Ozone Generator for Hot Tubs and Cold Plunge, 100 mg/h, Upgraded SPA-124 Spa Ozonator Kit for Swim Spas, Portable Mini Ozone Machine with Check Valve and Tubes, 110-120V AC(NEMA 1-15 Plug)

Works just fine, have it connected to my Master Spa Clarity hot tub at 240v.

I bought this to help keep the water in my cold plunge cleaner. I feel like it's doing a good job as long as I keep the water at relatively low temperature(below 60 degrees Fahrenheit). I also noticed that the tube went white after a week or two but read that this is normal. So far it's doing what I bought it for.

This is a great unit. I easily installed it. Replacing a much more expensive, but outdated ozoneator. The tub was previously plumed for ozone, so it’s easy to see the unit working from the equipment space and the bubbles coming up from the bottom. Stand by for long term use report.

Product did not do anything. No ozone smell or water quality improvement. Waited to late to return.

Works great even though It says for 110v and I hooked to 220v. It still works great.

Clean water

I ordered this little ozone generator to use with a 60" long inflatable cold plunge pool that I use more for a hot tub than a cold plunge. It's great while camping in my RV for a couple weeks in a national forest or something as I can just fill it once and keep it fresh and sanitary with the ozone generator. The cold plunge tub has a quick connect water inlet and outlet so the water can be recirculated with a 12v pump which sends it through an on-demand propane water heater. I just put this ozone generator inline right before the water inlet on the tub. This injects ozone into the water just before entering the tub and the regular flow keeps more ozone coming in as the water recirculates. It's so much easier to just use this simple device vs messing with chemicals that are then in the water to get absorbed through the skin. The ozone also destroys all the stuff like soap, lotion, urine, etc. that might get into the water. It makes me feel much better about enjoying the water when I know it's been all sanitized by a gas that I'm not going to absorb through my skin like chlorine. Overall this is a simple and reasonably priced unit that's easy to set up and use.

I got this a while ago for our cold tub. It took a bit to figure out how it worked and to test it out, but now that it’s up and running, it seems to work well! It is pretty small but it still puts out a lot of ozone and keeps the water fresh for longer. Happy we got it!!
