All our products are eco-friendly, and made of entirely natural fibers.This Chemex style coffee filter can be used hundreds of times! Care instructions: Upon receiving the product, we recommend you boil it in water for 3-5 minutes to sanitize and preshrink. Just dampen the filter before each use for even flow, while allowing the coffee's natural oils through, creating a more delicious, smooth tasting coffee. After each use, dispose of the grounds, rinse the filter with warm water and allow it to air dry. For a deeper clean we recommend boiling the filter in water for a couple minutes to ensure it performs as good as new. Dimensions: 6”x 11”
