Description
The BWT AQA drink ZINC + MP400 Starter Set is the “big brother” of the MP300 and is based on exactly the same filter technology. The main difference lies in the significantly greater filter capacity and the cartridge’s physical dimensions.
It is particularly suitable for households or small offices with higher water consumption.
Key features & benefits
Like the MP300 model, this cartridge offers multi-stage filtration:
Mineralization (zinc + magnesium): During the filtration process, the tap water is enriched with the valuable minerals magnesium (up to 35 mg/l) and zinc (up to 3 mg/l). This supports the immune system and improves the taste of hot and cold drinks.
Limescale protection: Water hardness is reduced, reliably protecting your coffee machine, kettle or hot water dispenser from limescale buildup.
Reduction of contaminants & odors: Substances that affect odor and taste (such as chlorine), as well as any heavy metals (e.g. lead, copper), are filtered out.
The difference: Technical specifications
This is where the MP400 model stands out:
Feature Details
Filter capacity Approx. 2,100 liters (at 12 °dH) – for comparison: the MP300 handles approx. 1,400 liters
Dimensions Height approx. 500 mm (including filter head), diameter 130 mm
Service life Max. 6 months per cartridge (depending on water hardness and flow rate)
Installation Vertical or horizontal under the sink (cold water connection)
What’s included in a starter set
If you purchase the system as a complete “starter set” (and not just as a replacement cartridge), it generally includes everything you need for the initial installation:
BWT filter head (with integrated backflow preventer and mounting bracket)
Filter cartridge (ZINC + MP400)
1 1200 mm braided hose with 2 x 3/8-inch female connectors and 1 T-piece for connection to the angle valve
Tip: Since the MP400 cartridge is relatively large at 50 cm tall, including the head, be sure to measure the space in your under-sink cabinet before purchasing. If there’s enough room, its higher capacity often makes it the more economical choice in the long run.
