Hypoclorous Acid and the important role PH plays in it

It was brought to my attention the concept of using HOCl with a humidifier. In theory, it seemed like a great idea. So I started doing some digging on the issue. We even found some suppliers that could source us a 2 in 1 machine, that acts both as a HOCl generator and humidifier all in one (generates the HOCl as it disburses it.

After doing some research, this is not a practice we would recommend, and not a product we would want to deal with.

The reason is as follows. While I had mentioned in a previous post, that a high PH can cause the HOCl generator to produce Hypochlorite, (household bleach), if the PH is too low, it can create CL2 or Chlorine Gas, which can be extremely dangerous.

HOCl is the form that CL2 takes when it is dissolved in water, it is non toxic and extremely beneficial. When the PH is below 4.5, it begins to cause the CL2 to separate from the liquid, and take its gaseous form, CL2, which can be dangerous. The lower the PH, the more CL2 is produced.

When making HOCl in a separate generator, you have the ability to test the PH and verify that it is HOCl and it is in a safe form.However, if you are using an all in one HOCl/Humidifier it makes it difficult to monitor what exactly is being produced.

It would seem that producing the HOCl in a generator, verifying the product it produces, than using it in a fogger, would provide the same benefits, without the risk

Below is a link to a very long and boring article. I read it so you don't have to, however I am linking it,  because it has a great chart/graph that shows how PH effects the solution, and causes it to change from CL2 to HOCl to OCl
