FAQs

What is the difference between CPAP, APAP, and BiPAP machines?

CPAP (Continuous Positive Airway Pressure) delivers one fixed pressure throughout the night.

APAP (Auto-Adjusting Positive Airway Pressure) automatically adjusts pressure based on your breathing patterns.

BiPAP (Bilevel Positive Airway Pressure) provides two pressure settings: a higher pressure for inhalation and a lower pressure for exhalation.

APAP and Auto-BiPAP devices are often recommended for patients who need more personalized pressure adjustments or have difficulty tolerating fixed CPAP pressure.

Do I need a prescription to purchase a CPAP or BiPAP machine?

Yes. CPAP, APAP, and BiPAP devices are FDA-regulated medical devices in the United States and require a valid prescription from a licensed healthcare provider.

Your prescription will typically specify:

  • Pressure settings (or Auto mode approval)
  • Device type (CPAP, APAP, or BiPAP)
  • Humidifier inclusion (if needed)
How often should I replace CPAP supplies like tubing, filters, and water chambers?

Replacement schedules may vary by manufacturer and insurance provider, but general guidelines are:

  • Disposable filters: Every 2–4 weeks
  • Reusable filters: Every 6 months
  • Standard tubing: Every 3 months
  • Heated tubing: Every 3 months
  • Water chamber: Every 6 months
  • Mask cushions/pillows: Every 1–3 months

Regular replacement ensures optimal airflow, hygiene, and therapy effectiveness.

What is heated tubing and do I need it?

Heated tubing helps maintain consistent air temperature and reduces condensation (“rainout”) inside the tube.

It is especially helpful if:

  • You use a humidifier
  • You sleep in a cool room
  • You experience water buildup in your tubing

Most modern CPAP and BiPAP machines support integrated heated tubing for improved comfort.

Can I travel with my CPAP or BiPAP machine?

Yes. CPAP and BiPAP machines are FAA-approved for air travel and can be carried on airplanes as medical devices.

Most devices:

  • Support universal power supplies (100–240V)
  • Have compact travel bags
  • Offer optional battery packs for off-grid use

It is recommended to bring a copy of your prescription when traveling internationally.

How do I clean and maintain my CPAP machine?

To maintain hygiene and performance:

Daily:

  • Empty and air-dry the humidifier chamber
  • Wipe mask cushion

Weekly:

  • Wash tubing and mask with warm water and mild soap
  • Rinse thoroughly and air dry
  • Clean reusable filters if applicable

Always use distilled water in the humidifier (unless manufacturer states otherwise) to prevent mineral buildup.
