Water Ionizers and reviews from Alkaline Water Plus Skip to main content


Ionia Water Ionizers

Ionia is the largest and most well-known manufacturer of water ionizers in Korea and the world. They have been leaders in water ionizer technology since 1982. Ionia has the largest R&D team of any other water ionizer manufacturer and they make several brands of water ionizers. You cannot find a better manufacturer of water ionizers than Ionia.

The four best brands of Ionia's water ionizers are: Jupiter, Smart, Nexus and the Ionia Super-S12 Water Ionizer. To learn more about the first three brands, you can find them each on their own pages for convenience and to avoid confusion, as to which filters to order.

No matter what Ionia water ionizer you choose, you can be assured that you have received the top water ionizer for that price range.

Installation of Ionia Water Ionizers

Ionia makes their water ionizers to be hooked up directly to your faucet with a faucet-diverter. These water ionizers all come with diverters. If you should want to hook your Ionia water ionizer directly to your plumbing you can do that, but we recommend you install an external shut-off if you do. This will help to ease up on the pressure inside the machine. Constant pressure may eventually develop a leak.

Ionia Certificates and Patents

Ionia holds more patents and certifications than any other water ionizer manufacturer. Here are some of them:



The limited lifetime warranty is described, below. Save your invoice for proof of your entitlement to repair or trade-in under this warranty. For any warranty service, you must have proof of purchase of your water ionizer from either Alkaline Water Plus or one of it's authorized dealers. Also, the warranty program does insist people at least buy replacement filters yearly. Make sure you do this. Lack of proper, minimum-yearly, filter replacement can hurt the internal parts of any water ionizer machine.

WARRANTY OVERVIEW: Any defect of a single part, which develops from spontaneous-malfunction within the first five years, is entitled to full warranty service, which means repaired free of charge for both part and labor. Spontaneous-malfunction means that the problem was not customer-error, source-water damage, or other situation that arose from the customer, shipping company, or environment, which resulted in the damage. It just happened, and there is no fault on the customer's part or the environment's part.

  • Labor: You are covered for your lifetime-labor charges and trade-in credits even after five years and even if the issue is due to user-error.
  • Parts: After five years you will be only charged what we are charged (bare minimum charges and sometimes no charges) for the parts.
  • Conditional-Parts: If parts are no longer available or your machine is not able to be repaired, or there are multiple parts that went out (making a repair impossible or impractical), or even if you just decide you want a new water ionizer, you will qualify for trade-in credits (see below). 

Definition of Customer Error: If you damaged the machine by customer error you will most likely be asked to pay for the cost of parts to fix it. Labor is always free of charge. The warranty is intended to cover spontaneous defects in the product only. The right to free warranty service is based on the proper use of the equipment and proper shipping. Customer error means: misuse, drops, rough handling, rough shipping, improper care, improper water source, commercial use, operating for over one month with an internal leak without sending for repair, infestation, collisions, fire, flooding, natural disaster or violating anything listed in the Notes & Cautions section, below. One of the most common errors is overusing the machine. You should never try to pour more than 5 gallons at a time without giving the machine a break, or it could burn up the SMPS. Burning up the SMPS with over-use is an example of user-error and may cost you $300 to repair.

In the event of customer error, we will still repair your water ionizer at a reasonable rate (no matter what the cause of the damage). We will do this forever if you want, as long as you are our customer. If we have to charge for parts, it will be the price we are charged, and will not be inflated.

Trade-In Credit: Trade-in credit is a unique feature of this warranty. You can use this even if your water ionizer isn't damaged. By "trade-in" is meant you are trading in your warranty (right to free repairs) for a new water ionizer. You don't have to ship us your old water ionizer though. This is a great deal, especially if your old water ionizer is still working! For instance, you may just want to upgrade to a newer model or another of the same water ionizer. We offer you a new water ionizer and will credit you 35% of the amount you paid for your ionizer toward the price of the new water ionizer. [Note: In cases where a water ionizer is already greatly marked down due to a sale, please check with us about this. It may not be possible to get full trade-in credit in this case, but we will honor it even then if at all possible.] All you have to give up is the right to warranty service on the older water ionizer when you use your trade-in credits. You keep your older water ionizer, or give it to a family member, and get an exceptional discount on a new water ionizer of your choice (as long as it's of equal to or greater retail value as the older water ionizer was when new). We offer this regardless of whether the machine is damaged or not...even if you caused the damage yourself. The newer model will of course come with its full, standard warranty.

We reserve the right to refuse to repair a water ionizer that is made too thoroughly damaged by customer-error (violations of our protocols), as described above. But even in that case you will be still credited with trade-in credits. You can use trade-in credits at any time.

