AROMATECH AroMini BT Plus BT Plus Diffuser

Pure scent — and nothing else.
Our cold-air diffusers disperse scent using filtered air instead of water or heat. The result: a cleaner, more consistent scent experience.

Powerful.
Our cold-air diffusers cover twice the square footage of ultrasonics or candles.

Consistent.
Long-lasting fragrance is evenly distributed throughout your home.

The Magic of Nebulization

What is Cold-air Diffusion?
Cold-air diffusers disperse fragrance oils through nebulization—a process that breaks down scent oils into an ultrafi ne dry mist. The nanoparticles in this mist are so tiny that they remain suspended in the air for hours. This cutting-edge technology uses no water, alcohol or heat, diffusing scents in their purest form.

Why is it Better?
Cold-air diffusers can cover spaces twice as large as typical candles, reed diffusers, plug-ins and ultrasonics. They’re more consistent, ensuring fragrance is evenly distributed, and more precise, giving you the option to adjust the scent intensity. Our diffusers are cleaner because they neither dilute nor heat the scent oil.

Cold-air Versus Ultrasonic
No water, no mold—our cold-air diffusers have a number of benefi ts over traditional ultrasonics. They’re more powerful and use diffuser oils more effi ciently, so your scents last longer. They’re also far easier to use, you can go months between refi lls and no hands-on cleaning is required. In fact, a quick rinse with our cleaning solution is the only maintenance recommended.

Our Ingredients
We’re very particular about what goes into our diffuser oils—and what stays out. To craft the safest, purest and most beautiful scents, we use a mix of safe synthetic and naturally derived ingredients. All of our diffuser oils are sustainably sourced and made in the U.S.

Our Safety Promise
Our diffuser oils exceed the strict safety and environmental standards set by the International Fragrance Regulatory Association (IFRA), as well as the Volatile Organic Compound (VOC) guidelines set by the California Air Resources Board. They are entirely free of parabens, sulfates, synthetic colors and other harmful additives. Please note that our oils are for diffuser use only; do not use topically or ingest. Those with medical conditions should consult a health care practitioner prior to use.

3. Click “SAVE” to save changes.

Device naming tips:
Name your diffuser based on its location and scent to easily identify it when using multiple diffusers.

Step 6.
Now continue to set up your schedule and intensity. You’ll see some default schedules which you can edit. You can also add new schedules up to a total of five schedules per diffuser.

To set and edit schedules:

Continue editing and adding schedules until you’ve found the perfect set of schedules for your space and desired scenting experience.

Where to Place

The placement of your diffuser is important in ensuring your space is optimally scented.
The ideal placement should work with the natural flow of air. It’s important not to place your diffuser by an HVAC return grill, exhaust, fan, window or doorway as the scent will flow out of the room. Ensure that there’s at least 3 feet of clearance above the diffuser so that nothing is blocking the air from passing over the diffuser and dispersing scent in the room. We recommend trying a variety of locations and settings until you are satisfied with the scent coverage. Once you’ve chosen a good location for your diffuser it’s time to find your preferred scent intensity level. The higher the intensity level, the more scent molecules are diffused into the air. Different scents may require a different intensity level. We recommend starting at a low-intensity level and then working your way up, until you’ve found a level that creates your optimal scenting experience.
Note: that a larger room or a room with high ceilings will likely require a higher scent intensity level. Example of a 300 sq ft space for scent intensity versus ceiling heights.

When you first use your diffuser it’s important to let the scent disperse throughout the space. Refrain from changing the intensity level for about an hour.
Depending on the warmth of the room or if you change scents you might need to adjust the intensity level.

Tips for finding the right location:
Depending on the warmth of the room or if you change scents you might need to adjust the intensity level.

• Make sure the diffuser is on a flat, level surface and cannot be easily tipped over.
• Keep the diffuser out of reach of children and pets.
• Avoid getting aroma oil on wood or delicate surfaces. If oil drops occur on surfaces, clean with a damp cloth quickly to avoid leaving a ring or mark.
• Place your diffuser at least 2 feet off the ground.

Scent Intensities & Schedules

Schedule the AroMini BT Plus to welcome you home with your favorite scent.

Scenting

Explore the possibilities of scenting by changing the scent you use. Choose a cozy scent for the weekend and an uplifting scent during the week. Mark a special occasion or a party by choosing a scent that’s celebratory and fun.

Changing the Scent

Whether you like to redecorate your space to match the season or your mood, home scenting is a simpler and faster way to update your home or office.

• When scenting for the season opt for a scent that invokes the spirit of each season. Choose a revitalizing scent that is fresh, fl oral, or tea-infused. For sun-drenched summer days, a fragrance that contains fresh citrus scents and hints of coconut and sea air is recommended. During the fall a scent that contains woody and gourmand notes can create a cozy atmosphere. Switch to a rich scent filled with vanilla, cinnamon or tonka bean that matches the festive energy through the winter.
• You can even change your scent throughout the day. Choose an invigorating scent to encourage productivity and a relaxing scent for downtime. Choose a nostalgic scent for family time and a glamorous floral for celebrating. It’s easy to see how refreshing your space is easy with home scenting.

Maintenance

We recommend cleaning your diffuser every 1-2 months or when you change your oil.

1. Empty out any remaining oil in the Oil Vessel.
2. Pour a quarter inch of AromaTech Diffuser Cleaner into the empty Oil Vessel, reassemble the diffuser parts and run on the highest intensity setting for 15 minutes.
3. Discard the used diffuser cleaner, and screw in your favorite 60 mL AromaTech oil bottle, or refill the provided Glass Oil Vessel with your favorite AromaTech scent and enjoy.

Troubleshooting

My diffuser isn’t turning off?

To turn off your AroMini BT Plus you need to tap the power button twice – once to wake the scent intensity display and once to turn the diffuser off.

My diffuser isn’t staying on.
If your diffuser seems inactive, it’s likely in energy-saving mode. The scent intensity display will turn off, but the diffuser will continue to cycle on and off to maintain the desired fragrance level. You’ll notice the sound of the pump and mist as it continues to scent your space.
If you’re using schedules in the app, ensure that the preset timer on the diffuser is off (no light). Additionally, make sure that a schedule is set. Your diffuser will not turn on outside the scheduled scenting periods.

My diffuser is making a gurgling sound.

It’s likely that you’ve overfilled the Oil Vessel. Simply pour out some of the oil in the Oil Vessel. Be sure to only fill to the shoulder of the vessel and not to the very top.
Diffuser is running but no mist is visible and/or cannot smell the scent.

This may be for the following reasons:

• Your unit needs to be cleaned. To clean your diffuser replace the oil with diffuser cleaner and run on its highest setting for 15 min.
• You’ve run out of oil. Refill the Oil Vessel.
• The Diffuser Head is not fully installed into the Diffuser Base. There should be no large gaps between the Diffuser Head and the Diffuser Base.

The oil in my diffuser looks cloudy.
This is normal and will have no effect on diffusion. The nebulizer will aerate the oil in the Oil Vessel which might cause it to appear cloudy.

My diffuser’s shell is dirty, how do I clean it?
To remove smudges use mild soap with water on a micro fibre or soft cloth to wipe clean.
