    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.

    I received the unit and quickly began to install it. While installing I was not paying much attention to the installation manual and broke the ceramic cartridge filter. I could have cried.. I called the company and spoke to Jim who quickly shipped me a replacement cartridge at no cost. Great customer service and I love the unit and everything about this company. For years I have wanted a water ionizer and could never afford or justify one. Two of my yoga friends have now purchased Pure Hydrations along with the Hydro Bullet and we call ourselves the “Pure Hydration Girls”. All of us have better looking skin and much more energy. This unit defies the saying “Cheap is not always better”.

    I have installed the Pure Hydration unit in my clinic at Joe Gibbs Racing and it was a hit, INSTANTLY! My athletes love consuming the water because they understand the education and science behind it. I teach my athletes how to improve their health, and then let them make the decision if they want to use something or not. In this case, every athlete chooses to drink the water in the clinic vs any other sports drink offered by our facility. Not only is the product great, but the customer service is amazing. Jim actually cares about his customers, and makes working with the company easy and accessible. I would highly recommend the Pure Hydration products!

    I OWN an Enagic Kangen ionizer, but I wanted to buy an ionizer for my daughter that I could actually afford. And if this one works out well, I plan to buy another one for the other daughter. Kangen is priced so that only rich people can afford, or crazy people like me!

    I also submitted a review in Amazon where I see that you sell Pure Hydration. The unit is nothing short of amazing. I cannot believe the difference in water quality from this unit compared to tap water and purchased bottled water. Even my wife the skeptic won’t drink any other water. Well done!!

    I love the water and definitely recommend friends and family to purchase from Cosan/USA! I called the company and spoke the nicest man that took time to answer all my questions. I learned that this is a Christian owned and operated company and could tell by the way I was treated. Three of my family members now own a Pure Hydration units and we are all about this company and the movement they represent in improving the health of the world.

    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 in October, 2015 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, Ive 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.

    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!

    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.

    It was a quick simple install with significant difference in water clarity and taste. As far as the Alkaline and Hydrogen, I can’t tell any difference but I trust it does what they claim, worst case I have clear good tasting water. Wife and kids are using less bottled water and are refilling the ones they use, that’s good enough for me. Highly recommended the unit on just how easy it is to install, I did not use any tools and installed using the faucet diverter in 5 minutes.

    I have to say that it is rare that someone changes my opinion once it’s been made. Initially due to a misunderstanding, I didn’t have a good opinion of Cosan/USA because I was suspicious that it all was part of a sly scam (there are so many these days). Now seeing how quickly you responded to my emails and sincerely made things right with me – the customer, even going so far as to offer a free Pure Hydration 4-pack replacement cartridge set as an olive branch for any misunderstanding. Your goodness has made me see your company in a much different light. I am amazed at the professional and dedicated customer service shown to me and will accept your gracious offer of the 4-pack replacement cartridges in the spirit it was made. I will be registering my Pure Hydration Alkaline Antioxidant Water Ionizer this week and will be leaving positive reviews for your company. Once again, I thank you Mrs. Charlene for taking my concerns seriously and doing all you can to fix them.

    Thank you

    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.

    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.

    So glad my husband did some research and found an alkaline water machine for under $2000. I love this, and the water routinely tests between 8.5-9.0. We have well water, so we don’t have any of the “additives” of city water sources.

    I purchased the unit because I consume a gallon/day to remain hydrated and I wanted high quality water. I never noticed how lousy tap water and the bottled water I purchased tasted until I drank this water and then tried the prior water. Yuk!! Even my wife, who was skeptical of the purchase commented on how good the water tasted compared to other sources of water she typically drink. I use the water for cooking, coffee, tea, etc and fill up a gallon jug daily to take to work. The unit was easy to install. I connected to my water and used enclosed faucet instead of diverted valve. No issues installing filters and no leaks. The unit is well built amazingly simple to operate and makes exceptional water. Try it for a few days and you’ll be hooked!!!!

    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.

    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.

    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.

    how much magnesium content is in the water per 8oz glass after the water runs through your system? What other additives are added to the resultant water?

    I’m concerned about overdosing on certain minerals or longterm toxicity issues, and would like to know what is in the resultant water and how much content of what your system adds. Can you help with these questions/concerns?

    • jim

      The information your looking for is the recommended daily allowances found on the last page of the NSF Report. They are the last four items of the NSF report (magnesium, zink, sodium, and potassium). No worries when it comes to over mineralization – the amounts found are very low and are based on a per liter basis.

      Great question and thank you !!

