Filter Cartridges

Filter Cartridges for 10 & 30 Inch Filter Housings and for Tenco Tandem Filter Housings

Final Filtration (or “Pre-Bottle Filtration”) is the final stage in the filtering process. This is almost always done using a cartridge filter housing—either for a single cartridge or multiple cartridges—or a series of cartridge filter housings. The purpose of this step isn’t to necessarily further the filtration, but to remove any sediment that may have been missed during depth filtration or developed afterwards. Accordingly, the porosity of the cartridges should be about the same as the porosity of the filters used during the final pass during depth filtration. Though cartridges have a significantly smaller surface area than other filter mediums, they are the only option for precise filtration—i.e. an “absolute” 0.45 µm cartridge filter has an exact porosity of 0.45 µm. Cartridge filter housings are also completely sealed off, ensuring that no outside elements can come in contact with the wine between filtration and bottling.
