    Katadyn Micropur Tablets provide fresh drinking water anywhere you go.

    Katadyn Micropur MP1 is the latest addition to Katadyn's Ultralight Series. This little tablet does it all. Micropur MP1 is the only product of its kind, EPA registered as a microbiological water purifier. Micropur MP1 tablets release chlorine dioxide, the same substance used in municipal drinking water plants worldwide. So not only is the water safe to drink, it also tastes great. Tablets are individually sealed for longest shelf life (5 years). Each of the 30 tablets included treats 1 liter of water. Wait time is as follows: 15 minutes for Viruses and Bacteria in all water, 30 minutes for Crypto and Giardia in normal water (60ºF, clear water), and 4 hours for Crypto in worst case water (39º F, very dirty, slightly acidic water, i.e. the kind you'd want to double pump with a purifier). **INCLUDES 30 TABLETS.

    Saving for an emergency

    • Familiarity: I've used it once or twice and have initial impressions

    I got these for a canyoneering trip down to Escalante, UT just in case the Miox Purifier and Katadyn Vario both failed from the very silty river water. I ended up not needing them which is fine with me. I'll just hold onto these for an emergency water purification situation. It's always good to be prepared!

    Works

    • Familiarity: I've used it once or twice and have initial impressions

    I've only used these once and I had no problems so I guess they did their job. I have only used iodine tablets (in survival school) prior to these and was looking to get some of those until I read about these. As stated in other reviews, no bad taste. The packets are hard to open so just make sure you have a knife or scissors or sharp teeth.

    Did the trick, no bad taste

    • Familiarity: I've put it through the wringer

    Used a copious amount of these during a camping trip in the Uintas. The water was pretty clean anyway, but we used these to make sure. 1 tablet per liter, 30 min wait, and no bad taste. Nobody got sick either. Recommended.

    Great Backup...I speak from experience

    • Familiarity: I've used it several times

    I've had these tablets in my backpacking gear for several years as a backup. I finally got the "opportunity" to test them out this year while backpacking in the Absaroka-Beartooth mountains (East Rosebud Trail). My trusty Steripen's batteries bit the dust midway through our week. (Pro tip: don't leave the batteries in the pen in between trips, even for short durations...it drains them fast, even lithiums). So we were forced to use these tabs. The only downside for me was the 4 hour wait time. I think there are other tablet/drop solutions that require less time...but you would have to compare exactly what nasties are killed. In the 4 hour time, these tabs take care of it all. I didn't even notice much of a taste. Good backup, but I would never use as my primary purification method.

    Bear in mind that 4 hour wait time is only for Cryptosporidium "cyst". It will kill regular Crypto in the specified 15 min treatment. But in regions with very, very cold water where Crypto can't survive and goes into cyst mode you need the full 4 hours to break through the cyst wall.

    All other buggers like viruses, bacteria, etc are killed in the 15 min treat time as well.



    Aquamira's website (as well as other companies) have very good educational materials on what's in your water and how filters and chemical treat and neutralize them. Very good information to read up on.



    Know they enemy and understand their weakness and you will be equipped with the knowledge to destroy them.

    Excellent, LightWeight, Does It!

    • Familiarity: I've put it through the wringer

    Traveled and lived for extended periods in the backcountry of Guatemala, Blue Fields Nicaragua, El Salvador and Costa Rica. I used a Katadyn micropur hand pump filter and then purified my water with tablets, specifically these tablets. Iodine does not kill cryptosporidium and there is a good deal of it in Central America, along with other things that do not survive the affect of these tablets. But some contaminant bugs and disease are attached to small particulate and its best to remove as much of it as you can, then use the pill. The Steripen won't work for these purposes either. Without a handpump you could also let the water settle and the sediment sink to the bottom of your reservoir for five to ten hours. That would help. I don't recommend it but it's an alternative. If you are going to drink glacial melt or canyonlands river water first use a t-shirt or pre-filter to save your hand pump. You'll love the simplicity! Great product! Compact! Stores easily! Be sure to use just one tablet per quart or liter and purify just one quart or liter at a time! Cheers! I have also used this on backpacking trips in the Sierra Nevada, Utah and Alaska. The handpump is a little heavy and if your trip is only going to last for a few days you might risk using just a t-shirt and carrying immodium. Personally I would not but some do it. For week-long or multi-week trips a handpump filter and tabs can't be beat and shouldn't be left at home.

    gets the job done

      I lead backpacking treks all summer long in New Mexico, and we always use micropur tablets. Granted we get them for free, so I've never had any inclination to use anything else, but I've gone an entire summer using these on some pretty sketchy water, and I've never gotten sick. Tablets don't break like pumps, they're quick, light, and low maintenance. just fill up your bottle, throw in a tablet, then enjoy 30 minutes later.

