Different types of CPAP Masks

Which CPAP Mask Should You Choose?

  • Nasal pillow masks — the lightest, least intrusive option. Best for side sleepers, active sleepers, people with facial hair, and users on low-to-moderate pressure (under ~14 cmH₂O). Shop nasal pillow masks.
  • Nasal masks — the most-prescribed style. Best for nose breathers on moderate-to-high pressure who want a secure seal without covering the mouth. Shop nasal masks.
  • Full face masks — cover both nose and mouth. Best for mouth breathers, people with chronic nasal congestion, and users on high pressure settings. Shop full face masks.
  • Replace your mask cushion every 2–4 weeks and the full mask every 3–6 months to keep therapy effective and hygienic.
  • Not sure if you have sleep apnea? Start with a WatchPAT home sleep test before shopping for equipment.

Why Your CPAP Mask Matters More Than Your Machine

If you've just been prescribed CPAP (Continuous Positive Airway Pressure) therapy for sleep apnea, you're about to make one of the most important decisions of your treatment and it's not which machine to buy. It's which mask.

Every CPAP mask on the market delivers the same therapy: pressurized air that keeps your airway open while you sleep. What separates a mask you'll happily wear for the next 8 hours from one you'll rip off at 2 AM is fit. Studies consistently show that the single biggest reason people abandon CPAP therapy in the first 90 days is mask discomfort, not the machine, not the pressure, not the noise. The mask.

The good news: with over a dozen mainstream mask designs on the Canadian market and three fundamentally different mask styles to choose from, there's almost certainly a mask that will work for you. The challenge is finding it without spending hundreds of dollars on the wrong one first.

This guide walks you through the entire decision. By the end, you'll know:

  • The three main CPAP mask types and how they actually differ
  • Which style matches your sleep style, breathing pattern, and prescribed pressure
  • How to size, fit, and troubleshoot your mask
  • How often to replace your mask and its parts (and what happens if you don't)
  • Where to buy your mask in Canada and why "authorized retailer" matters

The 3 Types of CPAP Masks (and Who Each One Is For)

Almost every CPAP mask on the market falls into one of three categories. Getting the category right is the single most important decision, brand and model are secondary.

1. Nasal Pillow Masks - The Minimalist Choice

Nasal pillow masks are the lightest CPAP interface you can buy. Instead of covering your nose, they use two small silicone "pillows" that sit at the entrance of each nostril, sealing from below rather than around. The headgear is usually just a soft strap or two, and there's almost no material touching your face.

Best for:

  • Side and stomach sleepers, nothing pushes against a pillow
  • Active sleepers who move a lot at night
  • People with facial hair (beards, moustaches) that would break a larger mask's seal
  • People who feel claustrophobic in traditional masks
  • Users with pressure settings under about 14 cmH₂O
  • Anyone who wears glasses in bed to read (nothing blocks your line of sight)


Not ideal if:

  • You breathe primarily through your mouth
  • You have very high prescribed pressure (the direct airflow into the nostrils can feel intense)
  • You get frequent nosebleeds or chronic nasal dryness
  • You have persistent nasal congestion


Popular options on SleepEh.ca:
The ResMed AirFit P10 is our best-selling nasal pillow mask and one of the quietest CPAP interfaces ever made. The Philips DreamWear Silicone Pillow (Fit Pack) is a strong alternative with a unique over-the-head tubing design that keeps hoses out of your face. For higher pressures or side sleepers, the ResMed AirFit P30i puts the tube connection at the top of your head, so you can turn freely without dragging tubing across your pillow.

2. Nasal Masks - The Balanced Default

Nasal masks are the most-prescribed CPAP mask type in North America, and for good reason. They cover the nose (but not the mouth) with a triangular silicone cushion, providing a secure seal that handles a wider pressure range than nasal pillows while staying less intrusive than full face masks.

Best for:

  • People who breathe primarily through their nose
  • Users on moderate-to-high pressure settings (roughly 10–20 cmH₂O)
  • Back and side sleepers
  • Anyone whose sleep clinician isn't sure which style to recommend first, nasal masks are the safe default
  • People who found nasal pillows too "direct" but found full face masks too bulky


Not ideal if:

  • You're a chronic mouth breather (your therapy will leak through your mouth all night)
  • You have frequent nasal congestion, allergies, or a deviated septum
  • You have facial hair that crosses the nose bridge the seal will leak


Popular options on SleepEh.ca:
The ResMed AirFit N20 is the workhorse of the category, its InfinitySeal cushion adapts to most face shapes and handles high pressures without leaking. The Philips DreamWear Nasal (Fit Pack) uses the same low-profile frame as the pillow version, with the tube exiting the top of your head, a game-changer for side sleepers.

