Qué considerar

01

Read the five-layer filtration as a barrier system

A KN95 respirator uses five layers of nonwoven filtration, including a melt-blown or HEPA filtration media that captures fine particles, dust and aerosols. The filtration media is what gives KN95 its high-efficiency rating, so the quality and basis weight of that media matter more than the total layer count. A well-formed melt-blown core is the first thing to check on a specification sheet.

  • Five-layer nonwoven construction
  • HEPA filtration media for fine particles
  • Melt-blown quality drives the protection level
02

Fit and seal decide whether the filter works

A respirator only protects if it seals against the face. Adjustable ear loops or head straps and a nose clip help achieve a secure fit, and a poor seal lets unfiltered air leak around the edges. For a respirator, the seal is as important as the filter — a high-efficiency media with a poor fit still lets contaminated air bypass the barrier.

  • A respirator only protects if it seals against the face
  • Adjustable straps and a nose clip improve the seal
  • A poor seal lets unfiltered air leak around the edges
03

Match the respirator to the task and the wearer

For healthcare and industrial settings where fine particles and aerosols are a risk, a KN95 respirator provides high-efficiency filtration. Consider the wearer too: a flat-fold design is convenient for storage and donning, a valve version reduces heat and moisture build-up for longer wear, and a smaller size fits children or smaller faces. Match the model to the task, the shift length and the wearer.

  • High-efficiency filtration for fine particles and aerosols
  • Flat-fold, valve and kids sizes suit different wearers
  • Match the model to the task and the shift length
04

Verify certification for the exact model

For export, confirm the KN95 carries the certification your market requires — CE for Europe and FDA registration for the US. The file must name the exact model you are ordering; a certificate that covers a similar but different respirator is not proof your order is compliant. Check the issuing body, the standard it meets and the validity period before you commit.
