Fisher & Paykel

The Forma is yet another under-the-chin full face mask by Fisher & Paykel.

The Forma is the 3rd mask by Fisher & Paykel in an under-the-chin design which so many people appreciate when they're prone to their jaw falling during sleep.  To compare masks, see the FlexiFit 431, FlexiFit 432 (and Lowenstein also have a similar mask - the Joyce Plus).

Hope2Sleep's Observations:-

  • Fisher & Paykel really do work hard to cater for peoples individual facial structures, and with this 3rd under-the-chin mask they have also considered the bed partner too with the quieter air diffuser, and they've also designed this mask so that air isn't directed at either the patient or their partner.
  • Although the masks comes in 3 different sizes, the mask frame is one standard size, so any changes to cushion sizes will all fit on the same frame.  Additionally, for the most common sizes of medium and large there are actually both sizes of cushions in that pack.
  • There is now a more stable forehead support - particularly good for people who move around more in their sleep, and it has an auto-adjusting feature.
  • Another upgrade to their previous under-the-chin masks is the new FlexiFoam inner cushion for enhanced comfort and flexibility.
  • There is a quick-release cord which allows the patient to both remove the mask quickly and saves having to readjust the headgear for further use.

Fisher & Paykel say:-

  • The Forma Full Face Mask forms a superior seal and provides even more comfort with a greater range of movement through the active contouring of its new FlexiFoam Cushion.
  • The T-Piece adds stability to the stylized mask base, and works in harmony with the highly contoured Silicone Seal and Under-Chin Design to enhance sleep performance.
  • With its ease of use and superior conforming seal, the Forma sets a whole new standard.

I have been using a CPAP machine and mask of one sort or another for over 15 years and this is the first mask that not only fits but it actually very comfortable to wear! Well done F+P!

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.
