Untreated water can wreak havoc on your espresso machine over time. While regular cleaning and maintenance are necessary for increasing the longevity of your equipment, prevention is also key.

BWT BestProtect Water Filters minimise the risk of corrosion and limescale and gypsum buildup in your coffee machine by removing particles from and balancing water pH levels. Not only does it protect your machine, but these filters also make sure you have clean-tasting water to brew with.

Minimises corrosion

Corrosion is a naturally occurring process and its causes are countless. However, there are certain factors that can accelerate it including certain chemicals, minerals, and even bacteria. While nothing beats regular maintenance for keeping your machine in top shape, filtering your water with BWT water filters can nip the problem in the bud.

Through filtration and ion exchange, BWT BestProtect clears your water of nasty particles and chemicals that could induce corrosion and balances its minerals and pH level to further protect your equipment.
