You've been prescribed a BiPAP or CPAP machine. Your pressure settings are sorted. The machine is on your bedside table.
Then your provider asks: Which mask would you like?
For most new patients, this question lands completely cold. Nobody warned you there were multiple mask types. Nobody explained that the mask you choose affects your comfort, your likelihood of sticking with therapy, and even whether aerophagia or dry mouth becomes a problem.
The wrong mask choice is one of the top reasons patients abandon PAP therapy in the first 90 days — not because the therapy isn't working, but because the mask feels claustrophobic, leaks, leaves pressure marks, or makes breathing feel unnatural.
This guide covers everything you need to know to choose the right mask: how each type works, who it suits, what the trade-offs are, and how to tell from your own sleeping habits and anatomy which one is most likely to work for you.
All PAP masks do the same fundamental job: they deliver pressurised air from your machine to your airway and maintain a seal so that pressure isn't lost through leaks. But they accomplish this in three fundamentally different ways.
Mask Type | Covers | Best For | Avoid If |
Nose + mouth | Mouth breathers, high-pressure therapy, and nasal congestion | Claustrophobia, active sleepers, lower pressure prescriptions | |
Nose only (triangle over nose) | Side sleepers, moderate pressure therapy, and most general users | Mouth breathers (without a chin strap), nasal congestion | |
Nostrils only (two soft inserts) | Active sleepers, claustrophobic patients, glasses wearers, and high-pressure tolerance | Severe nasal congestion, very sensitive nasal passages |
There are also oral masks (mouth only) and hybrid masks (nasal pillows + mouth coverage) — but these are less common in standard home BiPAP use and won't be covered in detail here.
Full Face Masks: The Widest Coverage, the Most Caveats
How Full Face Masks Work
A full face mask covers both your nose and your mouth, creating a single sealed chamber over the lower half of your face. Air from your BiPAP is delivered into this chamber and enters your airway through whichever route is open — nose, mouth, or both.
A silicone or memory foam cushion sits against your skin along the bridge of your nose, your cheekbones, and your chin. Headgear straps hold the mask in position. Most modern full-face masks have a forehead support bracket to reduce pressure on the nose bridge.
Who Full Face Masks Are For
Mouth breathers — this is the primary indication. If you breathe through your mouth during sleep (either by habit or because of nasal congestion), a nasal or pillow mask will create immediate problems: air delivered through the nose leaks out through the open mouth, the machine detects the pressure drop and increases output, and you end up with uncomfortable air gusts, dry mouth, and interrupted sleep. A full face mask eliminates this problem entirely by sealing both entry points.
Patients with chronic nasal congestion — blocked sinuses, nasal polyps, deviated septum, or severe seasonal allergies all force mouth breathing at night. A full face mask is the practical choice until the congestion is actively treated.
High-pressure prescriptions — at IPAP settings above 15 cmH₂O, maintaining a nasal mask seal against the higher pressure requires a near-perfect fit. Full face masks distribute the force over a larger contact area, making a reliable seal more achievable.
Patients who've tried nasal masks and experienced chronic leaking — sometimes anatomy (nose shape, facial structure) makes nasal mask sealing genuinely difficult. A full face mask is the pragmatic alternative.
The Real Trade-offs of Full Face Masks
Claustrophobia — the most common complaint. A full face mask covers a significant portion of the face. For patients who are already anxious about PAP therapy, the full face mask can feel suffocating or overwhelming. This is not a minor comfort preference — claustrophobia-related panic is a real PAP abandonment driver.
Aerophagia risk — as covered in our aerophagia article: full face masks cover both mouth and nose, and air delivered to the oral cavity has a shorter, more direct path to the oesophagus than air delivered through the nose. Patients on high-pressure full face masks have higher aerophagia rates than nasal or pillow mask users.
Sleeping position restrictions — full face masks are bulky. Side sleeping is manageable, but you'll feel the mask edge pressing into the pillow. Stomach sleeping is essentially impossible. Some patients use CPAP-specific pillows with cut-outs to accommodate the mask.
