Notes: For an FDA approved cartridge we recommend the new Pall PF10-.45 or PF20-.45, a polypropylene cartridge called Polyfine, to replace the Duofine in applications requiring FDA food contact approved products. We also recommend the new PIWC PP10-.45 or PP20-.45 which is a polypropylene cartridge, much like the PF10-.45, as a comparable alternative to this cartridge and is made with FDA compliant materials. None of these filters are recommended for final filtration prior to bottling.
