Puraffinity is a science-driven technology company developing advanced adsorbent media, branded as Puratech, specifically designed to remove PFAS (per- and polyfluoroalkyl substances, often called "forever chemicals") from water.[1][2][5] It serves residential, commercial, industrial, municipal, and environmental service sectors by addressing the global PFAS contamination crisis, offering broad-spectrum removal, up to 7 times longer lifespan than traditional ion exchange resins, fast kinetics for smaller system footprints, and adaptability to existing water treatment systems.[1][5][7] The company solves the limitations of existing technologies like granular-activated carbon and ion exchange, which are non-selective and struggle with regulatory compliance, aiming to provide PFAS-free water to 1 billion people by 2030 amid tightening global regulations.[2][4][7]
Puraffinity's growth momentum includes its first commercial agreement in July 2025 with Envytech Solutions for full-scale deployment of Puratech G400, following successful field pilots that reduced contact times from 24 minutes to 1 minute in real-world contaminated groundwater.[7] This milestone validates years of R&D and positions the company for broader rollout across industries and geographies.[7]
Puraffinity was incorporated in 2015 as a spinout from Imperial College London, focusing on designing smart materials for environmental applications, initially targeting PFAS removal.[2][3][4][6] Co-founder and former CEO Henrik Hagemann, along with a multidisciplinary team of scientists and engineers from diverse backgrounds, drove the company's ethos of using deep science to tackle environmental threats like PFAS, inspired by rapid life sciences advances during the pandemic.[4][8] The idea emerged from recognizing gaps in current PFAS removal technologies, leading to a patented platform that engineers raw material surfaces with "PFAS-friendly" molecular groups for high selectivity.[4][5]
Early traction built through R&D on bespoke adsorbents, culminating in Puratech's development for versatile applications from household filters to large-scale systems.[1][6] Pivotal moments include field pilots confirming real-world performance and the 2025 commercial deal, marking the shift from pilots to deployment.[7]
Puraffinity rides the surging wave of PFAS remediation driven by global regulatory crackdowns—such as U.S. EPA limits and EU restrictions—creating urgent demand for effective, compliant water treatment as contamination from AFFF firefighting foams and industrial sources affects billions.[1][4][7][9] Timing is ideal amid water scarcity in urbanizing populations and post-pandemic emphasis on science-led environmental solutions, where legacy methods fail on selectivity and efficiency.[4][8]
Market forces like rising compliance costs and sustainability mandates favor Puraffinity's compact, cost-efficient tech, influencing the ecosystem by enabling greener operations for partners like Envytech and accelerating PFAS-free water access worldwide.[2][7] It exemplifies green tech innovation from academic spinouts, blending materials science with commercialization to reshape water treatment standards.[2][3]
Puraffinity is poised for scaled commercialization post its landmark 2025 deal, with Puratech G400 expanding to more pilots, municipal contracts, and global markets amid intensifying PFAS bans.[7] Trends like stricter regulations, AI-driven materials discovery, and decentralized water tech will propel growth, potentially hitting the 1 billion people goal through partnerships and residential products.[2][9]
Its influence may evolve from niche innovator to market leader, driving industry standards for sustainable remediation while inspiring multidisciplinary green tech ventures—ultimately delivering cleaner water where legacy solutions fall short.[1][4]
