Does a Diffuser Work as a Humidifier? ASAKUKI 500 ml Diffuser
Worth it, with a clear limit

Worth it or skip it?
Worth it if
- You want an essential-oil diffuser that can also release water mist in a suitable room.
Skip it if
- You need to maintain a specific relative-humidity level.
Key facts
Water-tank capacityIt supplies water for the ultrasonic diffuser, but no output rate or room-size rating is provided.
A diffuser first, humidifier second
Choose it when aromatherapy and some water mist suit your bedroom, office, yoga room, or similar space. If maintaining a specific relative-humidity level is the main goal, a dedicated humidifier is the clearer fit.
Buy on AmazonA little mist with the ritual
On a bedroom desk or yoga-room shelf, the ASAKUKI sends a visible water mist into the air while its diffuser settings run.
What the controls can—and cannot—tell you
Its 500 ml tank and ultrasonic mist modes let it release water mist, with 60-, 120-, 180-minute, intermittent, and steady-ON controls listed by the seller. That supports some humidifying alongside aromatherapy, but no output rate, room-size rating, or humidity control is supplied.
Think of it as an aromatherapy diffuser that can add mist—not a device sized around a humidity target.
