There is nothing more comforting than letting aromatic mist of lavender essential oil calm your senses. Aromatherapy truly offers countless health benefits to our body and mind.
Setting a professional aromatherapy session at your home is not difficult at all. Before only reserved for professionals, essential oil diffusers have now become accessible to each and every one of us.
Buying a right diffuser for a large room is definitely harder than setting an aromatherapy. Majority of diffusers available on the market today are intended for smaller bedrooms, kitchens, and offices. Not every unit is powerful enough to disperse the mist to all room corners. Some dispersion techniques are way better at covering bigger living areas than others.
For the convenience of every buyer, this article reviews best essential oil diffusers for large spaces currently available on the market. Our in-depth buyer’s guide will help you narrow down your selection pretty quickly.
Nebulizer Vs. Ultrasonic Diffuser
Over the years, people have developed a couple of different techniques of diffusing essential oils. Because of that, there are different types of diffusers available on the market today; and not every type is suitable for large spaces. Some produce a very light mist, while other release concentrated vapor that can reach remotest corners of the room.
Here are two best types of essential oil diffusers for large spaces:
Nebulizers are hands down the best type of essential oil diffuser. They break essential oils into fine airborne particles without the use of heat or water. The aromatherapy experience set by nebulizer is as pure and as raw as it gets. Essential oils are directly from the bottle dispersed into the air. The released mist is concentrated enough to cover up to 1000 square feet area.
Nebulizers work similarly as perfume atomizers. Air vacuums the essential oil from the attached bottle into the top of the tube. The continuous airflow then pushes nano-particles into the atmosphere. Without any heat or diluters, dispersed essential oil preserves its most valuable therapeutic effect that we can enjoy.
2. Ultrasonic Diffuser
Ultrasonic diffusers are almost as efficient and as powerful as nebulizers. They disperse a strong-enough mist to cover larger living areas. With the help of high-frequency ultrasonic vibrations, the water-oil blend within the reservoir is turned into tiny airborne particles. The water makes the released vapor less potent. As a result, the strength of some therapeutic effect may be slightly lowered.
Ultrasonic essential oil diffusers have gained massive popularity because of their quietness, safety, and easy maintenance. They are versatile little machines that can be set on different mist modes or used as humidifiers as well. They are available in different shapes and sizes, and their overall aesthetic fits every interior design theme.
|No heat or water required||Louder than ultrasonic||Operates quietly||Needs water|
|Concentrated mist||Uses more essential oil||More affordable||Citrus oils can cause corrosion|
|No interrupting lights||More expensive than ultrasonic||Can be used as humidifier||Mist is not as strong|
|Can cover up to 1000 sq ft||May not have any special settings||Requires only a couple of drops of essential oil||Some have lights that cannot be turned off|
|Some are made of quality wood and glass||Parts made of glass are fragile||Offers mist settings||Usually cover up to 400 sq ft|
Buyer’s Guide: What to Look for in a Diffuser
Here are some of the features you should look out for when buying essential oil diffuser for large spaces:
Every diffuser for large rooms should have a timer which will let you predetermine the length of your aromatherapy. Ultrasonic diffusers usually have a timer that can be set for 1 hour, 2 hours and 3 hours.
Some advanced models even offer 6 to 8-hour run, which is great for overnight aromatherapy sessions. Nebulizers, on the other hand, can be set to run for a couple of minutes, usually 15 minutes each hour. Such intermittent setting will help you save your essential oil.
2. Auto shut off
It is important that you look for auto shut off feature in your diffuser. The last thing you want is your diffuser still running after the tank has been emptied. This feature will allow you to fall asleep in presence of lavender mist without a single worry.
Noise is an often overlooked feature that can either make or break your aromatherapy experience. Loud diffusers are not suitable for bedrooms. Even if you intend on keeping your diffuser in a living room, the emitted noises will most likely annoy you.
Having a quiet unit is always preferable. Since the loudness of the motor cannot be checked in online stores, it is best if you look at the reviews and see if there are any complaints about the matter.
4. Tank size
When setting nebulizer, you only have to attach the essential oil bottle in the right place or add a couple of drops in the intended compartment. Ultrasonic diffusers, on the other hand, have specific tank intended for water and essential oil blend.
These water tanks vary in size, usually from 100ml to 300ml and more. You may want to consider buying a diffuser with larger capacity, so you do not have to refill the tank as frequently. It is recommended to purchase a model with an at least 400ml reservoir.
Price of essential oil diffusers varies based on their type, brand, and features. Nebulizers are usually more expensive than ultrasonic diffusers. You can find your ultrasonic diffuser bellow $20 while the price of nebulizers usually starts at $50.
If your budget does not allow you a big splurge, it is best if you compare prices. It is possible to find a quality diffuser at a low price especially if you have a promo code.
6. Warranties and guarantees
The price is not the only thing you should be looking at. Warranty is just as important. The majority of companies offer one year warranty. It is also recommended to purchase a diffuser with a money-back guarantee, especially if you are buying online. You never know what you are going to get in the mail. You will get a full refund in case you are not satisfied with the product.
