→ All-night bedroom diffusing, large rooms
The design-forward mid-size — a sculpted 300ml diffuser with a whisper mode and softer aesthetics than the wood-grain crowd.
→ Modern decor, quiet operation, mid-size runtime
The value bestseller — 500ml capacity, adjustable mist and the wood-grain look that started the category, at a rock-bottom price.
→ First diffuser, second rooms, tight budgets
