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

  • 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.

  • Able to be used with dentures
  • Improved patient comfort increases patient compliance

Will be returning this item, does not work for me.

Buckets of drool

This device will make you slobber and drool all over the place to where you hear bubbles in the mouthpiece while you breathe. It might work for some but as another user stated not good at all

Well made and I hoped for the best...

I use a P10 nasal cpap with a Fisher Paykel Cpap. I struggle with dry mouth so this oral cpap seemed to be the ticket. It is well made and I tried it for a week. Once I got it fitted and running it was good until I came close to sleep and my mouth relaxed. Then air came from my throat to my nose and was stopped by the nose piece. This and the fact the internal mouth piece would detach kept me awake. I was sorry to send it back in the 30 day return. I am still looking for a solution...

Missing a piece

I need to call and figure out what I'm missing

Good service by, but wearing mask was like licking and swallowing the Sahara Desert!

Such dryness can't be good for teeth and gums and throat!!! May be good in an extremely humid climate but certainly not in dry Colorado, even with my cpap humidity setting on 8!

A good idea executed poorly

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.

Great system-not for everybody

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.

Second one - wore out the first one!

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.
By EdbB,

No more leaks

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.

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.

Horrible Mask

By Mark,

Delivered early and 100% complete

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!
By Rick K,

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.
