Fisher & Paykel

Unfortunately the Oracle Mask has now been discontinued all our stock is gone. 

The Oracle Oral 452 CPAP Mask by Fisher & Paykel is the only mask of this type, being a mouth-only mask.  It will not suit the majority of people, but has come to the rescue of a big enough majority to warrant continuous supply.

Please consider before purchase that this mask will not suit the majority of mask users, despite being a successful option for certain people.  Also read our 'Important Tips' further down this page.

The Oracle Mask has now been discontinued, and all our stock is sold.

Hope2Sleep's Observations:-

This unique Oracle Oral 452 Mask by Fisher & Paykel is for mouth breathers as it delivers the CPAP or non-invasive ventilator air through the mouth only.  We believe this is the only mouth-only mask available on the market, and whilst it is not suitable for the majority of people, Fisher & Paykel are renowned for not often withdrawing older or less popular masks from the market in their efforts to help as many patients as they can.

The type of people that may find this Oracle Oral mask a good alternative are people with severe nasal obstructions and those who struggle to nasal breathe.  Scuba divers have been known to have very good success with this mask.

This is the latest upgraded version of the Oracle 452 mask as Fisher & Paykel have worked at making it as comfortable as possible.

There are 2 sizes of the mouthpiece supplied in order that people can find the best fit for them and the mouthpiece is designed to be positioned in front of the teeth with the outer SnapFlap sealing over the lips.

The Bias Diffuser Filter is to prevent both noise from the mask and to help direct the air away from a bed partner and the Headgear consists of just one strap and there is also an easy-release cord attached to remove the mask quickly.

Fisher & Paykel say:-

The unique Oracle™ 452 delivers pressure through the mouth rather than the nose.
Clinically proven to function as effectively as a nasal mask (in suitable patients), the Oracle™ 452 is a perfect solution for mouth breathers and patients with chronic nasal obstruction.
  • The Oracle™ 452 Oral Mask is easy to use and easyto seal. 
  • With nothing covering the field of vision, the Oracle™ 452 provides freedom of movement.
  • The Oracle™ 452 Oral Mask comes as an Out-of-Box Solution - fully assembled and ready for use.

There is no sizing template for this Oracle 452 mask as both mouthpiece sizes are included, and nasal plugs are also included if it is found air is escaping through the nose.

Important Tips:-

  • It is strongly advised that a heated humidifier be used with this mask as it will, for most people, cause a dry mouth.  Even with humidification this can happen, and in which case people may need to use Xylimelts or XyliGel to lubricate the mouth during sleep (or something similar).

  • As previously stated, this mask is not suitable for the majority of mask users, but it can be a successful option for people with chronic nasal obstructions.  It should be noted, that nasal breathing is far healthier for us all, but for people who simply cannot nasal breathe through their nose then this may be worth trying.  However, please read everything carefully before opting for this mask due to the fact that masks cannot be exchanged once the packets are open.

  • Never attempt to use this mask with no or very low pressures.

  • Fisher & Paykel advise using the supplied nasal plugs for at least the first 2 weeks to train yourself not to allow air to escape through the nostrils.

  • The small FlexiTube measures 5 inches so for people requiring one of our Mini Hose Covers to insulate it to help with 'rainout' from the humidifier or just to warm up the air slightly, then the 8 inch one will be fine and will ruffle up to actually provide more insulation.

Iím sure this product works perfectly well for most people but when I wear it my mouth fills with saliva which, because of the way the mask fits I have trouble swallowing. I do keep trying to see if I can get used to it but not yet.

Sorry the Oracle hasn't worked well for you. It's certainly a mask that only suits the minority of people who are going to be disappointed as the mask is going to be discontinued.

Oracle 452 CPAP Mask
20 July 2022  | 

First time I have ordered from hope2sleep. Speed of delivery was excellent from ordering to arrival at my door was less than 48 hours.
I also found the cost good compared to other providers. Will now use hope2sleep for my other CPAP supplies

I bought this as an alternative as I suffer really bad with nasal problems and I'm a mouth breather and found this mask very comfy. If I'm honest I couldnt even tell I had a mask on. I didnt even after wear strap as it fits snug no restrictions I slept 9hrs. I never used to sleep past 7 hrs with full mask as it always woke me up.
(It's like having gum shield in). Would I recommend this mask? Yes if you're ok having the feel of gum shield in. I would recommend watching few Youtube videos with clearer demonstrations as that's how I decided to try it. Best thing I've bought and no more issues for me in hayfever season x

We try our best to ship all orders received by us Monday-Friday on the same working day if received before 12 noon, and more often than not orders processed before 3pm will be despatched the same day whenever possible.  Weekend or UK bank holiday orders are sent out the next working day.  An automated email is sent when products have been despatched so please check your spam box and add us to your safe senders list.  Also, if you do not receive an email confirmation, please check that you have typed the correct email address in your account.

