You'll need your own CPAP machine and tubing. Prescription required.
A nasal mask covers the nose only, which many users prefer over a full face mask for its smaller footprint and lighter feel. The Activa LT adds a distinctive twist: instead of a cushion fixed rigidly to the frame, the cushion floats on a flexible membrane. As you move during the night, the cushion moves with you and re-seals — rather than breaking seal the moment your head shifts against the pillow.
The practical benefit is that you don't have to compensate by cranking the headgear tight. A looser, more comfortable fit that still seals is exactly what makes people stay consistent with therapy. The mask is also simple to live with: few parts, quick to take apart for cleaning, and easy to reassemble correctly.

The Activa LT cushion comes in several sizes, and the correct size is the one that seals around the nose without pressing on the nostrils or bridge. Use the ResMed Mirage Activa LT sizing guide, or contact us at (718) 735-3400 and we'll help you choose. Note: confirm which size corresponds to part 60148 before ordering.
What's included? The complete system — frame, cushion, and headgear.
What makes the Activa cushion different? The cushion floats on a flexible membrane, so it moves with you and re-seals as you change position — helping maintain the seal without tightening the headgear excessively.
Is a nasal mask right for me? Nasal masks suit people who breathe through their nose during sleep. If you tend to breathe through your mouth or often have nasal congestion, a full face mask may suit better — your provider can advise.
What machines does it work with? It connects to standard CPAP and BiLevel tubing from all manufacturers.
Which replacement parts does it use? The elbow assembly (16399) and cushion clip are shared with the Mirage SoftGel and Mirage Micro — convenient if you already stock those parts.
Do I need a prescription? Yes — a prescription is required in the U.S.
Can I get it delivered in Brooklyn or shipped nationwide? Yes — Task Supply Corp offers USPS shipping throughout the continental U.S., plus local pickup and delivery in Brooklyn and all five boroughs of New York City.
This is a prescription medical device. Use it according to the ResMed user guide and your healthcare provider's guidance.
