Do I need a prescription to buy a CPAP or BiPAP machine?
Yes. In the U.S., the FDA requires a prescription for CPAP and BiPAP machines. Masks, tubing, and most accessories can be purchased without one. If you’re unsure what you need, we can help guide you through it.
How often should I replace my mask, tubing, and filters?
How often should I replace my mask, tubing, and filters?
For best performance, replace your mask every 3 months, tubing every 6 months, and filters every 2–4 weeks (or as recommended). This keeps your therapy clean, safe, and effective.

How loud are CPAP and oxygen concentrator machines?
Most modern CPAPs run at around 25–30 decibels — about as quiet as a soft whisper. Oxygen concentrators are slightly louder, but still comfortable for home use, especially when placed a few feet away from the bed.
