Oracle 452 Oral CPAP/BiPAP Mask FitPack with Headgear

The mouthpiece's new Rotating Adjustment Dial is infinitely adjustable to create a perfect fit in the mouth and it's easily adjustable even when the mask is on. As with the original Oracle Oral Mask the 452 is an ideal solution for people who can't tolerate a nasal interface. It's also great for habitual mouth breathers or those with severe nasal problems.

The Oracle 452 is an oral mask - NOT an oral appliance. It is designed to float in the mouth and is retained in position by two silicone components that form a pressure seal against the inner and outer cheek. No dental fitting is required. The Oracle should only be used with Heated Humidification.

Unlike many facial masks, the Oracle can be worn with dentures and glasses, causes fewer skin abrasions and creates less leakage.

The second generation Oracle Oral mask from Fisher & Paykel builds on the original breakthrough design and adds some great new comfort refinements.


  • Floats comfortably in the mouth
  • No headgear needed, providing a simple fit and more freedom to move. Headgear (for optional use) is included with each mask pack.-
  • Easy fit of the mouthpiece prevents skin abrasions from pressure points
  • Rotating Adjustment Dial - Infinitely adjustable to provide greater comfort and simple personalized fitting
  • SoftSeal Mouthpiece and SnapFlap Cover - Work together making it easy to use and easy to seal
  • Comes with 2 sizes of SoftSeals (Small and Large) for a better fit
  • Flexitube tubing position can be rotated 360º for perfect positioning
  • Chin straps are eliminated resulting in a less cumbersome setup. Also, the concern of mouth leak is eliminated
  • Three sizes of nasal plugs (for optional use) included in each mask pack. Nasal plugs can be used to help reduce nasal breathing and dryness when using the Oracle mask.
  • Less intrusive as you can still wear your glasses
  • Able to be used with dentures
  • Improved patient comfort increases patient compliance

Best mask for a
4 out of 54 out of 54 out of 54 out of 54 out of 5
Even on a good day, I cannot breath through my nose comfortably. My sinuses are just too restricted. I was about ready to give up on CPAP/BiPAP because the nasal or nasal + oral masks (with a mandatory chin strap to keep my mouth closed) were a nightmare. Nothing fit well enough for me to sleep more than 4 hours. I would wake up in severe pain after that, and it would take at least an hour for the red marks on my face to fade. My machine is set at 15 PSI, and I really had to tighten the masks down to get a decent (not even good) seal. I have been using this mask for about a year now, and it is more comfortable and effective than any other I have tried. Even though I have a mustache, it seals well (probably because the seal is inside my mouth). I don't get red marks on my face, or air leakage through my nose. I consistently get 6+ hours of sleep before waking, and that was what I used to get before the sleep apnea. It should be cleaned properly daily, which takes about 2 minutes, and works well for me.

Review of Oracle 425 Oral cpap mask
2 out of 52 out of 52 out of 52 out of 52 out of 5
The product itself seems to be of good quality, but I don't think that it is going to work for me. It just feels very uncomfortable to me. Honestly, I haven't worn it at night yet because it was so uncomfortable even when I just tried it on. I will probably have to try something else or go back to what I have been using. Either way I will continue to use cpapXchange because I have had great service. I will be looking in to it more before I know for sure. Thankfully I did purchase the insurance so that I can exchange.

Hate it. Sore throat and ansal passages even with the humidity chamber warmed up to peak setting, distilled H2O at fill point, it still iritates mouth-throat-nose and ears. I'm going to trash it.

Better than anything I have tried so far.

This one just might work you can hardly tell you have it on and it is very quite. All the others are so heavey and bugs me all night. This one is not as heavey and I can not even tell it is on my face. Thank you for making a mouth one. I have been able to last 4 hours on this one where the others were about 30 min.

I am sleeping better at night. I am becoming adjusted to the dryness in my mouth caused by the product, even while I'm using warmed water in the CPAP machine. I would recommend this product to those who breath through their mouth in their sleep, or have obstructed nasal breathing.

Excellent product w/minor design flaw
4 out of 54 out of 54 out of 54 out of 54 out of 5
I have used the Oracle 452 Oral CPAP/BiPAP Mask for about 5 years now. I love the product & it is the only mask I will use because I am a mouth breather who has constant sinus trouble even after 2 sinus surgeries. I prefer to use the head strap with the mask in order to prevent the mask from coming out of my mouth when my jaw goes slack. Now for the design flaw... When using the head strap, the holes it attaches to on the mask are located too close to the edge of the unit. By being located where they are, there is not enough material on the edge of the holes & I inevitably pull the strap hooks through the silicone like material. I typically can get one of these masks to last 6-8 months, & my insurance will replace them every 6 months, but I have had them fail in as short as 3-4 months of use. This design flaw could easily be fixed by moving the holes another 1/8" to 3/16" in from the edge, leaving more material for the head strap hooks to hold on to.

