Can I reuse a filter?

We know it’s not always practical to finish a bottle of wine in one evening. We also know that filters are precious commodities! We have found that, when stored properly, a partially used filter can be re-used the next day on the same bottle of wine, with little loss of efficacy.  Rinsing and refrigerating the filter can help to maintain its reactivity, so please follow the steps below before attempting to reuse a filter.

Step 1 : Rinse the filter under cold water for at least 5 seconds 

Step 2 : Refrigerate the filter uncovered so the filter can dry


Step 3 : Reuse the filter to purify your remaining wine within 24 hours


For best results, we still recommend using a new Selective Sulfite Capture™ filter after three hours since its first use. This is because the surface of the filter is reactive and becomes “activated” when it gets wet with wine. During purification, the activated filter weakly interacts with the tannins in wine through a process called non-specific adsorption. Rinsing the filter helps to keep the filter active, for the same reason that washing a red wine stain before it dries keeps the stain from setting in.

Cheers!
