After opening the bag (carefully with a scalpel) can preview an olfactory nothing remarkable to be found, the smell is neutral. After commissioning of the cartridge and rinse several times, could zzt. no abnormalities such as a change in pH or in a negative Enthärtungsverhalten be found. As far as the filter cartridge seem to be OK.
I herewith request the supplier as distributor of the product, with respect to (moisture in the primary packaging) to contact, if necessary, it is "only" a slight problem in the packaging process (rel.LF). We have zzt. 2 pcs. Of F-cartridges-returned, and are in suspicion this original packaging (as delivered) a ext. certified testing laboratory (wrt. Mirko Biology / heavy metals / Chemical residuals) passed.
I ask the part of suppliers to clarify also in view of the fact (product liability), that this is a product in direct contact with food (water) and in accordance with possible far-reaching consequences.
If the record straight, I will gladly give a positive rating.
