Air Filtration in Commercial Respirators

CDI Engineering Solutions has teamed with Louisiana State University (LSU) to find better solutions for air filtration cartridges in commercial respirators/ventilators. Filter cartridges are required in both the intake and exhaust air systems of respirators. Most are prepackaged disposable filters produced by a very limited number of firms in Asia. Because of the sharp increase in demand for respirators in the COVID 19 pandemic, there is a shortage of the filter cartridges, leading to production shortages of respirators and replacement cartridges, reducing hospitals’ ability to care for sick patients.

Our goal is to identify an alternative for the exhaust filter cartridges that is readily available and cost-effective. CDI is working with LSU and ExxonMobil in Baton Rouge to develop potential solutions. CDI has supplied LSU with alternative media types for testing which uses readily available materials from suppliers in the US. So far, laboratory testing of the media has shown certain models and types to be 98% efficient in the filtration of exhaust air.

CDI is extremely proud to be part of the global effort to provide solutions and develop innovative responses to the pandemic that continues to upend societies and economies around the world.
