This is a special gasket to adapt Jupiter filters to use in Nexus or Smart water ionizers.
Jupiter and Nexus filters look the same in the pictures. But beware, Jupiter filters don't fit Nexus and Smart water ionizers and vice versa. This is because the bottom filter opening of the Jupiter filter is too large to fit the Nexus or Smart machine.
Directions: Insert this gasket in the hole at the bottom of the Jupiter filter to convert it for use in a Nexus or Smart water ionizer.
Gasket is reusable.
