Sterile filter pads for use with the Buon Vino Super Jet Filter. 3 per pack. These filter pads are the finest filter pads available for the Super Jet. They should be used when further clarity and brightness is needed than the #2 polishing filter pads can provide, usually for clear white wines. These pads are capable of removing up to 80% of the yeast in wine. Since they are such a fine pad, these should only be used on wines that have been filtered with #2 polishing filter pads at least once.
