no matter what the brand

Trade-in your existing respirator fit tester (ours and/or our competitors) and get a CREDIT towards the purchase of a new PortaCount® Pro or PortaCount Pro+ Fit Tester. Both models make fit testing even faster and easier; plus the new PortaCount Pro+ fit tester has built-in N95 fit testing technology.
