Hypochlorous (HOCl) Generator

How does it work?

Making disinfectant is easy. Just fill the pitcher with water and add kosher salt. Power on the system and within minutes a cleaner and disinfectant is generated called hypochlorous (HOCl) also known as electrolyzed water.

Alternatively a cleaner and degreaser can be generated by substituting kosher salt for food grade potassium carbonate.

Why is system quality important?

Since the start of the COVID-19 pandemic, many low quality hypochlorous generators from China have flooded the market. Below are some key points to consider before making a purchase:

Titanium Electrolysis Cell

The cell must be manufactured with a high grade titanium coating. Systems using electrolysis cells that are manufactured from lower quality alloys will deteriorate quickly and may not generate hypochlorous. If the electrolysis cell is made from steel or other lower grade metals, the electrolysis cell will deteriorate very quickly and will generate harmful chromium compounds that can be carcinogenic.

Size of the Electrolysis Cell

Our electrolysis cell is relatively large for a 1 Liter pitcher and only requires 2 grams of salt to generate 200 ppm of hypochlorous. Even higher concentrations can be generated if the system is run for extra cycles. Many low quality systems manufactured in China are requiring very large quantities of salt. If you see that the directions on a system require 5 to 20 grams of salt per Liter, you can be sure that the electrolysis cell is very small and your solution salinity will be extremely high. Most likely the system is generating sodium hypochlorite (NaOCl) and not hypochlorous (HOCl).


Concentrations up to 200 ppm of hypochlorous (HOCl)

  • Production Rate: 
  • 1 Liter at 200 ppm in 10 minutes
  • Oxidation Potential of Anolyte (HOCl): 
  • +800 to +1000 mV

Concentrations over 400 ppm of hypochlorous (HOCl)

After generating 200 ppm, if you continue to run additional cycles, each additional cycle will raise the concentration approximately 80-100 ppm.

Expected lifespan of system

The electrolysis cell is manufactured in titanium and has a typical lifespan of 3,000 cycles (8 minutes each).

What about the salt for making HOCl disinfectant?

You will need to purchase non-iodized food grade salt at your local supermarket (ie. kosher salt).

What about the potassium carbonate for making KOH degreaser?

A 100 gram sample of food grade potassium carbonate is included, enough to generate 50 liters of degreaser.
