FAQ: CPAP Parts for the NoMask™ System

Do CPAP PRO® Nasal Puffs come in one size?

Our CPAP PRO® “No Mask” Systems include standard-size Nasal Puffs that fit the vast majority of users. A small percentage may prefer smaller or larger Nasal Puffs for the best seal. If the size you receive isn’t ideal, contact us at 1-800-538-8803 or use the Contact Us form with your order number, and we’ll send your first size-exchange pair at no charge.

What is the Boil-N-Bite Mouthpiece?

The CPAP PRO® uses a home-moldable (boil-and-bite) mouthpiece, similar to a sports guard, that conforms to your unique bite in minutes. Once fitted, it snaps onto your upper teeth (and onto both upper and lower teeth with CPAP PRO II®) and keeps the nasal interface aligned with your nose – so you can sleep in any position with fewer leaks, less skin irritation, and more stable therapy.

Do I have to clench my teeth all night to keep the mouthpiece in place?

No. After molding, the mouthpiece retains itself on your teeth—no biting or clenching required. It stays put while you sleep and releases with light pressure when you’re ready to remove it.

What if I tend to sleep with my mouth open?

Consider CPAP PRO II®, which features the Double Boil-N-Bite. It gently supports a closed-mouth position throughout the night – an excellent option for habitual mouth-breathers seeking better seal integrity and fewer dry-mouth issues.
