US Reverse Osmosis System Market to Reach USD 3.53 Billion by 2032, Growing at a CAGR of 5.36% During 2026–2032

The U.S. Reverse Osmosis System Market was valued at USD 2.45 billion in 2025 and reached USD 2.58 billion in 2026, with projections to attain USD 3.53 billion by 2032, expanding at a CAGR of 5.36% during the forecast period of 2026–2032. Growth is primarily driven by the U.S. Environmental Protection Agency's National Primary Drinking Water Regulation, finalized on April 10, 2024, which established enforceable Maximum Contaminant Levels of 4 parts per trillion for PFOA and PFOS.

Furthermore, commercial and institutional demand is strengthening through strategic corporate investment. On January 6, 2026, A. O. Smith Corporation completed its USD 470 million acquisition of Leonard Valve Company, expanding its integrated water management and purification portfolio for hospitals, schools, and institutional facilities across North America and reinforcing broader industry consolidation.

As a result, Point-of-Use (POU) systems lead the market with approximately 76% revenue share, supported by compact design and rising PFAS-driven adoption, while Thin Film Composite (TFC) membranes capture approximately 92% share of the membrane material segment owing to superior salt rejection and chemical resistance. These segment dynamics are expected to sustain long-term market expansion through 2032, as stated in the recent report “US Reverse Osmosis System Market Analysis, 2026”.
