The elbow is configured to be removable when oriented to a predetermined position. The forehead pieces are provided in one or more sizes. The spacer fabric region comprises two or more layers wherein the raw edges are turned to the inside of the layers. The seal comprises features that improves seal performance and accommodates a wider variety of facial geometries. ## Claims ### Claim 1 A PAP kit comprising: an interface with a first seal having a first size and a second seal having a second size that is different than the first size, wherein the first seal and the second seal are each configured to form a seal around a user's nose and mouth,

edges of an opening of the respective seal, wherein a height of the second size is between 5.4% to 18.5% larger than a height of the first size, the height of the second size and the height of the first size each being measured along a center line of the respective seal between a midpoint in a chin region and a midpoint in a nasal bridge region, wherein the width of the second size is between 58.1% to 67.0% of the height of the second size. ### Claim 2 (depends on 1) The kit of claim 1, further comprising a frame, wherein the first seal and the second seal are configured to be removably and interchangeably connectable to the frame. ### Claim 3 (depends on 1) The kit of claim 1, further comprising at least one headgear, wherein the at least one headgear is configured to be removably and interchangeably connectable to the first seal and the second seal, or the at least one headgear comprises a first headgear configured to be removably connectable to the first seal and a second headgear configured to be removably connectable to the second seal. ### Claim 4 (depends on 1) The kit of claim 1, wherein the height of the first size is about 81 mm and the width of the first size

Sublabiale-Sellion height between 84.5 mm and 96 mm may be sealed by both the first size and the second size. ### Claim 11 (depends on 1) The kit of claim 1, wherein the width of the second size is approximately 11.9% greater than the width of the first size. ### Claim 12 (depends on 1) The kit of claim 1, wherein the width of the second size is approximately 1 mm to 11 mm greater than the width of the first size. ### Claim 13 (depends on 12) The kit of claim 12, wherein the width of the second size is approximately 6 mm greater than the width of the first size. ### Claim 14 (depends on 1) The kit of claim 1, wherein a difference between the height of the first size and the height of the second size is approximately twice a difference between the width of the first size and the width of the second size. ### Claim 15 (depends on 1) The kit of claim 1, wherein a difference between the height of the first size and the height of the second size is equal to or less than 9.5 mm. ### Claim 16 (depends on 1) The kit of claim 1, wherein a difference between the height of the first size and the height of the second size is equal to or less than 11.7%. ### Claim 17 (depends on 1) The kit of