Leak sites — the large contact area is also a large potential leak area. Nose bridge leaks (air blowing into eyes) are common with an improper fit. The chin seal is another frequent failure point. Getting a reliable seal on a full face mask often takes longer and requires more mask fitting trials.
Skin and pressure marks — the broad silicone contact area can cause redness, pressure marks, and over time, skin breakdown at the nose bridge or cheeks. Using the lowest strap tension that still maintains a seal reduces this. Some patients use thin cloth barrier strips (mask liners) to protect skin.
Condensation and humidity — the larger internal volume of a full face mask means more surface area for moisture to condense. In cold rooms, you may see fogging or feel condensation against your face. A heated humidifier and heated tube combination addresses this.
Popular Full Face Mask Models Available in India
ResMed AirFit F20 — widely regarded as the best-sealing full face mask currently available; magnetic clip release makes it easy to remove; fits a wide range of face shapes
ResMed AirFit F30 — minimal contact design; reduces the amount of silicone against the face without losing the full face seal; good option for patients who find F20 too bulky
Philips Respironics DreamWear Full Face — under-nose cushion design; the seal sits under the nose rather than over the nose bridge, eliminating the nose bridge pressure mark
BMC F5A — affordable full face option compatible with BMC machines; also works with other brands' machines
Nasal Masks: The Versatile Middle Ground
How They Work
A nasal mask covers only the nose, forming a triangular seal from the bridge of the nose down to just above the upper lip. Air is delivered through the nose only. The mouth is not covered.
Because air is directed through the nasal passage rather than directly into an open oral cavity, it travels through more anatomy before reaching the throat — which naturally reduces aerophagia risk compared to a full face mask. The nasal passage also humidifies and warms air slightly, which can reduce dryness.
Who Nasal Masks Are For
Nasal breathers — if you naturally breathe through your nose during sleep, a nasal mask is almost always the first choice. It's the most versatile PAP mask type and suits the widest range of patients.
Side sleepers — nasal masks are lower-profile than full face masks. Side sleeping is comfortable; the mask doesn't press aggressively into the pillow. Many nasal masks have flexible, pivoting elbow connectors that accommodate head movement.
Patients who feel claustrophobic in full face masks — nasal masks cover significantly less of the face. The mouth and chin are completely free. For anxious or claustrophobic patients, this is often the breakthrough mask type.
Active sleepers who move during the night — nasal masks maintain their seal better during positional changes than full face masks. There's less surface area to lose contact with.
Patients requiring high pressure — nasal masks can accommodate high IPAP settings reliably once properly fitted, particularly with newer cushion designs that use pressure to actually improve the seal (the higher the internal pressure, the tighter the cushion presses against the face).
The Real Trade-offs of Nasal Masks
Mouth breathing destroys the seal — if you open your mouth during sleep, pressure escapes immediately. The machine ramps up pressure to compensate. You wake up with a dry, open mouth and disrupted sleep. A chin strap solves this for most patients — a simple elastic band that supports the jaw and keeps the mouth gently closed. It's not uncomfortable for most users and becomes invisible after a week or two of use.
Nose bridge fit is critical — the nose bridge of a nasal mask is the most common leak point. Noses vary enormously in shape: wide bridges, narrow bridges, prominent bridges, flat bridges. Most mask brands offer multiple cushion sizes (small, medium, large) and some offer additional cushion shapes (standard, wide). Getting the right size is more important than getting the "right" brand. A mask fitting session with a clinician is valuable here.
Nasal congestion makes it difficult — if your nose is blocked, a nasal mask becomes ineffective. You need to breathe through your mouth, which defeats the purpose and creates leaks. Addressing congestion (humidifier, saline rinse, nasal spray) is necessary before nasal masks work well.
Air may blow into eyes — a common complaint, particularly during the break-in period. Usually caused by nose bridge leaks. Adjusting the fit — loosening the forehead strap, repositioning the mask slightly — typically resolves this.

