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

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.

Couldn't handle the dry mouth it creates...

Not a fan of the Oracle 452 Mask
1 out of 51 out of 51 out of 51 out of 51 out of 5
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!

Bad Mask

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.
