FlexiFit HC406 Petite Overview
The FlexiFit HC406 Petite Nasal CPAP Mask with Headgear is a mask designed with small faces in mind. The HC406 is available only in one size: Petite.
Specifically designed to fit finer featured faces, the HC406 Petite Nasal CPAP Mask merges flexifit technology with auto-contouring properties. The HC406 comes with a unique Glider Strap mechanism and a Stretchgear Headgear for maximum comfort and stability. A maintenance-free bias diffuser ensures quieter operation.
The headgear of the HC406 is latex free, as are all other headgear by Fisher & Paykel.
The HC406 comes as an out of the box solution, fully assembled.
This is the HC406 mask, especially designed for those with very fine features.
Where do I find the size?
The FlexiFit HC406 is the petite size nasal CPAP mask. The bottom of the mask frame is labeled with the mask name: HC406. When examining the front of the mask, the name is printed below the glider strap. The FlexiFit HC406 cushion is replaceable, but there are no identifiable marks on the cushion or flap. The size of the cushion reflects the size of the mask frame.

Any mask will work with any machine, with one important exception. The ResMed AirMini is only compatible with certain ResMed CPAP masks. Compatible masks for the AirMini are as follows:
- ResMed AirFit™ N20 Nasal Mask
- ResMed AirFit™ F20 Full Face
- ResMed AirTouch™ F20 Full Face
- ResMed AirFit™ P10 Nasal Pillow
When considering another CPAP, APAP or BiPAP machine from ResMed or any other manufacturer, mask compatibility extends to all brands. The AirMini uses non-standard tubing to connect the machine to the mask, and is the primary reason why other masks won't work with the AirMini. Despite this issue, many of our customers consider the AirMini to be an excellent machine.
Help Me Choose - Mask
In our experience, most mask cushions begin to deteriorate after about six months of use. The cushion eventually becomes too soft to hold a seal. The headgear straps lose elasticity and must be tightened more and more to get the same quality seal.
We strongly suggest replacing cushions and pillows as soon as they start to soften. Air leaks may reduce the effectiveness of CPAP therapy and headgear that is too tight may cause facial sores at pressure points. In most cases, replacement headgear is available if it is stretched out or the Velcro worn out.
To see what parts of your mask are replaceable refer to our Replacement Part Finder. Just search for your mask to see all of the replaceable parts.
Masks should be washed daily with warm water and gentle soap or baby shampoo. Let the mask air dry. Never use antibacterial soap as it will break down the silicone of the mask cushion. Avoid soaps that include lotion which can coat the mask and cause it to lose its seal. A safe cleaner is the Control III Disinfectant CPAP Cleaning Solution. Remember, going to bed with a clean face will improve your seal and protect the lifespan of your mask.
The best time to clean your mask is in the morning after use. This removes the oils left behind from your skin which can reduce the lifespan of your mask. We recommend using Mask Wipes to make daily morning cleaning easy. The mask wipes are made from materials that will not break down your mask.
For customers who want to completely disinfect their mask and accessories, there's an even better option than wipes. The Lumin Mask and Accessories Cleaner uses powerful UV light to disinfect, killing almost all bacteria almost instantly. It's not a cleaner and doesn't scrub or wash anything, but for simple disinfecting the Lumin works great!

- Sizing Guides. Many Nasal and Full Face masks have sizing guides available to help determine the size needed. Simply print the sizing guide, cut out if needed, and use a mirror or helper to look at the guide to see if it is a proper fit on the face. Please note, to ensure the guide is the proper size, it should be printed in PDF format at 100% scale, meaning "Fit to Page" may have to be disabled.
- Return Insurance. With every mask we sell, you have the option of purchasing return insurance. Masks are FDA approved medical devices. Once a mask is used, it cannot be resold to another customer. CPAP.com was the first in the industry to offer return insurance to our customers. Return insurance provides 30 days for you to try a mask and return it for any reason for a refund of the price of the mask. If you are trying a mask for the first time, return insurance might be right for you.
We also offer Free Return Insurance on some masks.

HC406 Nasal Headgear
I bought this for my husband and it is working great. great fit
I have learned not to be too thrilled about a new mask since I bought a gel nasal mask a few months ago. It was great until a week passed and it then began to dig into the bridge of my nose causing bleeding. So.....this Flexfit HC 406 seems fine and seals well but I have only used it for a few days. Time will Tell! more...
The CPAP mask was a perfect fit. Very comfortable to wear.
It was what I needed, a back up mask. Good price.
I've tried all of the nose masks, and this one is the best. Most compfy and I can even sleep on my side. more...
