My friend has been using one and they say it’s an “ozone cleaner” and that it disinfects whatever you spray the water on?
Is this bullshit?
Here is the explanation from the website: Ozone spray is the amazing, easy-to-use cleaner, sanitizer and disinfectant made from just tap water. This patented ozone spray machine takes ordinary water then electrifies it, creating aqueous ozone, an earth-friendly, totally safe and chemical free spray to clean and sanitize countertops, floors, windows, door handles and any hard surfaces in your home or business. The EnozoPRO (Hygeia) aqueous ozone sprayer is battery operated and kills 99.9% of bacteria and common viruses in only 30 seconds

In principle diamond catalysts with electrical current can create ozone in water. Looking at their instructions and being a chemist myself here are some thoughts.
1. Ozone’s half life in water is relatively short, maybe 4 minutes. This appears to use a battery that charges the water in the reservoir before you can use it. It is unclear how long that takes. Thus keep in mind ozone has a half life of about 4 minutes in water and also produces hydroxide radicals.. So if it requires long charge time ozone will be made and then degrade as more is made. Given the charge time isn’t mentioned it is hard to tell how much ozone will be in the bottle at use, there will be some probably. If charge is quick this may not be a problem where it is quickly made then used. I do NOT know if that is how it is done.
2. Diamond catalysts quickly develop scale (a chemical crust that quickly degrades catalyst performance. Which brings me to the instructions:
3. You discard this after 3 uses according to their instructions, likely I am guessing due to the scale buildup on the catalyst.
4. The cost. From what I can see online this costs $229 each. Is that worth it? Most definitely not. That is about $75 per use. There are far cheaper ways to safely disinfect things for much much less.
Is it a scam? In principle it could work assuming their claimed science is valid where they showed results of testing it. But that is not a scientific publication, it is just stuff on their website. They claim a proprietary diamond catalyst so I cannot comment on if it is one of the various doped diamonds that have been documented to work, or work well, or work at all. I am aware of diamond catalysts in scientific publications that show that certain types of doped diamond catalysts along with specific handling of the water through the catalyst to optimally work. If it works then it is not a scam.
Is it a foolish waste of money? If you have money to burn then no, if you don’t then yes. There are cheaper ways to do this that would cost a few dollars. Hydrogen peroxide in a spray bottle for example. Please note I am not familiar with possible damage to things like granite counter tops etc. with either approach so always test it before using it on various surfaces. I would imagine those bottles of with hydrogen peroxide cleaners probably warn about surfaces that might be damaged so read the bottle.
