Pure Hydration the Next Generation from Cosan/USA on Vimeo.



Why pH balanced? Why antioxidants and natural minerals? Water serves as the most important and simplest way to improve our health. Alkaline water aids in nutrient delivery and cellular absorption throughout the body improving removal of toxins through the lungs, skin, kidneys and digestive system. Many health professionals recommend the benefits of Hydrogen-rich Alkaline water – and Cosan/USA takes a revolutionary all-natural approach to water ionization using NO ELECTRICITY and no waste.

Pure Hydration represents the second generation of all-natural water ionization globally distributed throughout the world. Transform ordinary tap water into clean and healthy ionized alkaline at your faucet or cold-water supply valve in minutes – includes everything needed to install. The unit resets to new tolerances upon filter cartridge replacement.

Alkaline Antioxidant Water will improve your body’s pH balance, digestive health, sleep, weight loss, skin tone, blood circulation, and detoxification. Alkaline Hydrogen Rich Water is known to slow the aging process by adding abundant anti-oxidants that neutralize free radicals caused by the average American lifestyle and diet. The price point and performance reflect our core biblical approach to business in delivering a health improving appliance at an affordable price. The performance ratings of Pure Hydration render it a stand-alone world-class contender with a .02-micron pre-filtration rating. Healthy antioxidant water begins with proper pre-filtration, without which, health benefits decline.


* NOTE: Source water quality plays a significant role in any water ionizer’s performance and can increase and decrease pH ratings, ORP reduction, molecular hydrogen count, and rated filter life.

Pure Hydration Logo

Pure Hydration is an all-natural non-electric Alkaline Antioxidant Water Ionizer that outperforms the best-selling electronic water ionizer on the market – Kangen’s SD-501 that sells for $4,800. The system produces Alkaline Antioxidant Water by way of four proprietary stages of reduction designed to restructure drinking water for optimal health and remove contaminants 150 times smaller than the average electronic water ionizer.

Stage 1 – 6-month life, is a granular activated carbon (GAC) made from coconut rated at .05 microns. It effectively pre-filters incoming water to remove chlorine, sediment, volatile organic compounds (VOC’s), foul taste, and odor from incoming water.

Stage 2 – 6-month life is, a solid activated carbon block (CTO) made from coconut rated at .01 micron. The carbon is infused with silver for fresh-tasting water and reduction of germs. The design contains 50% more micro-pores than wood and coal carbon, making it easier to absorb volatile organic chemicals known to be challenging to remove from water.

Stage 3 – 3-month life, is a solid activated carbon block (CTO) made from coconut rated at .01 micron. The block is infused with magnesium that forms a carbon/magnesium bond to create molecular hydrogen (H2). When water (H2O) and magnesium come in contact with each other, Molecular Hydrogen is created. Hydrogen represents the smallest known element on earth, and molecular hydrogen (H2) represents the smallest known antioxidant. Its .074 nanometer-size allows for fast cellular absorption and quick neutralization of free radicals associated with the American lifestyle and diet.

Stage 4 – 6-month life, is a spun fiber cartridge made from spun polypropylene fibers rated at 1.0 micron. The filter represents the final stage of reduction and serves as protection for the onboard electromechanical solenoid.

Pure Hydration creates clean, healthy, Alkaline Antioxidant Water at an average cost of $.05 per liter. Alkaline Antioxidant Water balances your body’s internal pH, neutralizes free radicals, reduces reactive oxygen, and increases cellular hydration for increased energy, improved health, and a stronger immune system.

    I want you to know this system is the best thing to happen to me in ages. I can eat almost anything now, my stomach issues with my hiatal hernia are about non-existent and I feel so much better. My purpose of writing is to send you this photo. Yesterday the water department did a flush of the water pipes in our development. What scary things came out of the pipes? This is the example. My cups are white – the brown one is what was coming out of the kitchen faucet to which the CosanUSA is attached to the same cold-water valve under the sink. The clear water is what came out of the filter system. If this isn’t proof your system works, I don’t know what is. The two cups of water were drawn within 5 seconds of each other. Thank you for this marvelous system at an affordable price. God bless you and yours.

    I was introduced to Pure Hydration alkaline water and have experienced many health improving benefits that support the many hours I spend in the gym training. I’ve noticed increased energy levels and shorter recovery times with considerable decreases in muscle soreness. Besides the benefits to my training, I’ve experienced great improvements to the look and feel of my skin. Not only does my skin look healthier but its softer and smoother than t’s ever been. I highly recommend Pure Hydration to anyone looking for a competitive athletic edge or just all-around better health.

