LifesystemsChlorine Dioxide Water Purification Tablets for Travelers Camping Backpackers - Treats 30 Litres Of Water

The taste reminds me of the tap water in a place I used to live - very chlorine-like but bearable. I haven't tried them in badly contaminated water (as far as I know) but didn't get poisoned in two days and about 7 litres.Tablets are individually wrapped in foil within the box, which is handy when using them in monsoon season or Scotland. A couple of months after first use I found that the paint on the foil packets had flaked in a few places, and it felt like one of the tablets had disintegrated. The most likely explanation is that a few drops of water got in and gradually ate through the packet, which surprised me but I had been on a moor so there's a fair chance the water was acidic.

These tiny tablets are part of my everyday kit when I'm camping or trekking. I'm currently training to climb Aconcagua, the highest mountain outside the Himilayas (see my profile for more info on the expedition) and these tablets mean I'll always have safe water to drink.They only take minutes to make a litre safe. I fill my platypus or Osprey hydration pack with 3 litres and so use 3 tablets.My advice is leave a strip in your first aid kit, a strip in your most used rucksack and a strip in your waterproof pocket.When you're hiking with a 20-30kg pack up hills, particularly in heat, you'll need to drink at least 0.5 litre every hour - I typically drink nearer double this. If you don't want to carry 4-5 litres (ie 4-5kg) of weight from the start, these little tablets will make sure you can top up from streams as you go!Happy trekking!

Does the thing it should, doesn't taste much, doesn't taste at all if you run it through a lifestraw with a carbon filter... Also props to the seller, my order went walkies with royal mail and they sent out a replacement without a fuss. Thanks!

Chlorine dioxide is simply the best way to chemically purify water quickly. 1 tablet does 1 litre of water unless there are lots of 'bits' in it or its very cold - in which case you will need 2. Using 1 tablet the water is ready in 10 minutes, using 2 tablets that extends to 30 minutes.30 tablets in a pack so that's 15-30 litres of water per pack. Standard chlorine tablets are cheaper (normally around 70 - 90 tablets for a similar price) but leave an after taste and are not as effective killing certain bugs. These are not the cheapest but do the job well.Come in a nice hard plastic case for protection as the tablets are in silver foil wrap.

They are ok I guess, only problem is one will get an after taste in the mouth after using these tablets.

1/5 is based on the fact that *HALF* the pills I got, emphasis on HALF, were all mushy pasty messes. This means that air/etc have gotten to the pills during storage and caused them to disintegrate as they absorbed the moisture.This is half out of the entire pack (took all the pills out and checked manually). See photo for one example where from six tabs, five deformed under gentle pressure. One wasn't that far gone, but the other four are total paste messes that will not be usable. It's worth noting that out of five sets of six tabs, only one of the sets had all the pills usable. All other four (including this one) had at least three tabs that failed to hold their shape under gentle pressure. Anyway, trash can for you, the remaining good ones will at least see some use. The expiry of 2023 indicates that the pills should have all held up until then, which raises questions as to their packing. Maybe not in a dry environment? I don't know.Now on to the good part. They do work. Emphasis on work. Chlorine Dioxide pills are more effective and provide a stronger oxidizing agent than conventional chlorine pills, and given their manufacturing cost are appropriately priced higher. They won't win any awards for aroma or taste (by god you'll drink more than your fair share, the aroma is like pool water on steroids, especially if you use two pills for some sketchy water) but that's what you get for a biocide designed for use in the fetid pools of South Africa.If half the pills weren't already paste before I got to them, I'd get more.

Does what it says on the tin! Quite pricey though!

Bought as a safety measure just in case when going to Asia. Wanted something that would not taste too terrible. Happy to say that I tried this out on water from my water butt, using a steel 1 ltr bottle and as instructed one tablet. Left for 20 mins although it states 10 on the instructions. I have not had any ill effects and the after taste is acceptable.The packets of tablets are in sealed foil and all contained in a hard plastic case.
