The Ultro Fibron + Scale is a new water filter from the team at BWT. It is designed to help remove Sediment with a 5 micron carbon block. It will also help improve the taste and aroma of your espresso by removing substrates like Chlorine from the water. The Fibron + Scale filter also helps to soften the water to reduce limescale build up in your coffee machine. It is perfect for espresso machines where the water quality is good as a simple sediment filter or to be used with as a pre-filter to a BWT Premium.
