Make sure you well ventilate the area before you return to it. Useful tool but kills everything alive in the area!

I'd be careful with this one. While it looks powerful (30,000 mg/h and covers up to 4,000 sq. ft.), the reviews seem a little sketchy—Fakespot gives it an F for review reliability. Also, ozone generators can be effective for odor removal, but they shouldn't be used in occupied spaces—they're not safe to breathe in. If you go for it, make sure to run it when no one (and no pets) are home, and let the air clear out before going back in. Might work well for cleaning out a basement or after tenants move out, but not ideal for everyday use.

Used an ozone generator to get rid of the cigarette smoke smell from a used car, worked great. I have also pumped it through my hvac system after we discovered some mold to kill any remaining spores.

My advice is to get a model with wifi connection. I've found that running it continuously for longer period leads to a stronger nasty "after smell". Instead I crack a window and use the app to turn on the generator after I left the room and run in cycles of 10-20min depending on room size. 10min on, 10min off, 10min on, etc. Usually 3 cycles. Then run inside, open all the windows fully, and then wait an hour to go back in. No nasty lingering smells doing it this way. If the original smell is still there I'll do another treatment cycle, but you really don't want to over do it with ozone.

Ozone can adversely affect indoor plants, and damage materials such as rubber, electrical wire coatings and fabrics and art work containing susceptible dyes and pigments[/B] (U.S. EPA).

so if you stick one in a room, or a car, you might regret it later.

Tempting, as I could use this to deodorize the car, trash cans, and the inside of the cabinet where I keep my cat's litter pan during my upcoming spring cleaning.

However, I've heard horror stories about ozone generators, including how they can melt plastic and rubber and are extremely toxic. Plus, the seller seems kind of iffy, so I'm not sure if it's a quality device I can trust.

I'll need to do some research or get additional feedback before deciding whether to buy it. Overall, though, it seems like a decent deal to someone who isn't very knowledgeable on the subject...

Like everything else, This is banned in California. I bought one a few months ago though off Amazon. Just keep searching and you'll eventually find a few that will ship. Not at $15 though lol

Unfortunately not. A friend tried getting rid of rodents, roaches and spiders in his basement using ozone and nothing happened. The spider on a web looked as if nothing has occurred. He even turned on a security camera to see if there was any disturbance during the treatment and he saw nothing. Even that spider didn't move. The pests still live there happily as if the treatment never happened.

Ozone isn't fatal for humans either, as long as there is regular oxygen in the room. At worst, it's an irritant at short exposures (I've experienced it). It's long exposures that's problematic because ozone is an oxidant, e.g. the extra O oxidizes atoms (by stealing electrons), including the atoms making up your tissues. Neutralizing oxidants is why we take antioxidants like vitamins A,C and E. I wouldn't worry about quickly running into an ozonated room.

Ozone is fatal for most pathogens because they have very few cells. Oxidation destroys those cells, thus destroying the pathogen. In contrast, an adult male has 30+ TRILLION cells. Killing a few of those surface cells won't kill the human.

Ozone was great during COVID. We disinfected exam/patient rooms and sterilized equipment, including masks and gowns, using ozone. UV was the other option but ozone had the advantage of going into cracks and crevices. The disadvantage, of course, was that we had to wait for the ozone to dissipate, e.g. return to O2.

I now use ozonated water to disinfect the home and even my produce. Studies show that freshly ozonated water is many times more powerful than bleach. Other studies show that ozonating produce can remove pesticides and make them last longer. The poultry industry uses ozonated water to clean raw poultry.

You can find ones that ship directly from China. They often ignore (or are ignorant of) the California ban. eBay is a good place to look.

Yes, because ozone oxidizes atoms, it can affect plastic, rubber, wood, etc. surfaces. The surface doesn't "melt," but it can age, yellow and weaken after repeated prolonged exposures -- not unlike prolonged UV exposure, e.g. leaving stuff out in the sun.

This was something to consider during COVID. Because there was a shortage of masks and gowns, we had to sanitize and reuse them. Since both ozone and UV can damage plastic, we had to assess whether they compromised the masks, which are made of a nonwoven plastic. It was ultimately decided that the masks were still effective after a single ozone or UV treatment. Obviously, you can't do this repeatedly, but it allowed us to reuse PPE at least once.

Damage to surfaces is generally insignificant (or even nonexistent) but it's something to consider. You don't want to run this with antiques or expensive paintings in the room. But periodic use of ozone won't damage most surfaces, e.g. an hour every few months. It's the repeated constant saturation of ozone at close range that's damaging.

If I need to sanitize something, I put the item and an ozone generator into a metal trash can. I then put on the lid and seal any gaps with duct tape. Do a 15-30 min treatment and then take the trash can outside where the lid is removed. I used to have a VERY weak palm-sized generator that could be used inside a sealed plastic bag. It was great for ozonating clothing, gym bags, insoles, etc.

My wife spilled milk in her car and didn't realize it until it was too late and one of these removed the smell permanently just running it for 30 minutes with all the doors closed.

Get an electric countdown timer. Set it for an hour to an hour and a half and get this started when you leave to go to work for the day. Crack a window in a faraway room that will let fresh air slowly come in during the day. All should be good wen you get home, as long as it's at least 8 hours later.

The Ozone molecules will attack anything like smoke in carpets or drapes, or anything alive, like bugs. (or you, if you foolishly stick around with it on) Ozone happens naturally from lightning.

Reading the product reviews, those buyers have no idea what they are breathing in. Ozone is a strong oxidizer and is known to damage your lungs when not using it appropriately, basically avoid breathing it in as much as you can. Obviously it's fine to smell in small doses but better to be careful. If you don't know what ozone smells like, it's basically that smell you might remember from a lightning rainstorm. The lightning creates ozone that settles near the ground, and that "fresh, zing" smell is ozone.
it smells clean /sterile !
