These are certified dioxin-free white filters, manufactured by Filtropa and there are 40 in a box. These fit our Thermos Filtercone Holder quite nicely. The box style on these changes, but what's inside remains the same.
These are my favorite cone-shape filters. They don't impart much paper taste, and are very sturdy. I think they are way superior to the flimsy Melitta filters that have busted at the seams while I have brewed my coffee on many occasions. The filter is bonded without the use of any glues or chemicals, and the paper stock is certified dioxin-free. Filtropa uses an oxygen-based whitening process which produces a totally chlorine free paper.
Each box contains 40 filters.
