A reusable hemp filter adds flavor to coffee like a good cast iron pan does for food. I've been using a hemp filter for the past 5 years wherever I am. - Coffee consistency is smooth because of the finely sized filter - They're healthy if made with quality materials unlike disposable filters that may leak out microplastics - Ultralight travel friendly folding up easily - Reusable with good cleaning- You can find them in many shapes and sizes to customize for your preferred pour over method
