We recommend the use of pure natural essential oils for the operation of your aroma diffuser.

To begin with, you can add 2-3 drops of the scented oil to the water. Depending on the desired intensity of the fragrance, you can increase or decrease the number of drops.

If you barely smell the scent, please look at the list with recommendations:

  • Increase the amount of oil/fragrance drops in the diffuser.
  • Try different kind of fragrances/essential oils.
  • How much the scent is noticeable depends mostly on the quality of the fragrance itself (synthetic, natural, ingredients, etc.). It is comparable with wine; quality is everything plus the scent also changes over time. Our experience is that the best results are achieved with 100% pure essential oils of a high quality and concentration.
  • The room temperature and relative air humidity influence how noticeable the scent is. The drier the environment, the less noticeable is the scent.
  • A high rate of air ventilation (opening windows and/or heating/air conditioning) has a direct influence on the scent because it makes it disappear faster. Reducing the air ventilation and not putting the aroma diffuser next to an air vent helps to increase the time the scent remains in the air and thus the noticeability. This also means no tilted windows.
  • Make sure the aroma diffuser is positioned where you like the scent to be most noticeable, best at least 70 cm above the floor.
  • Clean the inside of the aroma diffuser at least once a week and make sure to thoroughly clean the transducer from any oil/scent residues. The transducer can be clogged which results in a lower output and less noticeability of the scent.

Yes, Sophie has a battery with a running time of up to 11 hours. The battery must be fully charged for at least 12 hours before using it for the first time.

As soon as the LED on the back starts flashing, Sophie must be recharged. We recommend that you don’t use the aroma diffuser while it is charging so that the battery can be fully charged as quickly as possible.

Sophie is IP44 certified and therefore splash-proof. You can leave your Sophie outside in a sheltered spot without any worries - however she should not be directly exposed to rain. It is important to use the cover for the USB-C cable socket during outdoor use, i.e. to cover the socket with it.

You can clean the water container using a common household descaler. Mix the descaler with water according to the instructions on the packaging. Please do not attempt to chip limescale deposits off the membrane using a hard object. In the case of stubborn limescale deposits, we recommend repeating the descaling process several times in a row. Make sure that no water gets into the air outlet opening. After descaling, carefully rinse out the base and dry it thoroughly. The upper part made of polycarbonate can be cleaned in the dish washer.

1. Unplug Sophie
2. Empty Sophie water tank and rinse it out with warm water
3. Plug Sophie back in again
4. Press and hold down the LED button first and then also press the ON/OFF button
5. Hold down both buttons for approximately 2-3 seconds
6. After that, the LED should flash twice
7. Refill Sophie with water and switch her on again

We do not recommend you to use Sophie with distilled water only.

Only use a power adapter with the following specifications: DC 5V / 2A

The device will switch off automatically when there is no water left in the water container. Sophie will not be damaged if she runs out of water.

You can find the USB-C cover on the insert accompanying the user manual. If you intend to use your Sophie or Sophie little in an outdoor setting, make sure to place it only in a sheltered location where direct rain or snow cannot reach the device.

Make sure that the LED dimmer is deactivated (press the right-hand button on the front several times: normal – dimmed – switched off). If there are limescale deposits on the membrane, Sophie's mist may be less distinct or less powerful.

If that is the case, you can clean and descale your Sophie thoroughly, paying particular attention to the membrane. We recommend wiping the membrane carefully with a cotton bud soaked in descaler until all the limescale has gone. Under no circumstances should you attempt to chip limescale deposits off the membrane using a hard or pointed object!

After cleaning, rinse thoroughly with clean water. Make sure that no water gets into the air outlet opening (9) during cleaning or rinsing.
