Part 3: Fitting the half mask 😷
A well-fitted mask is essential for reliable respiratory protection.
Follow these simple steps:
1️⃣ Put on the mask
Place the mask over your mouth and nose, then connect the second side to the Y-hose.
2️⃣ Adjust the straps
Position the head harness and tighten the chin cord, followed by the head and neck straps until the mask fits snugly and comfortably.
3️⃣ Fine-tune the fit
Tighten or loosen the face straps as needed. Adjust the head straps to position the mask correctly on your face.
4️⃣ Check the nose seal
The mask should sit flat on the bridge of your nose. If needed, the replaceable nose pad can be trimmed along the marked lines for additional space.
5️⃣ Perform a fit check
Turn the blower off and take two deep breaths. The mask should gently pull against your face. If it doesn't, readjust the straps until you achieve a secure and comfortable seal.
💡A proper fit helps ensure maximum protection every time you use your swiss air.
