Nasal FAQs

 Why might I prefer a nasal mask?

The ideal CPAP mask is not noticeable to the user during CPAP therapy. If you breathe through your nose only, the nasal mask may offer the best therapy. Nasal cushions create a very good seal around your nose, while keeping a small profile. Also, nasal masks can be found in silicone, gel, foam, or cloth material. The SleepWeaver masks are the only cloth masks on the market, and are a very popular choice among nasal mask users. Lastly, most nasal masks have a forehead support which offers stability and support for the mask.

 How do I care for my mask?

Masks should be washed daily with warm water and gentle soap or baby shampoo. Let the mask air dry. Never use antibacterial soap as it will break down the silicone of the mask cushion. Avoid soaps that include lotion which can coat the mask and cause it to lose its seal. A safe cleaner is the Control III Disinfectant CPAP Cleaning Solution. Remember, going to bed with a clean face will improve your seal and protect the lifespan of your mask.

The best time to clean your mask is in the morning after use. This removes the oils left behind from your skin which can reduce the lifespan of your mask. We recommend using Mask Wipes to make daily morning cleaning easy. The mask wipes are made from materials that will not break down your mask.

For customers who want to completely disinfect their mask and accessories, there's an even better option than wipes. The Lumin Mask and Accessories Cleaner uses powerful UV light to disinfect, killing almost all bacteria almost instantly. It's not a cleaner and doesn't scrub or wash anything, but for simple disinfecting the Lumin works great!

 How often should I replace my mask?

Medicare allows for mask cushion replacement every three (3) months, and a complete mask system replacement every six (6) months. CPAP manufacturers and vendors suggest these replacement schedules as well.

In our experience, most mask cushions begin to deteriorate after about six months of use. The cushion eventually becomes too soft to hold a seal. The headgear straps lose elasticity and must be tightened more and more to get the same quality seal.

We strongly suggest replacing cushions and pillows as soon as they start to soften. Air leaks may reduce the effectiveness of CPAP therapy and headgear that is too tight may cause facial sores at pressure points. In most cases, replacement headgear is available if it is stretched out or the Velcro worn out.

To see what parts of your mask are replaceable refer to our Replacement Part Finder. Just search for your mask to see all of the replaceable parts.

 How can I find replacement parts for my CPAP mask?

Replacement parts such as: mask cushions, headgear, headgear clips, and others are available for many masks.

To find parts which are compatible with your mask, or to find which parts of your mask are replaceable, do the following:

• Use our Replace Part Wizard to identify your mask and see all the related parts.
• Browse for your mask and then click the "Replacement Parts" button on your mask's product page.

 Are mask cushions interchangeable with other mask frames or can I use a different size cushion on the same frame?

The answer to this question depends on the mask. In most cases, the mask frame will only accept cushions or pillows made for that specific mask. However, there are a few variations to this rule: ResMed's Mirage SoftGel Nasal CPAP Mask and Mirage Activa LT Nasal CPAP Mask are examples of the exception. In this case, both masks use the same mask frame; therefore, the cushions for the two masks are interchangeable. The EasyFit Masks by DeVilbiss offer different cushion types such as gel or silicone, which are interchangeable between the mask frames.

As to whether or not you can use different size cushions for a specific mask on the same mask frame, this also depends on the mask. Some mask frames are compatible with multiple cushion or pillow sizes, while other mask frames only fit cushions of the same size. This information is provided on the product pages. Please review the page of the specific product you are interested in to learn if you will need a different size mask frame for each size of cushion or pillow. For assistance, contact us at 800.356.5221.

 I breathe through my mouth, what are my options?

People who have a deviated septum, small nostrils, or who suffer from seasonal allergies or chronic sinus issues, may breathe through the mouth rather than the nose. If you are a person who breathes through your mouth you may be able to wear most masks with a few adaptations. Add a Chinstrap if using nasal pillows, nasal prongs or a nasal mask.


