Autivara Reservoir — 4L Humidifying Diffuser

The big-tank workhorse of the range — a 4-litre reservoir that humidifies and scents a whole room for hours before it needs another fill.

• 4L large-capacity tank — far fewer refills than a novelty diffuser
• Dial the mist up for a dry living room or down for an overnight bedroom setting
• Top-fill design — just lift the lid and pour, no flipping the base
• Timer and sleep modes to run it and forget it
