Short answer: The JCLOUD A-326 is a slim column-style waterless scent diffuser for homes, offices and open rooms up to 1,000 sq ft. It combines cold-air diffusion, simple button controls, app scheduling and an independent warm ambient base light in a compact aluminum design.

A-326 turns compatible diffuser oil into a fine, dry fragrance mist without water or heat. Use the front controls for quick adjustments, or create repeatable scent schedules in the compatible app. The scent function and base light can be used independently, so you can run fragrance with the light off or use the soft glow by itself.

Why choose the A-326?

Waterless cold-air diffusion: Uses compatible fragrance oil directly without adding water.
Up to 1,000 sq ft coverage: Designed for living rooms, home offices, bedrooms, studios and other medium-to-large spaces.
Five scent levels: Adjust fragrance output to suit the room, airflow and oil.
Four timer choices: Select 1, 2, 4 or 8 hours from the control panel.
App scheduling: Create repeatable scent routines when you want more detailed timing control.
Independent ambient light: Use the warm base light with or without fragrance.
Slim aluminum body: A compact column design for desks, nightstands and side tables.