      Get the Potable Aqua 30 minute Tablets!

        http://www.rei.com/product/406032/potable-aqua-iodine-and-taste-neutralizer-tablets

        These tablets only take 30 minutes instead of 4 hours to treat water completely and the taste is great. I recently went on a trip to Africa and had these 4 hour tablets and thankfully someone brought extra 30 minute tablets. For similar price, it is worth it to have the quicker working ones. ALSO REMEMBER TO SHAKE SOME WATER OUT AFTER 5 MINUTES! you have to be sure to do this so the seals and edges of the bottle get treated as well.

        Iodine may be effective on bacteria and viruses, but it is not effective against protozoa that exist as cyst. So it will not touch Giardia or Cryptosporidium, the two most common parasites in North American waters.



        Iodine is providing you less treatment of bugs than these tablets. These kill everything in your water in 15-30 minutes except crypto cyst that require the full 4 hour soak time to be sure they are all dead. And bear in mind that you have to be in very cold water for crypto to go to into cyst mode. So most waters these work in the 15-30 min treatment time. But educate yourself and understand what conditions cause crypto to go cyst so you know for sure.



        Also long term Iodine use has consequences to your thyroid. So I definitely would not want to rely on that for anything but pure emergency use. But given it doesn't even touch parasites and I frequent cold waters from mountain snow pack I dumped Iodine years ago!

        Great alternative to iodine

          Great stuff. Very mild taste, I barely noticed it...way better than iodine. Packaging is a little difficult, but I got the hang of it after a few and only rarely needed to use a knife or something to help open the packaging.

          kept me healthy when I was 3 weeks from the nearest road

            I used these tablets everyday while on a 3 month expedition through the Congo River Basin. Some days the only water I had to drink was rancid swamp water. But thanks to these tablets I never got sick once, even my Baka Pygmy porters fell sick on occasion and they've lived in the forest since birth. I still ran my water through a pump so dirt wouldn't get in my teeth. And always plan in advance, because 4 hours is a long, long time to wait when you're out of clean drinking water!

            Light weight water system

              I have enjoyed using Aqua Mira Drops as my sole water treatment while on the trail, but recently I decided to pick up a Frontier pro filter to use in conjunction with the chemicals. The AM drops will kill the little stuff in 15 minutes (depending on water temp and turbidity) and then the filter will remove the big bad guys (Giardia & Crypto). So, I also decided to keep weight down, I would pick up some tabs (they weigh less than the drops).

              20 of the tablets weigh in at 0.5 oz in the packaging. Sweet!

              The packaging can be a little tough to open, so before leaving I snip the edges of the wrappers with a pair of scissors. This way when I use them I can simply tear at the snip. Still a little tough (especially if my hands are wet) but still manageable too.

              These tablets will leave a strong chemical taste to the water if the water is not ran through a carbon filter. During the day I treated the water and then filtered it so I would only wait 15 minutes. The carbon filter removed the chemical taste very well. However, at night I dropped in the tablets and then did not filter the next morning since the tablets had more than enough time to thoroughly work. The chemical taste definitely woke me up! Wow. It was strong! Good thing I had flavored drink tablets to add to it, although they still did not cover the taste completely. (And just for the record, I have never tasted a chemical taste using the AM drops, without filtering.)

              So, because of the strong chemical taste, I gave these a 4. Also, considering how expensive the pills are compared to the drops. But, I can only they assume that they do work (I haven't gotten sick anyway), however, they are the lightest water treatment option available. I will continue to use these, but I will definitely bring my filter along too!

              Another water system...

              Perfect

                Don't want to carry heavy filters around? This is the solution. These weigh next to nothing and you can have clean drinking water within 15 minutes and it kills anything possible after 4 hours. To me the 4 hours isn't a big deal, even if it was really questionable water I also carry multiple water containers so while one processes I can just drink out of the other. Great way to save +10oz off your pack weight.

                Emergency Essential

                  I always carry a few of these as a backup. I usually use a filter, either a Katadyn or Sawyer gravity setup, but always have a few of these as backups. I keep a couple in each first aid kit too. Lightweight and simple, these are an essential. Wait time sucks and they taste poopy. Get some emergen-c.

                  If I filled a 3 liter Camelbak Antidote Reservoir with flowing stream water in the mountains, would three of these tablets completely purify the full three liters or would tripling up not have the same effect as one tablet with only one liter of water?

