FDA Approved 0.5 Micron Ozone Diffuser Stone
Ozonate water in less time with the 0.5 micron size diffuser pores than with the typical sizes of 15 microns or larger!
WARNING: After ozonating water, lift the stainless steel diffuser out of the water and continue bubbling Ozone gas through the diffuser. Blow out all the water and dry the stone. Otherwise minerals in the water will clog the small pores in the stone diffuser, and it will not work the next time you use it.
