+Due to the density of the cellulose sheets the material is not breathable. We succeeded in testing the feasibility of making it breathable. We pulverized it and compacted it into a breathable filter of 5mm thickness. The filter has three layers, the first and last of fabric to isolate fibers and possibly waterproof the pulp.
+The filter needs to be tested to evaluate its filtering capacity and porosity.
