## Article Body
Follows U.S. EPA's April 2026 decision to include microplastics as a priority contaminant group under the Safe Drinking Water Act's draft Contaminant Candidate List

Company underscores relevance of advanced filtration in addressing one of the fastest-growing concerns in water quality

SOUTH ORANGE, N.J., June 16, 2026 (GLOBE NEWSWIRE) -- Nephros, Inc. (Nasdaq: NEPH), a leading water technology company providing filtration solutions to the medical and commercial markets, today highlighted the capability of its ultrafiltration technology to effectively capture microplastics and nanoplastics before they enter the water, reinforcing the Company’s position at the forefront of emerging water quality and safety challenges.

This announcement follows the U.S. Environmental Protection Agency's April 2026 decision to include microplastics as a priority contaminant group under the Safe Drinking Water Act's draft Contaminant Candidate List (CCL 6), a significant milestone that underscores growing regulatory attention to plastic particle contamination in drinking water.

Microplastics are plastic particles ranging in size from 1 micrometer to 5 millimeters, while nanoplastics are smaller than 1 micrometer. There is a growing body of scientific evidence* that nanoplastics pose an even greater risk to human health than microplastics, however most filtration technologies are not designed to address both micro- and nano-plastics.

Nephros’ ultrafiltration products are engineered with pore sizes as small as 5 nanometers, well below the threshold for plastics, enabling size-based exclusion of particles that may pass through conventional filtration technologies. As a result, Nephros filters are also effective in physically retaining not only bacteria and viruses but also microplastics and nanoplastics.

“As regulatory and scientific attention shift to microplastics and nanoplastics, the need for proven, high-performance filtration solutions becomes increasingly urgent,” said Robert Banks, President and Chief Executive Officer of Nephros. “Our ultrafiltration technology was designed to support contaminant retention at a level that is directly aligned with this emerging concern. We believe this capability further differentiates Nephros in both healthcare and broader water quality markets.”

Nephros views this trend as part of a broader evolution in water quality management, where customers are moving from reactive solutions to more proactive, precision-based approaches. Nephros’ ultrafiltration platform is well-positioned to support this transition, offering scalable solutions that address both known and emerging risks.

About Nephros Nephros is committed to improving the human relationship with water through leading, accessible technology. We provide innovative water filtration products and services, along with water-quality education, as part of an integrated approach to water safety. Nephros products serve the needs of customers within healthcare and commercial markets, offering both proactive and emergency solutions for water management.
