The Core

That's super interesting. My wife has had a lot of gum problems that have baffled dentists. They basically have said they just don't see people who take such good care of their teeth have such problems.

And you're doing this with the O3 Pure device?

Thanks. We already have the water flosser and Theresa's dentist suggested an H2O2 rinse. 

Interesting idea to use O3 instead.

Good find!  So I went digging...

1.5mg/l not strong enough to be classified as a disinfectant. Just a sanitizer.

I'll run these by the nursing home, for sure.  Thanks.

To wrap up my research on aqueous ozone, I found a tech article that said you need 500ppm to be a hospital grade disinfectant.

The technical definition of sanitizer vs disinfectant:   
Sanitizer - kill 99.9%  certain bacteria, in a specific period of time, and are regulated by the EPA.


Disinfectant -  kill 99.999% of a wider range of microorganisms; bacteria, viruses, mildews, or fungi, in a specific period of time, and are also regulated by the EPA.

Absolutely.  I have a campy-looking metal cabinet in the master bath for my daily medical equipment. That small vegetable washer O3 generator is located just above it on the corner of the vanity.  We've mentioned that O3 is heavier than air, so it cascades down to the top of the metal cabinet.  Over the past year, it has rusted a 6" x 6" spot where the O3 hits.

The large one I'm using says it is rated for 11,000mg/hr

About 2 weeks ago, I o3'd one of the double closets in the master bedroom. letting it run in a confined space with clothing & shoes for 1.5 hrs.  AFAIK, no negatives but it did take a day or more for the lingering o3 smell to go away.

My understanding is that it can break down other materials, and so make the room virtually uninhabitable.

>My understanding is that it can break down other materials

My nephew's wife had some badly burnt bones (making bone broth, didn't have enough water in the pot, left the house...) that made the house unlivable. They initially just wanted to bring in some ozone machines but after talking to a home restoration company they were advised against that since the ozone at the levels they would have needed would have greatly reduced the lifespan of all their clothes, carpets, sofas, etc.
