Every person’s needs are different. If you’re unsure, reach out to our team — we’ve helped thousands of customers find the right setup for their prescription, comfort, and breathing style. We can match your device, mask type, and pressure settings so you get the best results.
Do I need a prescription to buy a CPAP or BiPAP machine?
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?
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.
What’s the difference between portable and stationary?
What’s the difference between portable and stationary?
Portable concentrators are lightweight and battery-powered — great for travel or daily outings. Stationary concentrators plug in and deliver continuous oxygen, ideal for home use.
