ResMed CPAP Masks: A Procurement Manager’s Side-by-Side Comparison of Nasal vs. Full Face (2025)

If you’re responsible for stocking a sleep center, you’ve probably stared at ResMed’s mask lineup and wondered which ones to buy. Nasal pillows? Full face? Something in between?

I’ve been managing procurement for a mid-sized sleep network for 6 years—eight clinics, about 2,400 patients annually. Over that time, I’ve tracked every mask order in our cost system (circa 2019 through Q1 2025). And I’ve learned one thing: the cheapest mask on the shelf is rarely the cheapest in the long run.

This isn’t a clinical review. It’s a purchasing guide—through the lens of total cost, patient stickiness, and hidden fees. Here’s what I’ve found comparing ResMed’s two most popular mask categories: nasal (including the new ResMed CPAP mask models) vs. full face.

Dimension 1: Upfront Cost vs. Replacement Frequency

Nasal Masks (AirFit P10, N30, N20)

Nasal cushion masks typically cost $89–$149 per unit (based on quotes from three major DME vendors, January 2025). The individual cushions? Around $19–$35 each. On paper, that seems reasonable.

Full Face Masks (AirFit F20, F30, F40)

Full face masks run $119–$189. Replacement cushions are $29–$45.

People think the full face is more expensive because it costs more upfront. Actually—the opposite is true in total cost. Here’s why: full face cushions last 2–3 months on average before the silicone degrades or the seal fails (per our patient return logs, 2024). Nasal cushions? 1–2 months max. Mouth breathers degrade them faster, and if your patient shifts to a mouth-open sleeping pattern—which happens often—the nasal cushion fails even quicker.

Simple: over a 12-month compliance period, a F20 bundle (plus three extra cushions) costs roughly $240. A P10 bundle? $220. The difference: about $20 a year (prices as of March 2025; verify current rates).

Per-patient cost difference is negligible—but the full face mask significantly reduces returns due to air leakage. That’s where real savings live.

Dimension 2: Patient Compliance and the 'Mask Hopper' Factor

Here’s the thing procurement folks rarely calculate: a patient who can’t tolerate their mask costs you money in follow-up visits, equipment swaps, and lost compliance reauthorization.

In Q3 2024, our clinic tracked 47 patients who started with a nasal mask and 52 who started with full face. After 90 days, nasal mask patients had a 21% swap rate (meaning they needed a different mask). Full face: 12%.

The assumption is that nasal masks are more comfortable and therefore more compliant. The reality: comfort is subjective. Many patients—especially new ones—feel claustrophobic with a full face mask. But they also swap from nasal due to mouth leakage or pressure intolerance. The ‘mask hopper’—a patient who tries three masks in two months—costs us an average of $78 in administrative time alone (based on our internal tracking).

One of our therapists told me (unprompted): “For every 10 mask swaps, I lose half a day of clinic time.” She was right—I checked our scheduling system. That’s not priced into the mask invoice, but it’s real cost.

Dimension 3: Inventory Complexity vs. Patient Preference

When I look at our inventory spreadsheet (circa early 2024), I see the tension clearly. Full face masks come in 3 sizes (small, medium, large) plus wide variants. Nasal masks? The P30i alone has 3 cushion sizes, 2 frame sizes, plus headgear variations. Multiply by 4 mask models, and you’ve got 27 SKUs to stock.

That’s a lot of shelf space and forecasting. A 3-month supply for our eight clinics means roughly $12,000 in mask inventory at any time (based on average reorder costs, January 2025).

Given that flexibility, I’ve found that a leaner stock—favoring full face (70%) over nasal (30%)—reduces our out-of-stock incidents by about 15% (compared to 2023 when we carried 50/50). But that’s a trade-off. Some patients really do prefer nasal pillows (I’ve seen it). So we keep the top two nasal models in stock and special-order the rest.

Key takeaway: Full face masks simplify inventory. Nasal masks give patients more options (which helps compliance). It’s a balancing act, but one we’ve learned to manage by tracking what patients actually request.

Dimension 4: Hidden Costs That Shift the Equation

There’s a hidden cost to both mask types that most procurement people miss. It’s not the mask itself—it’s the post-delivery support.

When I compared our Q1 2024 data side by side with Q1 2025 (same clinics, same protocols), I found something surprising: patients who swapped from nasal to full face had fewer follow-up calls. About 10% fewer support interactions in the first month. Why? Full face masks are less sensitive to exact fit (they’ve got more silicone surface area to compensate). Nasal cushions? A millimeter off and the patient feels air blowing in their eyes.

That difference, small as it sounds, translated to an estimated $1,200 in saved staff time across all clinics over the quarter (based on 15-minute call intervals and our call volume records). Not a fortune, but it adds up.

Also: returns. Our return rate for full face masks is 4%. For nasal? 9%. Each returned mask costs us about $15 in restocking and inspection time (ugh).

How to Choose (Procurement Edition)

Choose full face as your default:
If your patient roster skews toward older adults (60+), mouth breathers, or people with high pressure settings (15+ cmH2O), full face masks reduce returns and improve compliance—even if the upfront cost is slightly higher.

Choose nasal as your strategic backup:
Younger patients or those with mild apnea often prefer nasal pillows for comfort. And honestly, they stick with therapy better when they’re comfortable. But order conservatively. Keep the top two models (P10 and N30i) in stock, special-order the rest.

One more thing: When I was starting out (2019), I treated a $200 order of masks as unimportant. Now, those same clinics order $20,000 annually. Small orders aren’t a nuisance—they’re potential. Same logic applies to patients who need a nasal mask today: treat them well, they’ll stay with therapy.
