Please recommend an office diffuser for the summer.

Maybe because the office is in an old building, a musty smell from the humidity would creep up every summer.

I would appreciate it if you could recommend a diffuser with a refreshing scent that isn't heavy.

It would be even better if it were a large-capacity, affordable diffuser haha.

Since it's for the office, I figured it would be fine as long as it's a bit affordable and the scent lasts... haha