A full face mask or hybrid mask can be used without a chinstrap because the seal covers both the nose and mouth. A full face mask will allow you to breathe through your mouth or through your nose.

If you suffer from chronic sinus issues, a full face mask or an oral face mask are good options. Oral masks work best for mouth breathers with blocked nasal passages. You must use a heated humidifier with the oral mask. CPAP.com sells the Oracle HC452 Oral CPAP mask.

If you are a mouth breather who cannot or who does not want to wear a chinstrap, please see our recommended masks for Mouth Breathers.

Here are some suggested items that may help with mouth breathing:

Hybrid Masks
Oral Masks
Full Face Masks
Chinstraps

 What masks are recommended for people with small faces?

Nasal pillow and nasal prong masks seal only at the nostrils or nares. Therefore, only the size of the nostrils has to be considered when selecting a delivery system. Also, most nasal pillow masks include small, medium, and large nasal pillow cushions to offer the user multiple options. Some nasal and full face masks are offered in smaller sizes.

We have created a selection filter so you can easily see the masks that we would recommend for people with small faces. View Masks for Small Faces.

 I sleep on my side or stomach, what are my options?

Sleeping on your side or stomach is preferable to sleeping on your back because sleeping on your back worsens all forms of sleep-disordered breathing. However, sleeping on your side or stomach can present problems with CPAP therapy. Both positions can put pressure on one side of your mask increasing your leak rate. Your options are to (1) try a mask that other side sleepers like (2) try bed pillows made for CPAP users.

• Masks: In our experience, some masks allow for movement in different sleeping positions better than others. See our recommended masks for Active or Side/Stomach Sleepers.
  
  
• Special CPAP Pillows: Regular bed pillows can put pressure against the mask and cause leaks. CPAP pillows are made with CPAP users in mind. These special pillows are designed to minimize the contact of the CPAP mask with the pillow, even when you are sleeping on your side.
  

 What type of mask works for people with full beards?

Full face masks work well for CPAP users with full beards. One tip is to smooth the beard with lanolin to soften the beard where the seal makes contact.

Nasal pillow masks are also liked by full bearded CPAP users. If you are a person who breathes through your mouth remember to use a chinstrap.

Total face masks encompass the entire face and can be an option for people with facial hair.

Masks with a gel or foam cushion can also be better with facial hair as they are able to mold better to the face to create a seal.

See our recommended masks for people with Facial Hair.

 Which CPAP masks work on which machines?

Any mask will work with any machine, with one important exception. The ResMed AirMini is only compatible with certain ResMed CPAP masks. Compatible masks for the AirMini are as follows:

• ResMed AirFit™ N20 Nasal Mask
• ResMed AirFit™ F20 Full Face
• ResMed AirTouch™ F20 Full Face
• ResMed AirFit™ P10 Nasal Pillow

When considering another CPAP, APAP or BiPAP machine from ResMed or any other manufacturer, mask compatibility extends to all brands. The AirMini uses non-standard tubing to connect the machine to the mask, and is the primary reason why other masks won't work with the AirMini. Despite this issue, many of our customers consider the AirMini to be an excellent machine.

 How do I avoid red marks?

Most red marks on the face are caused by over tightening the CPAP mask. CPAP masks should only be tightened down enough to create a seal. To avoid over tightening your mask, you should work clockwise around the mask, making small adjustments to the headgear, until the mask is securely in place but not overly tight. You should avoid pulling too much on one side of the mask than on the other.

By cleaning your mask cushion, nasal pillows, and nasal prongs on a daily basis, you ensure a better seal each time you put on your mask. If you know you have a mask that fits, and are cleaning it daily, and still have red marks, consider using Mask Straps Pads which are soft covering for the headgear straps.

 Why is my face breaking out around my nose?

Sores, redness and bumps around your nose can be caused by one of three main reasons: facial oils are building up under the mask material; the mask is overly tight; or the mask material is causing an allergic reaction.

