if it is respirator you are talking about then it is not as fun as you think
. you need a good seal between your face and the respirator in order to be
effective. in hot days you will sweat pretty fast with the mask on and the
seal will compromise. people usually go thru medical clearance, breathing
test and face fit before wearing that kind of mask. it might as well be
better stick two cottons in the nose.
