The Nexus X-Blue Water Ionizer - Outstanding!

The Nexus X-Blue Water Ionizer is not only the best bargain water ionizer we have, but it is also a truly outstanding water ionizer! The quality of the X-Blue water ionizer is unmatched by any other water in its price range.

It all starts with quality design and manufacturing


The Nexus X-Blue water ionizer is made by Ionia, the oldest and largest water ionizer manufacturer in Korea. The X-Blue is a fantastic, five-large-plate, top-of-the-line ionizer. There is no better water ionizer (not even close) than the Nexus X-Blue water ionizer in this price range.

Nexus has a patented method of spraying their water ionizer plates to ensure the plate is thoroughly coated with platinum and that no dust or air-bubble gets trapped into the coating. This coating process is tested and proven to increase the surface area of platinum for the maximum ORP.  See this plate comparison.

All water ionizers are tested before leaving the warehouse and factory for quality control purposes. New filters are installed, but there is usually a small amount of residual water, so plugs are placed on all ports for shipping. Please follow these guidelines for removing the quick-connect plugs.

  • Filters last for approximately 1,000 gallons of water poured through the machine. Replacement filters cost $79.95.
  • Filter Indicator: A symbolic filter indicator icon tells you about the remaining water filter life. Optimum performance is ensured by always changing your filter on time. In addition to the symbolic indicator, a new indicator light will flicker when your current filter life is up, reminding you to change your filter.

  • Note: Every machine is tested, both at the factory and warehouse, for quality control purposes. There is no water in your filters, but there may be a small amount of moisture in the machine itself, this is normal and will cause no harm to your ionizer. There are plugs on every port to ensure no leaks during transport. These plugs must be carefully removed. If you are not familiar with quick-connect fittings, please search our blog for a post showing you how to safely remove those plugs.

The Nexus seems like a great machine. I've only had it for about a week but I have tested the water and it is better than the water I was purchasing before."   Peter H.
"My mechanic was given a hydrogen water machine in lieu of payment from someone, and he said that his arthritis was just about gone! Well, I am a musician and load my equipment and play for hours holding a guitar and bass guitar, and of course I have back pain! After many many hours of searching online, I found the Nexus X-Blue. The video demonstration on your site showed me that this is what I have been looking for. I could never find one under $2000, and this one was! My friend helped install it next to my kitchen sink and it's beautiful! It was very easy! So modern looking! I have let people drink the water and I have been told that it tastes so smooth as if it's aerated! I can guzzle this water. I tested it today with the strips and solution it came with. Guess what? It's 9. My tap water was 6. Such a great company! I was sent an email right away to find out how I liked it and if I needed anything."   Cathryn V.

I daily drank 5 glasses a day 1 every approximately just under 5 hours apart 16 oz at a time. year after year, and I lost 75 pounds, with no exercise at all, (I am disabled) .

"I'm enjoying my alkaline water produced by my recently purchased x-blue water ionizer. Thank you very much."   Teresa B.
"I bought my nexus blue ionizer several years ago now, & never could have done it, without having your payment plan available to me. I'm literally, forever grateful! I survived a disease never seen before in usa, (though i know i am not the only one, & my suspicion is that as long as our tap water is essentially poisonous, & GMO products saturate our foods, cases like mine, will continue to manifest). Also, I don't think its a coincidence, that my recovery has continued. I think the way you strive to help make it possible for people to get these, is some of the worlds most important work! It cannot be underestimated! So i do feel such an immense gratitude for this company!"   A.S.
"Like I'm sure MANY others are, I too was skeptical about not only this ionizer, but investing money into one. I have to say....it's been almost a month, and my hubby and I have noticed many differences; my skin is clearer, he has more energy, and heartburn is GONE! This is def a great investment! I love the colors, the simplicity of the design, but also the fact you can get audible alerts. I will say we eventually muted the dern thing. I've also tested the quality with various methods to make sure we;re getting a quality product. Thanks to thorough research and hearing my mom say "You pay for what you get" I'm very pleased we decided to invest!"   Terri L.
"Fantastic piece of equipment does all it says and more I love it! Better then my 4 stage RO filter!"   Nicholas
"I had been getting Kangen water from a friend and absolutely loved it! But we cannot afford to buy a "Cadillac" unit. So, a bit of research brought me to the alkaline water plus website where I was able to make an informed decision to buy an X-Blue, which we could afford and still get quality water. I am pleasantly satisfied with our unit."   Mary H.
"I did some research on water ionizers and decided on the Nexus X blue. The price point is excellent and, so is the product. Its from a highly reputable company that not only talks the talk but, walks the walk! IT DOES THE JOB....PERIOD!"   Gary M.
"Alkaline Water Saving Lives Everyday!!! What a turn around in my health and in my life starting, 3 years ago, when I bought my X-Blue and started consuming alkaline water regularly, 5 times a day!!! Incredible healing water!!! Loving This Water Everyday!!!"   Kelly M.
"This X-Blue exceeds my expectation with the unbelievable low price and superb performance...Aside from showing on the colored screen what the machine is doing. It even announces it like washing, purified water, alkaline water etc. Excellent customer service."   Blandina A.
"I've been a type one diabetic for 13 years and not ONCE did a doctor talk to me about quality of water impacting how much insulin your body needed. From switching from a Brita filter for our tap water to the Nexus X Blue, I've been able to decrease my overall insulin intake by at least 20% most days while having increased my carb intake. Thank you for helping me gain better quality of health for life!"   Casey P.

