The 3 Stages of Complete Wine Filtration
The #1 pads are Coarse Pads. (5 - 7 microns) They remove large particulate in a heavy wine, typically those heavy reds.
The #2 Pads are Polishing Pads (1.5 - 2.5 microns) and they remove medium to small particulate and adds brilliance to your wine.
The #3 pads are Sterile Pads (1 - .5 microns) 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.
