Bestmax Premium V

Water filter to keep your machine free from limescale deposits and to achieve the best possible taste.

BWT's Bestmax Premium filter cartridge is an all-in-one water purification solution. Excellent for filtering water for hot beverages like coffee, espresso is Bestmax Premium a modular multi-stage filter that uses the patented BWT Mg2 +-technology. This unique feature mineralizes the filtered water with magnesium, a known flavor enhancer that can be lost when using other filtration methods.

Bestmax Premium uses a five-layer filtration process as described below:

• Particle pre-filter - Separation of coarse particles such as sand and rust.
• Activated carbon pre-filter - Elimination of oxidants, protection of the ion exchanger against aging.
• High-performance ion exchanger - Removal of hardening substances, adjustment of mineral balance.
• Activated carbon layer - Elimination of organic substances, chlorine, foreign odors, and foreign tastes.
• Particle fine filter - Separation of fine particles and suspended matter.

The Bestmax Premium filter also reduces scale build-up inside espresso machines and coffee systems, dramatically reducing the need for descaling.
