 Info

International Hopewell Pro with Variable Output and Timer built in.
Made in the USA - 5 year manufacturing defect warranty
If the motor is damaged due to misuse, the manufacturer will typically be able to repair/replace the motor for about $40.

This is the same model as the Hopewell Pro which features a very compact model, and instead of the atomizer attaching to the motor via tubing, it is secured directly on the motor. The International Pro comes with 4 power adapters to fit the various plugs in different countries. Our International Pro diffuser will work with any voltage and any frequency because it converts the power to 12 volts DC, and the frequency (Hz.) does not matter. It has a 5-year warranty for manufacturing defects.

Our other diffusers will NOT work properly with a typical, international voltage converter that converts the voltage from 230 volts to 120 volts because the frequency needs to be 60 Hz. for the motor to operate at full power. Even if you have a power converter to convert 230 volts to 120 volts, these converters do not affect the frequency, and at 50 Hz. the pump will only have ? of the power that it would have at 60 Hz. Our International Pro diffuser will work with any voltage and any frequency because it converts the power to 12 volts DC, and the frequency (Hz.) does not matter. The manufacturer will not warranty the non-international diffuser if it has been run on 50 Hz. power.

The following information is the same also found on the Hopewell Pro detail page:

The Hopewell Pro is a break through in cool diffusion technology, which produces a micro-fine vapor, preserving the natural essence of essential oils without heat or water.

Features

Directional control spout with optional sound reducer attatchment available
Nebulizer technology atomizes a micro-fine essential oil vapor of approximately 1-3 microns
Bottle top "quick change" system allows oil changes without mixing or spilling
Non-slip grip for easy pick up
15 mL capacity for extended operation and low maintenance intervals
Powerful, fully adjustable pump delivers up to 5 pounds of pressure
Strong molded body for increased service life and durability - compact one piece design for space efficiency
Tip resistant base for added stability
Built in filter to clean the air and keep dust out

The Pro uses a virtually unbreakable atomizer that screws onto your 15 mL essential oil bottle to diffuse 100% undiluted essential oil. Using a typical essential oil bottle eliminates the fragile nature of other nebulizing diffusers without sacrificing quality and effectiveness. The Hopewell Pro is a very compact model, and the atomizer is secured directly on the motor.

WARNING: Always keep the Hopewell Pro in an upright position when oil bottles are attached. The air pump can be damaged if the unit is tipped over, as this may allow essential oil to enter the air pump, causing damage. Remove the atomizer when transporting the unit or changing oils. If concerned about this possibility, please consider getting the Whisper model, where the atomizer is separated from the motor by tubing, which prevents this from occuring.

The Hopewell Pro diffuser has variable controls for time on/off and volume of output. The Whisper, Pro and Breeze model diffusers use a cold-air jet pump to force essential oil molecules through an atomizer and into a micro-fine vapor, yet the chemical composition of the oils is retained. The vapor reaches up to a 1000 square foot area and stays suspended, for up to two hours.

The advanced interval timers allow complete control of how long the unit is "on" or "off" as well as volume of output. The higher the output, the louder the sound of air passing through the orifice on the atomizer will be. On low, it's very quiet. It is extremely effective at atomizing essential oils into a micro-fine vapor that is dispersed into the air for better absorption into the lungs. The quick change atomizer system makes it easy to switch oils to be diffused, and there are no delicate glass parts to worry about breaking or getting clogged.

The atomizer breaks the oil down to 1-3 microns on low or high settings. The micro mist will stay suspended in the air for 2-3 hours at a level of 4-6 feet in the air and will ultimately evaporate rather than settling on surfaces. Nevertheless, we strongly encourage you to protect the surface where you place the atomizer.

Running the diffuser at high output pressures and short timing intervals maximize particle breakdown and therapeutic benefit.

Timer and Output Controls
The Hopewell Pro has a timer that controls the how long the diffuser runs (maximum 20 minutes) and a separate timer that controls the how long the diffuser is off (up to 20 minutes off). It will run 24/7 until you turn it off. While it is best to unplug when not in use, no harm is done if the diffuser runs continuously, even if the essential oil bottle has been emptied.

