Argonide Corporation

Argonide Corporation, founded in 1994 by Fred Tepper and headquartered in Sanford, Florida, develops and manufactures nanofiber-based water filtration media originally conceived under NASA SBIR contracts for spacecraft water recycling. The company's core technology, NanoCeram, employs a thermally bonded non-woven matrix of microglass and cellulose fibers infused with 2-nanometer alumina nanofibers that captures submicron particles through electropositive adsorption rather than mechanical pore-size exclusion. This approach achieves greater than 99.99% efficiency at 0.2 microns (latex spheres) with a dirt holding capacity of 82 grams per square foot — roughly 100 times that of conventional media — while maintaining high flow rates and low pressure drop. NanoCeram filter cartridges are available in VS, PAC, PB, PACB, DP, and LR series configurations with optional powdered activated carbon and antimicrobial Agion treatments, and hold NSF/ANSI 42 and 53 certifications. Argonide's DEAL technology applies an electropositively charged alumina coating to diatomaceous earth, achieving 7-log bacteria and virus removal for potable water applications. The CoolBlue point-of-entry whole-house system is certified to NSF P231 at 8 GPM. Additional products include EPA Method 1615-compliant virus samplers and custom filter engineering services. The company operates under ISO 9001 certification and licenses its nanoalumina fiber technology worldwide through Ahlstrom Filtration, serving residential, commercial, and industrial markets including RO prefiltration, HVAC and Legionella control, food and beverage processing, and municipal drinking water.
