If you are a CPAP user in need of significant humidity, then heated tubing may be a great idea for you. This heated tubing allows you to add a great amount of humidity to the air that you are breathing on your Luna G3 without the consequences. In most cases when you add too much humidity to a standard CPAP tube, you will see excess condensation or rainout in your tube. In some cases, it may even make it all the way through to your face or nose. That is because as the air cools on its way from your CPAP to you, the water vapor condenses and literally rains inside your tube. Not a great CPAP experience. Thankfully, heated tubing is now an option on your Luna G3 CPAP device. The heated tube will control the climate from the humidifier on your CPAP all the way to you. Keeping the maximum amount of humidity possible, so that you are comfortable.
