The 200ml Promolife Ozonide Oil Bubbler is specifically designed for use with ozone therapy.
 
This glass bubbler is great for breathing ozonides through oil.
 
The bubbler and straw are made of glass while the tubing is made of silicone. Many people use it to breath ozonides after ozone is bubbled through oil. This changes the chemical structure of ozone so it is breathable and non-irritating.
 
Simply fill the bubbler with the desired amount of oil, attach the tubing coming from your ozone generator to the straw that goes all the way into the oil, and attach your other tubing to the other straw.