A breakout can occur from the facial oils building up under the mask at night. You can help minimize this by washing your face before putting on the mask at night and by cleaning the facial oils off the mask every morning. If you are still experiencing a breakout, you might consider Nasal Pillow Masks. The nasal pillow design has less material in direct contact with the skin.

Sores at the bridge of the nose or below the nose are usually due to tightening the headgear straps too much. The pressure will create soreness, then a bruise, and may eventually create an open sore if left untreated. Your mask should seal when worn comfortably. If you have to over tighten your mask to get a good seal, consider switching to another mask type. To avoid over tightening your mask, you should work clockwise around the mask, making small adjustments to the headgear, until the headgear is securely in place but not overly tight. You should avoid pulling too much on one side of the mask than on the other.

Most masks are made of silicone, which is an inert substance. But silicone is manufactured in chemicals to which some people are allergic. The chemicals normally degrade and disperse over time, but may cause a reaction when first used. The solution is to remove surface chemicals before using the mask. Washing the mask will reduce or eliminate the problem. This process can be accelerated by long soaks in warm soapy water. This method can be used with all types of masks, and should also be applied to mask replacement parts. While soaking the mask will help remove the surface chemicals, it my reduce the life of the silicone.

 Why do I wake up to find my mask is off?

People tend to remove their masks during sleep because they are not getting enough air.

The CPAP pressure may be reduced if your mask is leaking. Your mask may be too big or too old. We would suggest you resize your mask to be sure you have the best fit. If your mask fits, but it is six to nine months old, it should be replaced. As the silicone in the mask cushion ages, it deteriorates and becomes too soft to hold a seal. For many masks, you can get a replacement cushion. See our Replacement Part Finder to see if your mask has a replaceable cushion.

If the CPAP air is being delivered effectively and without leaks, it may be that the pressure is set too low. Pressure settings may require change due to weight gain or loss and aging. You should speak to your doctor if you think your pressure may need to be adjusted.

An auto-adjusting CPAP machine (APAP) may be another solution. An APAP machine will provide the minimum amount of pressure required to keep your airway open on a breath-by-breath basis. With an APAP you can be sure your machine is always providing the correct amount of pressure needed.

 Why is air leaking from my mouth?

It is common for air to leak from the user's open mouth during CPAP therapy. Many factors can cause the user's mouth to fall open. For example, a common catalyst for mouth breathers' is nasal irritation from CPAP therapy.

The correlation between a lack of humidification and mouth leaks is a topic that has been heavily researched. The hypothesis is that a significant amount of mouth leakage is caused by the following cycle:

• CPAP therapy is used with ineffective or no humidification,
• The nasal membranes are unable to adequately condition the increased airflow and after a few minutes the airway and nasal passages become dry.
• To remedy the dryness and obtain moisture, the body uses the mouth to breathe.
• CPAP air follows the path of least resistance and leaks out of the open mouth.
• The air leaking through the mouth causes more dryness.
• Patient wakes up feeling tired with significant dryness in mouth and dry, swollen nasal passages.

The answer to this cycle is humidification. If the mouth continues to open during sleep, a Chinstrap may be needed to hold the jaw up so that the mouth can close. If mouth breathing continues, a full face mask, hybrid mask, or oral mask is suggested. See our recommended masks for Mouth Breathers.

 How do I stop mask leaks?

Air leaks can be caused by masks that are too big, too old, or simply the wrong style.

Air leaking into the eyes is usually an indication that the mask is too big (long or wide) as are leaks at the base of the nose. Leaks may also occur under the nose due to facial hair.

As the silicone in the mask cushion ages, it deteriorates and becomes too soft to hold a seal. For many masks, the cushion may be removed and replaced to extend the life of the mask. View our Replacement Part Finder to see if a replacement cushion is available for your mask.

When a cushion has softened to the point where it will no longer hold a seal, you may be able to tighten it enough to stop the leaking when you go to sleep, but during the night the seal will loosen and leak.

