AW: Grayl Wasserfilter?
See my post above:
Is this ionisation effect affected by sources of electromagnetic radiation eg. powerlines, telecom stations, radar stations and especially ESD (which often occurs due to the high-tech materials used in outdoor clothing)?
Is there any visible sign that the filter lifetime has ended? E.g. coloring of the filter if 150l are filtered or reduced flow speed?
What kind of antimicrobial agent is used in die Travel and World filter?
Is it some kind of prophylactic antibiotics adding to the increasing problem of antibiotic resistances?
