The BWT bestmin Premium is a single cartridge water filtration and mineralization system, perfect for home or commercial baristas with soft water. The bestmin removes particles, chlorine, and organic components; improves taste and smell; and adds minerals shown to enhance the desirable qualities of filter coffee. Notably, the AromaPlus formula includes magnesium to stabilize the water's pH and increase coffee's sweetness. This cartridge works well for espresso and filter coffee applications. The bestmin Premium must be used with the BWT Filter Head with Flush Valve. The filter head attaches to the top of the cartridge, allowing water to cycle through the cartridge and out into the water line. The flush valve enables you to easily replace cartridges and to purge the first few liters of water, a necessary step for purging air bubbles and excess resin that should be kept out of your coffee equipment. Before purchasing a cartridge, we recommend that you first purchase a BWT Carbonate Test to test the hardness of your water. The Carbotest will result in a GPG (grains per gallon) number that, when checked against this table, will help you choose the best cartridge for your water usage.
