    Quick answer

    The **ResMed AirTouch F20** is **not** an under-the-nose mask. It is a **full-face CPAP mask** that seals over the **nose and mouth** with a **memory foam cushion**. In Singapore, it often suits **mouth breathers, people with dry mouth, or users with leak problems on nasal masks**, while **under-the-nose masks** usually suit **nasal breathers who want less facial contact and a more open feel**.

    AirTouch F20 vs Under-the-Nose Masks Singapore

    Key takeaways

    • The AirTouch F20 is not an under-the-nose mask; it is a full-face mask that covers the nose and mouth with a memory foam cushion.

    • Under-the-nose masks come in 3 main styles: nasal cradle, nasal pillows, and hybrid full-face that sits under the nose while still covering the mouth.

    • Sleep apnea severity is commonly described by AHI 5 / 15 / 30 thresholds, but the best mask choice depends more on breathing pattern, leak control, pressure tolerance, sleep position and comfort than AHI alone.

    • In Singapore, climate and bedroom conditions matter. Humidity, air-conditioning, fan use and HDB bedroom temperatures can affect dryness, condensation, skin comfort and mask stability.

    • Comooz, a Singapore CPAP provider (UEN 201808754M), offers a 5-night CPAP trial with deposit + mask cost + $98 return fee; it is not a free trial.

    • Current Comooz machine bundle prices are ResMed AirSense 11 AutoSet Bundle $2,068 nett and ResMed AirSense 10 AutoSet Bundle $1,868 nett, both with built-in humidification and a fitted mask.

    • In Singapore, Comooz can arrange Type 3 home sleep tests on demand and Type 2 home sleep tests manually with a trained specialist, while diagnosis and treatment decisions should be reviewed by a doctor or sleep physician.

    What is the AirTouch F20 and what does “under the nose” mean?

    The AirTouch F20 and under-the-nose masks are different CPAP mask categories. The ResMed AirTouch F20 is a full-face mask, while an under-the-nose mask avoids the nasal bridge and seals either below the nostrils or at the nostril openings.

    The AirTouch F20 covers both the nose and mouth. Its defining feature is a memory foam cushion, which many users choose when they want a softer facial feel than a standard silicone cushion. Because it covers the mouth, it is commonly considered when mouth breathing, jaw drop or dry mouth disrupt therapy.

    “Under the nose” is a shape description, not one single mask type. It usually includes:

    • Nasal cradle masks such as the ResMed AirFit N30 or N30i, which rest under the nostrils
    • Nasal pillows masks such as the ResMed AirFit P10 or P30i, which seal at the nostril openings
    • Hybrid full-face masks such as the ResMed AirFit F30i, which sit under the nose and also cover the mouth

    This distinction matters because seal location affects leak patterns, skin contact, dryness, claustrophobia, side-sleeping behaviour and how stable the mask feels during pressure changes. Comooz, a Singapore CPAP provider (UEN 201808754M), sees this every day during fittings: the “best” mask is usually the one that matches the person’s breathing behaviour, not the one that looks smallest online.

    AirTouch F20 vs under-the-nose masks: key differences at a glance

    The fastest way to compare AirTouch F20 with under the nose masks is to separate nasal-only designs from under-the-nose full-face designs. These are not interchangeable categories.

    Not every under-the-nose mask behaves the same way. A P10 nasal pillows mask and an F30i hybrid full-face mask may both count as “under the nose”, but they solve different problems.

    Singapore comparison: mask choice, trial terms and machine options

    If you are choosing a mask in Singapore, it helps to compare not just shape but also how you can test therapy, what machine support is included and what practical costs apply.

    For many Singapore users, the real question is not “Which mask is best?” but “Which mask lets me actually sleep through the night in my own bedroom conditions?” That includes fan direction, air-con temperature, humidity, sleep position and whether you often wake with a blocked nose.

    How CPAP mask design affects comfort, seal and therapy results

    CPAP mask design directly affects comfort, leak control and whether you can stay on therapy long enough to benefit. Good pressure settings do not help much if the mask keeps leaking or gets removed halfway through the night.

