Frequently Asked Questions

Which Diffuser Is Best?

What Is The Difference Between Heat, Fan, Vaporizing, and Atomizing Diffusers?

A diffuser is any device which allows a liquid to evaporate thereby putting a scent into the surrounding environment. If all you want to do is provide a pleasant scent to your environment, any diffuser will work fine. But if you want to use essential oils for their maximum natural qualities and powerful benefit, only an atomizing diffuser will do the job 100% effectively. Contact support@diffuserworld.com for additional help, or call 855-276-6277 x1.

The process of diffusion is typically accomplished in FOUR ways:

1) Heat - By applying heat, either through burning a candle, or by electricity, the increased temperature will cause the essential oil to evaporate into the air releasing an aroma.

Pros: Heat will gently produce a scent and fill a room nicely with only a minimum amount of essential oil. Most are economically priced.

Cons:  Heat has two drawbacks. First, it tends to alter the chemical composition of the essential oil which can destroy its purity. Second, it may not be as effective because the size and availability of breathable molecules are mostly filtered out by the nose hairs and nasal cavity.

Heat diffusers available on our website:  Scent Ball Home Essential Oil Diffuser,  Aroma-On-The-Go Car/RV Diffuser http://diffuserworld.com/markets/store/all-diffusers.html  

2) Fan / Ventilation - By utilizing a small fan to create airflow, evaporation is achieved when air passes over a wick or absorbent pad which holds the essential oil.

Pros: Ventilation offers an economical and simple way to provide evaporation. Since there is no heat involved, the chemical composition of the essential oil remains intact. Ventilation is a good way to scent a room as long as it’s not too large. Oil usage is minimal. Usually economically priced.

Cons:Aroma has limited reach. The minimal size and availability of breathable molecules compromises therapeutic benefits.

Fan Diffusers available on our website: Aroma-Sidekick™ Fan Diffuser Set, MIO Battery Operated Essential Oil Diffuser, SPAScenter Tabletop Diffuser  http://diffuserworld.com/markets/store/fan-diffusers.html

3) Vaporization / Humidification - By using water and essential oil mixed together, a mist can be formed which will fill the air. This mist is produced through ultrasonic waves assisted with a fan to force the mist into the environment.

Pros: Humidification alone has many benefits especially in dry climates. Also, the negative ions in the water vapor can help filter the air. Using vaporization with essential oils will produce a nice scent in an average sized room. Many vaporizers are equipped with colorful lighting, and a variety of timer options, and are whisper quiet. Essential oil usage is minimal. 

Cons: Humidification can be undesirable in high-humidity climates. It is a less effective way to provide aromatherapy because the majority of the mist is water vapor which quickly drops from the air. Most vaporizers will only run up to five hours on a single filling.

Vaporizing diffusers available on our website: Aroma-Spa Vaporizer™, Aroma-Classic™ Vaporizer, SHA Vaporizing Diffuser, Sprout Vaporizing Diffuser, YUN Vaporizing Diffuser, Commander Tri-Jet ® 672 High-Volume Forced Air Vaporizer http://diffuserworld.com/markets/store/vaporizing-diffusers.html

4) Atomization / Nebulization - This new technology uses a cold air pump to force essential oil molecules through an atomizer and into very tiny particles; these atomized molecules become a micro fine vapor that float through the air and keep your environment therapeutically rich for extended periods of time. 

Pros: Atomization is absolutely the best way to provide both aroma and retain natural properties with essential oils because it does not alter the chemical composition of the oils. It breaks down pure essential oil molecules without separation of the mixture. It produces a particle size small enough for the lungs and body to absorb them rapidly. Most are equipped with built-in timers and pressure output controls for full control over the oil consumption. No method of diffusing is as effective in preserving the natural healing qualities of essential oils. Diffuser World builds the atomizing diffusers in the USA.

Cons:  Units can be more expensive as it is more costly to create a steady pressurized air flow than to create heat or rotate a fan. Cold air jet technology is not silent. More oil is consumed.

