Aquamira - Chlorine Dioxide Water Treatment Two Part Liquid (1 oz Droppers Bottles)

This water treatment tastes pretty good for a chlorine product. I usually add a sports drink mix or some other flavor powder *after* the water treatment process is complete and really don't notice the aquamira flavor. If the water is especially silty, I use alum from the grocery store to settle the sediments in the water before using aquamira. I've probably drank 20 gallons of desert stream water that used aquamira to make it safe and haven't had any health issues from the water.

Used this on my first week long backpacking trip. Filtered my water first and then used drops to be safe. Works well, never got sick and did not notice any taste.

As far as I'm concerned, these drops are a must-pack for basically any trip into the outdoors. They're easy to use, and they've allowed me to safely drink water from a bunch of different streams without any kind of sickness or any other issues. They're also lightweight, easy to pack, and last a long time, as purifying one liter of water requires just 8 drops from each bottle.There are a few downsides, though. First, you have to wait about a half-hour for the water to be safe. Second, some people complain that the drops make the water have a slight chemical taste.. Third, you do have to be careful to dry off the rim of your water bottle—if you scoop water you'll likely get water on the outside of your bottle's rim that will be sealed off from the rest of the water when the bottle's closed. That means that it won't be treated and could still contain bacteria or viruses.However, none of these are serious problems in my opinion. Waiting a brief time to drink after refilling your water isn't a big problem (especially if you've planned well), and it's not hard to remember to wipe off the rim of your water bottle. As far as the taste goes, I suppose it's personal, but I find that at worst it just tastes like drinking town water in many towns. The quality of the water you scooped up has more of an effect on its taste than these drops do, in my experience.In short, these are great option for any kind of wilderness adventure. They can make practically any water safe from pathogens, they're lightweight and easy to use, and while there are a few downsides I think they're outweighed by the convenience of the lightweight/easy-to-pack form factor and the safety factor (not all filters will filter out everything that these can kill).

I got these along with the Aquamira "straw" filters (Aquamira Frontier Emergency Water Filter System) for a trip to Mexico. Since I didn't get sick and the water tasted good using the two in combination, I was perfectly happy with these.The way these work is the following: (1) mix 7 drops from each of the two bottles in the provided cap. (2) wait 5 minutes for activation (the solution turns from clear to yellow). (3) add the solution to 1L (32 oz) of water and shake or stir. (4) wait 15 more minutes to purify the water. (5) at that point you can drink it with chemical taste, or use the filter straws to remove the taste plus anything else that might be in the water.What I did was to get one of the 1L Platypus water bag-type water bottles and try to keep it always full with water treated from these drops. I decanted that water into glasses or other water bottles to hold it after treatment, and then used the Aquamira straw filters on that water to taste clean and fresh. This way I always had water available, and did not have to wait after the initial start-up time for the first bag.I also used this water to sanitize hotel glasses (just fill them up with the treated water) and my toothbrushes (soak them in the treated water). So those are nice bonuses. I liked it enough to but extras for our home emergency kit as well.Why not 5 stars? Well, for one thing it's hard to say that I "love" water treatment! For another, they do take a bit of time and have chemical odor that really necessitates the separate filters. On the other hand, it seems to work well and I'll happily get more when needed.As for whether you need water treatment in Mexico, I've heard that it depends where you go. I was in Mexico City and the guidebook recommended it. I also noticed at the airport that the immigration officers' desks all had advertisements for Samsung water purifying containers. Given that the government itself seemed to be advertising the need, I guess it's a good idea. Have a good trip!

I have used these on many trips to developing countries where the water from the tap is less than clean and you can't trust the bottled water. (Not to mention the waste from plastic water bottles loitering the countryside and clogging landfills...).For example , the tap water in Leh, Ladakh was a greenish brown color for spring snow melt and rivers being very high (and probably yak and sheep feces from upstream, is my suspicion). I trust these drops enough that I filled my water bottle from that, waited 30 minutes, and drank it. Did that for 4 days before my trek departed, and 3 days after it returned. No problems.There are some not quite perfect bits, though. E.g.- it is a little hard to count the drops by headlamp in a tent with the wind howling and gent shaking to get exactly 8 drops from each bottle. Or sometimes I forget about the drops once mixed and leave the sitting for too long in the cap for an hour; since the instructions say to wait 5 minutes, I am not sure what happens if you wait too long. (The color starts to fade after about 20 minutes so not sure if the effectiveness does too.) If I mess up I just dump them out and mix a new batch, not a big deal.Overall I would say they are 100% effective and no bad taste. I don't mind the iodine taste from the tablets I used before discovering these, but these have advantages in effectiveness and less time before you can drink the water.

it works for me

Good value for the money!
