The Details
The Halo+ is Alloscent's flagship waterless diffuser — hand-thrown in small-batch ceramic and engineered around our quietest ultrasonic core yet. It's built for rooms that already feel considered: a bedside table, a reading nook, a nursery. Fill it, press once, and let it run near-silent through the night.
Available in 8 hand-glazed colorways, each one finished by hand, so no two vessels — and no two rooms — are ever quite the same.
