Please note: This diffuser is not appropriate for use with inexpensive Chinese air-fed ozonators. The back pressure created by the small pore size of the diffuser cannot be overcome by the air pump inside inexpensive ozonators. These diffusers work extremely well with oxygen-fed systems and can be cleaned with heat or boiling in pure water.
