KN95 vs N95: What's the Difference

Filtration efficiency, fit testing and regional standards — how KN95 and N95 respirators compare.

Was zu beachten ist

01

Filtration efficiency: same 95% target, different test methods

Both KN95 and N95 are designed to filter at least 95% of airborne particles, but they are verified under different test methods and standards. KN95 is tested to the Chinese GB2626 standard, while N95 is tested to the US NIOSH standard. The two standards use different test aerosols, flow rates and pass criteria, so a respirator that passes one is not automatically certified under the other. For procurement, treat the certification as market-specific rather than assuming cross-standard equivalence.

  • KN95: tested to GB2626 (China)
  • N95: tested to NIOSH (US)
  • Both target at least 95% particle filtration
  • Different test methods mean no automatic cross-certification
02

Fit and seal decide whether the rating protects

A respirator only protects if it seals against the wearer's face. The filtration rating is measured on a sealed test rig, not on a real face, so a poor fit lets unfiltered air leak around the edges and bypass the filter entirely. Fit testing is recommended to confirm the respirator seals for each wearer, and adjustable straps and a nose clip help achieve a secure fit. For a respirator, the seal is as important as the filter media.

  • The rating is measured on a sealed test rig
  • A poor fit lets unfiltered air leak around the edges
  • Fit testing confirms the seal for each wearer
  • Adjustable straps and a nose clip improve the seal
03

Regional standards decide which certification you need

The key difference between KN95 and N95 is regulatory. KN95 is certified under Chinese standards, while N95 is certified under US NIOSH standards. For the US market, confirm the respirator carries the appropriate FDA registration or NIOSH approval; for other markets, confirm the certification your target market accepts. Match the respirator to the certification your market requires rather than assuming one standard is accepted everywhere.

  • KN95: Chinese GB2626 certification
  • N95: US NIOSH certification
  • Match the certification to your target market
04

Which should you choose?

Choose based on your market and certification requirements, not on the name alone. Both offer high-efficiency filtration, so the deciding factor is usually which certification your target market accepts and which model fits your wearers. Confirm the respirator carries the certification for your market, verify the file names the exact model you order, and match the model to the task and the wearer.

  • Decide by market certification, not the name
  • Verify the file names the exact model you order
  • Match the model to the task and the wearer
