What are the filter materials in the SweetWater Microfilter?
The labyrinth depth filter is made of a proprietary blend of microscopic borosilicate fibers in a specially formulated binder resin. A black (or white) mesh filter-replacement safety indicator is imbedded in the filter to let the user know when to purchase a new cartridge. Lastly, there is granular activated carbon to reduce unpleasant tastes and odors.