    A full-face mask like the AirTouch F20 creates a larger seal zone across the nose and mouth. This often helps if nasal breathing is unreliable, if the jaw drops during sleep, or if dry mouth on a nasal mask keeps waking you up. The trade-off is more facial coverage and, for some people, more heat or a more enclosed feel.

    How CPAP pressure splints the airway open

    An under-the-nose mask reduces contact on the bridge of the nose. Many users prefer the lighter feel, easier glasses use and less bulky profile. But nasal-only versions depend more on stable nasal breathing. If the mouth opens, therapy air can escape and trigger dryness, noise and less comfortable treatment.

    Mask type also interacts with pressure delivery. An AutoSet machine automatically adjusts pressure within a prescribed range, so some people notice changing pressures through the night. A more stable seal can matter when pressure rises. In a few cases, persistent intolerance leads a clinician to review titration, humidification, pressure range, expiratory comfort, or even whether bilevel therapy with separate inspiratory pressure and EPAP is more appropriate.

    Humidification helps comfort too. Both the ResMed AirSense 11 AutoSet Bundle ($2,068 nett) and ResMed AirSense 10 AutoSet Bundle ($1,868 nett) supplied by Comooz include built-in humidification, tubing, filter, carrying case and a fitted mask. Humidification can reduce dryness, but it does not replace proper mask selection.

    Who may suit the AirTouch F20 better

    The AirTouch F20 usually suits people who need dependable mouth coverage and want a softer-feeling full-face cushion. It is a practical option when the main problem is not “too much mask” but “too much mouth leak”.

    You may prefer the AirTouch F20 if you:

    • Often wake with your mouth open
    • Get persistent dry mouth on nasal-only masks
    • Have inconsistent nasal breathing from congestion
    • Want a memory foam cushion rather than standard silicone
    • Need a full-face option because therapy drops when the jaw relaxes
    • Have repeated leak problems on lighter under-the-nose nasal masks
    • Sleep in strong air-con or directly under a fan and find nasal-only masks too drying
    • Need a mask that continues working even on nights when allergies or a cold make nose breathing worse

    The AirTouch F20 may also be worth discussing if you have tried a nasal cradle or nasal pillows mask and your machine data repeatedly shows leaks despite adjustment. In practice, many “pressure problems” are actually seal problems.

    Who it is not usually for: people who strongly dislike facial coverage, want no nasal bridge contact, mainly breathe comfortably through the nose, or prioritise the most open field of vision.

    Who may prefer an under-the-nose mask

    An under-the-nose mask usually suits users who want less facial contact and can maintain nasal breathing through most of the night. It is often the first shape people ask about when they dislike the idea of a traditional full-face seal.

    You may prefer an under-the-nose design if you:

    • Mainly breathe through your nose during sleep
    • Feel claustrophobic in a traditional full-face mask
    • Want less contact on the nasal bridge
    • Wear glasses or read before bed
    • Sleep on your side and prefer a lighter interface
    • Want a more minimal CPAP feel
    • Get pressure marks on the bridge of the nose
    • Live in Singapore’s humid climate and simply want less face coverage

    For example, some people like the soft simplicity of the ResMed AirFit N30, while others want the top-of-head tube routing of the AirFit N30i or AirFit P30i.

    If you want less bridge contact but still need mouth coverage, an under-the-nose hybrid full-face shape may be the middle ground. That is different from a nasal-only mask and should be compared separately.

    AirTouch F20 vs under-the-nose for common real-life situations

    Choosing between these mask styles becomes easier when you match them to everyday use cases.

