Unique Inner Foam Cushion Gives You the Freedom to Move Without Impacting Your Seal

The unique foam cushion shape provides a secure seal while the Glider Strap Anti-Leak System helps maintain the seal regardless of your favorite sleep position. The unique glider strap connects the headgear to the mask frame and forehead rest and slides across the frame as your head turns for more adaptability during CPAP therapy.

Front Swivel Hose Connection Permits Motion in Any Direction

Since it can be positioned in any direction, the front swivel hose connection provides the ability to move around as you sleep, providing a better, more active fit for greater comfort. The sliding strap and front swivel hose make the FlexiFit 405 ideal for active sleepers.

Headgear Offers Stability and Unobstructed View

The latex-free headgear doesn’t feature a fifth headgear strap, offering an open line of sight to let you watch T.V. or read without compromising stability - even with fewer straps.

Improved Diffuser System for an Even Quieter Mask

Redesigned and reconfigured on the elbow of the swivel, the exhalation vent of the FlexiFit 405 nasal mask prevents therapy air from blowing on you and your bed partner. The added filter helps reduce noise.

  3. Wash the silicone seal and the headgear in lukewarm water and mild soap.
  4. Rinse all parts thoroughly in clean drinking water.
  5. Set aside to air dry, but don’t place in direct sunlight.

Help with Sizing

For help with selecting your size, please review the FlexiFit HC405 Fitting Guide.

For help with fitting directions, please review: HC405 Mask User Manual.

Where do I find the size?

The FlexiFit HC405 Nasal CPAP Mask is a mask frame that comes with two nasal cushion sizes: small and large. The bottom of the mask frame is labeled with the mask name: HC405, representing the necessary mask frame needed if the user wears a size small or size large. When examining the front of the mask frame, the name is printed below the glider strap.

The FlexiFit HC405 cushion is replaceable, and it has an identifiable mark. To find the size of the nasal cushion, locate the flat bottom of the mask. Embossed in silicone, the user will see the word small or large. Depending on the word recorded on the bottom of the nasal cushion, the replacement cushion will need to correspond directly. The HC405 cushions can be viewed here: Flexi Foam Cushion Insert and Silicone Seal Kit for Aclaim 2 and HC405 Nasal CPAP Mask.

Which CPAP masks work on which machines?

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.

Do you have a guide to help me choose the right mask?
Yes, we created a Help Me Choose guide to help you select the right mask or machine according to your preferences. The guide asks you a series of questions regarding your preferences and your facial features. Based on your answers we provide you with a comparison chart of the masks that meet your criteria. Get started here:

Help Me Choose - Mask
How often should I replace my mask?
Medicare allows for mask cushion replacement every three (3) months, and a complete mask system replacement every six (6) months. CPAP manufacturers and vendors suggest these replacement schedules as well.

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.
What does a mask prescription need to say?
A mask prescription must contain all of the following information:
  • One of the following words or phrases: "CPAP Mask", "CPAP Supplies", "CPAP Humidifier", "CPAP", "Continuous Positive Airway Pressure", "APAP", "AutoPAP", "AutoSet", "Auto CPAP", "Auto Adjusting CPAP", "Self Adjusting CPAP", "BiPAP", "BiLevel", "VPAP", "BiPAP Auto", "BiPAP ST", "Synchrony ST", "VPAP ST"
  • Your physician's contact information
  • Your physician's signature
  • The patient's full name

Are prescriptions required for mask, machine, humidifier, and EPAP purchases?

Yes. Federal law requires we have a valid prescription on file before we ship your mask, machine, humidifier, or EPAP therapy, including Provent and Bongo RX. You will also need a prescription to purchase the Nightbalance POSA device.


We provide many easy ways to get your prescription:

  • We can request your prescription for you! When you checkout, just let us know you would like us to request your prescription, or you can log into your account to have us request your prescription.
  • Fax your prescription to our toll-free fax number: 866.353.2727, or our international fax number: 713.541.7377
  • Email your prescription to cpap@cpap.com
  • Upload your prescription in your account, under the Prescriptions Section
  • Ask your doctor to fill out our prescription form. We have both a standard prescription form and an EPAP prescription form.


For more information on prescriptions, please see our Prescription Section of the Learning Center.


Why might I prefer a nasal mask?
The ideal CPAP mask is not noticeable to the user during CPAP therapy. If you breathe through your nose only, the nasal mask may offer the best therapy. Nasal cushions create a very good seal around your nose, while keeping a small profile. Also, nasal masks can be found in silicone, gel, foam, or cloth material. The SleepWeaver masks are the only cloth masks on the market, and are a very popular choice among nasal mask users. Lastly, most nasal masks have a forehead support which offers stability and support for the mask.

What are the CPAP, BiPAP, Sleep Apnea, and Oxygen related HCPCS, CPT or billing codes?

E1399 is Miscellaneous and is used for other CPAP and Oxygen items.
How do I care for my mask?

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. Citrus Mask Wipes

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.

Citrus Mask Wipes


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!

Not Very Comfortable

Verified purchase | Oct. 17, 2022 | Verified CPAP.com Customer
I ordered this since CPAP.COM was out of the Comfort Gel masks I usually get and they had no idea when they would be back in stock. Comparatively, this mask if far less comfortable than the Comfort Gel and more expensive. It does work, I expect to live with it until the velcro wears out (the life limiter of all masks), I won't buy another and will consider switching vendors if the Comfort Gel isn't available here.

Solid CPAP Face Mask

Verified purchase | Jan. 07, 2020 | Verified CPAP.com Customer
A very good full nasal CPAP mask. I have used this model for about five years and now am buying replacement parts - particularly the double elastic around the back of the head. With regular wear and cleaning the elastic lasts about one year, then begins to lose elasticity. If you can manage sleeping with a fairly large apparatus on the front of your face, this model mask is an excellent choice. I have not tried any of the nose plug type masks, so cannot compare to them.