Usage Rate
As a point of reference, if you turn the output to maximum and run it for an hour, it will use about 3 mLs of an essential oil like Orange or Lemon, which are light oils that are consumed more quickly than others. The manufacturer says it will diffuse about 1.2 to 1.7 ml per hour depending upon the pump pressure. On one occasion when struggling with respiratory congestion, we ran our Pro/Whisper diffuser on medium low for 8 hours nightly with the cycle on for 5 minutes and off for 20 or so minutes, and a 15 mL bottle of Respiratory Relief lasted about a week. We have run a bottle of Respiratory Relief on full output settings, always on and virtually no time off, and 8 hours later we had diffused 1/2 of the bottle.

The diffuser is "gravity fed" in the sense that there is nothing forcing the oil up through the straw to be atomized in the atomizer. The oil is its heaviest when the bottle is full. Heavier oils will diffuse slower because of their thicker viscosity and thinner oils diffuse faster. When the bottle is at the halfway point, the diffusion rate goes down because it is not as heavy.

It does not harm the pump to run continuously, even if you run out of oil. Like a pump for a fish tank, these pumps are designed to run for years.

I add citrus oils to the thicker oil that remains near the bottom of the bottle. There are times when I like to change the oil or start over. When this is the case, I add a little food-grade alcohol to the thick oil in the bottle, shake it well and add it to a homemade cleaning product.

Usage rates have several variables to consider. Each diffuser pump has a range of pressure that is allowed when they are built and tested. The higher the pressure, the faster the oil will diffuse. The lower the pressure, the slower the diffusion.

The Whisper and the Pro have the same pump, but the way the Whisper pump is encased to make it quieter makes the diffusion rate lower. The manufacturer doesn't have any usage rates on the Whisper, but they have tested the Pro and feel that we can assume the rates would be similar. Not exact, but similar.

The usage rates with the Pro are as follows; Usage rates when the bottle is full ranges from .81ml - 1ml per hour on the highest end of usage that we can calculate. The settings for the test were: 1) Run time on the highest setting, 2) Rest time off, and 3) Full output. When the bottle reaches the halfway point, the diffusion rate goes down to .7ml per hour.

Please Note: These settings are not for normal home or therapeutic purposes. The settings that were tested are used for mold remediation or for someone who has a larger space, such as commercial businesses. Typical settings would be 5 minutes run time, 20 minutes rest time and output at about 1/4 of the way on.

A fun thing to know about our atomizing diffusers is that you don't need to run it a lot in order to receive therapeutic value from the oils. For every 15 minutes that you diffuse, the oil will stay suspended in the air for about 75 minutes. So the essential oils will be around for a while after you shut it off.

Mold Remediation
Running the unit on HIGH continuously the Pro diffuses approximately 20-24 ml within a 24 hour time frame. The Whisper should be similar.

Therapeutic Benefits

In his Essential Oil Master Safety Class (2018), Robert Tisserand said:

"In terms of therapeutic benefits, short-term diffusion and/or inhalation is shown to be more beneficial than if the essential oil is vaporized constantly. For intense inhalation, sessions of up to 15 minutes are recommended. For environmental diffusion, up to 60 minutes per session is advisable." Another suggestion is to set the diffuser to cycle on for 10 minutes and off for 20 minutes. Following these suggestions will prove to be more beneficial than continuous diffusion and will help prevent olfactory fatigue.

“Intermittent diffusion is much more effective, as well as being safer, than continuous diffusion. Intermittent means 30-60 minutes on, then 30-60 minutes off. This is because our body, especially our nervous system, habituates after this length of time. With continuous diffusion, while benefits do not increase, there is evidence that the body becomes stressed in various ways. However, very low levels of diffusion, so the essential oil is barely noticeable, are fine anywhere, for any length of time.” Robert Tisserand

- Higher pressure means more abundance of micro-fine oil droplets less than 3 microns (the size required to penetrate deep into the olfactory system and enter directly into the blood stream.
- Smaller particles stay suspended in the air for longer periods so you get more health benefits from less oil.
- Short run time (on time) allows complete control of how much oil is diffused per hour.
- Rest time (off time) gives you the option to conserve oil like never before.

