What We Do

At Breathe Medical Manufacturing Ltd., the quality of the products we produce is paramount in our production process. Utilizing in-house state-of-the-art testing equipment ensures that we meet national and international standards.

We test raw materials coming in and finished products going out in the 5 key measures of Bacterial Filtration Efficiency, Particle Filtration Efficiency, Synthetic Blood Penetration, Differential Pressure, and Respiratory Resistance.

What We Offer

We provide testing services to health care, government and private sector organizations who wish to ensure the products they have meet the standards they require.

Whether you would like testing performed on raw goods from your suppliers before you start manufacturing or you would like to test samples of finished goods, we can assist to ensure your supplier is providing you products that meet national and international standards.


ASTM International is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. Membership comprises of individuals and organizations in over 140 countries worldwide.

Bacterial Filtration Efficiency

The Bacterial Filtration Efficiency (BFE) test is used to measure a material’s resistance to penetration of bacteria. Our processes uses microbial aerosol liquid spray producing results as percent efficiency and correlating with the ability of the fabric to resist bacterial penetration. This test is performed on filtration materials such as air filters, face masks, surgical gowns and caps that are designed to protect against biological aerosols.

This test is used for FDA and Health Canada submissions and complies with ASTM F2100, ASTM F2101 and EN 14683.

Particle Filtration Efficiency

The Particle Filtration Efficiency (PFE) test is used to measure a material’s filtering retention against particles. This test is performed on filtration materials such as air filters and face masks that are designed to protect against particle aerosols. Latex Particle Challenge and NaCl.

ASTM F2100
ASTM F2299

Synthetic Blood Penetration

The Synthetic Blood Penetration or Splash Resistance test is used to measure the resistance of the masks ability to act as a barrier against blood or other liquids. The test uses different levels of synthetic blood volumes directed at high velocity to determine the resistance.

ASTM F1862
ASTM F2100
EN 14683
ISO 26609

Differential Pressure

The Differential Pressure test is used to measure the breathability of masks. Our process is testing through measuring the differential pressure required to draw air through a measured surface area at a constant air flow rate and to test the air exchange pressure of the medical face mask material, which indicates the breathability.

ASTM F2100
EN 149
EN 14683
GB 2626

Respiratory Resistance

The Respiratory Resistance test is used for determining the inhalation resistance and exhalation resistance under the regulations of respirators and masks.

GB 2626
GB/T 32610
