About StrionAir

Founded in 1997, StrionAir Inc. operated as a developer and manufacturer of specialized air purification systems. The company's technological foundation was based on research conducted at Lawrence Livermore National Lab, which led to patented methods for enhanced electronic filtration.

StrionAir's core business involved producing air purification systems for both commercial and residential applications. The company's client base included government buildings, hospitals, laboratories, schools, and general commercial facilities. A significant milestone was a supply agreement starting in 2006 with Carrier Corporation for its Infinity Air Purifier, which eventually led to StrionAir's acquisition by Carrier on August 31, 2009. Prior to its acquisition, the company had successfully sold over 6,000 commercial systems. Financially, StrionAir secured a total of $15.5 million in funding across three rounds from institutional investors such as The Carlyle Group, Sequel Venture Partners, and Solstice Capital.

The company's product, the StrionAir System, integrated mechanical filtration, electrostatics, and ionization to achieve high-efficiency air purification, rated at MERV 16. The system works by first passing contaminated air through an ionization array, which lends an electrical charge to airborne particles. These charged particles are then captured by a polarized, disposable filter element, where they are destroyed through a combination of ionization and oxidative stress. This process was third-party validated to not only capture but also kill pathogens like bacteria, viruses, and mold, a key differentiator from standard HEPA filters. The design also offered energy efficiency benefits by maintaining a lower pressure drop compared to traditional filtration technologies, which could lead to savings on HVAC energy consumption.
