About Accutec

Accutec makes fit testing straightforward, dependable, and backed by science, so the people responsible for respiratory protection can focus on what matters most.

Who We Are

Who We Are

Accutec is a manufacturer of quantitative respirator fit testing instruments, purpose-built to help safety professionals run stronger, more defensible respiratory protection programs. Founded on the belief that fit testing technology should be accessible and reliable, Accutec developed the AccuFit™ series using proven CNC technology recognized by OSHA, ANSI, CE, and CSA.

Today Accutec serves hospitals, fire departments, industrial operations, government agencies, and fit testing service providers across North America and beyond. Our focus has always been singular: build fit testing equipment that works when it needs to and stand behind it.

What We Do

Quantitative fit testing devices
