reliable standard

Good to have in case of an emergency. These work well (I know from experience) and are easy to use. Compared to a mechanical filter (my preferred purification method) these take up next to no space and no maintenance is needed. Yes, there's a bit of an aftertaste from the chlorine but it's better than catching giardia! The package I received was marked with an expiration date of 5/2021.
