For cleaner, better-tasting water for your coffee. The BWT Bestmax Premium Water Filter cartridge that’s easy to assemble with its matching valve system. This innovative system gets rid of sand and rust in the water, softens it by removing hardening minerals, and then reinfuses it with Magnesium to improve the taste.

Cleans and softens

To make good coffee, you need clear, pleasant-tasting water. The BWT Bestmax Premium Water Filter cleans the water and gets rid of rust, sand, and other particles in the first stage of filtration. In the second stage, carbon filtration removes chlorine and other organic materials that may affect the water’s taste. And finally, the ion-exchange stage softens the water by eliminating minerals like calcium.

Magnesium infusion

What sets the BWT Bestmax Premium Water Filter apart is that it reintroduces magnesium into softened water. The balanced minerals in this filtered water give it a pleasant taste and ideal PH level that’s great for making coffee.

Better espressos

Water filtered by the BWT Bestmax Premium Water Filter has a balanced mineral content which makes it odourless but delicious to drink on its own. It also becomes the perfect solvent for coffee because of its ideal PH level. Filtered water from the BWT Bestmax can help you achieve crema-rich espressos.
