We're not just a leader in modern coffee filters. We invented them in 1908. Our paper production plant in Clearwater, Florida is state of the art. We produce filters to distribute throughout North America. Many advances in coffee filter technology have been pioneered by Melitta. Various innovations have been developed to fit the cone brewer throughout its evolution, including Flavor Pores, Double Crimp, material changes and oxygen cleansing. Our filters are designed to be durable, with the ability to extract coffee's full flavor. Made from the same high quality paper as our basket and cone filters, these filters help reduce the amount of oils and sediment that seep into your coffee. Less oil means better tasting smooth coffee. When placed in your percolator basket, these filters are designed to fold around your coffees grounds, encasing them in an easily removed bundle for easy clean up and disposal. Chlorine free. Poly bag wrapped package of 40 wrap filters. Fits all percolators.While we aim to supply accurate product information, it is sourced by manufacturers, suppliers and marketplace sellers, and has not been provided by Overstock.
