LiquiTech® Copper-Silver Ionization

The LiquiTech® Copper-Silver Ionization System is an innovative, chemical-free disinfection solution for potable water systems. It’s designed to quickly destroy Legionella and other waterborne pathogens and achieve long-term prevention without creating harmful byproducts or damaging plumbing equipment.

Why Copper-Silver Ionization?

  • Highly effective regardless of water temperature or complexity of plumbing system
  • Outperforms chemical and oxidative alternatives in controlling waterborne pathogens
  • Provides complete system disinfection within 48 hours
  • Does not dissipate rapidly in hot water for lasting protection


  • Effective: Copper-silver ionization technology is proven effective in a wide range of water conditions, temperatures, and plumbing systems, consistently outperforming chemical or oxidative alternatives to control waterborne pathogens.
  • Fast results: Our Copper-Silver Ionization System can achieve complete system disinfection in as little as 48 hours.
  • Lasting protection: Copper and silver ions provide lasting protection against waterborne pathogens. They do not dissipate quickly in hot water like chemical solutions do. Plus, they easily penetrate biofilms, destroying pathogens inside to prevent future recontamination.
  • Safe and sustainable: Copper and silver ions are safe for human consumption, do not create harmful byproducts or carcinogens, are not corrosive to plumbing, and do not require water shut-off, public health department notice, or storage of hazardous chemicals.
  • Self-controlled: Equipped with smart technology, our system modulates ion output based on current water conditions, ensuring ion concentrations are always aligned with water usage.
  • Remotely monitored: A remote monitoring system tracks and logs system data 24/7, providing real-time diagnostics, alarm notifications and resolutions, and documentation required to maintain compliance with regulatory agencies.
  • Backed by science: Hundreds of independent research studies have identified copper-silver ionization as the most effective disinfectant against Legionella, with additional studies showing its effectiveness against other harmful bacteria and fungi, like Pseudomonas, Acinetobacter, Nontuberculous Mycobacteria, and Steontrophomonas.
  • Certified: The LiquiTech® Copper-Silver Ionization System is EPA-registered for Legionella control at the federal level and in all 50 states, is NSF Standard 61 certified, and approved by the ETL/UL and CE.

Case study

Hospital Legionella-free for 30+ years

After a Legionella outbreak and several months of remediation attempts with chlorine, Lucile Packard Children's Hospital Stanford partnered with LiquiTech to install a Copper-Silver Ionization System. The hospital achieved non-detect levels for Legionella and has remained Legionella-free for more than 30 years.
