ARO PRO Smart HVAC Scent Diffuser Up to 4,000 Sqft - Bluetooth & Waterless

ARO PRO is an HVAC-capable and standalone waterless cold-air scent diffuser for spaces up to 4,000 sq ft (maximum at a standard 8 ft ceiling) — large homes, restaurants, wellness centers, open offices and other commercial spaces. It is Aromely's best-selling diffuser.

How it works: two-fluid atomization turns Aromely fragrance oil into a dry micro-mist with no water, no heat and no flame. Control it over Bluetooth with the free Aromely app: set weekly schedules and intensity (seconds working / seconds pause), and use the multispeed fan to make the scent lighter or stronger.

Placement: connect the included hose to the air-supply side of your HVAC system to scent every room served by that air handler (one unit per air handler; closed rooms need their own unit), or run it standalone on a table, on the floor or wall-mounted. Space-saving unit with a lock on the front.

Specs: 800 ml internal bottle · recommended oil 500 ml · 11.6 × 7 × 3.5 in.
