Why is it worth using original Ecosoft cartridges?

The Ecosoft brand (part of the BWT group) uses patented technologies in its cartridges that you won't find in cheap alternatives. By choosing the original, you benefit from:

  • PURE Balance Technology: If you have a filter from this series, only the original mineralizing cartridge will provide you with water enriched with calcium and magnesium in ideal proportions. This is the secret to the sweet, refreshing taste of Ecosoft water.
  • AquaGreen Membrane Protection: Ecosoft pre-filters are designed to perfectly protect the innovative, water-saving membrane. Using inferior substitutes can clog it.
  • 100% fit: You can be sure that the seals and dimensions are perfect, eliminating the risk of leaks.

Which set should I choose? Standard vs. PURE

Our offer includes sets tailored to your model:

  • 1-2-3 (Introductory) Kits: This is a pack of three filters (polypropylene + carbon) that we replace every 6 months. They fit most standard Ecosoft under-sink filters (Standard, Absolute, PURE).
  • Complete annual kits: The most convenient solution. They include pre-filters, a mineralizer, and a carbon post-filter.
  • Specialized cartridges: Single osmotic membranes, AquaCalcium cartridge and PURE Balance mineralizer.

Frequently asked questions

  • Yes.Most Ecosoft cartridges (especially the 1-2-3 sets) are made in the universal 10-inch standard. You can use them with filters from other manufacturers to improve filtration quality. The exception are "Box" systems (closed housings), which require dedicated Twist cartridges.


  • ContributionPURE BalanceThis unique technology, inspired by natural processes, not only adds minerals but also maintains a stable pH. Water treated with this cartridge has a richer composition (more calcium and magnesium) and a noticeably better, sweeter taste than water treated with a standard mineralizer.


  • The pre-filters are the same. However, if you want to achieve the PURE Balance effect in the Standard model, you'll need to replace the top mineralizer with the PURE model. This may require minor modifications to the connections (tubing) or mounting clips, as these cartridges may have slightly different designs.


  • Ecosoft offers standard and enhanced introductory kits. The enhanced kit includes a second foam filter instead oftwo carbon inserts(or Ecomix cartridge). This is recommended if your tap water is very heavily chlorinated or contains a lot of organic contaminants.


  • Of course. Every Ecosoft kit comes with instructions. Simply turn off the water supply, unscrew the shades with the wrench (which came with the filter), replace the cartridges, rinse the shades, and screw them back on. Remember to flush the system after replacement (drain 1-2 tanks of water).
