Mask Size Guides
Choosing the right size matters — an ill-fitting mask leaks, leaves marks, and is the number-one reason people give up on CPAP. Each mask family is sized differently, so use the guide for your mask. Tap any guide to enlarge it.
Hybrid Mask
YF-06
The YF-06 is sized with a card you print at home, not a tape measure. Print the guide at 100% scale, check it against the two calibration marks, then cut out the card.
Hold the card vertically against your face under your nose, sit the base of your nose in the groove, and read off the coloured band that covers both your nostril sides and nose tip.
Sizes S · SW · M · MW · L (SW and MW are wider cushion variants)

Printing: Set your print dialog to Scale: 100% or Actual Size — not "Fit to Page". The sheet has a 100 mm ruler and a bank-card outline so you can confirm it printed at true scale before using it.
Nasal Masks
YN-02 / YN-03
Measure the width across the base of your nose, from nostril to nostril, with a ruler held horizontally against your face. Match your measurement to the closest size.
Sizes S · M · L
