Revision history [back]

Glad to hear that my response at least had comedy value...
I contacted Vestergaard to ask them when the Lifestraw Family 2.0 (https://www.vestergaard.com/lifestraw-family-2-0) will be generally available but am still awaiting their response. DelAgua Health had been trialling it in Rwanda (https://www.delaguahealth.com/programme/rwanda/). I understand it is supposed to improve usability and imagine Vestergaard would be very interested to hear your feedback.
Also, if you haven't seen it already, a recent discussion on household chlorination is available here: https://archive.knowledgepoint.org/questions/1019/chlorination-of-surface-water/
Kind regards
Martin