                  Best Answer

                  Three tablets would purify three liters in one bag just as well as doing it one liter at a timer. Make sure you bleed the system after 5-10 minutes once the tablets are fully dissolved, then again after 20-25 minutes to flush any bacteria out of the tube and bite valve. I HIGHLY recommend always letting it sit for at least thirty minutes.

                  Do I need to take some of the purification tablets as well? I'll be spending 8 days in the back-country of Belize and could really help knowing how to handle their water. I've used the PUR Guide here in the states with nothing but great results, but what about there in Belize.

                  can you use just these tablets and no filter? or are they only used in conjunction with a filter?

                  As is, kills bacteria, protozoans and viruses without the need for filtering. These just leave a bit of a chlorine smell and the faintest taste. The only reason you might want to do any filtration would be to remove particulates. The only thing you want to be aware of is the quality of the water and how long you need to allow the tablet to work. That said, in most places in the US, usually safe to drink in about 30 minutes. Effective stuff, but running water through a filter instead is a much more pleasurable experience, especially when the water starts warming up and the chlorine taste starts intensifying.

                  I am traveling to a foreign country with my two year old and the water is not safe to drink. He has a bad habit of getting bath water in his mouth. Could I treat the water with these and then feel safe if he get some in his mouth? How long should it sit in the water? Will it be ok for his skin? Can we wash dishes with the water that has been purified with these?

                  Best Answer

                  You're going to blaze through enormous amounts of tablets and money in the bath (1 tablet per liter), and by the time they treat for all possible contaminants (15 minutes-4 hours, depending on the type), the water is going to be no more than tepid, at best. Given that he's two, you may want to bathe him yourself so you can keep him from getting the water in his mouth, and limit the bathing, instead keeping up hygiene by using antimocrobial wipes whenever possible. Most municipal water supplies in the US use some form of chlorination, as do swimming pools, and these tablets are for potable water, but repeated and prolonged, concentrated soakings and steam isn't something I would want to expose my kids to. In the kitchen sink, a good antibacterial dish soap, along with as hot a water as you can stand and drying thoroughly should do the trick on the dishes. If available, the dishwasher is going to be the best solution though. Great question, but it sounds like this one falls to Mom and her magic washcloth.

                  I'm also going to Peru this summer. Jason, would you take these over the MSR Miox Pen? I'm thinking of using both? Will these pills clean the lid, bottle, and threads of a nalgene the way MIOX will?

                  Best Answer

                  The Micropur tablets are all you need. With the Miox, you still have to wait. On the other hand, if you want water you can drink almost immediately, the Steri-Pen is a couple stirs and you're good to go. With any treatment, unless the chemicals, or light, or electrical current makes contact with surfaces like threads or the outside of the bottle, residue won't be treated. A good trick is to use one bottle exclusively for collecting the water, and then transferring that to the bottle you'll be drinking from for final treatment. Miox or SteriPen, bring extra batteries.

                  I'm going with two girlfriends to Peru to...

                  I'm going with two girlfriends to Peru to hike Machu Picchu next month. We're trying to decide on the best option for purifying our water on the 5 day trek. We're going with a tour group and they will boil the water for us, but we want to be extra cautious. Would it be acceptable to throw one of these tablets into a liter of their boiled water and drink it 15 minutes later? Also, I have a 3 liter pack -- could I just put 3 tablets in the already boiled 3 liters of water IN my hydration pack? Thank you for any advice you may have for us!!

                  Best Answer

                  I know you want to be cautious, but if they have really boiled the water (you've witnessed it), then there's no reason to purify it any longer. Once you bring water to a rolling boil, all of the microbes that will make you sick (protozoa, bacteria, viruses) are gone. However, I would still carry the tablets just in case you run into water that you want to drink that hasn't been boiled. By putting one tablet of MicroPur into a liter of water (X1 Nalgene bottle), and letting it sit for about 30 minutes, you will have safe drinking water. I would be very cautious where you get the water (DO NOT get water from stagnate water source...only use flowing water like from a stream or river). Where you get the water from is as important as how you treat it. Also water around the lip of the bottle or on the lid isn't treated and can make you sick. Make sure you clean the bottle (especially around the lip of the bottle where your mouth will make contact) thoroughly before use. Drying this area of all non-treated water will definitely help. Washing hands (or using anti-bacterial gel) and keeping things as clean as possible will help to make sure you stay healthy. Treating the water is only part of keeping yourself from getting sick!

                  I'm curious, Is it advisable to purify 3 liters at one time in the same container, with three tablets, of course? Do people do this?