    I installed the unit myself and only needed a couple of hand tools. I have well water and find the taste of my water better than my friend who has his Pure Hydration on city water. My whole family loves the water and we all find ourselves drinking more water and less cola’s. My mom actually stopped drinking cola and carries the travel unit with her when she travels.

    We purchased the Pure Hydration system a couple of months ago at the Green Festival and love it! The water tastes so much cleaner, and I love knowing that the alkaline water I use every day to make fruit infused water is even better for me than before! Thank you for making such an amazing product that is affordable!

    The system was relatively easy to set up. I connected it to the faucet, so it was very easy to go from regular water to filtered water. Ordered two glass pitchers and keep one in the refrigerator and the other under the spot. Smooth-tasting water with no chlorine taste.

    Hi there, You have done an excellent job. I’ll certainly digg it and personally suggest to my friends. I am confident they’ll be benefited from this site.

  7. jim

    wow this water is terrific. Had another brand before and there is no comparison in terms of bottle quality (double wall) and the care in removing contaminants period plus energy level. Worked two days removing a Bird of Paradise plant that was 50 years old it grew inches.12 inches deep in a 3-foot by 6-foot cement boarder planter. Took two days without any fatigue filled up two city Recycle Cans.96 gallons each. Only drank one container of water each day. Could not believe I was not tired at 69 years old.. Don’t throw your money away on cheaper brands. This is the best product.. Can even use on your face for hydration prior to putting on your products and I even layer in between them. WOW !!!! Thank You COSAN for an outstanding product. . Wonder Customer Service.

    I have had the Pure Hydration Filtration System for exactly two years. It has been a great adventure! First, let me simply say, it would be impossible to find better tasting water anywhere. And, if you drink the quantity that your body needs, you will feel all the promised benefits within a couple of days. Do it!!!
    After installation I measured the pH of my water and thought it not alkaline enough. I contacted Cosan for answers, and I was sent a good quality testing agent immediately. Sure enough, with a good testing agent the pH of the water was 9 or above.
    Sometime later (more than two months), I found the pH level of my water was dropping to around 8. I wondered how my filter was going to last six months if the pH was already dropping. So back to Cosan and Jim Lynch I went. Jim asked me to begin a period of testing pH levels. I did. Each week I tested the pH of my water and photographed the results and emailed them to Jim. By taking the pictures in the same place and in the same lighting every time, a record of changes was developed. This was interesting and gave me the feeling of being valued as a customer. At the end of the testing period Jim informed me that Cosan was going to be changing their filter-bundle to include two alkaline filters. Henceforth, those filters would be changed every three months. I like to think I had a little part in Cosan’s research.
    This all amounts to healthy, wonderful tasting water, from a unit that takes only minutes to install. The joy of feeling the improved health and vitality is priceless. And, the big bonus is buying from a company company that cares about and listens to its customers.

    I am really pleased with my Cosan Pure Hydration Water Ionizer. Since committing to an alkaline anti-oxidant lifestyle, I can see and feel such a difference in my overall health. So many health issues have subsided since I made the choice to clean up what I choose for hydration. I am 7 months in as a Cosan customer and could not be more pleased with the quality of water and the support from the company.

    Making a choice to drink healthy water led me to making better choices in many other areas as well. I thank Cosan for all the information on this site about research – what foods are healthy and alkaline, all about Molecular Hydrogen, and easy installation videos. You guys have it all covered. Thank you.

    his Pure Hydration system works great. I’ve been drinking it for about 2 weeks now, and I feel much more energetic since i’ve been on it. Usually, by the afternoon I would feel very tired and sluggish, but ever since I started drinking this ionized hydrogen infused water, the afternoon’s are not a problem, and I get a lot of work done now.

    I love discounts! Makes good products even better. Thank you.

  13. jim

    Great products, awesome customer service! I have highly recommended CosanUSA’s Pure Hydration and filtered bottle water container to my family and friends. The Pure Hydration is very easy to set up and works exactly as advertised. The water container is perfect to have when on-the-go. I even filter bottled water from the store just to have my drinking water at it’s purest ph levels. (Most bottled waters I’ve tested were very low in ph levels) Customer service is easy to get in touch with and inquires were always professionally handled. These products are absolutely a great investment in keeping your body healthy! Check out their youtube comparison video: CosanComparison1

    So far so good water taste great. Have been using a little over a week. Tested 9+ alkalinity, over 1 ppm hydrogen, and 700 +++ ORP. Quite satisfied so far. I have well water which I run through a Morton whole house self cleaning filter. I then run it through a 5 micron large canister filter then through a water softener. Have high iron and manganese in my well water. Tried a non electric unit that’s name started with an H. Could never get any tests as good as Pure Hydration unit even from day one. I like the fact that I can change the filters whenever I deem necessary. Trying to drink 1/2 my body weight in ounces daily. After a week i seem to be feeling better. I was drinking RO water which is acidic not good for you. I found this out after starting to feel bad after several months of it.

