Is the PureSpa diffuser good for a bedroom?

Yes. It is quiet, compact and shuts off automatically, which suits overnight use on a nightstand. Its mist is best for a small room.

How often do I need to refill it?

Expect to refill it at least once a day for continuous use, since the tank is small. Running it in intervals stretches a fill further.

Yes. Automatic shut-off stops the unit when the water level gets too low.

Owners describe it as quiet, with a faint water sound. It should not disturb sleep or work.
