Nephros Targets Puerto Rico's Water Crisis with $10M Expansion

SOUTH ORANGE, N.J. – February 13, 2026 – Water technology firm Nephros, Inc. has announced its expansion into Puerto Rico, a strategic move that brings its specialized filtration solutions to an island long beset by critical water quality and infrastructure challenges. The company is targeting a market it estimates to be worth $10 million, aiming to provide safeguards for essential applications in healthcare, foodservice, and hospitality.

The Nasdaq-listed company’s entry into Puerto Rico is more than a simple business expansion; it represents a direct response to a well-documented public health vulnerability. By focusing on point-of-use filtration for everything from hospital sterile processing units to hotel ice machines and drinking fountains, Nephros is positioning itself as a crucial last line of defense in a system under constant strain.

An Island Thirsty for Solutions

Puerto Rico's struggle with water is not new, but it has been catastrophically highlighted by recent history. The island's aging infrastructure, characterized by decades of underfunding and corrosion, has proven profoundly vulnerable. The devastating impacts of Hurricane Maria in 2017 and Hurricane Fiona in 2022 exposed the fragility of the system, leaving millions without safe drinking water for extended periods due to power outages, contamination from flooding, and damage to treatment facilities.

Even without a hurricane, the challenges are persistent. According to historical U.S. Environmental Protection Agency (EPA) data, Puerto Rico has had the highest rate of drinking water violations in the United States, with a staggering 70% of the population once served by systems that failed to meet federal health standards. Boil water advisories are a common feature of daily life for many residents.

The contaminants are varied and serious. Lead, a potent neurotoxin, is a significant threat, with studies showing its presence in a high percentage of water samples. This is largely due to the prevalence of older housing and service lines installed before lead-based plumbing was banned. Furthermore, “forever chemicals” like PFAS have been detected in water systems across the island, prompting federal investment to address the emerging contaminant. This is compounded by frequent microbial contamination, including coliform bacteria and the risk of severe illnesses like leptospirosis, particularly after heavy rainfall or system failures.

While the Puerto Rico Aqueduct and Sewer Authority (PRASA) manages the bulk of the island's water supply, its systemic challenges mean that water delivered to a building may still pose a risk by the time it reaches the tap. This gap between municipal treatment and point-of-use safety is precisely the niche Nephros intends to fill.

A Calculated Move into an Underserved Market

Nephros executives have identified Puerto Rico as a prime opportunity, not just for growth, but to apply its technology where it is most needed. The company’s $10 million market estimate is broken down across key sectors: $3 million in healthcare, $3 million in foodservice, $1 million in hotels, and another $1 million in other hospitality venues, with the remainder projected from service contracts and filter replacements.

“We believe Puerto Rico is a massively underserved market when it comes to reliable, high-quality filtration—particularly for environments where bacteria and harmful contaminants in water can have serious consequences,” said Robert Banks, President and CEO of Nephros, in a statement. “Our entry into Puerto Rico is a natural extension of our core strategy: leveraging best-in-class technology and execution to meet critical water safety needs.”

This expansion is also a key part of the company's broader plan to move beyond its traditional focus on patient care filtration and into adjacent commercial markets. The same technology used to protect immunocompromised patients in hospitals can be applied to ensure the safety of hotel guests and restaurant patrons, protecting both public health and the reputation of businesses in Puerto Rico's vital tourism industry.

Redefining Service with a Local-First Approach

For Nephros, conquering this market isn't just about superior technology; it's about superior service tailored to the island's unique context. The company plans to differentiate itself from potential competitors by establishing a robust local presence, a strategy designed to overcome the logistical hurdles that have long plagued businesses in Puerto Rico.

Key to this approach is a promise of rapid response and fulfillment, made possible by a dedicated, on-island inventory network. In a region where supply chains can be easily disrupted by everything from port congestion to hurricanes, having replacement filters and parts available locally is a significant competitive advantage. This eliminates long waits for shipments from the mainland, reducing downtime for critical equipment in hospitals and businesses.

Furthermore, Nephros is committing to on-site installation, scheduled filter replacements, and, crucially, customer support and technical documentation in Spanish. This localized, language-specific support is designed to build trust and ensure clear communication, acknowledging the cultural and linguistic realities of the Puerto Rican market. This model stands in contrast to mainland-based companies that may try to serve the island remotely with less sensitivity to local needs.

“We’re inspired by the momentum, energized by the cultural pride, and ready to serve,” Banks added. “This market launch underscores our belief that small, agile companies with the right technology and team can create meaningful impact even in complex, fragmented markets.”

From Sterile Labs to Hotel Lobbies: Fortifying Critical Points of Use

The tangible impact of this expansion will be felt at the final point of water delivery. In healthcare settings, Nephros’s filters are designed to provide an essential barrier against waterborne pathogens like Legionella in plumbing outlets and ensure the ultra-pure water required for sterile processing departments, where medical instruments are decontaminated. For a healthcare system still recovering and rebuilding, such safeguards are indispensable for infection control.

In the hospitality and foodservice sectors, the focus is on both safety and quality. The company's filtration solutions for ice machines, drinking fountains, and bottle fillers are designed to remove not only microbial threats but also regulated contaminants like lead and PFAS, ensuring that water is safe for consumption. For an economy heavily reliant on tourism, ensuring the health and confidence of visitors is paramount. A single water-related illness outbreak could do significant damage to a hotel's or restaurant's reputation.

By providing a reliable, verifiable layer of protection at the tap, Nephros aims to give businesses and healthcare providers control over their water quality, independent of the daily fluctuations in the municipal supply. This move represents a significant private-sector investment in the resilience of Puerto Rico’s public health infrastructure and its commercial backbone.
