My buy recommendation is founded with the good value for money (compared to the BRITA Maxtra filter): I use the filter in the BRITA Maxtra system and contrary to the review of other customers fit these cartridges perfectly, whereby the water is not at the edge of "passes" (clearly visible). They allegedly do more than other filters, but I change eh every four weeks for reasons of hygiene. The filters are new and still preserved until 2017. A difference in taste I can not tell yet. So four star and a strong buy recommendation. Five Stars get the product until I present similar analysis values for drinking water from the laboratory)
