About Micropore

Micropore, Inc. operates as a specialized manufacturer of advanced carbon dioxide (CO2) absorbent systems for critical life support and rebreathing applications. The company was founded in March 1997 by Doug McKenna, a former researcher at W.L. Gore, who identified a technology that fell outside his previous employer's core interests and developed it with their support. McKenna currently serves as the Chief Technology Officer.

The firm's core business revolves around its patented technology that transforms fine CO2 adsorbent powders into a solid, molded matrix. This process creates reactive plastic materials that are then formed into cartridges, representing a significant shift from traditional granular absorbents. The company markets its products under the brand names ExtendAir® and SpiraLith®, which are designed to offer superior performance, such as longer duration, easier breathing, and increased safety by eliminating the hazardous dust and potential for "caustic cocktail" formation common with loose granular products. This technology is positioned as the first major advancement in the field in over a century.

Micropore's business model is centered on selling these proprietary cartridges to a diverse range of high-stakes industries. Key markets include military (special operations rebreathers, submarines), medical (anesthesia, ventilators), and emergency response sectors like firefighting and mining safety. The company has secured significant contracts, with its absorbents being used by the US Navy, several NATO navies, and for emergency life support on submarines. For instance, the COVID-19 pandemic led to a surge in demand for its filtration materials for ventilators, prompting the company to increase its production capacity. Revenue is generated through the sale of these specialized absorbent products. The company is venture-backed, having raised capital from firms like Phoenix Venture Partners to expand its manufacturing capabilities.
