs for 10 minutes, then turns off for 10 minutes. After one hour, it shuts down automatically.
Like many nebulizing diffusers, this one has a glass reservoir and a wood base. It includes a one-year warranty for parts, replacement, and labor. Should there arise a problem after one year, there is a small cost for replacement parts.
Sofia Waterless Nebulizing Essential Oil Diffuser
The Sofia nebulizer was created in Italy. It has an oak base with a ceramic cover and two glass reservoirs. The benefit to two glass containers is that you can switch scents without having to clean in between.
This diffuser runs for two minutes, then shuts down for one. After two hours, it halts automatically. Also, it includes an LED light that runs separately from the diffuser.
Should there be a problem, the nebulizer has a one-year warranty.
Which type of diffuser is better?
Which kind of diffuser is best for essential oils? In our opinion, both kinds are. There are pros and cons to both nebulizing and ultrasonic diffusers.
Pros of nebulizing diffusers
Nebulizing diffusers disperse pure essential oil into the air. They don’t require heat to operate, so the oils don’t break down. Additionally, there’s no need to dilute the oils with water.
Cons of nebulizing diffusers
The disadvantage of nebulizing diffusers is that most only run for 2 to 4 hours at a time.
Pros of ultrasonic diffusers
The benefit of an ultrasonic diffuser is that it uses less essential oil than a nebulizer. Instead of 10 to 15 drops, you might add only five to the water tank. Also, if you live in an arid climate, this type of diffuser humidifies the air. Furthermore, some large-capacity ultrasonic diffusers can run up to two days on a single tank of water.
Cons of ultrasonic diffusers
If you struggle with too much humidity in your home, you might want to pass on an ultrasonic diffuser. Additionally, they don’t diffuse essential oil at full strength. The scent will be weaker than it would with a nebulizing diffuser.
Diffusing essential oils has several benefits. Not only can it help improve your mood, but it can make your home smell more welcoming. A diffuser can help you battle cold and flu season and diminish pet and smoke odors. We hope you discovered the perfect essential oil diffusers for large rooms today.
