how long does it take for a liter of water to be purified with these tablets?

For all concerns 4 hours. Katadyn's Micropur tablets claim to be "effective against killing viruses and bacteria, including cryptosporidium and giardia." Most concerns are eliminated within the first hour. But cryptosporidium takes 4 hours . I am planning to use the tablets in conjunction with a water filter. My water filter removes cryptosporium - so I won't have as long to wait...But always better to be safe than sorry.

So that I could get a correct answer for you, I had my husband suck on one lozenge and it took 10 mins to dissolve. He did not chew on it during this time. I hope this is helpful to you. I would have done it myself, but I bought these for my husband.

Unopened bottles of Potable Aqua tablets, when maintained under controlled temperatures between 60 and 86 °F (15 to 30 °C), should remain effective up to four years. Exposure to heat, humidity, moisture, and air will reduce the effectiveness of the tablets. We recommend that an opened bottle not be kept for more than one year. Keep the cap tightly sealed.Although this product is not required to have an expiration date (taken from their website. glad you asked looks like i need to buy new ones.)

3-4 chlorine tablets. I let them dissolve completely before adding new tabs. You can adjust how many tablets you put in based on your chlorine levels. If it's too high take out a tab or 2... Be careful not to let your chlorine levels get too low allowing algae to grow. The tabs will last roughly a week.

The filters last more long than, but i personally change it every time I notice the water pressure of the filtered water decreases which usually happens after 5-6 months but it also depends on how much water you drink a day

Liquid oxygen improves oxygen level in the blood. I have heard of tablets used for emergency water purification but have no experience with their use.Marge

There are 2 bags but the gray bag only holds the unfiltered water. You put your unfiltered water into the gray bag and it drains by gravity into the blue bag. It takes about 20-40 minutes and you get ~4 liters of filtered water. You never drink from the gray side! I just spent 3 weeks in the Himalayas and we took 2 of these and used them every day.

There is a knob for purified water and normal water(its on the right side of unit. You can see it in the picture.). Normal water flow is same as your tap flow but flow for purified water is less. It takes almost 20 secs to fill 1 lt bottle. But for me its not too slow.

Maybe 15-20 minutes but everyone is different. BTW, I cut each tablet into 3 parts and that works just fine for me. I use it to drink warm lemon/water in the mornings.

First of all the cleaner the filter, the faster it filters. When it is new, it will filter the full amount in about 6 hours. After the filter gets some use, it will take a bit longer. I take mine out and wash them every 3-4 months and change them once a year.

I believe at least half an hour or more. Haven't used since last summer. Think might even be an hour. PLEASANT smell and they work. I Love this product!

I put one in the skimmer or floater with the chlorine tablets ratio of 2 chlorine to 1 clear balance and replace evenly. MINE LASTS AT LEAST 1-2 WEEKS

I have no idea. It's basically the same chlorine, &ct. you put in pools mixed with a little Oxyclean. I find the tablets rather expensive, so I now go out and get bromine tablets from the pool supply people at 10th the price and have almost no odor and work just as well. I believe that the contents of either tablet simply dissipate into the atmosphere, the same way that chemicals in a swimming pool would, for good or bad...your decision. However the two tablets you put into the dispenser lasts me about 3 months and weighs about 2 ounces. Don't believe that has any serious consequences, but that's up to you. I would use far more than that in household cleaners over that same period.

The tablets are quite large, and they are not coated. Because of their packaging, they usually leave powder at the bottom of the bottle. The do seem to dissolve fully when taken, however, and don't seem to upset my stomach.

It seems to siphon @ a little over a gallon per minute, so 3-4 minutes. Best guess.

Yes, at the minimum. The colder the water and more turbid the longer it will take. If concern for cryptosporidium use with a filter or it could take 4-6 hours to kill them.
