Nephros Inc (NASDAQ: NEPH)

Nephros Inc., a commercial-stage company with the ticker symbol NEPH, operates in the water solutions industry, specifically catering to medical and commercial markets. The company's primary business activities involve the development and sale of high-performance water filtration products. These products are designed for use in both medical and commercial applications, with the medical segment focusing on hospitals and dialysis centers, and the commercial segment serving food service, hospitality, and convenience store markets.

In the medical segment, Nephros provides ultrafiltration products that filter water and bicarbonate concentrate used in hemodialysis procedures. The company's medical products include the DSU-H and SSU-H, which offer dual- and single-stage protection from waterborne pathogens, respectively, and the S100, a point-of-use microfilter that provides protection from waterborne pathogens. These products are designed to capture contaminants as small as 0.005 microns in size.

In the commercial segment, Nephros offers the NanoGuard, an in-line ultrafilter that provides dual-stage retention of any organic or inorganic particle larger than 15,000 Daltons. The company also provides a line of commercial filters that improve water taste and odor, and reduce sediment, dirt, rust particles, and other solids.

Nephros operates in a competitive market, facing well-established companies such as Pall Corporation, 3M, and Pentair. However, the company has a competitive advantage due to its unique product attributes, such as its ability to filter waterborne pathogens, and its strategic partnerships with distributors and suppliers.

The company's customers include hospitals, dialysis centers, food service providers, and hospitality companies. Major customers accounted for 34% of the company's revenue in 2023.

Nephros' products are classified as Class II medical devices, requiring 510(k) clearance from the FDA. The company has received 510(k) clearance for several of its products, including the DSU, SSU-D/DSU-D, and OLpūr H2H Module and OLpūr MD 220 Hemodiafilter. In addition to FDA clearance, Nephros is also subject to European Union regulations, including the EU Medical Device Regulation (Council Regulations 2017/745). The company is currently seeking approval for CE certification under this regulation.

In addition to the FDA and European Union, Nephros is also subject to Canadian regulations, with the Therapeutic Products Directorate of Health Canada approving the company's OLpūr MD220 Hemodiafilter and DSU products for marketing. However, the company has not obtained any regulatory approvals to sell its products outside of the United States and the European Union, and there is no assurance that any such clearance or certification will be issued.