    SituationAirTouch F20Under-the-nose nasal maskUnder-the-nose hybrid full-face
    You breathe through your mouthOften a stronger matchUsually less suitableOften suitable
    You have frequent dry mouthOften helpfulOften worsens if mouth opensCan help

    Your nose blocks up some nightsOften more forgivingLess forgivingMore forgiving than nasal-only
    You have claustrophobiaSometimes harderOften easierOften easier than traditional full-face
    You need reliable seal during jaw dropOften strongerOften weakerOften stronger

    This is why many users do not move directly from an AirTouch F20 to a nasal pillows mask, or vice versa, without considering breathing pattern first.

    Common problems: leaks, dry mouth, skin marks, claustrophobia and noise

    Most CPAP mask complaints come from fit, seal geometry and comfort settings rather than brand name alone. A better category match often fixes more than simply tightening straps.

    Leaks

    Leaks happen when the mask shape does not match the face, the size is wrong, the headgear is overtightened, the sleeper changes position a lot, or the cushion is worn. A well-fitted AirTouch F20 can leak less than a badly fitted under-the-nose mask, and the opposite is also true.

    For AirTouch F20 users, leak points may appear at the nose bridge, cheeks or chin area. For under-the-nose masks, leaks often show up as nostril flutter, side leaks or therapy air escaping through the mouth.

    Dry mouth

    Dry mouth strongly suggests mouth opening or mouth leak during therapy. This is the classic reason some users switch from under-the-nose nasal masks to a full-face option like the AirTouch F20.

    In Singapore, dry mouth can still happen even with humidification if the bedroom air-con is very cold, the fan is blowing directly at the face, or the mouth opens repeatedly overnight.

    Skin marks and irritation

    The AirTouch F20 memory foam cushion can feel gentler for some users who struggle with silicone. But comfort is individual. Skin oils, replacement timing, headgear tension, skincare products and cleaning routine all affect long-term results.

    Under-the-nose masks reduce bridge contact, but they can still irritate the base of the nostrils if the size or angle is wrong.

    Claustrophobia

    Under-the-nose designs often feel less enclosing because they reduce facial coverage and leave the bridge area open. If you keep removing a full-face mask early in the night, this can matter more than theoretical leak advantages.

    Noise

    Noise usually comes from escaping air, vent flow or cushion flutter. A noisy mask does not automatically mean the mask is wrong; it may need a different size, angle or category.

    Blocked nose

    If your nose is regularly blocked from allergy, sinus issues or a cold, a nasal-only under-the-nose mask may become difficult to tolerate. In that situation, a full-face option such as the AirTouch F20 is often more practical to discuss with a provider.

    Rainout or condensation

    In air-conditioned Singapore bedrooms, some users notice water droplets in the tubing or mask, especially when humidification is set high and room temperature is low. This is a comfort-setting issue rather than a reason by itself to abandon a mask category. A provider can review humidification, tubing setup and room conditions.

    Side sleeping, facial hair, glasses and Singapore bedroom conditions

    These practical issues often matter as much as the mask category itself.

    Side sleeping

    Many side sleepers prefer under-the-nose masks because they are lighter and put less material between the face and pillow. That said, some side sleepers do very well with the AirTouch F20 once the cushion size and strap tension are correct. A CPAP pillow or careful pillow edge positioning may also help.

    Facial hair

    Beards and stubble can affect any mask seal. In general, a larger full-face seal area can be more sensitive to facial hair, but this varies by beard density, trimming and face shape. Some users with facial hair still do well on the AirTouch F20, while others seal better with a smaller under-the-nose interface.

    Glasses and reading in bed

    Under-the-nose masks are usually easier if you wear spectacles, use your phone or read before sleeping because they leave more of the face open. The AirTouch F20 is bulkier in front of the nose bridge and may feel less convenient for this routine.

    Singapore humidity and air-conditioning

    Singapore’s climate creates a mixed picture. Natural humidity can help some users feel less dry, but cold air-con and direct fan airflow can still increase dryness, condensation and discomfort. If you sleep in an HDB or condo bedroom with strong overnight cooling, mask comfort may depend on both humidification settings and where the airflow hits your face.

    How to choose the right mask in Singapore without guessing

    The best way to choose between AirTouch F20 and under the nose masks is to match the mask to the problem you are trying to solve. Do not choose only by appearance.

