Yes, our ScentFlow scent diffuser machine is compatible with iOS and Android devices, allowing you to control the schedule and intensity level of your diffuser via bluetooth.

The placement of the device 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 scent machine by an exhaust, fan, window or doorway as the scent will flow out of the room. Ideally there’s at least 3 feet of clearance above the scent machine so that nothing is blocking the air from passing over the machine and dispersing scent in the room. We recommend trying a variety of locations and settings until you are satisfied with the scent coverage.
