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

apparently kills more bugs than iodine or chlorine or silver

These arrived a couple of days earlier than expected, & I am happy to know that i have a way to make safe drinking water if the worst should happen. I read other comments saying they received tablets that did not have a long life date - but those I received don’t expire until October 2028 (just over 2 yrs from now). These chlorine dioxide tabs are a lot more expensive than other chemical water treatment alternatives, but I have read that these are way safer. Excellent, would recommend!

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.

I havn't used yet. There is alot of interesting research on the highly beneficial effects of Chlorine Dioxide for the treatment of C****** and I am sure it purifies water also.

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

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!

Right product, but just as well we were using asap as less than 5 months left before use-by date. The tabs should be good for up to 3 years, looks like this was old stock.

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.
