How to Wear a Medical Flat Mask Correctly: Adjusting the Double Steel-Strip and Nose Press
If your mask slips or feels like it leaks air, the issue is often the adjustment—not the mask itself. Follow this step-by-step guide to calibrate the double steel-strip and nose press for a better fit.
1) Confirm the right size first
This product’s adult flat size is 17.5 x 9.5 cm. If it feels too tight or too loose, the fit won’t improve much even with perfect adjustment.
2) The calibration steps (easy and repeatable)
Put on the mask first, then gently press the nose-press strip in sections, and finally fine-tune the contour using the double steel-strip so both sides sit evenly.
3) Troubleshooting: slipping, leakage, and discomfort
Upper leakage often comes from insufficient nose-press shaping. Slipping can be related to contour not being fixed or size mismatch. Ear discomfort can be caused by twisted or overly tight ear loops.
4) A quick checklist you can use every time
After adjustment, check for leakage sensation during normal breathing and ensure the ear loops are not twisted before you start your day.