Comparing Hopewell Diffusers

Breeze: Has variable output control, but no timer. The motor is separate from the atomizer, which allows the motor to be on the floor and the atomizer on a night stand. If the atomizer is tipped over, the oil is not likely to seep back into the motor. We strongly suggest you purchase a timer for this model so you can easily control when it cycles on/off.
Comes with a 1-year manufacturing-defect warranty.

Pro: Compact, all-in-one thus more portable. Has a variable timer and output control. If this gets tipped over, the oil is very likely going to seep into the motor and cause it to fail. Repair by the manufacturer is typically $40. Comes with a 5-year manufacturing-defect warranty.

Whisper: Very quiet. Has a variable timer and output control like the Pro. The motor is separate from the atomizer, which allows the motor to be on the floor and the atomizer on a night stand. If the atomizer is tipped over, the oil is not likely to seep back into the motor.
Comes with a 1-year manufacturing-defect warranty.

Aroma Scents: A Humidification/Vaporization diffuser allows you to enjoy a pleasant aroma in your home and avoid toxic commercial candles, air freshener sprays and deodorizers. It provides a safe, uplifting aroma as well as some health benefits. Due to mixing essential oils with water, it has more of a limited therapeutic effect since the heavy water molecules will quickly carry the essential oil to the floor.

Compare Vaporizing Diffusers with Atomization Diffusers

Humidification/Vaporization (such as Hopewell's Aroma Scents): A Humidification/Vaporization diffuser allows you to enjoy a pleasant aroma in your home and avoid toxic commercial candles, air freshener sprays and deodorizers. It provides a safe, uplifting aroma as well as some health benefits. Due to mixing essential oils with water, it has more of a limited therapeutic effect since the heavy water molecules will quickly carry the essential oil to the floor.

Nebulization/Atomization (such as the Hopewell's Breeze, Pro and Whisper): Using a diffuser that atomizes 100% essential oil as a mist into the air is an excellent way to provide both aroma and therapeutic benefits with essential oils. It does not alter the chemical composition of the oils as it breaks down pure essential oil molecules into a micro mist vapor. It produces a particle size small enough for the lungs and body to absorb them rapidly. The atomized mist hangs in the air for lengths of time, thus these diffusers are best used with timers for low output and short run times, which also economizes the use of the essential oil diffused.

WHY DIFFUSE?

Other than simply inhaling the oils, the easiest and simplest way of putting essential oils into the air for inhalation is to use an aromatic diffuser. A cold-air diffuser uses room-temperature air to mist the oil up through a nebulizer/atomizer. This creates a micro-fine mist that is dispersed into the air. The oils will then remain suspended for several hours to freshen and improve the quality of the air. The antiviral, antibacterial and antiseptic properties of essential oils may help reduce bacteria, fungus and mold. Essential oils, when diffused, have been found to reduce the amount of airborne chemicals. Many essential oils, such as Lemongrass, Lemon and our blends of Purify, Citrus Blessing, Immune Support and Plague Defense are highly antibacterial and may effectively eliminate airborne germs and bacteria.

If the goal is to get the essential oil into the bloodstream, inhalation is the most efficient way to deliver essential oils to the whole internal system of the body as they cross into the bloodstream through the lungs. The internal lining of the respiratory system is a mucous membrane, which is thinner than our external layers of skin, so inhaling essential oil has much quicker access than topical application. This rapid absorption into the bloodstream has a direct effect on infection and congestion within the respiratory system and on the central nervous system. Also, inhaled oils interact with cells at the back of the nose and can stimulate a change in the areas of the brain that control nausea and vomiting as well as sleep and mood. Inhalation is the safest method of essential oil use (although those with asthma or severe allergy sensitivities may have issues to consider).

When using on a daily basis, we suggest a very low level of diffusion so that the aroma of the essential oil is faintly noticeable, which in an average-size bedroom would only diffuse a few drops daily. Daily diffusion over many weeks or months may not be in the best interest of most children, as we feel it's important for their immune systems to be challenged so that it learns to fight. Intermittent diffusion is suggested where the diffuser cycles on for a time, such as 20 minutes on and 20 minutes off. In our family, we diffuse 5 minutes on and 20 minutes off. Intermittent diffusion is effective and safe for children.

