The Quantifit is the GOLD STANDARD in Respirator Fit Testing.  With the OSHA approved CNP REDON protocol, a fit test can be performed in as little as 2-3 minutes with no waiting period for smokers as required with other fit test methods. The REDON protocol uses CNP technology’s superior speed and accuracy to help achieve the best respirator fit possible.  Technicians and employees both prefer the Quantifit over other fit testers.
