A second crimp section increases the strength of each cone to keep it from bursting during use. These Melitta brown coffee filters are made using eco-friendly methods, and the manufacturer donates a portion of its proceeds to help ensure that American forests remain healthy and vital. Manufactured using an oxygen cleansing process, these cone coffee filters are free of chlorine and other chemicals, giving you a more natural and enjoyable cup of coffee to start your day off right.