There are times when we want to diffuse to support our immune response or recovery from an illness. Robert Tisserand: “Intermittent diffusion is much more effective, as well as being safer, than continuous diffusion. Intermittent means 30-60 minutes on, then 30-60 minutes off. This is because our body, especially our nervous system, habituates after this length of time. With continuous diffusion, while benefits do not increase, there is evidence that the body becomes stressed in various ways. However, very low levels of diffusion, so the essential oil is barely noticeable, are fine anywhere, for any length of time.” Low level, intermittent diffusion is effective and safe for children.

Unlike candles or aroma lamps, cold-air diffusers disperse oils without heating or burning, which can render the oil therapeutically less beneficial and possibly create toxic compounds. Burned oils may become carcinogenic. Cool, micro-mist (atomization) is considered the best way to provide both aroma and therapeutic and/or value with essential oils. It does not alter the chemical composition of the oils, while it breaks down the molecules and produces a particle size small enough for the lungs and body to absorb rapidly.

Research and/or antidotal testimonies demonstrate that cold air diffusing certain oils may:

• Reduce and eliminate bacteria, fungus, mold

• Relax the mind and body, relieve tension and clear the mind

• Improve concentration, alertness and mental clarity

• Stimulate neurotransmitters

• Stimulate secretion of endorphins

• Stimulate growth hormone production and receptivity

• Improve the secretion of IgA antibodies that fight candida

• Improve digestive function

• Improve hormonal balance

• Relieve headaches

• Dispel odors

Cinnamon bark, Oregano, and the oils found in our Plague Defense blend were all tested by Weber State University and shown to kill 100% of the airborne bacteria present when diffused into the atmosphere.

Diffusing may help eliminate allergy symptoms, and Tisserand writes that "there is no documented evidence of inhaled allergy to any authentic essential oil, the only existing evidence relates to fragrances."

Cleaning Instructions
Hopewell Diffuser atomizers have been carefully engineered for easy cleaning and operating simplicity. We believe that they are perhaps the most "easy to clean" system on the market. We personally try to run Lemon essential oil through the diffuser weekly to keep it clean. Lemon acts like a solvent to remove sticky build up. Another good option is a food-grade, 190-proof alcohol such as Everclear.

Avoid
We avoid diffusing thick essential oils such as Sandalwood, Myrrh, Patchouli and Vetiver, as they are thicker and may clog your atomizer. If you need to diffuse a thicker oil, try diluting it with a thinner oil such as Lemon.
**Do NOT diffuse an oil with a carrier oil in it.**

Very important: Diffuse only quality oils, some fragrance oils have been diluted with a carrier oil. Our diffusers are designed for 100% essential oils. Carrier oils are too thick and may clog the atomizers. Some pure essential oils are thick and resinous by nature, so running a thin oil such as Lemon, or mixing a thinner oil with the thicker oils will help keep the atomizers from getting clogged.

If your diffuser gets clogged or begins to run sluggishly, then a quick clean should fix the problem.

How to clean:
If the unit is not completely clogged, you can add 190-proof alcohol (Everclear) to an empty essential oil bottle and diffuse in an empty room to avoid breathing alcohol. If the unit is too clogged to push the air through, then a deep clean will be required.

1. Remove the atomizer attachment from its base. The oil clogs develop in the attachment piece.
2. Once the attachment has been removed, remove the essential oil bottle, but do not remove the "straw" from the device.
3. Immerse the atomizer attachment in alcohol. A mason jar works great, you can use rubbing alcohol, vodka or Everclear. Let the atomizer attachment remain completely immersed in alcohol for some time depending on the thickness of the oil buildup or resin. Ten minutes may be enough, but overnight may be better. This should clean the oil resin buildup and will not harm the diffuser.
4. Rinse in warm water and let dry.
5. Once dry, reconnect it to the essential oil bottle and diffuse. Be sure it's completely dry. You don't want water in your essential oils. You may want to diffuse some Everclear for a few mintues to be sure it is completely unclogged.

