Swift LT Nasal Pillow CPAP Masks & Accessories

The Swift LT line from ResMed built its reputation on one idea: a nasal pillow mask should be so light and quiet that you barely notice you're wearing it. For people who breathe primarily through the nose and want the least amount of hardware on their face, the Swift LT remains a benchmark — minimal headgear, a soft dual-wall pillow that seals with gentle pressure, and an open sightline that lets you read or watch TV before drifting off.

This collection gathers the replacement parts that keep a Swift LT performing the way it did new. Nasal pillows are the piece that wears fastest — silicone softens and loses its seal with nightly use — so most users replace them every few weeks to a month, while headgear and frames typically last longer. If you're seeing air leaks, whistling, or red marks in the morning, worn pillows or a stretched-out strap are usually the culprit rather than the mask itself.

Sizing matters more here than on many masks: nasal pillows come in small, medium, and large, and the right fit is the one that seals without you having to overtighten the headgear. Many users keep a spare set of pillows in a second size on hand, since nasal passages can feel different from one night to the next.

If you're comparing options within the ResMed nasal pillow family, it's worth looking at the newer Swift FX, which refined the frame and headgear, or the earlier Mirage Swift II that preceded this design. Full-mask and other CPAP interfaces such as the King LT(S)-D serve different needs entirely.

Check your mask's model marking before ordering — Swift LT parts are specific to this system and won't interchange with Swift FX or Mirage Swift components.
