BWT Bestmax Filters
The BWT Bestmax, with its simple and practical usability, is going to be a great choice for an all-round filter cartridge. This universal, ion-exchange filter system helps to optimize your raw water to your specific requirements while protecting your equipment from limescale buildup. A blended partial flow (0–3) is adjusted at the filter head depending on the water hardness and requirements. Check valves in the filter head prevent any water from back flow into the drinking water mains or filter cartridge and protect against uncontrolled water discharge. BWT bestmax food-safe filter systems are pressure-resistant and safe.
BWT Bestmax Premium Filters
The Bestmax Premium filter cartridge by BWT is an all-in-one water filtration solution. It is particularly ideal for filtering water used in hot beverages such as coffee and espresso. The Bestmax Premium is a modular multi-stage filter that incorporates BWT’s patented Mg2+ technology. This innovative technology enriches the filtered water with magnesium, a well-known flavor enhancer for your coffee that may be lost to other filtration methods.
BWT Best protect Filters
The BWT Best protect filter solution is designed to significantly prolong the lifespan of your machine while enhancing the quality of your espresso. Using BWT’s advanced 5-stage filtration system, it effectively prevents the accumulation of unwanted minerals such as limescale and gypsum. Additionally, it maintains a consistently high pH level, reducing the risk of corrosion and safeguarding your machine from the buildup of excessive deposits. The activated charcoal fleece used in Best protect ensures that you enjoy crystal-clear water, which is essential for producing high-quality beverages.
Water is, undoubtedly, an often overlooked variable in the coffee-brewing process that impacts the final taste to an almost unbelievable degree, and it’s in this world that BWT water filters emerge as champions in the pursuit of excellence. By combining advanced technology, a commitment to taste, and a focus on sustainability, BWT has elevated the standard for water filtration.
If you have any questions about BWT water filters or water filtration in general, please contact us. We are always happy to talk all things coffee and espresso, and we would be thrilled to help you find the right water filtration system for you.
Water Treatment Requirements Overview pH: 7-9 Total Hardness: 2-6 grains TDS: 50-200 mg/L Alkalinity: 40-100 mg/L Chloride: <30 ppm Silica: <10 ppm Chloramine: <.1 ppm Chlorine: <.1 ppm Improper water treatment is the most frequent cause of espresso machine damage. Water is complex and varies significantly between regions, so take great care to test the water quality at your location and adjust as necessary. Employ the help of a reliable company (Slayer recommends OptiPure and BWT) to evaluate your water and recommend and administer treatments. When evaluating water quality, the two most important factors to consider are calcium carbonate and chloride: Calcium Carbonate: dissolved mineral that determines the "hardness" or "softness" of water. The desirable range of hardness is 2-6 grains. Over time, calcium carbonate accumulates as a hard substance, called “scale”, and will inhibit the flow of water. Machines subjected to “harder” water (greater than 6 grains) will accumulate scale faster and require maintenance sooner. Chloride: chlorine combined with an electron from a negatively charged ion. Chlorides produce salts that impart a strong taste, which alters the flavor of the espresso. Chlorides also encourage pitting corrosion, which causes damage to the machine. Incoming water should have no more than 30ppm chloride content. Your water filtration company will create a treatment plan based on your water needs. Choose a filtration company that has solutions for addressing issues related to both calcium carbonate and chloride. Common treatment options include Carbon Filtration: a process by which water passes through the granular activated carbon, which attracts and retains many chemicals in the water that have an unpleasant color, taste or odor. Carbon filtration is necessary for all machines. For water with 3-5 grains of hardness, carbon filtration is likely the only necessary water treatment. Ion Exchange: a process by which water passes through an ion exchange system, where undesirable mineral components are retained and more desirable substances such as sodium are released. An ion exchange system should be used in combination with a carbon filtration system and is especially beneficial for water in the range of 6-9 grains of hardness. This system is relatively inexpensive and effective in removing inorganic substances. It does not, however, remove organic substances, such as bacteria. Reverse Osmosis with a Blend-Back Valve (or Remineralized RO): a process by which water is forced through a semipermeable membrane with selective pore sizes at high pressure, then blended with the appropriate amount of desired minerals. Reverse osmosis may be a good solution for water in the range of 6-9 grains of hardness and is mandatory for water above 9 grains. When blending minerals with the filtered water, target a TDS (total dissolved solids) value of 75-125 ppm. Experiment with various TDS levels to determine what produces your preferred taste. All Slayer espresso machines need to be connected to a carbon water filter to remove chlorine, sediments, odor, and undesirable tastes. This requirement is in addition to any other necessary water filtration systems. Filtration requirements may vary seasonally. Water should be tested during each season to determine the best filtration plan. Once a filtration method has been selected, take note of the filter’s peak capabilities. Replacement of filtration is based on volume and varying levels of hardness. Contact the filtration provider or vendor to inquire about the life expectancy of the filters, then schedule replacement and installation accordingly. ***IMPORTANT: Damage to or failure of your machine due to inadequately treated water is not covered under warranty. Every time a new water filter is installed, thoroughly rinse the filter before attaching it to your machine or pump. Run water from the supply line through the filter and down a drain for at least 2 minutes, fully washing the filter and the residue or loose fibers in the filter cartridge. Skipping this step will cause damage to your machine.