Mask leaks may also be caused by the pillow pushing against the mask and changing the position and seal of the mask. There are special CPAP Pillows which are are designed to minimize the contact of the CPAP mask with the pillow, even when you are sleeping on your side.

Here are some suggested items that may help reduce mask leaks:

Silent Night Full Face Mask Liners
LiquiCell Nasal CPAP Cushions
RemZzzs Nasal CPAP Mask Liners

 Why is the bridge of my nose sore?

Sores at the bridge of the nose or below the nose are usually due to tightening the headgear straps too much. The pressure will create soreness, then a bruise, and may eventually create an open sore if left untreated.

Headgear is usually tightened too much to reduce or eliminate air leaks. A small degree of this may be necessary, but too much is an indication that the mask is too large, too old, or the wrong style.

If your mask is six to nine months old and the silicone is becoming too soft to hold a seal, try replacing it. Find the right replacement cushion for your mask using our Replacement Part Finder.

It is usually necessary to stop wearing a mask to allow these sores to heal. Nasal Pillows are an option in the meantime.

Here are some suggested items that may help with sore nasal bridges:

Nasal Pillow Masks
Boomerang Gel Pad
Hybrid Masks
LiquiCell Nasal CPAP Cushions

 Why do I wake up feeling bloated with air in my stomach and intestines?

Bloating is a sign you are swallowing the CPAP air. There is no real medical solution, but we have found that your sleeping position may be a factor. First, try sleeping as flat as possible, even without a pillow. If the bloating persists, try sleeping on your side or elevated. The position must be different from your current posture.

If changing your position doesn't resolve the problem, talk to your doctor about the possibility of lowering your pressure a bit. It may let a few apneas through, but the trade-off might be worth it.

 Why do I wake up with dry eyes?

Air leaking from the mask at the bridge of the nose and over the eyes during sleep will cause the eyes to dry out. The most common reason for air leaking at the nose bridge is that the mask is too big or too long for the nose.

We would suggest you resize your mask to be sure you have the best fit. A mask that has an adjustment at the bridge may also be helpful in getting a good fit. Nasal pillow or nose cushion devices which do not rest on the nose are also an option.

It is not advisable to tighten the headgear to eliminate the air leak. Pressure from a mask that is too tight will cause bruises and even open sores if applied long enough.

Here are some suggested items that may help reduce mask leaks:

Silent Night Full Face Mask Liners
LiquiCell Nasal CPAP Cushions
RemZzzs Padded Full Face CPAP Mask Liners

 Why is my mouth dry in the morning?

Dry mouth is a sign that you are opening your mouth while you sleep. If you use a nasal mask, breathing through your mouth bypasses any humidification you may be using so increasing the heat will not be effective. Breathing through your mouth while using a nasal mask reduces the benefit of CPAP therapy.

First, be sure the mask is not leaking. If the mask is six to nine months old and leaking, try replacing it. If it is new and leaking, the fit could be incorrect. We can help you find a mask with a great fit.

If your mask is new and NOT leaking, try a Chinstrap to keep your jaw up and mouth from dropping open during sleep. If a chinstrap doesn't solve the problem, try masks recommended for Mouth Breathers.

If you use a full face mask and have a dry mouth, try adding a Heated Humidifier to add moisture.

Here are some items we recommend that may help with dry mouth:

Heated Humidifiers
Full Face Masks
Chinstraps
Heated Tubing

 Why is my nose so dried out?

The primary reason nasal passages can become dry from CPAP use is lack of adequate humidification.

CPAP air is an irritant - to one degree or another - to everyone. The irritation may cause the nasal passages to dry out and bleed, or the mucous membranes may try to protect the nasal passages by producing excess mucous, resulting in congestion. The irritation can be cumulative, developing over time. Furthermore, dry, cracked or bleeding nasal passages are a breeding ground for infection.