    Start with diagnosis. Obstructive sleep apnea is usually assessed using sleep testing and event frequency. The common AHI thresholds are:

    AHI rangeUsual category
    5 to 14Mild
    15 to 29Moderate
    30 and aboveSevere

    Apnea-hypopnea index severity scale

    A home sleep test is a simplified sleep study done outside a lab. In Singapore, Comooz can arrange Type 3 home sleep tests on demand, while Type 2 home sleep tests are arranged manually with a trained specialist. A polysomnography study or review by a sleep physician may still be needed for more complex cases, unusual symptoms or unclear results.

    Then ask these practical questions:

    • Am I a mouth breather, nasal breather or mixed breather?
    • Is my real problem dryness, bridge pressure, claustrophobia or leak?
    • Do I need a full-face seal or just less bulk?
    • Is nasal blockage making a nasal-only mask unrealistic?
    • Did my issues start after a pressure change or poor titration?
    • Would humidification adjustment help before changing mask style?
    • Do I sleep mostly on my side or back?
    • Do I have facial hair that changes the seal?
    • Does my bedroom air-con or fan make me drier or noisier on one type of mask?

    If you are still at the diagnostic stage, Comooz explains the process in its home sleep test guide. For broader CPAP education, see the sleep apnea learning centre.

    What to ask a CPAP provider or sleep doctor before switching masks

    Before switching masks, ask questions that identify the root cause. The goal is not just a new mask; the goal is effective, tolerable therapy.

    Ask:

    • Is this a mask-fit problem or a treatment-setting problem?
    • Does my leak data suggest mouth leak, cushion leak or pressure intolerance?
    • Would a full-face mask better suit my breathing pattern?
    • If I want an under-the-nose option, should it be nasal-only or hybrid full-face?
    • Do I need humidification changes?
    • Has my titration been reviewed if symptoms persist?
    • Should a sleep physician review my case if I still feel sleepy?
    • Is my current cushion size correct for my face?
    • Are skin products, beard growth or strap wear affecting the seal?

    This matters because ongoing symptoms can reflect untreated or undertreated sleep apnea, central events, or settings that need adjustment. Mask swaps help many people, but they do not replace medical review.

    Frequently asked questions

    Is the AirTouch F20 an under-the-nose mask?

    No. The AirTouch F20 is a full-face CPAP mask that seals over the nose and mouth. An under-the-nose mask sits below the nostrils instead of covering the bridge of the nose, and it may be either nasal-only or hybrid full-face depending on the model.

    Does the AirTouch F20 go over the nose bridge?

    Yes. The AirTouch F20 seals around the nose and over the mouth, so it includes contact around the nose bridge area. If you specifically want to avoid nose bridge contact, an under-the-nose mask is usually the category to ask about.

    Which is better for mouth breathers: AirTouch F20 or under-the-nose masks?

    Many mouth breathers do better with the AirTouch F20 because it continues delivering therapy even if the mouth opens during sleep. Some under-the-nose masks can also work, especially hybrid full-face designs, but nasal-only under-the-nose masks are more likely to cause dry mouth or therapy air escape.

    Do under-the-nose masks leak less than the AirTouch F20?

    Not always. Leak performance depends on fit, sizing, facial structure, sleep position, pressure range and breathing pattern. A properly fitted AirTouch F20 may leak less than a poorly matched under-the-nose mask, while a stable nasal breather may do very well on a minimal under-the-nose option.

    Is memory foam on the AirTouch F20 more comfortable than silicone?

    Some users find the AirTouch F20 memory foam cushion softer and gentler on the skin than silicone, especially if they dislike bridge pressure. Others prefer silicone for feel or routine care. Comfort is individual, so the right answer depends on fit, skin response and how the mask behaves during real sleep.

    Can I use an under-the-nose mask if I have high CPAP pressure?

