oud diffuser

Typical oil or water capacities shown are 100 milliliters (mL) and 200 mL. Some ultrasonic units explicitly list a 200 mL water tank.

Most reed diffuser sets include either five reeds or eight reeds, depending on the product.

Common features include automatic safety shut-off (for low water or empty tanks), sleep-mode or dimmable lighting, intermittent/timed mist settings, and controls such as a remote or an AC power adapter.

The listings show two main types: ultrasonic (electric) diffusers and passive reed diffusers.

Coverage claims range roughly from 160 square feet for compact units up to about 300 square feet for larger ultrasonic models.

Product details recommend spot cleaning or wiping. Reviews and listings also advise regular cleaning to prevent musty smells—wipe the tank and air-dry between uses and follow any manufacturer instructions.
