The Peugeot Flat Filters are your secret weapon whenever you decide to open that vintage red wine. Simply fit the filter into the Peugeot Sphere or Victorean Decanting Funnel and eliminate any trace of sediment. This filters any mature wine without ruining the quality. This set of two flat replacement filters is an absolute must to go along with the Peugeot Funnel. Enjoy every sip to the wine's fullest potential.
