The BWT bestmax Premium is a single cartridge water filtration system, perfect for home enthusiasts or commercial espresso applications. It is a quick and easy solution to reduce chlorine and sediment, improve taste and smell, prevent scale, and add advantageous minerals for coffee brewing. Notably, the AromaPlus formula includes magnesium, which helps stabilize the water's pH and increase coffee sweetness. By using this easy to install filtration system, you will see improved water quality, ideal for making coffee or espresso.

To use the BWT Cartridge, you will need the BWT Filter Head with Flush Valve. The filter head attaches to the top of the cartridge, allowing water to cycle through the cartridge. 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 before feeding the water into your equipment.

Before purchasing a cartridge, please refer to this table, as it will help you make a decision based on your water hardness.

This system only works in conjunction with the BWT Filter Head with Flush Valve. If you need one, be sure to add one on after clicking 'Add to cart.'
