Advancing Respiratory Protection: The Engineering Task Force

Overview

The COVID-19 pandemic revealed a stark truth: respiratory protection standards and designs lagged far behind the needs of healthcare workers and the public in emergency settings. Recognizing this gap, I conviened and led the Respiratory Protection Engineering Task Force (RPETF)—an international collaboration of engineers, scientists, and medical professionals dedicated to improving mask design, testing, and deployment.

Purpose and Goals

The Task Force was established to answer urgent questions:

• How effective are existing respirators and masks in real-world pandemic conditions?
• What engineering principles can make protection more reliable, comfortable, and scalable?
• How can we improve respiratory protection?

By drawing together expertise across disciplines—mechanical engineering, fluid dynamics, materials science, clinical medicine, and public health—the group aimed to create an evidence base for safer, more effective respiratory protection systems during the COVID-19 pandemic.

Why It Mattered

Respiratory protection is not just a technical challenge; it is a cornerstone of pandemic preparedness and occupational safety. Yet at the start of COVID-19, the world was unprepared. The RPE sought to protect the public and healthcare workers by:

• Testing emergency designs for respirators
• Documenting real-world issues, from fit failures to filtration limits, that compromised user safety.
• Providing open-access findings to policymakers, hospitals, and manufacturers to guide immediate improvements.

The Task Force’s work emphasized that effective masks are not only about filtering particles but also about usability, scalability, and adoption.

Key Outcomes

Through coordinated studies, workshops, and publications, the RPETF achieved several concrete outcomes:

• Comparative evaluations of respirator and mask designs, identifying both critical weaknesses and best-in-class solutions.
• Emergency respirator designs, for individuals who had no access to commercial respirators, including civilians around the world in healthcare workers in developing nations‍
• Recommendations for innovation, such as improved seal designs, alternative materials, and scalable production methods.‍
• Frameworks for testing and validation that can inform future standards and product development.‍
• Knowledge dissemination via the Face Mask Research hub, providing resources for engineers, healthcare professionals, and the public.
