Real-World Comfort
Designed for All-Day Comfort
Proprietary nose foam and a pleated structure help reduce pressure points while maintaining comfort and a stable fit throughout extended wear. Refined using feedback from clinicians at HealthShare NSW for real-world healthcare environments.

Blood Splatter Testing
Level 3 Fluid Resistance
ZERO surgical masks are tested for resistance to synthetic blood penetration at 160 mmHg, supporting Level 3 fluid resistance for clinical and professional use.
Nano-Fibre Technology
>99.9% Bacterial Filtration Efficiency
ZERO surgical masks are tested to ASTM F2101 for Bacterial Filtration Efficiency, demonstrating >99.9% filtration against bacterial aerosol challenge.
Meaningful Reduction In Landfill Waste
Biodegrades in Landfill Conditions
Designed to work within existing landfill waste streams, approximately 74–90% of the product mass is biodegradable under landfill conditions, depending on the model. Biodegradable components achieved approximately 53% biodegradation in around 700 days under simulated landfill conditions.
Adaptive Structure
Pleated Construction That Moves With You
The pleated structure expands and contracts naturally with facial movement while maintaining comfort, shape, and consistent everyday wearability.

Secure Fit
Secure Head-Tie Design
The adjustable head-tie system provides a stable fit while reducing concentrated pressure around the ears during extended periods of wear.

Clinically Informed Design
Refined Through Years of Real Clinician Feedback
Developed through multiple rounds of clinician feedback within HealthShare NSW environments, focusing on real-world comfort and fit preferences. Designed to perform consistently across extended wear in demanding settings.
FAQS
Find answers to commonly asked questions.
What standards do these masks meet?
All masks are certified to AS 4381:2015 for fluid resistance and filtration.
Visit our Certifications page to view test results.
Are they latex-free?
Yes, all FILTRUM masks are independently tested for latex and meet the requirements for a latex-free claim. Visit our Certifications page for test results.
Are they single-use?
Yes, all FILTRUM masks are designed for single use to ensure maximum hygiene.
How do I dispose of my FILTRUM Mask?
Once a FILTRUM mask or respirator has been used, it can be disposed of in a standard general waste stream, consistent with typical PPE protocols. What differentiates FILTRUM is what happens after that point.
Where possible, any paper-based packaging can be separated and placed into standard recycling streams.
