ZERO™ Level 3 Surgical Mask Head Ties
The ZERO Surgical Mask is an AS 4381:2015 Level 3 medical face mask designed for clinical environments, delivering >99.9% bacterial filtration efficiency, L3 fluid resistance, reliable protection and all-day comfort.
Engineered for secure, breathable protection, it combines high-performance filter media with soft lightweight materials, low breathing resistance and a clinician-friendly tie-back design for a customisable fit. A malleable, conformable nose wire with soft nose foam helps create an effective and comfortable seal across the face.
Made with biodegradable nonwoven elements that support accelerated biodegradation in landfill conditions, ZERO is designed to help reduce the waste associated with disposable PPE.

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
Shaped by HealthShare NSW 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.
