Product details

BWT bestmin is a unique filter system specially designed to miner­alize water that is virtu­ally free of salts. BWT bestmin is an inte­gral compo­nent of the compact BWT bestaqua MIN system's reverse osmosis unit, a clever combi­na­tion of reverse osmosis and down­stream reminer­al­i­za­tion, specially devel­oped for raw water with high salt and chlo­ride content.

This filter not only removes unde­sir­able compo­nents such as partic­u­lates and substances that lend an unpleasant taste or odour, such as chlo­rine, but also features a special miner­al­i­za­tion unit that refines low-mineral raw water to create a finely miner­alized gourmet drinking water ideal for making any hot bever­ages and coffee special­i­ties. Further­more, in regions where sourced water is predom­i­nantly soft water, BWT bestmin can also be used to reminer­alize raw water for general use in the restau­rant and catering industry.
