A replacement ceramic membrane for the IO diffusers, Acrylic Series and Stainless Steel Series alike — to renew an old membrane, or as a spare for maintenance time.
Replacing the ring keeps an IO diffuser at its best for years. The membrane is made with the same nano CO2 mist technology as the diffuser: the gas passing through the porous ring dissolves into the water as tiny bubbles.
Choose the size of your IO diffuser: small or large.
Shipping and delivery
Free delivery on orders over €200; otherwise €9.99 in Europe and €14.99 for the rest of the world. Orders placed before 2 PM CET are usually processed the same day — a regulator may need a little longer, because every one is assembled and tested before it ships. Delivery is fully tracked with FedEx: 1–2 business days in Europe, 3–5 worldwide. Customs or import duties outside the EU are charged on arrival. Shipping policy · Returns
