Hassle-free, easy to fit and comfortable, the Mirage Activa™ LT is made for CPAP users who hate fussing with their mask every night. Fit it once and enjoy a comfy, secure seal. Best for restless sleepers. Improvements include the MicroFit dial, new compact ActiveCell™ technology, new diffusion vent and a dual-wall cushion that now comes in four sizes. The overall design is streamlined to be a smaller, quieter and better performing nasal mask than the original Activa™.
