When we have a breathing situation going on, this wireless portable nebuliser type diffuser is a life saver! On a full charge, it runs for 4 nights and has a continuous diffusing mode and an intermittent diffusing mode.
I’ve perched it in the crevice of a bunk bed during holidays, at the dining table and in funky smelling toilets when I need to. Definitely going with me in my USA convention trip!
