The TrueBlue gel nasal mask with Auto Seal is designed to deliver a higher degree of comfort, stability, and freedom of movement with minimal adjustments.

Headgear has inlaid adjustable straps that converge into a single back panel with a crown strap for added stability.

Premium blue gel works together with the thin, form-fitting outer silicone membrane to create an effective, self-adjusting seal. Not only does the TrueBlue's blue gel provide extra stability, it is thinner and lighter than ever before.

Freeform spring gives you the ability to move in any direction. The soft silicone spring helps you to get a better night's sleep by limiting disturbances to the seal.

Intuitive forehead pad is designed expressly for the TrueBlue CPAP mask and is enhanced with a remarkably soft premium blue gel.

Angled exhalation micro ports make operation quieter and they redirect air away from a bed partner.

Talon quick-release headgear clips are included with the TrueBlue CPAP mask, making it easy for you to remove the mask and "lock in" the same fit, night after night.

Sizing information
The sizing of the TrueBlue corresponds to sizing for the ComfortGel and ComfortGel Blue nasal masks. In addition to the petite, small, medium and large sizes, the TrueBlue offers a medium wide size. The medium wide is good for people who are between a medium and a large in the ComfortGel or ComfortGel Blue. The ComfortGel nasal mask sizing chart is listed below, with corresponding TrueBlue part numbers.

Don't know which size to order? Use our mask sizing guide below to help you decide which size is best for you. To use the guide you'll need to take the following two measurements:

1. Measure straight down from the middle of your pupil to the bottom of your nose. It may help to imagine a horizontal line extended from your nose to beneath your eye, so that you can measure straight down from your pupil.
2. Measure the width of your nose at its widest point

You should purchase the CPAP mask that most closely matches the measurements you take, being sure to make sure that the CPAP mask dimensions are no smaller than the measurements you took. It's better to have a slightly large CPAP mask than one that is too small.