Using a Heated Humidifier to add moisture to the CPAP air may reduce or eliminate the irritation. An unheated, Passover Humidifier may not offer enough additional moisture. If you are already using a heated humidifier, try turning it up to a higher setting. If that produces condensation in the six foot hose, you should try an Insulating Cover for the hose. You can also try using a Nose Lubricant to reduce the dryness.

Here are some items we recommend that may help dry nasal passages:

Moisture Therapy Cream
NasoGEL

 Why am I congested from CPAP use?

The primary reason nasal passages can dry out from CPAP use is lack of adequate humidification.

CPAP air is an irritant - to one degree or another - to everyone. The irritation may cause the nasal passages to dry out and bleed, or the mucous membranes may try to protect the nasal passages by producing excess mucous, resulting in congestion. The irritation can be cumulative, developing over time. Furthermore, dry, cracked or bleeding nasal passages are a breeding ground for infection.

Add a Heated Humidifier to add moisture to the CPAP air and reduce or eliminate the irritation. A passover humidifier may not offer enough moisture. If you are already using a heated humidifier, try turning it up to a higher setting. If that produces condensation in the six foot hose, you should try an Insulating Cover for the hose. You can also try using a Nose Lubricant to reduce the dryness.

You can also try using a Sinus Rinse before going to bed and again once you wake in the morning to help clear your sinuses.

 What can I do for sinus and congestion relief?

A lot of new CPAP users report having an increase in sinus congestion after starting CPAP therapy. When treating your obstructive sleep apnea, sinus congestion presents a roadblock to healthy breathing. CPAP air is an irritant - to one degree or another - to everyone. The irritation may cause the nasal passages to dry out and bleed, or the mucous membranes may try to protect the nasal passages by producing excess mucous and so congestion results.

The best option is to add a Heated Humidifier to add moisture to the CPAP air and reduce or eliminate the irritation. If you are already using a heated humidifier, try turning it up to a higher setting. If that produces condensation in the six foot hose, you should try an Insulating Cover for the hose. Other options are to:

• Wait and see if humidification adjustments help decrease the congestion.
• Visit your the ENT (ear nose and throat) doctor, and let them know you are on CPAP therapy.
• Try using a Sinus Rinse before going to bed and again once you wake in the morning to help clear your sinuses.

As a general rule, those with obstructive sleep apnea should avoid using sedating medicines. Sedatives relax the muscles of the air passage even more and can effect your apneas. You should consult your doctor before using these types of medicines.

Here are some items we recommend that may help with sinus relief:

Heated Humidifiers
Bacteria Filters (5-Pack)

 Does this product contain BPA?

Yes, all CPAP masks and CPAP humidifier chambers either contain BPA or their manufacturer has not released a statement calling their products BPA free. Here is a statement released by Respironics:

Government of Canada Takes Action on Another Chemical of Concern: Bisphenol A

April 25th 2008

To Whom It May Concern

This document represents Respironics' position regarding the use of Bisphenol A in Respironics Sleep and Home Respiratory Devices. On April 18, 2008, the Government of Canada, banned the use of Bisphenol A (BPA) in polycarbonate baby bottles, claiming that the exposure to BPA on newborns and infants up to 18 months of age, could potentially present a health risk to this patient group when the polycarbonate baby bottles are exposed to high temperatures.

At this time, we are able to provide the following information to our customer: NONE of our Sleep and Home Respiratory products which are either breathable or skin contacting are intended for use with newborns or infants under 18 months of age. Therefore, Respironics is in compliance with Health Canada's position for exposure for the identified at risk patient population.

Although Health Canada's restriction for BPA does not include products used for ages above 18 months at this time, Respironics is evaluating its product portfolio and will take the appropriate actions to determine and mitigate any potential risk from use of its products or potential exposure to BPA. It should be noted that NOT all polycarbonate resins contain BPA. In response to the direction provided by Health Canada's device licensing division, Respironics will be evaluating all of our Class II and III medical devices to determine if the resins used in the manufacturer of its products contain BPA.
