    • Clean the mist tube: Dip a cotton swab in 90% isopropyl alcohol and clean the base of the mist tube located at the bottom of the diffuser head.
    • Prepare the cleaning solution: Fill the provided empty 15 ml bottle with 90% isopropyl alcohol.
    • Run the diffuser: Attach the cleaning solution bottle to the diffuser and run it on high for 30 minutes. This helps clear any buildup in the system.
    • Replace the cleaning bottle: Turn off the diffuser, remove the cleaning solution bottle, and replace it with your SereneScent™ Essential Oil.
    • While the 60 ml bottles are Costco exclusive, our SereneScent 120 ml and 15 ml size refills offer unbeatable savings and a wider variety of scents—enjoy more for less!

    • The diffuser is designed to mist and pause at different times based on the intensity setting you choose. The unit does not mist continuously.
    • When the diffuser is set at level 1, it will release mist for a short amount of time and then take a long pause. When the diffuser is set at level 3, it will release mist for a longer amount of time and take a shorter pause. The unit does not mist continuously.

      At low fragrance mist intensity (1), the paused period is approximately 4 minutes.

      At medium fragrance mist intensity (2), the paused period is approximately 2 minutes.

      At high fragrance mist intensity (3), the paused period is approximately 1 minute.
    • There are 3 fragrance mist intensity levels, 1 (low) being the least intense and 3 (high) being the most intense. Adjust mist intensity to a higher or lower intensity level based on preference.
    • SereneScent 15 ml oils last up to 30 days.*

    • **15 or 30 days of operation at 8 hours per day and middle intensity level 2.
    • Your diffuser will only work properly when using SereneScent oils. Use of any other oil is not recommended and will void diffuser warranty.
    • Make sure the power is ON. If there is still no diffusion or it is weak, remove the oil bottle. Fill the empty bottle that came with diffuser with rubbing alcohol and run it through the diffuser for 30 minutes.

    • The diffuser works very much like your Bluetooth speaker or other similar devices. Anyone in range of the product while in pairing mode will be able to connect through the app.
    • When in the app, you will go to the Settings tab, then click Device Management. From there, it will say Delete Device at the bottom of the screen. Once you do this, the app will immediately go into search mode and will allow you to connect to any additional device around you. In the future, you will be able to be connected to multiple devices at one time and toggle between them. We are working on this feature and will update the app soon!
    • Each device has a unique Product ID. The last 4 numbers/letters that you will see when connecting to your device or when you look up your device name in the Settings tab under Device Management are unique to your device. So, as an example, what you will see is ARMH-972 FAE5. The FAE5 would be your device's UNIQUE ID. Remember or mark which diffuser is which so you can easily recall them! In the future, we will allow you to name your diffuser for it to be even easier for you.
    • You must have the schedule toggled OFF while you are setting your schedule. Once you have completed setting your schedule from there toggle schedule ON to save it.
    • Check the schedule toggle is ON

      If while a schedule is active, you manually change any setting such as intensity, lighting or time (from physical device or from app) then the scheduler will be negated. After any manual operation you should toggle your schedule Off then On to ensure it is set again.

      We have heard feedback from our valued community and are working quickly to change this to be more user friendly. We appreciate the great feedback and patience while we quickly make these changes.

  • Although Homedics SereneScent™ is made from essential oils, we should always exercise caution when using essential oils around our pets. Keep all products out of reach of pets. Keep open bottles away from pets to avoid internal consumption. When diffusing, always diffuse in a well-ventilated area and leave an option for them to remove themselves from the space. Every animal is different, so carefully observe how each animal responds when introducing essential oils for the first time. If irritation occurs, discontinue use. We recommend seeking medical attention if ingestion of essential oil occurs.
