Thanks Jade — I hadn’t come across either of those bottles in the past, which is why they’re not included! 🙂 They both look pretty good, and at least claim to kill viruses as well as bacteria.

They suffer from the same problem as the Steripen and other UV-based approaches in that there’s no filter, so whatever taste, chemicals, and heavy metals are in the water will stay there and the sterilization only works on clean (ie, clear) water, but other than that they seem well-reviewed and have some nice extras like being able to sterilize other small objects (Crazy Cap) and being insulated to keep drinks hot/cold (both).

We may well include one or both of them in the next update!

It doesn’t, no, so I personally wouldn’t take it traveling with me.

Many people believe 0.1 microns can trim all chemicals. Unfortunately, the atomic level of the chemical chain is much smaller. Electrolysis & flocculation are required.

Measure PH, TDS at first, if PH is below 6, I would not consider

We are going on a cruise and the drinks package for water is high. What do you suggest as i am diabetic and 73 yrs old. JAR

When I’m going to places where I’m worried about finding enough water to purify, I take one of these sort of things along with me as a spare container. It folds down to virtually nothing in my bag, but I can purify an extra couple of litres in advance and carry it with me if I need to.

None so far. My one is stil going strong — my partner is actually taking it with her on a trip to India later this week.
