Read the three-ply construction as a barrier system
A surgical mask is not a single filter — it is a three-layer barrier. The outer spunbond layer resists fluid splash, the melt-blown middle layer is the true filter that captures bacteria and particles, and the soft inner layer sits against the skin. The melt-blown layer's basis weight and quality drive the mask's protection level, so a heavier, well-formed melt-blown core is the first thing to check on a specification sheet.
- Outer spunbond layer resists fluid splash
- Melt-blown middle layer filters bacteria and particles
- Soft inner layer for comfort against the skin
- Melt-blown basis weight drives the protection level