3. Full Face Masks - The Complete Seal

Full face masks cover both your nose and your mouth, forming a single sealed cavity for pressurized air. They're bigger than the other two styles, but they solve the single biggest issue nasal masks can't handle: mouth leak. If you open your mouth at any point in the night, a nasal or nasal pillow mask loses its seal and your therapy stops working. A full face mask keeps working.

Best for:

  • Chronic mouth breathers
  • People with chronic nasal congestion, allergies, deviated septum, or frequent sinus issues
  • Users on very high pressure settings (above ~15 cmH₂O)
  • People who've tried a chin strap with a nasal mask and still leak
  • Back sleepers who don't mind facial coverage


Not ideal if:

  • You're claustrophobic, full face masks feel like more mask
  • You're a side or stomach sleeper who buries their face in a pillow
  • You have significant facial hair around your mouth and chin
  • You wear reading glasses in bed, the mask will push against the frame


Popular options on SleepEh.ca:
The ResMed AirFit F20 is the most-prescribed full face mask in Canada. The Fisher & Paykel Vitera uses a floating seal that self-adjusts to your face shape during the night, excellent for people who move around. The Philips DreamWear Full Face is unique, it only touches the mouth, not the nose bridge, making it a great option for people who hate bridge pressure.

How to Choose the Right Mask: A 6-Question Diagnostic

Answer these six questions honestly, and you'll have your answer.

Question 1: How do you breathe when you sleep?

If you wake up with a dry mouth every morning, you're a mouth breather even if you insist you're not. Ask your partner if your mouth is open at night. If yes, start with a full face mask. If you're a confirmed nose breather, either a nasal or nasal pillow mask will work.

Question 2: What sleep position do you use?

  • Side or stomach: Nasal pillows or a "top-of-head hose" mask like the DreamWear or AirFit P30i / N30i minimize interference with your pillow.
  • Back: Any style works, pick based on your other answers.

Question 3: What's your prescribed CPAP pressure?

Check the sticker on your machine or your prescription card:

  • Under 10 cmH₂O: Any style works well. Nasal pillows are often most comfortable.
  • 10–14 cmH₂O: Nasal or nasal pillow masks. Full face if you also mouth-breathe.
  • Above 14 cmH₂O: Nasal or full face masks. Pillow masks can feel like a jet stream at high pressure.
  • Above 18 cmH₂O: Full face is usually best — the larger sealed area handles high pressure more comfortably.

Question 4: Do you have facial hair?

Beards and moustaches break the silicone seal on masks that cover the face. If your beard is bushy, choose a nasal pillow mask, the seal is inside the nostril, so hair doesn't matter. Thin or trimmed beards may still work with nasal or full face masks, especially newer floating-cushion designs like the Fisher & Paykel Vitera.

Question 5: Do you have claustrophobia or wear glasses in bed?

If yes to either, go with a nasal pillow mask. Minimal face contact and clear sight lines make a big difference.

Question 6: Do you have chronic congestion or allergies?

If your nose is blocked most nights, a nasal or nasal pillow mask will force you to mouth-breathe involuntarily, which breaks the seal and wakes you up. Choose a full face mask, and consider adding a heated humidifier to your machine.

CPAP Mask Sizing: Why Fit Beats Everything Else

The right mask type in the wrong size is worse than the wrong mask type in the right size. Every mask manufacturer publishes free sizing templates you can print at home, always use them before ordering.

General sizing tips by mask type:

  • Nasal pillow masks usually come in "Fit Packs" one frame with three or four cushion sizes included. Try them all in the first week. Most people don't wear the size they'd have guessed.
  • Nasal masks use the length and width of your nose to determine size. Measure from the top of the bridge to just below where the nostrils meet the upper lip.
  • Full face masks are sized on the distance from the bridge of your nose to just under your bottom lip.


Two size-related warnings:

  • Bigger is not better. An oversized mask leaks more than a small one because it can't create a consistent seal.
  • Tighter is not better. Overtightening the headgear crushes the silicone cushion out of shape and causes more leaks, not fewer. If you see deep red lines on your face after 20 minutes of wear, your straps are too tight.


SleepEh.ca offers phone consultations with our Canadian sleep specialists at 1-888-998-2538, if you're unsure about sizing, call before you buy. It's free, and it saves you from returning masks (many mask categories are non-returnable once opened for hygiene reasons).

