Fisher & Paykel Healthcare is the first company to develop an oral mask. The Oracle HC452 delivers air pressure only through a mouthpiece. The mask has been clinically proven to treat OSA and offers a viable alternative to a full face mask, with less structure against the face. This is the second generation of Oracle and builds on the original design.
Here is how it works:
The mouthpiece comes in two sizes and is placed behind the lips and in front of the teeth. An outside flap is then fitted into the mouthpiece and folded over the lips. This combination keeps the device stable in the mouth and has been redesigned without the inner flap of the earlier design, which rested on the tongue.
The features of the Oracle mask include:
Bias Diffuser. The Oracle mask has an exhalation vent design of a series of small holes and uses a filter to help reduce noise. The mask comes with five filters.
Rotating Adjustment Dial. This dial adjusts the space between the SnapFlap Cover and SoftSeal mouthpiece to increase comfort and stability and can be used after the mask has been fitted into the mouth. This is an upgrade to the earlier design of the Oracle.
Single Strap Easy-Release Headgear. One strap around the back of the head keeps the Oracle stable and a swivel in the front of the mask allows free rotation of the CPAP hose. The headgear is adjusted once, then easily removed with just a pull of the Easy-Release cord. No ongoing adjustments are needed. The headgear of the Oracle is latex free, as are all other headgear by Fisher & Paykel.
Tired of adjusting your headgear every time you take your mask off during the night? Quick-Clips allow users to easily remove and replace the mask on your face without re-adjusting the headgear straps.
This describes the type of mask cushion for the mask. These values are either cloth, foam, gel, or silicone. The foam and gel are usually both silicone based materials. The masks that are marked as "silicone" are without gel or foam.
Indicates which masks come packaged with more than one cushion, pillow or prong. Masks can come packaged with ALL Sizes or a combination of sizes as a Fit Pack. This is ideal for users who have not tried the mask before and do not know the right size to select.
This property identifies masks that are ideal for small facial features. Any mask with a size petite or extra small will be marked 'Yes'. Nasal Pillow masks are ideal because they accommodate the size of the 'nare' or nasal openings, not the face.
The value will be marked 'Yes' for CPAP masks with interfaces that are unique to CPAP users with wide facial features. Masks with 'Wide' cushion sizes would fall under this category. Nasal pillow and prong masks are ideal for wide faces because the seal occurs around the nare, not the face.
Do you move around a lot when you sleep? These masks are ideal for users who either sleep on their side or stomach or restless sleepers who toss and turn. There are a few specialized cushions that address this issue as well as most Nasal Pillow and Prong CPAP masks.
These masks are designed to prevent mouth leaks. If you are opening your mouth during the night, airflow escapes and reduces therapy effectiveness. Users who are experiencing a dry mouth, sore throat, or sinus congestion may require a mask that seals around the mouth.
These masks have the least amount of material around the face, fewer headgear points, and offers more freedom when you sleep. Most Nasal Pillow and Nasal Prong masks are ideal for claustrophobic users.
These CPAP masks have interfaces that accommodate a wide variety of facial hair styles. Gel cushions and foam inserts provide support and comfort for users who may need to over-tighten headgear straps to help seal around facial hair. Silicone gel also helps create a fluid seal over the hair.

