ResMed Mirage Activa LT Nasal CPAP Mask

ResMed Mirage Activa LT Nasal CPAP Mask

We recommend the ResMed Mirage Activa LT for active sleepers who move around a lot at night and want a nasal mask that resets itself instead of one you have to keep re-tightening. The ActiveCell cushion is a dual-wall silicone design that expands and contracts with your CPAP pressure and movement, so it holds its seal without you cranking down the headgear.

The MicroFit dial on the forehead support gives you 24 one-handed settings to fine-tune the fit: wind it in for a leak near the bridge of your nose, or out for a leak near your top lip. This is also the first mask in ResMed's ConvertAble Series, so the same frame accepts the Mirage SoftGel cushion if you'd rather try a gel seal without buying a new mask.

Therapy pressure runs from 4 to 20 cm H2O, and the mask is not made with latex, PVC, or DEHP. It comes in Small, Medium, Large, and Large-Wide: Small uses its own smaller frame, while Medium, Large, and Large-Wide share one standard frame. A prescription is required.

The headgear fastens with clips instead of magnets, so this is a magnet-free nasal mask worth discussing with your care team if you have a medical implant. Its compact, minimal-contact frame also tends to work well with facial hair and leaves your field of view open for reading or watching TV before bed.
