There are so many types of medical masks—how do you know which one is right?

In the post-pandemic era, masks remain a key part of daily protection. But with discomfort from long hours of wear and worries about proper protection, choosing the right mask matters more than ever. This guide walks you through everything from mask structure and filtration efficiency to certification labels and comfort design, helping you choose a mask that’s truly safe and wearable.

Understanding the 3-Layer Structure of a Medical Mask

 

  • Outer Layer –Water-Repellent Nonwoven Fabric

Blocks droplets and moisture, keeping the surface dry and protecting the filter layer.

  • Middle Layer – Melt-Blown Nonwoven Fabric

The key filtration layer. Its fine fiber structure traps bacteria and airborne.

  • Inner Layer – Soft, Hydrophilic Nonwoven Fabric

This skin-contacting layer must be soft and non-abrasive, providing comfort even after long hours of wear.

Why Melt-Blown Fabric Is the Heart of a Medical Mask?

The real protection in a medical mask comes from the melt-blown middle layer—not the thickness.
GRAMINTON ’s medical masks comply with CNS14774 standards and achieve ≥95% Bacterial Filtration Efficiency (BFE) to deliver reliable protection.

  • Ultra-Fine Fibers:

The melt-blown layer forms a dense web that blocks bacteria without restricting airflow.

  • Electrostatic Charge:

The filter layer is electrostatically  treated to enhance its ability to trap microscopic particles.

  • Not Washable:

Washing breaks down the electrostatic charge and reduces filtration. For safety, medical masks are single-use only.

How to Identify a Qualified, Comfortable Medical Mask

With so many masks on the market, make sure you’re wearing a certified medical mask that offers true protection. Here’show:

STEP 1: Look for the “Double Mark” on the Mask

Since Sept 24, 2020, all made-in-Taiwan flat medical masks must show the “MD” and “Made in Taiwan” marks on the mask surface—proof of medical-grade quality.

STEP 2: Check the Outer Box for the Medical Device License

Only products with a valid license number issued by Taiwan’s Ministry of Health and Welfare are considered genuine medical devices. You can verify license numbers through the TFDA online database.

STEP 3: Ensure Compliance with CNS14774 Standards

  • BFE ≥ 95% – Proven bacterial filtration.
  • SGS-Certified Materials – No azo dyes, formaldehyde, or fluorescent agents.

STEP 4: Check The Comfort Factor: Small Details Make a Big Difference
