In paper, we offer V shaped, flat bottom "basket" type, and Melitta filters that are sort of a "hybrid of V "Flat V" hybrid. We have 6-8 cup flat-bottom filters that fit many standard automatic coffee makers (although some us the Melitta "Flat V" type), and flat-bottom Kalitta Wave filters. Then there are the pointed Chemex Filters, though in some cases you can use a Hario V60 in a Chemex. Their unique shapes make them fairly easy to match up to the appropriate brewer, and they work with a lot of brewers we don't sell too. We also have round disc shaped filters for the Aeropress. Most of our reusable cloth and stainless filters are specific to the Yama vacuum brewer, though we do sell a stainless mesh filter option for the Aeropress too! And of course we supply replacement filter screen for French Press brewers.
