Preparing for the future of respirator fit testing

For safety and occupational health teams, maintaining reliable fit testing capability is essential for ongoing compliance and worker protection. As organisations look ahead, newer solutions such as AeroFit offer a pathway to modernisation while supporting continuity with existing fit testing practices.

What end-of-service timelines mean for current users

Widely used quantitative respirator fit testing systems have played an important role across industries including healthcare, construction, manufacturing, and emergency response. As some legacy systems approach end-of-support timelines, organisations may begin to encounter a number of operational and maintenance challenges, including:

• Reduced access to manufacturer servicing over time
• Increasing difficulty securing long-term calibration support
• Greater risk of downtime associated with ageing hardware components
• Potential workflow disruption if devices cannot be repaired or maintained efficiently

As equipment ages, maintaining consistent calibration, traceable records, and uninterrupted fit testing capability becomes increasingly important. This is why many safety professionals are proactively evaluating upgrade and transition strategies now, rather than waiting for support limitations or service gaps to affect operations.

Introducing AeroFit: a modern path forward

AeroFit has emerged as a next-generation fit testing solution designed for organisations planning beyond older particle-counting systems. Rather than requiring teams to adopt completely unfamiliar processes, AeroFit builds upon established fit testing principles while introducing updated hardware and software capabilities designed for modern respiratory protection programmes.

AeroFit key benefits

Organisations evaluating their next step are increasingly drawn to AeroFit for several practical reasons:

• Advanced APC technology
  AeroFit’s APC system is designed to deliver precise, repeatable, and stable fit testing performance, supporting high levels of accuracy and reliability.
• Modern, compact design
  Lightweight and portable, AeroFit is built for flexibility across both fixed and mobile testing environments, allowing convenient setup and operation.
• Quiet and efficient operation
  Engineered for low-noise performance, AeroFit is well suited to clinical, laboratory, and office environments where quieter operation is beneficial.
• Flexible battery-powered operation
  Optional battery functionality allows testing to be carried out in a wider range of environments, including locations without immediate mains power access.
• Standalone functionality
  AeroFit can operate independently without reliance on tablets, Bluetooth, or Wi-Fi connectivity, simplifying deployment and day-to-day operation.
• Streamlined system integration
  Shared accessories and compatibility with OHD Logic cloud software can help simplify equipment management and support operational efficiency.
• User-friendly touchscreen interface
  A clear colour touchscreen and intuitive controls are designed to improve usability and reduce operator training time.

Planning a smooth transition

For many organisations, evolving support timelines for legacy fit testing equipment represent an important milestone in long-term respiratory protection planning. While existing systems may continue to operate effectively for years to come, many teams are now exploring how to future-proof their programmes and reduce the risk of operational disruption.

AeroFit is positioned not only as an alternative platform, but as part of a broader modernisation strategy focused on usability, efficiency, and long-term sustainability. By planning ahead, organisations can help maintain compliance, minimise downtime risks, and support smoother operational continuity.

In many cases, the most practical approach is a phased transition strategy — continuing to operate existing systems while gradually integrating newer technology. This allows organisations to maintain continuity today while building a more resilient fit testing programme for the future.