    Possibly. Some users do well on under-the-nose masks even at higher pressures, but leak control becomes more important as pressure rises or varies during AutoSet therapy. If you struggle, a provider should review sizing, humidification, leak data and whether a different mask category is more suitable.

    Is the AirTouch F20 good for side sleepers?

    It can be. Some side sleepers use the AirTouch F20 successfully, especially when the cushion size is correct and the pillow is not pushing the mask out of position. However, many side sleepers prefer under-the-nose masks because they usually feel lighter and have less bulk at the front of the face.

    Is an under-the-nose mask better if I feel claustrophobic?

    Often yes. Under-the-nose masks usually feel more open because they leave the nose bridge and more of the face unobstructed. If claustrophobia is your main problem, this category is often worth discussing first, provided your breathing pattern still suits it.

    Can I use the AirTouch F20 if I have a beard?

    Possibly. Facial hair can affect any CPAP mask seal, including full-face and under-the-nose designs. The best option depends on beard density, trimming, face shape and leak pattern. A fitting session is often the fastest way to tell whether the AirTouch F20 or a smaller-contact mask seals better for you.

    Is an under-the-nose mask better for blocked nose or sinus issues?

    Not usually if your nose is significantly blocked. Nasal-only under-the-nose masks rely on nasal breathing, so they can become difficult on nights when congestion is worse. If nose blockage is frequent, a full-face option such as the AirTouch F20 may be more practical to discuss with a provider.

    How do I clean an AirTouch F20 versus an under-the-nose mask?

    Cleaning routine depends on the cushion material. In general, CPAP masks need regular cleaning according to the manufacturer’s instructions, and memory foam cushions should not simply be treated the same way as standard silicone. If you are comparing masks, ask the provider to show you the care routine, replacement schedule and what products to avoid.

    How do I know whether my mask problems are from the mask or untreated sleep apnea?

    Mask leaks, dry mouth, discomfort and noise can all reduce effective CPAP use, but persistent sleepiness or snoring can also mean therapy settings or diagnosis need review. Do not self-diagnose. A provider or sleep doctor may suggest data review, titration follow-up, or sleep testing such as a home sleep test or polysomnography.

    Frequently asked questions

    Is the AirTouch F20 an under-the-nose mask?
    No. The AirTouch F20 is a full-face CPAP mask that covers both the nose and mouth. Under-the-nose masks rest beneath the nostrils instead of covering the bridge of the nose, and some designs also cover the mouth while others are nasal-only.
    Which is better for mouth breathers: AirTouch F20 or under-the-nose masks?
    Many mouth breathers do better with a full-face mask like the AirTouch F20 because therapy can continue even if the mouth opens during sleep. Some under-the-nose options can also work, especially hybrid full-face designs, but fit and leak control should be checked carefully.
    Do under-the-nose masks leak less than the AirTouch F20?
    Not always. Under-the-nose masks may feel lighter and can reduce pressure on the nasal bridge, but leaks depend on facial structure, sleep position, pressure settings and sizing. A well-fitted AirTouch F20 may leak less than a poorly fitted under-the-nose mask.
    Is memory foam on the AirTouch F20 more comfortable than silicone?
    Some users find the AirTouch F20 memory foam cushion softer and gentler on the skin than silicone. However, comfort is individual, and foam may not suit everyone. Skin sensitivity, humidity, cleaning routine and replacement schedule all affect long-term comfort and performance.
    Can I use an under-the-nose mask if I have high CPAP pressure?
    Possibly, but higher pressures can make some lighter masks more prone to leaks or discomfort if the fit is not right. Some users still do well with under-the-nose designs at higher pressures. A clinician or experienced CPAP provider should review fit, leak data and comfort.
    How do I know whether my mask problems are from the mask or untreated sleep apnea?
    Mask discomfort, dry mouth or leaks can reduce CPAP use, but persistent sleepiness, snoring or awakenings may also mean your therapy settings or diagnosis need review. Do not self-diagnose. If symptoms continue, speak to a sleep doctor and consider formal testing or therapy follow-up.