"The X Blue is a great product, and working perfect. I checked my local water for hardness and found it was soft, so thanks for letting me know I needed the mineral cartridge because that brought my ph levels up to were they needed to be. Plus really good ORP levels. Thanks for doing all the leg work on testing so many ionizer's that are out there. Best decision I've made in awhile! I've already recommended a friend to buy one for his home."   Joseph T.

"The X-Blue is worth its weight in gold because of how much better I feel. Love this machine."    Terrie S.
"We have been using the Nexus X-Blue ionizer for about a week now. It has made a world of difference in our energy levels. Who could have thought in one week that we would notice more energy on a daily basis. The water is so much easier to drink than bottled water."    Mike T.

"So far, so wonderful. I am new to water ionizers. I bought the X-Blue machine because it was within budget, and it had most of the features that more expensive machines have. I really enjoy the water quality and the taste. I've noticed a difference in hydration, and with acid re-flux. I am a regular blood donor and my hemoglobin amazed me. I used to have 11.8, but on Saturday it was 14.9. I haven't changed anything in my lifestyle or diet for the past several weeks except drinking ionized water."    Enina V.
"WITH THE X-BLUE WATER IONIZER MY WHOLE LIFE HAS CHANGED. I just want to thank you very, very, very much from myself and my wife [married 54 years now]. Ever since I started using this alkaline water from my Nexus water machine four months ago my whole life has changed. My belly's a lot better now and I no longer have any type of gas and things like that. It's great. I love it very much."    Rich Riding
"Coming from the world of 'Kangen' water (which is no different than any other alkaline ionized water), I was skeptical about buying another machine brand after 12+ years with zero problems. But everything I watched and read on the Nexus made me feel it was worth the plunge, especially for the price. It was a great choice indeed. Unlike the outdated look of my old ionizer, the X-Blue looks very futuristic plus it's super easy to install and use. The warranty was also another factor in my decision making. When it comes to quality...I'm told Korea made products are very much in line with those made in Japan."   B.R.
"My Nexus machine gives great alkaline water."   Warnakulasurya T.
"I have been using the Nexus x Blue Water Ionizer for over a year and I love it. Easy to use and I enjoy having alkalinized water for drinking and cooking. And I am glad that I am not contributing to the overabundance of plastic bottle waste by buying bottled alkaline water."   Carolyn
"The Nexus x-blue is a fantastic little machine, super easy install. Purchased for my family's health and everyone says the taste is really good. Hopefully this will help clear up my dads psoriasis."   Drew M.
The x-blue is an amazing product! It works great for the low price and the water is indeed alkaline. I can feel the positive effects within my body for drinking it. I also use the level two acidic water to clean my face. I use the alkaline water to cook my rice & vegetables and they turn out wonderfully."   Tammie J.
"Love my Nexus alkaline lonizer, it's good water in helping me keep my ph up . Just purchased my second filter , it keeps the water balance. Thank you ."    Johnnie J.
"Love this."   Maya V.
"I was pleasantly surprised I didn't have to pay 1K+ to get decent water. This its excellent water!"   Candice
"Absolutely love this X-Blue machine!! It makes my water taste so much better. I have recommended it to all my friends and have been completely happy with my purchase."     Kali E.