Fitting Your Mask Properly (The First Night Ritual)

A mask can be perfect and still feel terrible on night one if you don't fit it correctly. Follow this sequence every time you put on a new mask or replace a cushion:

  1. Wash your face before bed. Facial oils are the number-one cause of silicone seal failure, clean skin creates a much better seal.
  2. Loosen the headgear before you put the mask on. Slip it over your head with the straps as loose as they'll go, then tighten in small increments.
  3. Position the mask, then turn the machine on. Silicone cushions inflate slightly under pressure and form a better seal when air is flowing. Fitting with the machine off can trick you into overtightening.
  4. Lie down in your sleep position while you fine-tune. A mask that seals when you're sitting up will often leak once you lie on your side. Adjust in the position you'll actually be sleeping in.
  5. Tighten symmetrically. A quarter turn on the left, a quarter turn on the right. Uneven tension is the fastest way to pull a mask off-seal.
  6. Give it 2–3 weeks. Your face literally adapts to the mask, the silicone shape softens to your skin, and your skin toughens where the mask sits. Most people who quit CPAP because of "the mask" quit in the first two weeks.

How to Fix the 5 Most Common CPAP Mask Problems

Problem 1: Air leaks (whooshing sound, dry eyes, blowing on partner)

The most common CPAP complaint. Fixes, in order:

  • Wash your face before bed (facial oil is the top culprit)
  • Check the cushion for splits, tears, or hardening, replace it if it's over 4 weeks old
  • Loosen the straps and re-seat the mask with the machine on
  • Try a smaller cushion size, oversizing is a leading cause of leaks
  • If leaks persist, you may be in the wrong mask category (mouth leakers on a nasal mask, for example, need to switch to full face)

Problem 2: Red marks or pressure sores on your face

  • Your straps are too tight, the goal is snug, not compressed
  • Your mask is too small
  • Add a soft mask liner (fabric layer between mask and skin), sold in the CPAP accessories collection
  • Problem 3: Dry mouth every morning


This means you're mouth-breathing at night, and your therapy is leaking out through your mouth. Solutions:

  • Add a chin strap (cheap, low-effort fix that keeps your mouth closed)
  • Switch to a full face mask
  • Add or upgrade your CPAP's heated humidifier

Problem 4: Nasal congestion, dry nose, or nosebleeds

  • Turn up the heated humidifier on your machine, most Canadian users need higher settings than they think in winter
  • Try a nasal saline spray 15 minutes before bed
  • Consider switching from a nasal pillow mask (direct airflow) to a nasal mask (more diffused airflow)

Problem 5: Claustrophobia and anxiety

  • Practice wearing the mask during the day while watching TV or reading 30 minutes at a time, without the machine running, until it feels neutral
  • Try a nasal pillow mask, which has the smallest footprint
  • Use your machine's ramp feature, it starts at low pressure and gradually builds up as you fall asleep

When to Replace Your Mask and Its Parts

CPAP masks are consumables. Silicone hardens, fabric loses elasticity, and filters clog. Following the manufacturer's replacement schedule isn't overkill, it's what keeps your therapy effective.

Part Replace every Why
Cushion / pillow 2–4 weeks Silicone hardens; seal fails
Headgear 6 months Fabric stretches out; can't hold tension
Mask frame 6 months Plastic fatigue and hygiene
Full mask (all parts) 3–6 months End-of-life for whole system
CPAP tubing 3 months Cracks, biofilm buildup
Machine filter (disposable) 1 month Traps dust, dander, pollen
Machine filter (reusable) 6 months Even washed filters degrade
Humidifier chamber 6 months Mineral buildup, cloudiness


The single most-skipped item on this list is the cushion. Skipping cushion replacements is the #1 reason people say "my mask stopped working" three months in. It didn't stop working, the silicone hardened. A fresh cushion often solves what feels like a mask problem entirely.

To simplify, many SleepEh customers set up a recurring supply order through CPAP Accessories so replacement parts arrive on schedule.

Cleaning Your CPAP Mask (The 60-Second Daily Routine)

  • Every morning: Wipe the cushion with a lint-free cloth and mild, unscented soap. Rinse and let air-dry out of direct sunlight.
  • Every week: Fully submerge the cushion, frame, and headgear in warm water with mild soap. Rinse well. Air-dry. Never machine-wash headgear.
  • Never use: Bleach, alcohol, antibacterial soaps with fragrance, or dishwashers. All of these degrade silicone.
  • Optional: A UV CPAP sanitizer (like the Lumin) sterilizes without water or heat and adds a hygiene layer between deep cleans.

