Most BiPAP machines cost between $1,700 and $3,000, though some advanced models run significantly higher. That’s the out-of-pocket price without insurance. What you actually pay depends on whether you buy outright, rent through a supplier, or have insurance covering part of the cost.
Retail Price by Machine Type
A standard BiPAP delivers two pressure levels: one when you breathe in and a lower one when you breathe out. These fixed-pressure models sit at the lower end of the range, typically $1,700 to $2,200. The ResMed AirCurve 11 VAuto, one of the most widely sold auto-adjusting BiPAP models, retails for around $1,796.
Auto-titrating BiPAP machines, which adjust pressure automatically throughout the night based on your breathing patterns, tend to land in the $2,000 to $3,000 range. The most expensive category is adaptive servo-ventilation (ASV) devices, designed for complex or central sleep apnea. These can cost $4,000 or more because they continuously analyze your breathing and respond on a breath-by-breath basis.
For comparison, a standard CPAP machine (which delivers a single constant pressure) typically costs $500 to $1,000. BiPAP machines are more expensive because they use more sophisticated pressure-sensing technology.
Ongoing Supply Costs
The machine itself is the biggest expense, but it’s not the only one. You’ll need to replace masks, filters, tubing, and water chambers on a regular schedule. Masks wear out every three to six months, filters need swapping monthly, and tubing should be replaced a few times a year. These recurring costs add up to roughly $20 to $100 per month depending on the supplies you use and how often you replace them.
Renting vs. Buying
Many durable medical equipment suppliers offer rental programs, and some insurance plans actually require you to start with a rental before the machine becomes yours. Monthly rental rates vary widely based on your location and insurance arrangement, but the general range for PAP therapy runs $20 to $100 or more per month. After a set rental period (often 10 to 13 months), the equipment transfers to you permanently.
Buying outright makes sense if you don’t have insurance or prefer to avoid the rental process. You’ll own the machine immediately, and online retailers often sell at lower prices than brick-and-mortar medical supply stores. The tradeoff is a larger upfront payment.
What Insurance Typically Covers
Most private insurance plans cover BiPAP machines when they’re deemed medically necessary, but the specifics vary. You’ll generally need a sleep study showing your condition qualifies, a prescription from your doctor, and documentation that symptoms like excessive daytime sleepiness, morning headaches, or cognitive difficulty are present.
Medicare covers BiPAP devices under specific diagnostic categories. For conditions like neuromuscular disease, severe chest wall abnormalities, central sleep apnea, or hypoventilation syndromes, coverage requires documented lab results and, in many cases, a facility-based sleep study showing the device improves your breathing during sleep. Medicare typically covers 80% of the approved amount after you meet your deductible, leaving you responsible for the remaining 20%. On a $2,000 machine, that’s roughly $400 out of pocket.
Private insurers often follow a similar model, covering 70% to 90% after deductibles. Some plans require prior authorization, meaning your doctor submits paperwork proving the BiPAP is necessary before the insurer agrees to pay. This process can take a few days to several weeks.
The Sleep Study You’ll Need First
Before you can get a BiPAP, you’ll need at least one sleep study, and possibly two. The first study diagnoses your condition. If a BiPAP is prescribed, a second study (called a titration study) calibrates the machine’s pressure settings while you sleep in the lab. The average cost of an in-lab sleep study is around $3,000, with prices ranging from $1,000 to over $10,000 depending on the facility and your insurance.
A split-night study combines both steps into a single visit: the first half diagnoses the problem, and the second half calibrates the device. This approach saves you a second night in the lab and can cut the total cost of testing roughly in half. Not everyone qualifies for a split-night study, but it’s worth asking your sleep specialist about.
Ways to Reduce the Total Cost
If the sticker price feels steep, a few strategies can help. Online retailers frequently sell BiPAP machines at 20% to 40% below what local medical equipment stores charge, though you may lose access to in-person setup support. Some manufacturers and third-party companies offer financing plans that break the cost into monthly payments, often interest-free for the first 6 to 12 months.
Refurbished machines from reputable sellers offer another option. These are typically returned or lightly used units that have been cleaned, tested, and repackaged. Prices on refurbished BiPAPs can be $500 to $1,000 less than new models, though warranty coverage is usually shorter. If you go this route, make sure the seller is an authorized dealer and that the machine has been properly serviced.
For supplies, buying in bulk or using subscription services from online PAP retailers can bring the monthly cost of replacement parts down noticeably compared to purchasing through your doctor’s office or a local supplier.
