Fit the filter pads according to the Vinbrite Filter instruction. Prime Pads are a coarse grade pretreatment pad and are part of a system of pads that are available for the Vinbrite Filter. They will enhance the overall performance of your Filter by removing larger solids and colloidal particles that may block finer filter pads. You may not notice significant differences in the clarity of your wine after passing through the Prime Pad, but the subsequent flow rate and performance of Filtabrite or Crystalbrite Pads will be improved. Prime Pads can also be used to filter a spirit wash prior to distillation. This will ensure a cleaner wash and reduce flavours carried over from the distillation process.