    My problem was an odor in one of the filters.
    I was contacted within 2 days by Jim Lynch we talked and he explained the problem. He worked out a solution in replacing filters. I was very pleased, cause I understood what he said. Very happy he took time for email and phone call.
    Thank you

    I just installed unit and gave a 5 star rating but in all honesty I have not used machine much yet – please take that into consideration – do not want to mislead.

  18. jim

    I have had my machine for 4 days installation was easy, Followed all instructions water taste is great. Have not tested the PH or H2 level yet waiting for my test kit to arrive. I have no doubt everything will be as advertised. The customer service is great I purchased the machine direct from your company and it arrived at my door the next day. Also purched the shower system and installed it I love I don’t want to get out of the shower it makes you fell squeaky clean. I have been using another manufactures portable H2 water generator for about 4 weeks and have noticed significant increase in energy levels and exercise recovery as well as other health improvements and that machine only produces H2 at 1,0 to 1.2 PPB I will update after continued use. So far I am pleased with my purchase and with your company. I work out 3 days a week with a personal trainer and have for the past 5 years. I am a very busy Real Estate Agent and work many hours. By the way I will be 74 years old next month. I am also a self taught naturopath I was forced into educating myself when my late wife developed cancer.

    The unit shipped the same day I purchased and I received an email notification with tracking details. It operates as described and works really fast in creating hydrogen. I’ve used now for 5-days and can see and feel the difference in my skin.

    Fast shipping and great customer service responce on questions that I had regarding cleaning. Cleaned the unit with critic acid in accordance with the manual and customer service and am able to report that all is functioning properly. Researching more about the benifits of this product and see lot’s of information on free radical reduction. Love both the product and the company!!

    I find it a great product and easy to use. I’m deducting a star because it did not ship the same day I ordered. Apparently, you must order before 3:00 EST for same day shipping and they do not ship after 4:00PM EST for us west coast customers.

    My physical last Fall showed my kidney function to be one step away from needing dialysis. I asked my doctor to run the test again this year because I had been using the Cosan water system for about 4 months.

    The test came back within normal limits and also hair, skin and elimination system that improved remarkably. I had the opportunity to use this water at a friends home for 2 months before I bought my own and this sold me.

    I will continue to recommend Cosan and have to doctors and fellow athletic friends and family.

    My best,

    Purchased this unit after I viewed the comparison video and can say that it’s everything that the company claims and more. I experienced an increase in energy and lost 8 lbs. the first ten days drinking the water. Our water in New Orleans isn’t the greatest and this unit makes all the difference in the world. I find myself drinking more water and it’s not intentional, it’s like my body knows this is good for me. A great product and simple to install.

  26. jim

    Thank you for your kindness. I have had one of your units for only one week and I am seeing great results. Even my massage person who I have not seen since I started drinking hydrogen alkaline water could tell a difference in my body and skin. Thanks for making a great product. These units are for my kids and I have commercial properties I will be buying units for soon.

  27. jim

    Called customer service and was transferred to Jim who knows a lot about water and health. I shared with him that I have cancer and need to get alkaline. He shared that I needed God above all things and prayed together with me. Shocked and sold that this company is for me.
    Thank you Jim!

    I researched an alkaline machine for a couple of years now. I have a plant based diet and I was constantly purchasing alkaline water from stores, and other people who had their own machine. I figured it was time for me to get one myself. So I did the research and I read the reviews on this particular alkaline machine. I decided to just make the purchase. The machine was easy to install, a lot easy than I thought. After you hook the machine up the directions say to run it for 20 minutes I decided to let it run for 30 minutes. This is the best tasting water I’ve ever drank. I’ve even given some to my grandparents who are in their 80s, they’ve noticed a difference. I already have a pH strips so I tested Fiji, store bought alkaline water, amd my water from this alkaline machine. I’m so glad I did this purchase now I’m in control of my water and you only have to refill the filters every six months.

    Working fine water taste great!


  31. jim

    have contacted Jim Lynch as I had questions about content of the filters. He was very helpful explaining.
    I love this product. Water taste awesome! I got high readings on the OPR in range of 500s….on the negative side. I am quite content! Now my next project is to mount it under the sink. I hope it will work.


  32. jim

    This was a bit of a struggle to set up, as I was not prepared to install the shutoff faucet, but with the help of a friend we got it done. Delicious water!

    Mi english no good. Cosan/USA good people to sell me Pure Hydration in Barcelona. VERY VERY great machine!!!