Nasal Pillow Masks: Minimal, Direct, and Surprisingly Effective
How They Work
Nasal pillow masks are the most minimal PAP interface available. Instead of a mask frame that covers the nose, two small soft silicone inserts — the "pillows" — fit directly into the nostrils. Air is delivered directly into the nasal passages. There is no facial contact other than the pillow inserts and the light headgear frame.
Who Nasal Pillow Masks Are For
Claustrophobic patients — nasal pillows have the smallest facial footprint of any mask type. If a full face mask felt like suffocation and a nasal mask still felt confining, nasal pillows often work when nothing else does. Patients who've abandoned PAP therapy due to mask claustrophobia frequently return successfully with nasal pillows.
Glasses wearers or readers who use their machine while awake — the open face design doesn't interfere with glasses at all.Patients who like to read or watch TV while the machine warms up can do so without impediment.
Active sleepers who move frequently — the minimal headgear is flexible and stays in position across a wide range of sleeping positions. Some nasal pillow systems have tubing that connects at the top of the head, reducing hose drag entirely. Facial hair — beards and significant facial hair make it very difficult to achieve a reliable seal with nasal or full face masks (cushions need smooth skin contact). Nasal pillows only contact the nostrils — facial hair has no impact on the seal.
High-pressure users who experience nasal bridge pain from nasal masks — some patients at high IPAP are comfortable with the direct nasal pillow delivery despite the pressure; others find it uncomfortable. Individual trial determines this.
Patients who find mask cleaning burdensome — nasal pillow masks have the least surface area to clean. The pillows and minimal frame take 2 minutes to wash. For patients who struggle with mask hygiene compliance, the simplicity of nasal helps.
The Real Trade-offs of Nasal Pillow Masks
Nostril irritation and dryness — air is delivered directly into the nostrils at whatever pressure and humidity your machine outputs. Without adequate humidification, this causes dryness, soreness, and sometimes nosebleeds. A heated humidifier is essentially mandatory with nasal pillows — not optional. At the correct humidity setting, this is usually not an issue.
Pressure limits — at very high IPAP settings (roughly above 15–16 cmH₂O), the direct air delivery of nasal pillows can feel blasting and uncomfortable. The sensation of high-pressure air directly in the nostrils is qualitatively different from air entering through the broader nasal mask chamber. Most patients with moderate prescriptions don't encounter this limit; those at high pressures sometimes need to switch to a nasal mask.
Mouth breathing — same problem as nasal masks. Mouth opening defeats the therapy. A chin strap is needed for mouth breathers with nasal pillows.
Wrong pillow size = poor seal + discomfort — nasal pillow sizing is critical. Pillows that are too small leak around the edges; pillows that are too large cause nostril discomfort and pain. Most systems come with multiple pillow sizes. Trying all sizes methodically (starting with the smallest that seals, not the largest that fits) is the right approach.
Not suitable for severe congestion — same limitation as nasal masks. If you can't breathe through your nose, air has nowhere to go except back out or into your mouth. This creates noisy leaks, pressure compensation by the machine, and disrupted sleep.

Choosing the Right Mask: A Step-by-Step Decision Guide
Work through these questions in order.
Step 1: Are You a Mouth Breather?
How to know: Do you wake up with a dry, stale mouth in the morning (even before starting PAP therapy)? Does your partner say you breathe with your mouth open during sleep? Do you have chronic nasal congestion, a deviated septum, or nasal polyps?
Yes, confirmed mouth breather → Start with a full face mask
Sometimes / unsure → Try a nasal mask + chin strap; switch to full face if chin strap doesn't keep mouth closed
No — nasal breather → Proceed to Step 2
Step 2: Do You Have Claustrophobia or Anxiety About Mask Use?
Yes — masks feel suffocating → Start with nasal pillows; if directness feels too harsh, try a minimal nasal mask (AirFit N30 or DreamWear under-nose style)
No → Proceed to Step 3
Step 3: What Is Your Primary Sleeping Position?
