Brew up some clean, fresh tasting coffee in the comfort of home. These high quality GEESTA charcoal replacement filters are better than the originals and will save you money in the long run by eliminating the need for bottled water. They reduce chlorine taste and odor, while removing select pesticides, chemicals, bacteriostatic, lead-mercury, copper and cadmium for cleaner, great-tasting waste from your brewing water. The result is healthier and better tasting coffee, tea, cocoa and other beverages! We recommend replacing your filer every 2 months or every 60 water tank refills, so this pack will last you a good six months. Filters are individually packaged and sealed for quality and storage, so there__s no reason not to stock up for perfectly delicious cups every time.