All orders are sent via 1st class mail within the UK.  Masks and some other more expensive products are always sent via 'signed for' insured delivery and cannot be left in 'safe' places, but there is the option for an alternative shipping address when processing the orders. 

Delivery charges are worked out automatically by weight and you can clearly see the delivery charges before making a payment.  On the rare occasion delivery charges are miscalculated by the website, a refund will be sent, as it is not our policy to make money on postage charges and neither do we add the cost of delivery into the price and offer so-called  'free delivery' like some sites and Ebay pressurise sellers to do! 

Wherever possible with larger parcels, we try to re-use boxes to keep shipping costs down and protect the environment.

If a product is out of stock and the order contains multiple items, the 'in stock' items will be sent immediately and further items will follow upon arrival with no further postage charges incurred.  

Important for International Orders

We can ship most products internationally, but all prices are in UK British Pounds and if paying by debit or credit card the bank will automatically convert to the current conversation rate.  Likewise, if you choose the Paypal option, they will convert into your currency for you as payment is made.  

International orders are sent via tracked Airmail, and whilst we're happy to ship internationally, we cannot be held responsible for any delays at Customs at your end, or charges that may be added in your own country, such as customs fees and import tax on delivery, which are determined by your country’s import laws and are beyond our control. Therefore, it is the customer’s responsibility to pay these charges, and certain courier companies will not be able to deliver the goods to you without pre-payment of any charges. From our experience, it appears to be randomised as to which parcels incur extra charges, but please know that all accompanying paperwork is filled in correctly when shipping and there is nothing more we can do, as much as we'd like to.

If you purchase from us out of the UK or you move to another country after purchasing products, please be aware that the warranty for CPAP machines, masks and parts from the manufacturers are under warranty  with the manufacturer based in the UK, so you will be responsible for sending the product back to us and will need to pay postage to get the product back to you after exchange or repair, as the manufacturer will not pay for shipping in any country outside of the UK.


Masks, CPAP machines and and most other products are exempt from a refund or exchange unless faulty due to health and hygiene issues - as stated in our 'Terms and Conditions', and in particular due to the risk of cross contamination as they cannot be re-sold. The Consumer Contracts Regulations 28.(3)(a) confirms exemption as follows:-  "exemption in the case of a contract for the supply of sealed goods which are not suitable for return due to health protection or hygiene reasons, if they become unsealed after delivery."

Unopened (sealed) products in their original packing can be returned within 14 days for a refund of the product cost, but the purchaser is to pay the return postage, and we would advise retaining proof of postage. This excludes any faulty goods, for which postage will be reimbursed.  A full refund for the price of the product will be issued when received by us, less the original postage charges when the order was sent to you.



Most of the products we sell are eligible for Zero Rated VAT in the UK, and in order to qualify, you should meet the criteria for the following HMRC VAT Declaration:-

  1. You or the person you are purchasing on behalf of have "a condition that the medical profession treats as a chronic sickness, that is a long term health condition" (sleep apnoea and sleep disordered breathing, which require therapy, are such conditions).
  2. "The goods or services are for the personal or domestic use of the customer."

Please note, you do not need to be registered as disabled or in receipt of any other benefits in order to be eligible for VAT relief - you only need to meet the criteria of the above 2 points.

We cannot advise on individual cases, but more information can be found on HMRC’s website under notice 701/7 on the following link

If you are not eligible for Zero Rated VAT then please make sure that the VAT Relief box in unticked so that VAT is applied to the order.

If you are purchasing on behalf of someone else who meets the above criteria, you must provide their name and address, and you will be prompted of this during the checkout process.

Customers living outside of the UK do not pay UK VAT charges, so please leave the the VAT Relief box ticked.  However, we cannot be held responsible for any additional costs incurred when the products reach your own country.

If you are purchasing with the intention of re-selling any products, you are liable to pay VAT on all products so you must untick the 'zero rate eligibility' box which will add VAT to your order.

Any products that our not eligible for zero rate VAT, will not display the VAT Declaration, and VAT will be added at checkout.
