Create the perfect sleep environment with the Purest sleep diffuser. Fill the bedroom with scents that signal to the nose-to-brain superhighway that it’s time to sleep and it becomes the start of a healthy bedtime routine. The Purest has a unique hinged lid that makes adding water and scents easy. Built-in storage for two scent bottles minimizes bedside clutter. Choose one of two scent intensity levels and 1-hour, 2-hour or continuous use timer options. The unit is controlled with quiet capacitive touch controls. Use Marpac’s unique scents, designed specifically for sleep, or use any essential oil scent.
