When you said the mask work, is this because it makes sound when we breath in? Is that the reason why there are batteries?
I read the other questions, but it's not quite clear for me, sorry about that. ^^'

Hello Myrami, the batteries are used for the Air filter, so that you can breath even you wear it for a long time. It' s a Internal Jet Cycling system. n_n
