These USA made glass-bonded silica air diffusers are a must have if you intend to drink ozonated water or make ozonated oils. Ozone will not break these air diffuses down over time nor will they add impurities into the water like the gray Chinese ozonator stones. The barbs are made out of Kevlar which is also ozone resistant.
