The Bolio No.2 Cone reusable hemp coffee filter makes a full-body pour over coffee mimicking the brew characteristics of a paper filter. We, like you are coffee dorks, seeking options, prioritizing flavor above all else. After trying all the other reusable cloth filters on the market we decided that the biggest issues were clogging, and flavor which was caused by the tiny fibers of cotton. We worked for months, testing and retesting all the various cloth types and thread-count and finally found the fiber type and thread count for making coffee. You should see our piles of samples. Hemp cloth is superior fiber for filtration for many reasons but the biggest are all due to fiber size. Hemp fibers are massive and don't ball up, get fuzzy and fall off like cotton. The big size reduces the amount of water and fines that are absorbed and trapped inside the fibers. Hemp more mimics fine steel wires catching the coffee grinds and passing the liquid through, which is exactly what you want. Cotton cotton fibers ball up, catch little bits of coffee and oil and then let go, requiring the cloth be scrubbed and destroyed to remove the fines. Easy to Use The Bolio hemp filters are easy to fill, lift out, clean, and dry for future use. Hemp Filters are reusable hundreds of times and are great for making smooth, natural tasting coffee. Hemp and paper are almost the same in their flow rate coefficient so it will feel the same as what you're used to using. Easy to Clean Besides rinsing your filter after use, we recommend cleaning your filter after about 20-30 uses or when the filter seems to develop a coffee aroma. This can be done by boiling your filter in water and white vinegar. This will remove some of the excess coffee oils buildup and will prolong the use of your filter. Made here in the USA…mostly. We sew most of our filters here in the rugged mountains of Colorado.
