The Resupply Pack contains a WhisperSoft Muffler Kit, a 4' AirFlex Hose, two PureFresh Filters, and an AirMist HME 4 Pack with adapter. These are the parts that see the most wear on a Transcend Micro 510 and the ones that affect sleep quality most directly when they're past their prime.

Filters and the muffler should be swapped every three months. The AirFlex hose is short enough to pack anywhere and flexible enough that it doesn't pull or kink during the night. The AirMist HME cartridges work by capturing moisture from your exhaled breath and returning it on the inhale, which keeps your airway from drying out without requiring a separate humidifier or water tank.

Buying these pieces together costs less than buying them individually, and it means the next resupply is already handled before you need it.

This pack does not include the machine or a mask.