Use and Care

Cleaning Guide

Diffuser World's diffusers are the most "easy to clean" diffuser systems on the market. For cleaning instructions, find your diffuser below:

AROMA-ACE- AROMA-WHISPER- AROMA-BREEZE

  • Quick-Clean: If you feel there could be an oil clog, then a "quick-clean" can fix the problem. Pour a little alcohol (Rubbing, Vodka, Ever-Clear) in an empty essential oil bottle and diffuse for a couple of minutes in a well ventilated area. You can also diffuse orange or lemon essential oils as they are natural cleaners.
  • Deep-Clean: To "deep-clean", first remove the atomizer attachment from its base. The oil clogs develop in the atomizer attachment, usually in the straw. Twist off the essential oil bottle. NEVER try to remove the straw piece in the atomizer attachment. Immerse the atomizer attachment in alcohol (Rubbing, Vodka, Ever-Clear). Let the atomizer attachment remain completely immersed in alcohol for some time depending on the thickness of the oil or resin build up, generally ten minutes. This will clean the build up and will not harm the diffuser. Rinse with warm water.
  • Clog Prevention/Maintenance: Run a "quick-clean" between each oil change or refill.
  • Warnings: If oil is leaking from ANY part of the unit, turn it off and start the RMA process so we can repair the diffuser. Do not set on any surface that can be damaged by essential oils. Only use in an upright position. Do not tilt unit with the essential oil bottle or atomizer attached. Remove bottle and atomizer attachment before transporting.

AROMA-PRO™

  • Quick-Clean: If you feel there could be an oil clog, then a "quick-clean" can fix the problem. Pour a little alcohol (Rubbing, Vodka, Ever-Clear) in an empty essential oil bottle and diffuse for a couple of minutes in a well ventilated area. You can also diffuse orange or lemon essential oil as they are natural cleaners. Other options are running the anodized well and glass piece through the dishwasher, or clean by hand with hot, soapy water.
  • Deep-Clean:  If oil has left a thick resin, let the well sit for 5 to 10 minutes in alcohol (Rubbing, Vodka, Ever-Clear). Also, give the silver cap a twist and poke a fine needle in the hole being sure to reach the second hole.
  • Clog Prevention/Maintenance: Run a "quick-clean" between each essential oil change or refill.
  • Warnings: Do not set on any surface that can be damaged by essential oils. Only use in an upright position.

AROMA-GLOBE™

  • Quick-Clean:  First, add a little alcohol (Rubbing, Vodka, Ever-Clear) to the glass bulb and diffuse for a few minutes in a well ventilated area. To remove the glass you must be very gentle to not harm the rubber piece in the base.
  • Clog Prevention/Maintenance: This is a very fragile diffuser and preventing clogs is very important. Run a "quick-clean" between each essential oil change or refill. We also suggest you diffuse thin essential oils like lemon or orange frequently as they are natural cleaners.
  • Warnings: Do not set on any surface that can be damaged by essential oils. Only use in an upright position.

AROMA-CLASSIC™

  • Quick Clean: This is a vaporizer, so it needs to be cleaned by hand. Wipe out the bowl with rubbing alcohol on a cloth. Wipe the disc at the bottom clean between uses as mineral deposits can collect there. It is an all-in-one unit and cannot go through the dishwasher.
  • Warnings: Do not set on any surface that can be damaged by essential oils. Only use in an upright position.

USB DIFFUSER / THE AROMA-CRYSTAL™

There are three things to be aware of when operating the USB diffuser. Do not run carrier oils or any blends if possible. The Piezo crystal screens are micro-small and can have trouble with high viscosity oils. As a rule of thumb, oils like or similar to lemon, lavender and peppermint are just fine. If the USB has stopped due to thick oils, use a cotton cue tip with alcohol to clean both sides of the screen. And lastly, if it doesn't seem to be putting the oil through and the user is using the correct oils, then use a Q-tip and press down on the screen from the top with some force to make sure it has not been pushed up from the bottom where the bottle is placed. We have found that when users put the bottle in the cartridge, they are pressing down with too much force and it is bending the screen upward. Once they release the bottle and put the cover on, the bottle will pull back slightly and will not maintain contact with the Piezo crystal screen. Once the screen regains contact, it should start diffusing again like a champ. Contact returns@diffuserworld.com for additional help, or call 855-276-6277 x3.

Set Up and Use

Congratulations on your purchase of the most advanced aromatherapy diffuser systems in the world! Please refer to the product instruction pamphlet that was included in your package. Below are some FAQ's:

  • How do I set the timers? The ON TIME and OFF TIME dials have a minimum length of 2 minutes and a maximum length 20 minutes and will repeat indefinitely until the unit it is manually powered off.
  • Do I add water? Only our vaporizer diffuser systems use water.
  • What kind of oil do I use? Our diffuser systems are designed for 100% pure essential oils. Some pure essential oils are thick and resinous by nature so running a thin essential oil like lemon or orange, or mixing a thinner oil with the thicker oils will keep these units from getting clogged. You cannot hurt your diffuser, so feel free to experiment.
  • Can I use smaller oil bottles on the atomizer? Yes, smaller bottles with the same collar size will work on the atomizer, but the straw may be too long. You can clip the straw to the correct length (cut on a slight angle). It is recommended you buy additional atomizers to accommodate straw length and to minimize blending of oils.
