BWT water+more for coffee with greater precision
BWT water+more specializes in optimizing drinking water for professional use and has developed filter solutions for everything from kitchens and bakeries to hotels, restaurants and coffee environments. According to the manufacturer's own information, it is the world's leading manufacturer of water filters and filtration systems, with a clear focus on sensory quality: transforming untreated water into water with a consistent flavor, adapted to its intended use.
For coffee, it is precisely that combination that makes a difference. Good water should not only protect the equipment against limescale-related problems, but also provide a stable foundation for the flavor in the cup. BWT water+more develops technically advanced solutions to optimize water at the point of use, so that coffee, espresso and other hot drinks have better conditions for tasting as they should—day after day. That is why this series is particularly well suited to situations where you want to combine cup quality, operational reliability and more controlled water for coffee machines and espresso equipment.
How to find the right solution
The range is structured around different aspects of the same need. The cartridges themselves are the choice for anyone who wants to improve water quality for coffee while also reducing the strain on the machine. Within the cartridges, the most important differences are the series level and Size: Bestmax is the straightforward choice when you want proven multistage filtration, while Bestmax Premium is suitable if you also want the features that come with BWT Magnesium Technology. Size then determines the capacity and physical format that fit the installation.
The cartridges are also supported by products that make the system more complete in practice. An installation kit is useful when building or updating an installation, flow measurement helps you monitor consumption over time, and water analysis is a good starting point when you want to understand your source water before choosing a solution. Together, these products make the collection useful both for home baristas with established routines and for businesses that need more predictable operation.
Choose a cartridge by series and Size
These three options cover the most common choices in the series: the standard version or Bestmax Premium, plus M or V depending on your needs and installation.
Bestmax M
Standard series
For those who want a clear, proven choice for coffee, hot drinks, steam, or vending. It is suitable when the focus is on broad use and easy matching in an M size.
Bestmax Premium M
Premium in a more compact format
For those who want BWT Magnesium Technology for the Premium series' water optimization, but in a format that is easier to fit where space is more limited. A strong choice for coffee, espresso, tea, and vending.
Bestmax Premium V
Premium in a larger format
For those seeking the same Premium focus but in V size. Suitable when the installation is to be combined with a larger cartridge format for hot drinks and higher continuity requirements.

Build a more complete system
In addition to the cartridge, there are accessories that make the installation easier to monitor, adjust, and use in everyday life.
Bestmax Flex 1 mounting kit BWT
For a smooth basic installation
For those who want to get started with the right connections from the outset. The kit is suitable when you want to build a clean and practical filter installation around the besthead FLEX.
Aquameter with LCD display BWT
For monitoring consumption
For those who want to know how many liters have actually passed through the filter. Particularly useful when you want to plan filter changes more accurately instead of guessing.
Water quality meter BWT
For understanding the incoming water
For those who want to measure hardness, pH, and TDS before choosing or adjusting their solution. A smart tool when you want to control the taste in the cup more deliberately.

Bestmax Premium Flex 2 Mounting Kit BWT
This is the choice for those who need a solution that is more ready to connect to the water supply. Flexible connections, included adapters, and a flushing function at the filter head make it particularly practical when the installation needs to be adapted to the location rather than the other way around.

For larger formats in the same premium range
It is suitable when you already know you want Bestmax Premium and prefer a larger cartridge format. This makes it interesting for installations where you want to build on the same water profile but in a different Size class.
Frequently asked questions
Brief answers to the most important questions before you choose a cartridge, accessory, or take a measurement.
What is the most important difference between Bestmax and Bestmax Premium?
The clearest difference in this range is the series. Bestmax is the standard option for multistage filtration, while Bestmax Premium is the series for those who specifically want BWT Magnesium Technology. If you already know you want to choose from the Premium series, the main decision left is selecting the right Size for your installation.
How do I know whether to start with a cartridge or a measurement?
If you already have a functioning installation and want to replace or upgrade the filtration, you will usually start with the cartridge. If, on the other hand, you are unsure about your water quality from the outset, a water quality meter is a good first step, as it helps you understand hardness, pH, and TDS before you decide on a solution.
Do I need accessories in addition to the filter itself?
Not always, but the right accessories often make the solution better. A mounting kit simplifies the connection, especially if you are building a new installation or want a more thoughtfully designed setup. A flow meter is valuable when you want to monitor usage over time and replace the filter more systematically.
Are these products only suitable for espresso?
No. The range is clearly focused on coffee and other hot beverages, but several products are also relevant for tea, vending, and in some cases steam production. The important thing is to choose the cartridge and accessories based on how the water is used in your particular equipment.
