Ozone and Pure Oxygen Diffusers-{Twin Pack}-Manufactured by Bubblemac Industries, Inc. Makers of The Forever Bubble Stone - 100% Glass-Bonded Silica Air Diffusers Model #1111FK-2

Very little ozone order compared to the blue ones that came with my ozone generator. At first, I thought the machine was failing so I took off the little white one & hooked up the original blue one and all the strong ozone order came back! Yay! Maybe I can use the little white ones for my hydroponic garden?!?

Perfect for making ozone water. Many people at my holistic dr office uses these as well. I will not use another brand for I feel this one is safe to use for drinking the ozone water.

These are great. Just what I was looking for to bubble with ozone 1/2 gallon & gallon jugs of water for purification & oxygenation purposes. One reviewer said there was residue in their water after using these. I have NOT experienced this at all. I've been using these a while & have had NO residue. I think they are EXCELLENT!

Bought these to replace the pet store "aquarium-grade" diffuser stones I had tried (ozone broke the plastic down, but the stone stayed intact).These bubblemac stones did the opposite (plastic stayed intact, but ozone broke down the stone...rapidly). Every use I would see white powder at the bottom of my glass of ozonated water. Don't need that entering my system.

Great glass bubblers. Use one for water and one for oil. Keep separate or the oil one will make the water taste yucky!!

These work perfectly with my ozone generator.

I find little pieces of the glass settling to the bottom of my jar breaking off from this so called ozone resistant bubbler very disappointed

I would order them again and again. Although I've had no need to. Great product.
