The Transcend AirMist HME (Heat Moisture Exchanger) is a compact, waterless humidification solution designed for Transcend Micro CPAP users. Instead of requiring distilled water or a bulky humidifier chamber, the AirMist captures exhaled heat and moisture and returns it with each breath, helping to reduce dryness and irritation during sleep therapy. This pack includes everything you need to start using waterless humidification with your Transcend Micro. The adapter connects directly to your CPAP tubing, while the replaceable cartridges provide a week of therapy comfort. Lightweight and travel-friendly, the AirMist system makes it easy to enjoy humidification wherever you go—without the hassle of packing water. SKU: 505009
