ActiveCell Technology

The ActiveCell design adapts to movement during sleep, which greatly reduces mask seal leaks. The extremely soft, and adjustable silicone membrane surrounding the dual-wall cushion. The cushion expands and contracts during breathing phase, and as a result, provides a remarkably effective seal. The ActiveCell membrane makes the Mirage Activa LT much less cumbersome than its predecessor. One of the real benefits of the ActiveCell is the ability to wear the mask very loose on your face. As a result, this reduces the overall pressure points of the mask, especially at the bridge of the nose.

MicroFit Dial

The MicroFit dial has 24 small incremental adjustments to allow you to adjust the mask for the perfect fit. Coupled with the dual-wall cushion, the forehead piece moves together as the dial turns. This feature addresses the challenges that can come with unique facial features.

Dual-Wall Cushions

The patented ResMed dual-wall cushion is tried and true, with being part of many of the ResMed CPAP mask lines. The Dual-Wall cushion provides a consistent seal while maintaining comfort. Greater comfort means better sleep.

Improved Diffusion Vent

The Activa LT is equipped with a newly designed diffusion port that disperses air quietly away from you, and your bed partner. The diffusion micro-port holes make for one of the quietest masks on the market.

Headgear Quick Clips

As with many of the ResMed Masks the breathoprene headgear for the Activa LT comes with quick clips. The quick clips make for fast and easy removal of the mask. This is particularly helpful if getting up in the middle of the night. Simply slip the mask and headgear off, and slip it back on again when returning to sleep.
