CPAP Equipment and Accessories
The machine matters less than whether you can live with the setup. These guides cover what each piece does and how to make it comfortable enough to use every night.
Most people quit CPAP over the equipment, not the diagnosis. A mask that leaks, a hose that tugs, a cushion that has quietly stopped sealing: small annoyances add up until the machine ends up in a closet. The goal of this section is to get you past those friction points.
We focus on the parts you actually interact with. The prescription machine itself is set by your clinician, but the masks, cushions, filters, and comfort accessories are where day-to-day success is won or lost, and most of those you can adjust yourself.
Prescription rules differ by country. In the United States, CPAP machines require a prescription while most accessories do not. In Canada, machines generally require a prescription too, but accessory purchase rules and provincial funding vary by province, insurer, and supplier.

Frequently asked questions
Do I need a prescription for CPAP equipment in the United States?
In the United States, CPAP and BiPAP machines are FDA-regulated devices that require a prescription. Accessories like masks, cushions, filters, tubing, and cleaning supplies are generally sold without one, though you still need to know your pressure settings and the right mask size for comfort and fit.
Do I need a prescription for CPAP equipment in Canada?
In Canada, CPAP and BiPAP machines generally require a prescription from a doctor or sleep clinician. Accessories such as masks, cushions, tubing, and filters are often sold without one, but some suppliers may still ask for a prescription or proof of your settings. Coverage rules can also vary by province and insurance plan.
Can I buy CPAP masks and supplies without a prescription?
Often yes, in both the U.S. and Canada. Many stores and online retailers sell masks, cushions, filters, and cleaning supplies without a prescription. However, some vendors may still require one for certain items or to process insurance claims.
What CPAP supplies need replacing, and how often?
Replacement schedules depend on the item and your usage, but common guidelines are: - Mask cushion: every 1–2 months - Headgear: every 6–12 months - Tubing: every 3–6 months - Filters: disposable filters monthly; reusable filters every 2 weeks (or as directed) - Cushion/nasal pillow: replace when it no longer seals well or feels stiff Your clinician or supplier may give you a schedule tailored to your machine and wear patterns.
Where should a beginner start?
If you're new to CPAP: - Confirm your diagnosis and pressure settings with your clinician. - Pick a mask type that fits your breathing style (nasal, pillow, or full-face). - Start with basic accessories: mask, cushion, tubing, and a filter. - Add comfort items only if needed (humidifier, hose lift, cushion pad, chin strap). - Focus on consistency: a setup you can tolerate every night is better than a "perfect" one you abandon.
Does my province pay for CPAP equipment in Canada?
Sometimes. Provincial funding for CPAP equipment varies across Canada. Some provinces offer public support for eligible people (for example, through programs like Ontario's Assistive Devices Program), while others rely mainly on private insurance or special assistance programs. Coverage is not the same as purchase permission, so it's best to treat these as two separate questions: whether you need a prescription and whether you get help paying for it.
What is the difference between CPAP and BiPAP?
CPAP delivers a single, continuous pressure for both inhaling and exhaling. BiPAP (bilevel positive airway pressure) delivers two pressures: a higher one for inhaling and a lower one for exhaling, which some people find easier to breathe against. Your clinician will decide which type matches your needs.
Can I use CPAP or BiPAP without a sleep study?
Technically, you should have a diagnosis and prescription before starting CPAP or BiPAP therapy. In both the U.S. and Canada, machines are prescription devices, and using them without proper evaluation can lead to incorrect settings or missed health issues.
