Purified Water for Cleanrooms

High-purity DI and USP-grade water for cleaning, rinsing, and process support in critical environments.

Purified water is a quiet but essential part of contamination control. Cleanrooms use high-purity water because ordinary tap water carries ions, organics, particles, and microbes that can leave residue, create spots, or introduce variability into sensitive processes. Instead, facilities rely on deionized (DI) / high-purity water for general cleanroom cleaning and rinsing, and USP Purified Water (PW) or Water for Injection (WFI) when regulated manufacturing demands defined pharmacopeial quality.

In day-to-day practice, purified water is used to dilute cleaners and disinfectants to validated strengths, rinse surfaces after detergent or sporicidal steps, and perform final wipe or rinse cycles where residue control is critical. Semiconductor and microelectronics environments also depend on DI water for particle-free wafer and component cleaning, where ionic or mineral carryover can impact yield. In pharmaceutical and biotech cleanrooms, USP PW supports non-parenteral manufacturing and equipment cleaning, while WFI is reserved for parenteral/aseptic operations and final rinses because it has tighter microbial and endotoxin limits.