    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, could you please provide 3rd party verification for the level of hydrogen produced by your Pure Hydration system (Molecular Hydrogen rating of 1,500 parts per billion (PPB))?
    Also, could you provide data on fluoride filtration as well?

    I recently–this evening, in fact!–purchased this system from Amazon and am very excited about all it has to offer.

    Thank you, Dan

    • jim

      Hi Dan,

      Sorry for the delay in responding.

      Sorry, but we do not offer third party testing on Molecular Hydrogen due to the fact that you can perform the 3rd party testing of H-, pH, and ORP reduction yourself in a non-laboratory setting. We do provide certified NSF testing as to reductions and recomended daily allowances of key minerals that you can find on our site – simply click the NSF link.

      Thank you for your purchase and please drop me a line and let me know what you think.

    I just ordered and received the Pure Hydration counter top (which I am installing now), and the Hydro Bullet portable unit. I started using the Bullet right away and can tell you I had results immediately as I consume copias amounts of water and usually when thirsty down a large bottle of my filtered water. I was full but in a little while was thirsty again. When I was about to do that with the Bullet I found that 1/4 of the bottle made me feel “satisfied”, and since drinking the water out of the Bullet am satisfied (apparently due to the more efficient hydration factor) and my rash is dissapearing, slept better last night. This is the initial reaction. Love your Product!!!

    I wanted to let you know the replacement shower piece arrived on Monday. It is installed and working great! I was overwhelmed by your kindness and customer service! I was delighted to receive the faucet attachment as well. Thank you so very much. Very unexpected but very appreciated! I hope to install it in the next few weeks. My friend recovering from breast cancer will be with us for about 3 days and looking forward to sharing the water with her. I’ve been drinking the water at the temperature it comes from the unit. 98% of what I drink is water and a few cups of coffee some days. I’ve had only a few sips of pop in my life glad I didn’t like it 😊 So having this water filter is wonderful. I like the taste.

    I bought my cosan pure hydration last fall 2017. I integrated with my reverse osmosis system with my potassium chloride water softner system. My water is super clean, soft. I lost weight from 250lbs to 1993 lbs just drinking molecular hyxrogen water. I invested in shower filters too. I will invest other products on this site. I bought ph tester and oxidation reduction potential meter to monitor quality of my water.

    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.

    Dear Jim,
    I just got my replacement filters and noticed that the #2 is no longer a ceramic filter. Was just curious as to why and if the change in #2 filter is the reason why the #3 will need changed every 3 months now. I got the full 6-months out of my unit on well water and it works fantastic. You can see the iron started to build in the ceramic but the water was still crystal clear and smooth. I pH test around an 8.0 🙂 Just wanted to double check. I just got the Pure Hydrogen flask and am getting ready to hook up the shower system. Love your products – please don’t change a thing! Working great on my West Virginia iron ridden well water! Haha
    Have a blessed evening!

    The No. 2 filter change to a one-piece solid type cartridge was due to the overwhelming number of users across the U.S. that did not have the strength in their hands to open or close the unit. Our first attempt to remedy the situation was to incorporate spanner wrenches to make opening and closing possible, but still, we had many calls from customers that did not have the strength to open the cartridge even using the wrenches. Ultimately we arrived at incorporating a solid carbon block cartridge with the same reduction potential and infused it with silver for increased anti-bacterial potential. There is virtually no change in the antioxidant or reduction performance with the with the new No. 2 single piece cartridge,

    The addition of a 2nd No. 3 cartridge stems from many well water users throughout the U.S. reporting declining pH levels around the 5th month. We elected to add a second No. 3 rather than sell individual No. 3 cartridges or developing a stand-alone 5-piece well water pack. We did not change the price based on the fact that the well water users were not receiving the 6-month advertised life – something that they purchased but did not receive. By changing the No. 3 cartridge every 90-days, you will ensure a 9.5 pH rating coupled with a molecular hydrogen count of 1,500+PPB and an ORP of -450+.

    Blessings, Jim Lynch

    Jim – That’s great! I actually never thought about trouble opening 🤔. I guess my iron isn’t as bad as I thought since mine still stayed around 8.0 to 9.0… kind of in between. It’s a bluish to almost purple when I run a test. Love the shower by the way! Got it hooked up last night and I wanted to stay in because it I kept smelling lemon. So refreshing. The hydro flask is awesome. I can’t get over how my water is colder in it. I’m so thankful mine works great and stands up against my well. I was worried my iron ridden water would shorten the life of my filters but nope!

    Thank you again for great products! I’m totally addicted 😊
    Thanks for getting back to me. Have a great weekend!!

    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.

    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.

    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

    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.

    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

    This 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 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.

    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.
