You can use a cloth, a filter etc. Allow the water to sit for a minimum of 30 minutes after adding the tablet(s). This is crucial for the tablet to effectively purify the water. After 30 minutes, the water should be safe to drink. Product Safety Warning Causes serious eye irritation. Contact with acids liberates toxic gas. May cause respiratory irritation. Use biocides safely. Always read the label and product information before use. Very toxic to aquatic life with long lasting effects. Very toxic to aquatic life. Warning! Do not use together with other products. May release dangerous gases (chlorine). Review: easy to use - Great item. Fast delivery. Thank you. Review: Long dated (11/2027 on mine). Conveniently in 20 sets of 10. 1 tablet per litre to be treated - UPDATE: I tested them. Just with regular tap water. While I was out walking. Put one in the bottle of water. They "fizz" slightly, like dissolvable pills do, but not so much. Waited 30+ minutes. (the water had got plenty of shaking as I was carrying the bottle in a bag). And tried it ... ... Yes - it DOES change the taste of the water. Perhaps it is a tad more bitter? But not that much more bitter. The main change seemed to me like the change in taste between soft and hard water, or between bottled and tap water. I do not find the change is taste to be "bad" at all - just different. And, as I wrote above, even if it was a bit iffy in taste (which to me it is not), it would STILL be FAR better than drink untreated trough/lake/canal/river/ditch water! I actually DOUBLED the suggested dose (so I put 1 tablet in 500 ml of water), so any taste changes would have been magnified, and like I said, the change is taste was obvious. (I am a big guy, so a bit extra every now and then is VERY unlikely to do me any harm.) As well as the taste, after waiting the recommended 30 minutes, I opened my water bottle and it did smell just a tiny bit vaguely like a swimming pool. That will be the chlorine, thought I. Not as strong a smell as a swimming pool, but a definite hint of it. Presumably, because I "double dosed" I got "double smell" as well as "double taste". To be honest, I found neither the taste or the smell in any way objectionable. But preferences and tastes differ. First Impressions: These are for my "oh, I am lost, and the sun is blazing, but there is an animal water trough / canal / ditch with water over there" hiking kit. In other words, for "found" water when I am on extended hikes or Ultra running. Taste? Who cares - gotta be better than "raw" ditch water ;-) Twenty strips of ten (2x5) - all dated November 2027 - so more than 4 years time. I will just take a strip of 10 with me - a strip of 10 are about the size of a banknote (with 10 little lumps in it), I suppose. So they will go in a pocket, or in the pocket on my "runner's belt" etc etc. Far better to also boil the water. BUT these tablets are far better than "raw" "found" water. Like I said, gotta be better than "raw" ditch water! As always though, boiling water thoroughly is the BEST method. About 5 minutes at the boil, and that is optimum. Filter it, treat it, AND boil it if you like. But boil it! [However, reality means one does not always have the time and/or equipment for boiling water with one, and one has to be careful of local regulations, starting forest fires, etc etc in dry weather. If "boiling" is not available, a pack of these water purification tablets are small and easy to carry, well-priced, and a good "second choice".] ## Features - Causes serious eye irritation. - Contact with acids liberates toxic gas. - May cause respiratory irritation. - Use biocides safely.