  35. jim

    Over all I’m satisfied with this system. I’ve not had a chance to test the water to see what level of ph yet. The reason for 4 stars and not 5 is that this water tastes good in glass containers but horrible in plastic. Tried several different types of plastic but it’s not desirable in any plastic container.

    Yeah baby! Every now and then you find a diamond on the internet. This company out sparkles the competition and will no doubt surface to the top of the players board. Man I love to get a good deal and the Pure Hydration ranks up with some of the best deals Ive ever been blessed with.

  38. jim

    I want to thank you for your kind support regarding the purchase of our Pure Hydration water system. My husband and I wanted to purchase an oxidating water system for awhile but we were unable to find one that was not price prohibitive. When we became aware of the Cosan water system we were excited to find a reasonably priced unit and decided to give it a try.

    We are very happy that we did. The water tastes wonderful and each of us has noticed health benefits. My skin is visibly less wrinkled, I feel great and my BPM while exercising has gone from elevated to normal. My husband has dropped a few pounds without changing his diet.

    We will be traveling next month and will be using our Hydro Bullet so that we can continue our water regimine. Thanks again and feel free to share this information if you want to.

    It’s been only 4 days since I purchased my pure hydration ionizer and I already see the difference from other waters, the water it produces, is much better. I feel a difference in my body after I drink it, if I feel this way after only 4 days…i can only imagine after a month or 2. I was intimidated after opening the box, to find out the ionizer was un-attached, and that I had to assemble and put it together myself. I thought it would be a painstakingly long process to put it togetber, even after briefly looking at the instructions manual, but after I watched the video instructions, I calmed down when I realized how simple it is. Something I thought would take me hours took literally only 6 minutes to put together by myself. After I hooked it up to my sink, I had a couple of quick questions and called, a lady answered my questions with excellent customer service. Before I purchased this product a was about to spend 2000 dollars on a well known ionizer…i did a little Google research and found an unbiased opinion on it, according to what I read, the ionizer that cost 2000+dollars do not do anything other ionizers can’t do, from what I was reading, they have a reason why it’s so expensive, but I won’t get into that. I heard alkaline water is better kept in a glass so I drink it that way.

    Hi to you Pure Hydration people; I had to check this one out and let you know. At home I have had a Jupiter Melody water Ionizer for the past 5 years and decided to do a TDS (Total Dissolved Solids) check on the Melody Ionizer compared to the TDS in the supplied municipal water and also a TDS check on the Pure Hydration. here are the results: TDS on the municipal water is 42 ppm; the Melody Ionizer 45 ppm and the Pure Hydration 121 ppm. Results which prove to me that an electric water ionizer doesn’t add minerals to the water while the Pure Hydration does add beneficial essential minerals. Another added value and selling point for us.

    Since May 2016 I drink water that increases PH in water and remove the acidity in my body. My life has changed! My rheumatologist even removed 3 drugs, only 3 months of use. The pain of fibromyalgia decreased by 50%. The nodules I had on my fingers and feet disappeared. My hands were unable to close and open at 100%. Sleep has returned. Chronic fatigue and pain became less unbearable. My face and body are less tense. My family have seen an incredible improvement. Degenerative osteoarthritis that I suffer since I was 25 years old will surely be a thing of the past in some years. I asked my rheumatologist if she had ever heard of the water with pH on her patients had told me yes, so I asked her why she had never talked to me before ???? She replied that medicine is not made. The doctors all know and say that I have to drink water but those that I talked about this machine to and I even offered to testify about my experience to some associations (of auto diseases -immunes) in the area have NO interest. They only talk about medicines everyone wants as if patients have little believe the importance of the water that drinks. And the crime of water bottles to enrich companies and pollute our planet. The water in my town is super good and this machine removes the chlorine in the water and add pH. There is so much information about the acidity of the body all the diseases that develops …. Even cancer …. The only distributor of this Pure Hydration machine in the province of Atlantic and the province of Quebec is Pierre Moreau and the machine sells $495.00 in American money. So inexpensive for your health and the land.

    Haven’t bought a machine yet but I have nothing and everything to lose. I pray this machine works as good as the reviews say. I currently purchase Poland Spring 3 litter bottle and they’re not always good.

    The Pure Hydration Alkaline Antioxidant Water Ionizer works well and delivers what it promises. I am not very good at installing or hooking up things but even I got it working so anyone should be able to also. BUT I must say I truly was amazed by the prompt and courteous customer service.There was a small problem that the company IMMEDIATELY addressed and smoothed over.There aren’t many times I change my mind after a first impression about a company but Mrs. Charlene from Cosan/USA did a great job of changing my mind with the level of professionalism and actually caring about the customer. Thank you again Mrs. Charlene!!