Hi, The mouth mask is great, I need a little more adjustment time but the idea for mouth breathers is good. I am sleeping better and the dry mouth is not to bad. Everyone should use the nose plugs, they feel a little funny at first but are a big help, when using a mouth mask.

A mouth breather's best mask
5 out of 55 out of 55 out of 55 out of 55 out of 5
I am a mouth breather mostly because I have a large overbite and I can't really close my mouth tight, the teeth just don't match up. Anyway, I've tried all the other masks and there are very few for mouth breathers- the Hans Rudolph and the Fisher & Paykel 432 and Forma and that is about it... I couldn't use a chin strap because it made my TMJ hurt. So I've tried this "Oral" mask on a whim and IT'S FANTASTIC! There is no leaking. The only problem is the nose plugs that come with the deal. I've had to use swimmer's nose clips instead. But it works and works well. I've found a great nose clip from Harvard Apparatus (599673 Reusable Nose Clip) and I'm going to order one soon. I don't like putting anything into my nose and it gets me claustrophobic to wear the ones that come with the mask. Even with my overbite the mouthpiece stays in my mouth. I also talk in my sleep and it stays in for that too. And, the amazing thing is that this particular mask is CHEAP compared to other masks made for mouth breathers! It is so easy to wear I forgot to snap in the headgear and the mouthpiece stayed in my mouth all night long anyway! I did accidentally ruin the filter in the top of the hose the first time I washed it though... don't forget there is a small filter there!!! But they include 5 extra filters in the box just for that reason! I'll probably have to keep extras on hand just in case! This mask is easy to clean and wear. If you are a mouth breather it is worth a try and it would be great to have on hand if you are prone to head colds or allergies that block your sinuses. I'm going to try to order another one to have on hand in case they discontinue this mask. Everyone always discontinues the things I like... from make-up to food so I'm going to try to stock up on this mask!

This mask is wonderful! As a former snorkeler, I find this just as comfortable. No more masks for me. They always leaked around the edges because of my beard. This is the appliance for me. I highly recommend it for others.

Not a fan of the Oracle 452 Mask

Leaks, mouth piece is very large and the strap was also made for a very large head/neck. I would not recommend this product.

Delivered early and 100% complete
5 out of 55 out of 55 out of 55 out of 55 out of 5
I've been using this mask for about 5 years now, and it is the only mask that works for me. I have a mustache, and this mask doesn't leak. Once adjusted correctly (a 3-minute process), it works well. My mouth is dry when I wake up, but that's not a big thing, especially since I can actually get a good night's rest with this mask.
Ordering: Price was great. Wasn't a large order, but it was shipped fast, and arrived before the expected delivery date. Nice!

I hate the way it rubbed against my tongue and the horrible dry mouth it gave me. My throat was so sore when I woke up.

No more leaks
5 out of 55 out of 55 out of 55 out of 55 out of 5
I tried several nasal masks and even with a silicon pad, still had breakthrough on the bridge of my nose. Tried a hybrid oral mask with nasal pillows and had huge leaks. The Oracle is small, light and seals beautifully. I have been using it for a week and a half and if you are comfortable with the mouthpiece (I used to scuba dive and snorkel) it's a winner.

I love this mask. Quiet - keeps the wife happy. No leaks. Great price. My first one lasted over a year and I was happy to purchase another at the great price on this site.

Great system-not for everybody
4 out of 54 out of 54 out of 54 out of 54 out of 5
I wanted to try this mask, because the one I am using puts a sore on my nose. This one seals perfectly around the mouth. It is a must that you have the heat moisture or your mouth will be the desert. I still have leakage out the nose so that will take tIme. If you have Big nose this will work better for you.

A good idea executed poorly
1 out of 51 out of 51 out of 51 out of 51 out of 5
I have chronic non-allergic rhinitis and compound obstructive/centralized sleep apnea. So naturally using breathing machines at night to sleep irritates my nose. I hoped this was a solution as it was the only mouth only mask I could find. I lost two whole nights of sleep trying to get this thing to work. The included in-nose plugs leaked and came out. Swimming style nose clamps solved that. However the mouth piece has limited adjustability and pieces. No combination produced a good seal. My entire face was wet with drool and I just couldn't get the mouth to seal no matter what I tried. There is no sleeping with this thing. No seal, leaks loud, makes your mouth blow farts all night.
