This bundle pairs the Transcend Micro 510 travel CPAP machine with the Fisher and Paykel Vitera full face mask, so you get a complete auto CPAP setup in one box instead of ordering the machine and mask as two separate purchases. It is built for anyone who breathes through the mouth at night, deals with nasal congestion, or wants a full face seal that still packs down small for travel. The Transcend Micro 510 weighs about 0.48 lb and measures 3.6 x 3.6 x 2.4 in, making it one of the smallest auto CPAP machines we carry. It automatically adjusts pressure between 4 and 20 cm H2O, humidifies with a waterless AirMist cartridge instead of a water chamber, and connects to the MySleepDash app over Bluetooth so you can check your therapy data from your phone. The machine has no built in battery, ships with a hard shell travel case, and is FAA compliant for carry on use. The F&P Vitera covers both your nose and mouth with a silicone RollFit cushion and VentiCool headgear, and the elbow is permanently attached to the frame so there is one less part to lose or reattach. It is magnet-free and sized for adults 66 lb (30 kg) and up, and it carries HCPCS codes A7034 and A7035 for insurance and FSA/HSA documentation. A prescription is required for the Transcend Micro 510, and this bundle qualifies for FSA and HSA spending. If you are still deciding between a nasal mask and a full face mask for travel, our guide to CPAP masks for mouth breathers walks through how to tell which one fits how you actually breathe at night.
