Wide Face The value will be marked 'Yes' for CPAP masks with interfaces that are unique to CPAP users with wide facial features. Masks with 'Wide' cushion sizes would fall under this category.

Facial Hair These CPAP masks have interfaces that accommodate a wide variety of facial hair styles. Gel cushions and foam inserts provide support and comfort for users who may need to over-tighten headgear straps to help seal around facial hair.

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 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 silicone eventually becomes too soft to hold a seal and headgear straps 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. You can also replace the headgear of your mask 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. Search for your mask and then see all of the replaceable parts.

Why do I wake up with dry eyes?

Air leaking from the mask at the bridge of the nose and over the eyes during sleep will cause the eyes to dry out. The most common reason for air leaking at the nose bridge is that the mask is too big or too long for the nose.

We would suggest you resize your mask to be sure you have the best size. A mask that has an adjustment at the bridge may also be helpful in getting a good fit. Nasal pillow or nose cushion devices which do not rest on the nose are also an option.

It is not advisable to tighten the headgear to eliminate the air leak. Pressure from a mask that is too tight will cause bruises and even open sores if applied long enough.

How do I care for my mask?

Masks should be washed daily in warm water with baby shampoo and left to air dry. Never use antibacterial soap as it will break down the silicone of the mask. Avoid soaps with lotion or lanolin which can coat the mask and cause it to lose its seal. A safe cleaner is the Control III Disinfectant CPAP Cleaning Solution. Remember to go to bed with a clean face, this will improve your seal and protect the lifespan of your mask.
The best time to clean your mask is in the morning so that the oils from your skin are removed. We recommend using mask wipes to make daily morning cleanings easy. The mask wipes are made from materials that will not break down your mask.

What does a mask prescription need to say?

• Contains 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"
• Contains physician's contact information
• Contains physician's signature
• Contains the patient's full name

Are prescriptions required for mask, machine and/or humidifier purchases?

Yes. Federal law requires we have a valid prescription on file before we ship your mask, machine and/or humidifier.

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

Why might I need a full face mask?

If your mouth drops open during sleep, a full face may be selected to allow for the CPAP airflow to be delivered through both the nose and mouth.

Some CPAP users move to using a full face mask after finding that using a nasal mask along with a chinstrap does not meet their sleep therapy needs. Some CPAP users use a full face mask when suffering from seasonal allergies.

Are the FlexiFit HC431 and HC432 cushion sizes interchangeable on the mask frame?

All FlexiFit HC431 and HC432 cushions and mask frames are interchangeable. The silicone cushions are interchangeable, but the foams will not work with the 431.
