Respirator Fit Testers

Respirator Fit Testing for the Highest Level of Protection

In many of today’s workplace environments, a respirator and a proper respirator fit test are critical components of employee respiratory protection. Fire service and law enforcement employees, as well as industrial companies and healthcare professionals have come to depend on properly fitting respirators for protection from respiratory hazards, such as chemical and environmental hazards, as well as airborne biohazards.

When implemented correctly, a respirator fit testing services program can help ensure that the highest respiratory protection levels are achieved through a properly sized and donned respirator.

Easy… Accurate... Repeatable…

The PortaCount® respirator fit testing equipment measures real-time fit while the user simultaneously performs a series of moving, breathing and talking exercises designed to simulate the same movements made in the field. The step by step process is guided via the FitPro+™ Fit Test Software and stored in a database for easy report generation, retrieval and regulatory compliance. The stored data is easily transferrable via a flash drive.

  • Passing a real-time quantitative respirator fit test proves that the facepiece is sized and donned correctly, as well as provides for valuable opportunity for training. The PortaCount Respirator Fit Tester tests all types of respirators, including N95 filtering facepiece respirators.
