Transcend Micro Accessories

This collection has the accessories and replacement parts for the Transcend Micro and Transcend Micro 510 travel CPAP machines, from humidification and filters to tubing, batteries and power, travel cases, cables, and resupply packs. Some consumables differ between the two models, so pick the part that matches your machine. Transcend Micro accessories are generally FSA/HSA eligible.

Transcend Micro accessories by type

  • Humidification (AirMist HME): waterless heat-and-moisture exchange, so there is no tank and no distilled water to carry. Shop the AirMist HME adapter and replacement HME cartridges.
  • Filters: the original Micro uses washable PureFresh foam filters; the Micro 510 uses a woven filter with a hypoallergenic option. Choose filters by model.
  • Hoses and tubing: a lightweight travel hose (AirFlex on the original Micro, TransFlex on the Micro 510) plus the WhisperSoft muffler kit for quieter nights.
  • Batteries and power: the PowerAway battery for off-grid nights and a solar charging option for longer trips.
  • Travel cases and bags: the SleepPak bag, a hard shell case, and a travel pouch.
  • Cables and adapters: power cords, DC and USB-C cables, and international travel adapters.
  • Resupply and essentials packs: bundles of the common replacement parts for routine resupply.

Which Transcend Micro do you have?

The Micro and Micro 510 share several accessories, including the AirMist HME, batteries, and travel cases, but they use different filters and hoses, so match those consumables to your model. Not sure which you own, or weighing the upgrade? Read the Micro 510 guide, the Transcend Micro review, or the AirMini vs Micro comparison. Need the machine itself? See the Transcend Micro and Transcend Micro 510, or browse all travel CPAP machines.

FAQs

What accessories does the Transcend Micro need?

The core resupply items are filters, the AirMist HME cartridge for waterless humidification, and the hose. Many users also add a PowerAway battery for travel, a muffler kit for quieter nights, and a travel case. Resupply and essentials packs bundle the common replacement parts together.

Are Transcend Micro and Micro 510 accessories the same?

Some are shared, including the AirMist HME, batteries, and travel cases, but the filters and hoses differ. The original Micro uses PureFresh foam filters and the AirFlex hose, while the Micro 510 uses a woven filter (with a hypoallergenic option) and the TransFlex hose. Match filters and tubing to your specific model.

How often should I replace the AirMist HME and the filter?

The AirMist HME cartridge is a regularly replaced consumable, so keep a fresh supply on hand. The PureFresh foam filters on the original Micro are washable, so rinse them regularly and replace them periodically. Follow the schedule in your Transcend Micro user manual rather than a fixed number, since intervals vary.

Does the Transcend Micro need distilled water?

No. The Transcend Micro uses AirMist HME (heat-and-moisture exchange), a waterless humidification method, so there is no water chamber and no distilled water to carry. You replace the small HME cartridge instead of filling a tank, which is part of what keeps it travel-friendly.

What battery and charging options are there for the Transcend Micro?

The PowerAway battery adds extended off-grid run time and is used with the machine's own power supply. A solar charging option is available for longer trips off the grid, and international travelers can add plug and travel adapters for overseas outlets.

Do I need a prescription to buy Transcend Micro accessories?

Accessories and replacement parts such as filters, hoses, HME cartridges, batteries, and cases are not prescription items the way the CPAP machine itself is. If you still need the machine, see the Transcend Micro travel CPAP machine pages.
