Medical Mask Testing Requirements
What is medical mask?
Medical mask is a loose-fitting, disposable mask that is considered as medical device. It is fluid resistant and designed to protect wearers from large droplets such as blood, splashes, or sprats of bodily or other hazardous fluids. Wearer’s mouth and nose will be covered to create a barrier for minimizing the direct transmission of infective agents.
Medical mask is mainly categorized into two types: non-sterile and sterile. The former is intended for use by patients or other wearers, the latter is intended for use by healthcare professionals in medical settings. Both types of medical mask are subject to strict regulations in different countries before being made commercially available.

Key test parameters
While there are many testing parameters for measuring the quality and performance attributes of medical mask, below are key testing parameters to take note of:
Test Parameter | Test Objective | Measurement |
Bacterial Filtration Efficiency (BFE) | Resistance of the mask against bacterial agents | Results are reported as percentage efficiency rating. The higher the number in this test indicates better barrier efficiency |
Particle Filtration Efficiency (PFE) | Resistance of the mask against particles larger than 1 micron | Results are reported as percentage efficiency rating. The higher the number in this test indicates better filtration efficiency* |
Fluid Resistance Testing | Resistance of the mask against liquid splashes such as blood or other bodily fluids | Results are reported as pressure with or without any fluid penetration observed at the back side of mask. The higher value without penetration indicates better fluid resistance. |
Breathability Testing – Differential Pressure | Easiness of the wearer to breath comfortably in the mask | Lower breathing resistance indicates a better level of comfort for the wearer |
Microbial Cleanliness | Total number of viable micro-organism on the mask | Results are reported in units of micro-organism, lower the value higher level of cleanliness |
*higher filtration efficiency usually indicates a greater difficulty for air to pass through the mask. In this case, breathability testing is recommended.
