Filter Types

There are several types of BWT filters available: Bestmax Premium S, Besttaste X, Bestsave M, and Bestsave S.


Bestmax Premium S

The Bestmax Premium is a modular multi-stage filter that uses patented BWT Mg2+ technology. This unique feature mineralizes the filtered water with magnesium, a known flavor enhancer that may be lost using other filtration methods. The Bestmax Premium Filter also reduces scale buildup within espresso machines and coffee systems, dramatically reducing the need for descaling. However, we still recommend semi-regular descaling to protect the longevity of your machine. The Bestmax Premium uses the five layer filtration process detailed 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 Nonwoven - Elimination of organic substances, chlorine, foreign odor and foreign taste.
  • Particle Fine Filter - Separation of fine particles and suspended matter.


Besttaste X

Designed to optimize water for use in coffee and espresso machines in areas of low carbonate hardness (soft water), the BWT Besttaste filter cartridges eliminate unpleasant odors and tastes from water reliably and effectively. The filter utilizes activated carbon to to reduce the level of heavy metals in the water and eliminates particles as small as 5 μm including chlorine, sand, and organic impurities. The activated carbon also features special silvering that helps to eliminate the growth of bacteria.

  • The Besttaste filter cartridges do not prevent scale buildup within espresso machines or coffee brewers. To ensure the longevity of your machine, we recommend regular descaling as part of your maintenance routine.

Anti-Scale Filters

Bestsave M

BWT's Bestsave water filter is an in tank filter that protects your machine against scale buildup and helps to improve the taste your espresso. Wrapped in a food-grade quality fleece, the Bestsave uses an ion exchanger to bind calcium ions in the water. This process also helps to remove unwanted tastes and smells by significantly removing heavy metals like copper and zinc and chemicals like chlorine from your water.

  • To activate the Bestsave filter, simply leave it in a full tank of water for 8-10 hours. Once the filter is activated it will work to filter your water until it expires. In the interest of hygiene, BWT recommends changing out the filter every two months.

Wrapped in a food-grade quality fleece, the Bestsave uses an ion exchanger to bind calcium ions in the water. This process also helps to remove unwanted tastes and smells by significantly removing heavy metals like copper and zinc and chemicals like chlorine from your water.
