Air Techniques International (ATI) has been a global leader in the design and manufacture of specialized testing equipment for HEPA filters, media, filter cartridges, respirators, and protective masks since 1961. 

The 100X Automated Filter Tester is designed to test and validate filter media, cartridges and masks used in medical and industrial hygiene applications. The 100X can be used to test any grade of media up to and including HEPA and ULPA grade media. The 100X uses an oil or salt aerosol challenge to measure and report filter efficiency and resistance of the media or filtering piece. The 100X is available with either an oil (DOP, PAO) or salt (NaCl) aerosol generator, depending upon the intended application and offers three flow rates to meet customer needs. Additionally, ATI has a long history of working with customers to develop custom test fixtures and inserts to satisfy their testing needs. The 100X meets several global industry standards including NIOSH 42 CFR Part 84 (the spec for N95 respirators), GB 2626, JICOSH/JMOL, and many others. The 100X is widely used by leading media manufacturers and filter manufacturers around the world. The most common applications are found within Quality Assurance, R&D, and Production environments. The 100X is ideal for testing N95 respirators that are widely being used to help prevent the spread of the COVID-19 virus.