Back sleeper → Any mask type works; full face mask is most forgiving for back sleeping
Side sleeper → Nasal mask or nasal pillows preferred; full face mask is workable with a CPAP pillow; avoid full face mask if you press your face into the pillow
Stomach sleeper → Nasal pillows only — the minimal headgear and front-of-face absence make stomach sleeping possible, though not ideal for PAP therapy in general
Step 4: What Is Your Prescribed Pressure Range?
Low to moderate (IPAP 6–14 cmH₂O) → All mask types can work
Moderate to high (IPAP 14–18 cmH₂O) → Nasal mask or full face mask preferred; nasal pillows may feel uncomfortable at this range
High (IPAP above 18 cmH₂O) → Full face mask or nasal mask; nasal pillows are typically not comfortable at this pressure
Step 5: Do You Have Facial Hair?
Beard or significant stubble → Nasal pillows are the most reliable option; full face and nasal masks struggle to seal against hair
Clean-shaven or minimal facial hair → Any mask type is viable
Step 6: Is Aerophagia a Known Issue For You?
Yes — you've had aerophagia problems → Avoid full face mask if possible; prioritise nasal mask or nasal pillows, which route air through nasal anatomy and reduce stomach air entry
No known aerophagia → Any type works
Mask Fitting: Why Size Matters as Much as Type
Choosing the right mask type is only half the equation. The wrong size within a correct mask type is just as problematic as the wrong type entirely.
Standard sizing across most brands: XS, S, M, L (some brands add SW — Small Wide, or MW — Medium Wide)
How to size yourself:
Most mask brands provide paper sizing gauges — templates you print and hold against your face to identify the right size. ResMed provides sizing gauges downloadable from their website. If you're buying from a physical provider, ask for a fitting session.
General guidelines:
Start with medium — it fits the majority of adults
If you have a narrow or smaller face, try small; if wide, try large
The nose bridge of a nasal mask should sit naturally on the nose without pressing the tip of the nose flat
The bottom of a full face mask cushion should sit just above the chin, not pressing into it
Nasal pillow inserts should fit snugly without flaring the nostrils open — if the pillows are visibly widening your nostrils, they're too large
Cushion pressure: When wearing your mask and starting the machine, the cushion should inflate slightly with air pressure and settle into a comfortable seal. If you can hear air escaping, the seal is broken. If you feel pain, it's too tight. The sweet spot is a secure seal at the lowest strap tension that achieves it — most people overtighten, which causes skin marks without improving the seal.
Common Mask Problems and How to Fix Them
Problem: Air blowing into my eyes
Cause: Nose bridge leak — the top of the nasal or full face mask isn't sealing against the nose bridge properly.
Fix: Loosen the forehead strap (counterintuitively, tightening it often makes this worse by lifting the cushion off the lower face). Try a smaller cushion size. Consider switching to an under-nose nasal mask style (AirFit N30, DreamWear) that eliminates nose bridge contact entirely.
Problem: Red marks or sores on my nose or face
Cause: Mask is too tight, or cushion size isn't right for your face shape.
Fix: Loosen straps. Use mask liners (thin cloth barriers between silicone and skin — Pad-A-Cheek and similar brands make these). Try a different cushion size. Consider a mask type with less facial contact (nasal pillows have the least).
Problem: My mouth keeps falling open / dry mouth in the morning
Cause: Mouth breathing during sleep, defeating nasal or pillow mask therapy.
Fix: Add a chin strap. This is simple, inexpensive, and effective for the majority of mouth-breathing nasal mask users. If the chin strap doesn't fully solve the problem, switch to a full face mask.
Problem: Air leaking around the chin (full face mask)
Cause: The chin seal of the full face mask isn't maintaining contact — either the mask is the wrong size, or your jaw relaxes and drops during deep sleep more than the mask accommodates.
Fix: Try a larger cushion size. Adjust the lower straps. Consider a different full face mask model — some have more flexible chin sections than others.
Problem: Mask feels claustrophobic / I panic when I put it on
Cause: This is a genuine psychological response, not a character flaw. It's common, especially in new PAP users.