Buying a CPAP Mask in Canada: What to Look For

Not every online CPAP retailer in Canada is an authorized dealer for the brand you're buying from. This matters more than most first-time buyers realize.

Buying from an authorized Canadian retailer means:

  • Your manufacturer's warranty is honoured (ResMed, Philips, and Fisher & Paykel warranties are void on grey-market products)
  • You get genuine parts, not knockoffs
  • Prices are in CAD with no surprise customs fees
  • Returns and defect exchanges are handled locally
  • You have someone Canadian to call when something goes wrong


SleepEh.ca is a Canadian-owned authorized retailer for all major CPAP mask brands, ships free anywhere in Canada on orders over $99, and has real Canadian sleep specialists on the phone during business hours. Our complete Sleep Apnea collection covers every mask, machine, and accessory you'll need.

Not Sure If You Have Sleep Apnea?

If you're reading this without a formal diagnosis, you snore, you wake up tired, your partner says you stop breathing at night, please get tested before buying any equipment. Sleep apnea is a serious condition, and untreated sleep apnea is linked to cardiovascular disease, stroke, diabetes, and dementia.

You have two options:

  1. Talk to your family doctor — they can refer you for a full in-lab polysomnography sleep study, usually covered by provincial health insurance.
  2. Take a home sleep test — the WatchPAT ONE home sleep test is FDA and Health Canada approved, single-use, and delivered by mail. You wear it for one night, and a sleep physician reviews the results.

CPAP therapy requires a prescription in Canada. Any legitimate retailer will ask for one before shipping a machine.

Frequently Asked Questions

What is the best CPAP mask for beginners?

For most new CPAP users, a nasal mask is the safest starting point. It handles a wide pressure range, doesn't feel as invasive as a full face mask, and works for most sleep positions. The ResMed AirFit N20 is the most-prescribed first mask in Canada. If you know you're a mouth breather, go straight to a full face mask instead.

How much does a CPAP mask cost in Canada?

Most CPAP masks in Canada retail between $100 and $250 CAD, depending on brand and style. Nasal pillow masks are typically the least expensive; full face masks and top-of-head-tubing designs are the most. Replacement cushions cost $25–$60. Public prices are visible at SleepEh.ca, no login required for most masks.

Do I need a prescription to buy a CPAP mask in Canada?

Health Canada regulates CPAP machines as Class II medical devices, which require a prescription. CPAP masks and accessories generally do not require a prescription and can be purchased directly. However, we recommend consulting your sleep clinician for your first mask so it matches your prescribed pressure and breathing pattern.

Can I sleep on my side with a CPAP mask?

Absolutely. Side sleeping is one of the best positions for reducing sleep apnea severity. Choose a mask designed for side sleepers, nasal pillow masks or "top-of-head" tube designs like the DreamWear or AirFit P30i / N30i eliminate hose drag on your pillow.

Why does my CPAP mask leak in the morning but not at night?

You're probably shifting positions overnight, and your mask is slipping. This usually means your headgear needs to be replaced (fabric stretches after 6 months) or the cushion has hardened (silicone hardens after 2–4 weeks). Try a fresh cushion first, it's the cheapest fix and it works about 70% of the time.

How often should I replace my CPAP mask?

Replace the cushion every 2–4 weeks, the headgear every 6 months, and the entire mask system every 3–6 months. Following this schedule keeps your therapy effective and your equipment hygienic. See our CPAP Accessories collection for replacement parts.

What if my mask still doesn't fit after trying everything?

Call us. SleepEh's Canadian sleep specialists are available Monday to Friday, 9 AM to 5 PM EST, at 1-888-998-2538. Sometimes a 10-minute conversation about your face shape, sleep position, and current mask reveals the answer immediately. We'd rather help you find the right mask than sell you the wrong one twice.

The Bottom Line

The right CPAP mask changes everything. It's the difference between dreading bedtime and forgetting your machine is even on. If you take one thing from this guide, let it be this: fit beats brand every time. A perfectly-fitting entry-level mask will treat your sleep apnea better than a poorly-fitting top-of-the-line one.

Start with the mask type that matches how you breathe and sleep. Use manufacturer sizing templates. Replace your cushion on schedule. And when something isn't working, call before you give up, most CPAP therapy failures are mask problems, and most mask problems are solvable.
