The Membrane diffuser is manufactured using EPDM rubber, with rows of perpendicular perforations that are ideal for pond aeration. These diffusers are easy to clean. They do produce a slightly larger bubble than the air stones. The major advantages of this diffuser are its trouble free operation with low maintenance and ease of installation.