                  Best Answer

                  I think this is ok as long as you allow for the proper dwell time (20-30 minutes for giardia and 4 hours for crypto). I would also recommend stirring the water to allow the chemical to effect all of the water in the container. Also don't forget to treat the container itself, meaning the threads and the lid (if applicable). You only need a few bugs to make you sick...

                  I think Katadyn is estimating the longest possible shelf life while still retaining efficasy & bc.com is taking the safest approach. Where chlorine dioxide is concerned, I'd say three years is more than enough shelf life.

                  I have not been to Africa but these tablets are great, little taste and have used them with multiple water conditions. You don't want to chance a filter breaking and then not being able to get the parts. Be sure to get a shit ton of these things though because 1 tab only treats 1 liter. Also, use only clear bottles, because of the amount of sunlight if you are able to put the micropur in the bottle and then let it sit in direct sunlight you will get the UV exposure along with the chemical treatment. About 5-6 hours in the sun will help as well. You can always double up on filter and chem treatment, can't hurt. Hope this helps, good luck in Africa.

I know you cannot use Iodine for extended use but are there time limitations to the use of this product. I will in the nevada wilderness for 55 days and I need a cheap water purification solution.

                  Best Answer

                  I may be a little late on this answer---but: Micropur tablets used as recommended: produce Chlorine Dioxide at a concentration of 4 PPM (parts per million). The Environmental Protective Agency currently recommends Chlorine Dioxide as part of the water treatment process for U.S. cities, with allowance of a higher concentration than Micropur gives.

                  However, the other part of the city treatment process is microfiltration to remove organic matter from water.

                  If your water is not clean to start with, you can get a by-product,chlorite, which is not good for small children ----or you, with long-term consumption.

                  Bottom Line: Use Micropur where the water is pretty clean, if you are going to be drinking a lot of it.

                  Other Chemicals: Main drawback for iodine is that it does not kill Cryptosporidium protozoa. Main drawback for chlorine liquid is: when you use it in water that contains organic material, you get carcinogenic by products.

                  For a long solo trip in Nevada: I recommend the Katadyn Hiker Pro microfilter. I use Micropur tablets as a backup, or in Asia and South America with microfilters to kill viruses that filters don't remove.

                  I'm a bit more paranoid, especially when hiking in heavily travelled areas or areas where cows or sheep may be present. Given the water temp and the general area, this would be my plan:

                  Fill all water containers at night and disinfect all, especially hydration reservoir (4+ hours overnight)
                  Any empty bottles after breakfast also get filled, disinfected for 4+ hours while hiking, with the exception of any water container on the outside of your pack that will warm with sun and ambient air temp. These get used to replace the hydration reservoir mid-day, if necessary, and are, in a perfect world, refilled and disinfected at the same time.

                  The idea is to always have potable water while also disinfecting the remainder of your water store (if you don't want to carry a lot of water at any given time and water will be readily available on your trip, you can use a UV pen as a primary disinfectant, with chemicals for backup). In more remote areas where the water is clear and your altitude is high (less chance of upstream contamination), 30 minutes would be sufficient, for me. I have never gotten sick through this practice, which is the whole idea of disinfection. Others, like Randy, have probably not gotten sick with their practice either, so it's a matter of choice, risk and your own personal paranoia scale. I would never go less than 30 minutes and no one I know would either.

                  I'm going to India . What about using it...

                  I'm going to India . What about using it for hotel water not suited for drinking?

                  These tablets will work with non-potable hotel water, but I personally find tablets to be a pain because they take longer amounts of time to ensure water purity.I travel all over the world with my SteriPen. They're a bit more expensive, but it's worth every penny, I don't have any additives in my drinking water, and I know they're clean and safe.http://www.backcountry.com/store/brand/100000008/Hydro-Photon.htmlIf you're feeling the hocus-pocus vibes, you're not alone. I've got good friends in the beverage packaging and water purification systems industry who swear by UV, and the independent lab testing for SteriPen sold me on the concept.Here's the nitty-gritty details:http://steripen.com/proven_in_lab.html [The overview]http://steripen.com/testing.html [The hefty lab stuff]

                  Why not use Micropur tablets before...

                  Why not use Micropur tablets before filtering? Everyone has said that they use them afterwards.

                  Best Answer

                  It's a simple balance of chemistry. The filter removes large elements, which means there's less for the agent to have to 'sanitize' when you drop in the tablet. By simply filtering large elements, they consume a large portion of the chlorine dioxide and there isn't enough left to kill the especially nasty microbes in your water.
