This is a promo life ozone generator medical grade with a lifetime warranty on. It comes with glassware, an air tank air control system\n And other accessories. I use this machine to breathe ozonites. When the COVID pandemic was going on and I never got sick or use it for ozone water, which really helps your gut, you can do your inflations with it. Which ozone will get in your brain? Rectal inflations with it to help your bowels. If you don't know much about ozone ozone kills parasites, mold fungus and viruses on contact. The\nOnly reason I am selling this one is because I'm going to upgrade to an ozone sauna.Never had a problem with it asking a $1000 for best offer text me with any questions. Thank you for looking
