Founded by John H. Erbland, Rochester-based Paradigm Emissions Technologies designs and manufactures patented plasma pollution-control systems that remove particulate matter from diesel and gasoline engine exhaust. Its compact pass-through reactors are built for both fleet retrofits and integration into new engine designs, helping protect EGR and aftertreatment components while reducing fuel and maintenance costs. The company received a $256,000 National Science Foundation SBIR grant in 2022 to advance plasma-reactor research for high-temperature diesel exhaust.

AirFlow Catalyst Systems, IncFounded in 1997 around catalytic-converter materials, AirFlow Catalyst Systems develops and manufactures low-temperature emissions-control systems for diesel and other compression-ignition engines. Its chemistry-centered work is aimed especially at mining and marine equipment, with internally managed development and application-specific designs rather than a one-size-fits-all system. The company also produces custom washcoats and coatings, drawing on a proprietary formulation based on a NASA license.ROCHESTER, NY
Ward Diesel Filter SystemsEstablished in 1987, Ward Diesel Filter Systems is a fire-service-focused manufacturer known for its apparatus-mounted approach to exhaust protection. President and owner Scott Beecher purchased the company in 2013, and the company now supports fire departments and emergency fleets with NO SMOKE systems that travel with the vehicle rather than relying on fixed station connections.HORSEHEADS, NY
Air Clear LLCSince 1991, Air Clear LLC has built its identity around solving difficult industrial emissions problems from its Maryland facility. The company designs custom air-pollution control equipment for manufacturers worldwide, with in-house fabrication and factory testing that carry projects from early engineering through installation and long-term support. Its systems have served demanding operations such as textile production, oil refining, and chemical processing.ELKTON, MD
IPD Products, IncPennsylvania-based IPD Products, Inc. develops active air-sterilization systems that use its PlasmaFence™ cold-plasma technology to destroy or neutralize airborne pathogens. The company began in a small incubator focused on developing plasma energy technology and is now led by engineers and scientists with patents spanning high-energy physics, chemistry, and applications aimed at improving health outcomes.WARMINSTER, PA
