All Buon Vino wine filters have been designed to use GENUINE Buon Vino Filter Pads. Filter Pads are not all the same. They may be rated with specific micron sizes but they also must correspond to Flow Rate and Pressure applied to them by the pump. Buon Vino Filter Pads are a commercial grade quality filter and are specific to the Flow Rates and Pressures applied by the pump on the Buon Vino Filter Machines, providing you with the best filtration possible.
The #1 pads are Coarse Pads. They remove large particulate in a heavy wine, typically those heavy reds.
The #2 Pads are Polishing Pads and they remove medium to small particulate in your wine and add the shine to your wine.
The #3 pads are Sterile Pads – very tight pads that remove very small particulate in your wine.
We strongly recommend that you filter with the #2 pad first before filtering with the # 3 pads.
