4L Top-Fill Humidifying Diffuser — Whole-Room Scent & Mist

A 4-litre top-fill diffuser built for whole-room scenting and humidifying. The oversized tank means fewer refills and longer uninterrupted sessions — dial mist output up for a dry living room or down for quiet overnight bedroom use.

• 4L tank — significantly fewer refills than small-tank units
• Top-fill design — lift the lid and pour, no disassembly required
• Adjustable mist output — dial from high-output fill to gentle overnight level
• Timer & sleep modes — program once and let it run
• Auto shut-off when the tank empties, for worry-free overnight use
