The N95-Companion works with the PORTACOUNT Plus to provide you with a complete solution to all of your fit testing needs. Use the PORTACOUNT alone for masks equipped with series-99 and series- 100 filters. Add the N95-Companion to fit test masks with series-95 filters, including the popular N95 filtering-facepiece disposables. You can switch back and forth between different respirator types in minutes.

The easy-to-use FitPlus™ for Fit Test software, which comes with every PORTACOUNT, automates the fit test, prints the results and maintains a database for permanent record keeping and report generation.