Notes & Cautions -- Caring For Your Water Ionizer Properly:

  • If you have excess sodium, due to a water “softener”, or iron in your source water, you would need to filter them out as part of the expected proper care. Do not put salt in the mineral port of any water ionizer unless told by the manufacturer that this is authorized. Sodium and iron are both highly electrically conductive and could cause undue damage to your water ionizer over time.
  • Save yourself from accidental user-error and prevent trouble before it happens by knowing how to set up and care for your machine. Here are a couple of pages about that:
  • It is a condition of the warranty that you agree to replace the filter cartridge at least every twelve (12) months. We have to be able to find your filter purchases in our records. Using any filters other than those listed on this page will void your warranty. We do not accept filters purchased elsewhere.           
  • Ionizers should not be subject to continuous flow of ionized or filtered water all day long, unless the manufacturer says specifically that they are intended for commercial use (i.e., more than 5 gallons of pouring at any one time or more than 25 gallons per day). 
  • If you live in a hard water area, please note that cleaning scale from inside a water ionizer is not offered as a free service, however we will send you instructions of how to do this easily yourself. If you know your water is hard, we suggest you use the EOS (Elimination of Scaling) Device or the Ultra Spartan Ionizer Shield to protect your machine.
  • If your water-flow slows down, it could be caused by calcium build-up. Do not continue to use the water ionizer without doing the proper vinegar wash first. If that doesn't fix it, you should contact us for advice.
  • Under sink installation or any installation that keeps any water ionizer under constant pressure is not suggested by Alkaline Water Plus, unless the manufacturer specifically allows it (such as the AlkaViva brand). Leaking issues could develop over time. We cannot therefore repair leaks in your machine due to it being installed under constant pressure. A way to get around this is to install an external shut-off to turn off the water supply in-between uses. For leak-free undersink installation we only recommend AlkaViva water ionizers.
  • The best water outflow-rate for any water ionizer is between 1.5 and 2 liters per minute.
  • If you operate a water ionizer regularly with over 2 liters per minute of water coming into it, that would be a customer error. We suggest to install an external flow-control shut off, which will regulate this automatically for you, if you have trouble with this.
  • Proper care of the water ionizer is necessary and is your responsibility as the consumer. Don't operate the water ionizer in a barn, garage or other dusty/dirty or greasy location, or in a location where the temperature isn't regulated to a normal room temperature.
  • If a malfunction occurs, further operation without making the needed repairs could cause more damage. For instance operating the machine with an internal leak could cause electrical shorts, rusting of internal screws and other such damage. While the first damage may be covered by your warranty, the further damage incurred by continuing to use would be a customer error. 
  • Water ionizers aren't intended to be left unused for several months at a time. The best use of a water ionizer machine is to use it every day. If you are away for more than a couple of weeks, you should try to arrange for some water to be poured through it every week (or at least every month) to keep the water cell from drying out. If the machine is disconnected from a water supply the provided plugs must be kept in placed on every port and the filter (or a blank filter) should be placed in the filter port. This is to ensure the membranes in the water cell don't dry out.
  • Operating any water ionizer with a dried-out water-cell can cause the water cell to burst when you start it up again. If you think your water ionizer water cell may have dried out, contact us for detailed instructions on how to safely get it up and running again. 
  • Cost of shipping, both ways, is the responsibility of the customer for repairs. If you pay for a new water ionizer using trade-in-credits, though, the shipping cost is free. You can call or email us to arrange a repair shipping label to be sent to you at your expense. This way you can take advantage of our shipping discounts.

Note: Do not return your water ionizer for repair without pre-approval or without following our instructions for shipping. You must have our approval, and then follow our packing/shipping instructions precisely, to qualify for warranty service. 

Shipping: You will be shipped a water ionizer that is in good working condition. If your water ionizer arrives damaged, we will replace it without charging you shipping costs. But, you must notify us of the damage within 30 days.

After that, all shipping [both ways] for warranty fulfillment is the responsibility of the purchaser. You can call or email us to arrange a repair shipping label to be sent to you at your expense. This way you can take advantage of our shipping discounts. It is also your responsibility to save the plugs that come with your water ionizer. These must be used to ensure the safety of the machine (with no water leaks) during shipping. If you lost the plugs you will need to purchase new ones.

Notes: We reserve the option to repair or replace unit [with same or comparable unit].

Transfer of Ownership: You may transfer ownership, but you will need to contact Alkaline Water Plus in order to do so. We need to make sure all of our paperwork is in order prior to any warranty transfers. There is a $50.00 fee for warranty transfers.


Whether it is a return or repair the way you ship anything to Alkaline Water Plus is very important. Improper shipping has been known to cause damage to equipment in almost all cases. Therefore, 1) make sure to wait for our RMA (Return Materials Authorization) email before you ship (it will give you the proper way to safely ship), and 2) follow our instructions for safe shipping. The consequences of improper shipping are severe, and it would be considered a customer error.

How to Prepare a Super S12 for Shipping

It is urgent that you follow these instructions if you ever have to ship your Super S12 water ionizer. Damages caused by improper shipping are not covered by warranty.

  1. Turn off the water supply and open the flow-valve. Let the hoses drain. Blow through the spout to force water out of the filters as best as you can.
  2. Empty the saline port (bin), rinse it, and replace it properly.
  3. Close the filter "door" and make sure it's closed correctly (instructions, above).
  4. Once the filter door is shut properly, tape the right side of it shut to make sure the filter door doesn't open during shipping. There will be a very big mess and you may destroy the machine if you miss this point.


    5. Disconnect hoses and spout, and place the 4 plugs on/in place.  20210923-174129.jpg

    6. Cover the machine with the large plastic bag it came in.

    7. Place the top form-fitted foam on snuggly and wrap up the electric cord.

8. Turn the machine upside-down, sitting on the foam you just put on, and place the other foam snuggly on the bottom of the machine.
9. Slide the box down over the machine until it is flush with the counter. Make sure to tuck the cord in as you go. If the top foam gets loose (as you can see in the picture) try again till the box slides nicely and straight down over everything.
10. Now turn the machine upright and close up the box.
11. Never ship in the product box. For that would void your warranty. Instead, you need to put the box into a shipping box and use packing material as needed.
