These things are snake oil, they don’t do anything, just use soap and water and you’ll be fine. Anything you see claiming to ionize, ozonize, or “structure” water, like that kangen crap, is just using words to sound scientific to pass off their gimmick.

The way they work is they trick you into spending 53 bucks for pure nonsense.

(And if it actually does create ozone, pure nonsense that will damage your lungs.)

You will be ingesting pesticides your entire life as has man since the dawn of time. Your first logical breakdown is assuming that pesticide ingestion is bad. You eat apples right? They contain arsenic. Are you going to ozone them to remove the arsenic? No? Why not...its legit poison! You have to realize that the dose is the poison and you consuming on a daily basis, an infinitesimal amount of dirt, pesticides, rodent feces, hair and all manner of unsightly items cause no harm.

Next item up for bid is the massive influx of Tiktok and other videos that show these items "removing pesticides" via ghetto ultrasonic cleaning, ozone generation, both or other quackery. What about herbicides though? Fungicides? Insecticides? Fertilizers? We not caring about other chemicals in the farming process? Will these cleaners remove surface contaminants? Yes. Can you do the same thing for $0 with a rag and a 15 minute water bath? Yes. The results will be the same within one standard deviation.

Now if you want to get one of these just to make your feel better even though its an ignorant purchase, great....go on with your bad self. There's no harm in ignorant purchases, heck some love getting nitrogen fills in their tires. But do so with open eyes. And zero of these products have any run-time worth a damn for us to discuss in this subreddit.

I’ve used ozone generators at the industrial scale, I might be able to be explain some of the science behind this. -“Does the water get “ozonized”? Yes. Ozone is just three oxygen atoms stuck together instead of the usual two. Just like oxygen (O2) gets dissolved in water, so does ozone (O3). If your unit is working (you’ll know by the strange sharp smell in the air) and it’s running through water, some of that ozone is dissolved into the water. however, how much will depend on things like depth, ppm concentration at the emitter, temperatures, ect, which leads me to:
—“Can I put the next batch into the same water?” It depends on how much dissolved O3 is in your water. These small units are renowned for being woefully under producing or (much rarer and scarier) wildly overproducing. Without equipment and testing it’s likely impossible to judge if it’s still at an effective ppm. Lastly: “why can’t I find solid information on how this works against pesticides”
There’s probably just too many variables. We know it’s effective against bacteria and yeasts, most biological microorganisms you just can kill. However, pesticides are such a large and diverse group of compounds that it becomes a matter of “which one, how much, under what conditions, and what are you left with?” For instance this paper has in its forward this statement “The dose of O3 was the most influential factor and had to be properly optimized. “ and that’s in wastewater. The advertising its effectiveness is likely banking on the thinking “PROBABLY a strong oxidizer (like O3), at MAYBE this concentration, POSSIBLY denatures SOME of these pesticides… Probably”. Honestly even if it was effective I’d be worried about consuming whatever oxidation does to these pesticides, who knows what fun carcinogenic tar that makes. Ozone is neat for a lot of reasons, and does a pretty good job of sterilizing and removing smells. On the other hand it is a hard to control lung irritant. When O3 is used at scale, it’s largely because using a more conventional chemical (like chlorine bleach) is a no-go, I’d push for alternatives at home.
Tl;dr.
It’s not ALL snake oil, but at best isn’t as effective as washing with soap and water, at worst it’s damaging your lungs and making weird free radicals with pesticides.

Baking soda, vinegar,, & distilled/purified water works great.

tests showed that that's not enuf to clean pesticides and using vinegar also changes the taste of the vegetables so.. no go

damn... why'd you have to mention nitrogen in tires bro... that hit me hard. LOL

thank you so much for sharing your wisdom on the matter. Your explanation helped me a lot. I appreciate it.

Very interesting. Thank you.

These don’t work. I work in food manufacturing and we paid about 50k for a commercial ozone machine to replace sanitizer and reduce labor. After environmental testing, I am fairly certain it does nothing. Science (and a good sales pitch) is there but facts to back it up, is not.

Watch out. While ozone is a tremendously effective sanitizer, it does to by hyperoxygenating everything around it. So in the case of food I would be concerned you are creating excessive oxidants for your digestive system.

You would be better off peroxiding your carrots. Its an effective but gentler oxydizer.

Yeah even if the ozone machine gets surface level contaminants out, that says nothing about chemicals that penetrate into the fruit itself.

Cherries for example, are often sprayed with a hardening agent prior to being picked. This is to make it so the skin can stand up to the rigours of being picked, sorted, packed and shipped with minimal casualties. This chemical penetrates through the thin af skin of the fruit and can never be removed. As a picker they make you wear N95s (on good orchards, bad ones don’t mention it at all) because if you get someone pregnant after inhaling a bunch of this chemical in the trees, the children are at greater risk of birth defects. But as far as eating this chemical goes, if you eat too much in one sitting you get the runs like any low fibre fruit but otherwise it’s totally safe.

Edit: fixing bad autocorrect

There was a recall on Philips CPAP machines if the user had utilized one of those cleaners like the "So Clean" units. The CPAP cleaners use ozone generators to "clean and sanitize" the mask and tubes, but Philips found that these machines were degrading and damaging the mask and tubes and causing all kinds of nasty chemical reactions that are dangerous to humans. Seems to me that you wouldn't want to use something like that (ozone generator) on anything you even come in contact with, let alone consume.
