The AsterOutdoor 500ml is an ultrasonic diffuser and cool-mist humidifier with a 16.91 oz tank, a remote control, a timer and seven color lights. It runs 12–16 hours on low mist and 6–8 hours on high, and it ships with six fragrance oils. The PP plastic body is the same food-grade type used for baby bottles, and auto shut-off cuts the mist when the water runs out. It suits bedrooms, offices and yoga rooms where you want scent and a little humidity from one unit. Against smaller 100–300ml diffusers it lasts longer between refills, but it is bulkier and the remote is the main convenience over basic dial models.

The body is made of non-corrosive polypropylene (PP) plastic. One filling runs 12-16 hours on low mist and 6-8 hours on high. The diffuser shuts off automatically.
Intermittent mode diffuses every 10 minutes, and continuous mode runs constantly. The LED lights change through multiple colors.
