I am recovering from a cold so have a bad cough which is worse at night when sleeping with the air conditioning on. I would wake up every 2 hours to drink water, go to the bathroom and cough. With this mask, I can sleep through the night without feeling the need to keep drinking water at night. Very lightweight and comfortable, easy to use too.
recently my daughter caught cold, so need to wear mask in school. Purchased this for her hoping to reduce the discomfort when caugh.
Better that what I expected!
Not cheap, but definitely more comfortable compare with regular mask.
Bought this for my kid when going to clinic or hospital, mask is moist and very comfortable to wear on.
