Frequently Asked Questions   How does the BreathXchange Mask work? The BreathXchange mask contains a lightweight thermal conversion module that captures the vapor that is typically expended in the normal course of breathing.   The module actually captures warmth when you exhale.  As you inhale the cold air, the module gently warms the air returning heat into your body.  This advanced technology allows you to constantly breath in fresh warm air while trapping moisture to keep your mask drier.  The BreathXchange masks keeps your core body temperature warm when you're facing extremely frigid outdoor elements.   Who may benefit from a BreathXchange mask?   Breathing cold air bothers many people. If you have noticed that breathing cold air bothers you, then you will benefit from the mask. Participants in cool or cold weather sports who notice that the cold bothers them when they exercise will benefit. Players on the side lines will stay warm while not exercising. Spectators of cold weather sports (such as football) will find that not only will they breathe better, but they will stay warmer wearing a mask. Anyone who works outdoors in cold weather will benefit.   I've seen other cold weather and "heat exchange" face masks. Why is BreathXchange better? Personal Respiratory Heat Exchange (PRHE) and "artificial nose" devices have been around since the first patent in 1898.  New technology has has allowed major improvements. BreathXchange masks utilizes a simple lightweight PRHE the QXtec, and  offer the following advantages:   Versatility. The BreathXchange  masks are designed to be effective in many cold weather venues. When the temperature drops below freezing, the mask will warm the air you breathe to room temperature. Quality. Your BreathXchange mask is made of quality materials. The QXtec heat exchanger is made with the highest standards and is thoroughly tested. The entire assembly is durable and machine washable. Breathability. The BreathXchange  mask has the lowest resistance to breathing, of any masks, allowing use while exercising or working. You are breathing in fresh air, not air that you have just breathed out into a "warming" or rebreathing mask like many on the market. Acoustics. Your friends can hear and understand you. Value. The BreathXchange  mask will out perform most other masks and provide many years of use. Guarantee. If you are not satisfied with the quality or performance, return it for a full refund. How is the BreathXchange Mask cleaned? The entire mask and heat exchange module can be machine washed in cold water on the gentle cycle and line dried. The module can be washed hundreds of times without deterioration, or harm. The fabric mask can be machine washed in cold water and line dried. We recommend washing the fabric in cold water to increase the longevity of the fleece. Is the BreathXchange technology patented? Yes. The QXtec technology and the device are patented. BreathXchange is a registered trademark. I have a lung or heart condition and cold air triggers my symptoms. Is this a treatment to prevent symptoms? This is not yet an FDA certified medical device. This is a cold weather product designed to keep you warm and comfortable just like gloves, hats and jackets. This device warms the air you inhale but should not be considered as a treatment that can replace medications for lung, heart or other medical conditions. Consult with your physician regarding the benefits of avoiding breathing cold air. How can I get a BreathXchange mask? Check our "Where to Buy" page for both web and retail stores that sell the masks. Does the BreathXchange  mask require batteries? No! The heat is captured from your exhaled breath. This heat is normally wasted. Does the facemask get  wet and gooey and icy? No. The module captures the water vapor and returns it to the air you breathe. The moisture management is handled by the heat exchanger - not the fleece. Breathing humidified air puts less stress on your body. Is the desiccant safe? Yes! The desiccant is bonded to the plastic and is not inhaled.
