| We all love chilled air, itâs clean and refreshing. BUTâ¦. cold air in you lungs on a constant basis causes all sorts of issues from reduced lung function to inducing asthma attacks. Not good! If you love the chill in the air on a crisp sunny morning but hate that cold chill in your lungs on the slopes, or suffer from exercise induced asthma, exacerbated by cold air, a Respro® Mask could allow you to breathe easier. The mask will act as a heat exchanger, warming the air retained from the breath cycle before. In short, it will warm up the cold air before it enters the lungs.
The SPORTS FILTER with POWA⢠ELITE VALVES is the perfect combination for elevated breathing rates. I would describe it using the following parallel. A bald man uses a wooly hat in cold weather to keep his head warm. He will soon notice the cold weather when he takes his hat off. Same with the mask and the air going into your lungs. |