Heated humidification is required with use of the Oracle 452 Oral Mask due to the CPAP air bypassing the nasal airways which normally moisten the air. With higher CPAP pressures, even a heated humidifier may not provide adequate moisture, especially for patients who also take medications that dry the mouth.
We would first recommend a full face mask due to this humidification issue. Air leaking through the nose can be an issue as well and nasal plugs of various sizes are included with the mask. We have many remarks that the nasal plugs can leak, although this is usually negligible.
If the CPAP pressure is low enough, the Oracle is a good alternative to a full face mask, especially for people with nasal blockage, either from chronic congestion, deviated septum or other type of tissue blockage.
"I am a 90% mouth breather and knew I would need a full face mask for my treatment to be effective. After some time with a full face mask I was so frustrated. Each full face mask I tried always leaked around my nose, and I had to strap them on so tight to prevent leaks that the bridge of my nose became so sore and raw that I couldn't sleep. I finally happened upon this mask and it has made a world of difference!
I have been using the Oracle mask every night for about one month now. This mask does not leak ...period! I keep the strap very loose and don't even need to tighten down the lip adjustment screw... simply amazing! It takes a few nights to get use to having something inside your lips and mouth, but compared to the discomfort of a full face mask, I don't mind at all and I feel so much better in the morning.
A few things I have learned that may help others:
You will probably need some kind of plug to prevent air leaks from your nose. I found the plugs included with the mask uncomfortable and they still leaked for me. I plan to try other solutions (like foam ear plugs), but what will work is taping your nose at night. I use medical fabric tape (available at any pharmacy store) and just run two strips across my nostrils. This works great...until you get a bad nose itch and are forced to either ignore it or remove the tape and scratch. You then need to use fresh tape to keep the seal.
You will drool a bit with the mask in your mouth. I fall asleep pretty quickly, and find it only a nuisance until then...once asleep I am rarely bothered by it. I keep a small hand towel by my pillow to wipe the edges of the mask if it is bothering me.
Others have mentioned that you need humidification. I use a Respironics REMstar M series CPAP with heated humidification. I keep the humidification at 4 and while I sometimes feel a bit dry when I wake up, it hasn't bothered me at all.
If you are a mouth breather and have had similar problems with full face masks, I would certainly give this a try.
I pray that Fisher & Paykel continue production of this mask forever! Also, a thanks to cpap.com for the super service and fast shipment."

HC452 - Great if you can seal your nose
Steven P, ALLEN, TX – January 14, 2010
"I ordered two new masks, this one arrived first. Used this mask/mouth-piece for a week.
The arrangement of air holes and diffuser is effective. It is very quiet, best of 6 masks I've tried.
It is small, no head/pillow orientation limitations.
Because it is held in place by your mouth, the head strap is optional and if used, doesn't need to be tight. No headaches from this one.
What didn't work for me is having to close off the nose to prevent air leaks. Had me waking to a very dry mouth(using a humidifier). I only tried the supplied nose plugs, there may be a better way. As a result, after ~4 hours I would switch back to a Mirage Quattro Full Face. At least until my FitLife Total Face arrived, now it is all I use.
I only gave it one week and I know the instructions for the HC452 say it can take two weeks for it to become more natural. I just didn't have trouble staying asleep with any other mask from my first day using CPAP."
"If you hate the head strap, this is the perfect mask. It takes a bit more cleaning because it goes directly into the mouth, but not having to wear the head strap is well worth it. After a few weeks I didn't even have to wear the neck strap."
Lettye (Loretta) H, TX – February 18, 2014
"I am not as happy with my mask as I had wanted to be. I was really looking forward to being able to use this mask and rest well. That did not happen. The mouthpiece slips and continually wakes me up at night. My throat is so dry in the mornings it hurts. I am going to have to find another option for my mask."
The only mask I can tolerate
Julia H, NC – February 04, 2014
"Being one who can't breathe reliably through her nose due to allergies and a deviated septum, this mask is a God-send. It only took a few times of using it to get the hang of it. Prior to discovering it, I had an assortment of full masks that I NEVER got to work properly for me and I despaired that I would ever be able to have a good night's sleep again. That is, until I discovered this Oracle oral mask. I love it! (Not something I'd ever expect to say about a CPAP mask!). Once you learn how to seal off your nasal passages while you sleep (surprisingly easy!), you don't even need the included nose clip and I've never used the straps--it just stays on all through the night."
An individual who cannot breathe through their nose at all due to a severely deviated septum, nasal congestion or facial injury may find the delivery of the CPAP air stream through only the mouth preferable to a full face mask which delivers air to both the nose and mouth.
Oral masks deliver airflow only to the mouth. The nasal openings or nares are closed with nose plugs. It is highly recommended to use a heated humidifier with an oral mask. Most users find there is a period of adjustment while becoming accustomed to an oral delivery mask.
Do you have a guide to help me choose the right mask?
Yes, we created a Help Me Choose guide to help you select the right mask or machine according to your preferences. The guide asks you a series of questions regarding your preferences and your facial features. Based on your answers we provide you with a comparison chart of the masks that meet your criteria. Get started here:
We work very hard to provide many different ways for our customers to compare products. Here are the machine product guides we have created and maintain:

Masks should be washed daily with warm water using a very gentle soap or baby shampoo, and left to 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.
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.
I breathe through my mouth, what are my options?
People who have a deviated septum or small nostrils, or suffer from season 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 is 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 does not want to or cannot wear a chinstrap, please see our recommended masks for Mouth Breathers.
