Filtropa filters, manufactured in The Netherlands, are of the highest quality. Filtropa manufactures them from specially compounded paper that is completely free of taste and smell and which has high strength when wet. They are then environmentally whitened without bleach.
Paper filters hold coffee grounds and allow water to steep through for a clean, clear beverage. The #4 size is by far the most common and fits most 8 -12 cup coffee makers that use cone shaped filters.