Fix: Start with wearing the mask while awake and not connected to the machine — just wearing it while watching TV to desensitise. Then connect it and run the machine while awake. Only use it for sleep once you feel comfortable wearing it at rest. Switch to a more minimal mask type — nasal pillows have the lowest claustrophobia rate. Some patients benefit from speaking to their doctor about short-term anxiety support during PAP initiation.
Problem: Noisy air leaks waking me or my partner
Cause: Mask isn't sealing properly — air escapes through the cushion gap and creates noise. Distinct from the intentional exhaust venting ports all PAP masks have.
Fix: Re-fit the mask with the machine running (always fit under pressure, never dry). Clean the cushion — skin oils degrade silicone sealing over time. Replace the cushion if it's past its replacement schedule. Ensure correct size.
Problem: Nasal pillow inserts feel uncomfortable / sore in nostrils
Cause: Pillow inserts are too large, or inadequate humidification is causing nasal dryness.
Fix: Try one size smaller in the pillow inserts. Increase humidifier setting. Use a saline nasal spray before bed to pre-moisturise the nasal passages.
Mask Hygiene: The Schedule Most Patients Ignore
Mask hygiene is not optional. Skin oils, moisture, and respiratory bacteria accumulate in PAP masks rapidly. A dirty mask degrades faster, seals worse, and can become a source of infection.
Component | Cleaning Frequency | How |
Cushion / Pillow inserts | Daily | Warm water + mild liquid soap; rinse thoroughly; air dry away from sunlight |
Mask frame | Weekly | Same as cushion; check all crevices for buildup |
Headgear | Weekly | Hand wash in mild detergent; do not machine wash; air dry |
Tubing | Weekly | Fill with warm soapy water; swirl; rinse; hang vertically to dry |
Humidifier chamber | Daily rinse, weekly wash | Daily rinse with water; weekly wash with mild soap or white vinegar solution |
Component | Replace Every |
Cushion / pillow inserts | 1–3 months |
Mask frame | 6 months |
Headgear | 6 months |
Tubing | 3–6 months |
Humidifier chamber | 6 months |
Filters (disposable) | 2–4 weeks |
Filters (reusable foam) | Monthly wash; replace every 6 months |
These schedules seem aggressive, but silicone degrades with repeated washing and skin oil exposure. A cushion past its replacement date seals poorly — and a leaking mask means your therapy isn't working properly.
Frequently Asked Questions
Q: Can I use any mask brand with my BiPAP machine?
In most cases, yes. PAP masks use a standard 22mm connector that fits all major machine brands. A ResMed mask will connect to a BMC or Philips machine and vice versa. The exception is certain proprietary connectors — check your machine's manual if in doubt. The machine and mask manufacturers are separate decisions.
Q: I keep leaking no matter what I try. What am I doing wrong?
Persistent leaking despite multiple fitting attempts usually means one of: wrong mask type for your breathing pattern, wrong cushion size, cushion past its replacement date, fitting without the machine running (always fit under pressure), or an anatomical challenge that needs a mask fitting specialist. Request a formal mask fitting session — this service is valuable and under-used.
Q: Is it normal for the mask to make noise?
A certain amount of exhaust noise is normal — all PAP masks have venting holes that release exhaled air, and this creates a gentle whooshing sound. This is intentional. Sputtering, squealing, or hissing noises indicate a cushion leak that needs addressing.
Q: How do I know when to replace my cushion?
Signs a cushion needs replacing: the silicone feels tacky or has discoloured; you're experiencing more leaks than usual despite proper fit and clean surfaces; you can see tears, flattening, or deformation in the silicone. When in doubt, replace — cushions are the cheapest component of the system.
Q: My child needs BiPAP. Do standard adult masks fit?
No — paediatric PAP masks are a separate product category designed for smaller facial dimensions. If your child has been prescribed BiPAP, ask your prescribing hospital or sleep specialist about paediatric mask options. Do not use adult masks on children.
Q: Can I try a mask before committing to one type?
Yes, and you should. Most reputable BiPAP providers can facilitate a trial or offer mask fitting guidance. At Healthy Jeena Sikho, we can help you identify the right mask type based on your prescription and sleeping habits.