Customer's Testimony about Cleaning her Atomizers
Deb emailed us about the diminished diffusing she was experiencing.

You were right — it was the atomizers. I had cleaned them by following the suggested methods (alcohol then soapy water), but apparently they were still clogged. I thought I would share with you the method that finally did the trick. I heated up some water in a pan on the stove. As it was VERY HOT, I added some dish soap. The parts soaked for about 5 minutes. I then used tongs to remove them. I rinsed and dried them and let them set overnight. Now they work like new. I don’t know if this method is “manufacturer approved” but it worked for me! I happen to prefer the heavier essential oils such as Pine, so they will probably need this maintenance more often. Again, thanks for your help. - Deb

Testimonies
1. We have had the Hopewell Pro for about a month now. Love it. I didn't want the Whisper b/c of the tubing (I have a 2 and 4 year old and felt like it was too much temptation), but I do love how incredibly quiet the Whisper is. That said, we usually run the Pro on med-low at night and during nap time for my 2 year old, and it doesn't bother him at all. And I've run it in my room on medium, and it's like white noise. It is quieter than my humidifier, for sure. - Kelley

2. I have the Pro and love it. It's very portable and small. I use it all the time all over the house. In fact, I'm considering purchasing a second one. - Stacy

3. We love the Hopewell Pro! We've had one for several years. I actually gave it to our son for his family, bought another for us, and then bought one for our other son and his family. It surprises me how little oil it uses when just diffusing at night for sleep or whatever. But, more is used during illness. The versatility of being able to adjust the output and time it is on/off really makes this THE premiere diffuser, in my opinion. And it's such a convenient size for traveling. We always take it when we travel anywhere. Suzie

4. I love the Pro. It's so little. We are trying to de-humidify here in Louisiana! I do agree that it is a great idea to read about them on Amazon. So much info. We have had the air blowing ones, the ultrasonic water ones, and the heated pad ones. They all have their place, but using the Pro overnight has been best for helping with respiratory stuff and allergies. - Mary

5. I have an HEO Pro Diffuser. We had a fire in our house a week ago Saturday. I have been diffusing Purify most of the week. I had a 30 ml bottle of it and started diffusing Saturday night. I had it on all night, all day Sunday and off and on most of the week at 20 min on and about 5-10 min off with the output at about medium (pointing straight up). Sometimes I would turn it off at night, but not always. The bottle still has a good amount of EO in it. I did have to pour it into a 15ml bottle at one point because the tube was too short, but still... there is good amount in the bottle. I'd say a little less than 1/3 of it left. I am surprised that I have as much left as I do. I kept checking it because I thought it would be empty, but it wasn't. I wanted to share this because I know some are afraid to diffuse the oils for fear of 'wasting' them or it using too much. The HEO diffusers use very little oil and are very effective. - Stacy

6. I the Pro diffuser and can attest to the fact that they use very little oil! - Margie

7. Hopewell Pro is tops, hands down. I love that it has a timer, variable oil output and works by directly dispersing the oils instead of them being diluted in a mist or heated in some way. Easy to take when traveling, easy to move from room to room if need be, easy to clean. Worth every cent it cost, and then some! - Susie

8. I have both the Hopewell Pro and Whisper diffusers. Both are quiet, efficient and carry the oils over a LARGE area. - Laurie

9. I've been using the Hopewell Pro for years, and I think it's the best. I love that it has the adjustable output as well as the timer. Recently I was using it in the basement with Germ Buster and I forgot I had it on down there! It had been diffusing 24/7 for 2 days and the EO was not diminished all that much, so I also feel it is economical. I have bought a misting diffuser in the past couple of years and I like it okay, but there is no comparison really, in my opinion, particularly if you are wanting to diffuse for therapeutic reasons. I like the mist one for adding some humidity to the air in the winter and for some fragrance, but the fragrance diminishes after awhile since it's diluted. The Hopewell Pro is my go-to diffuser, and I travel with it also since it's compact and easy to use wherever. - Suzie
