UltraStream: far more than just another water filter

The UltraStream:

Water Ionizer

A water ionizer enhances the water’s ability to donate usable energy to you, the drinker, in the form of antioxidant power.

This ability is measured in Oxidation or Reduction Potential (ORP).

The UltraStream is natural, non-electric water ionizer. Its unique O-Dobi media delivers consistently high negative ORP levels and donates infused Hydrogen.

That’s why you’ll find it so easy to drink and you may begin to see changes in your daily energy levels.

The UltraStream:

Hydrogen Water System

At AlkaWay, we pioneered the output of molecular hydrogen by the UltraStream Water Filter.

UltraStream infuses molecular hydrogen (H2) into your purified, alkaline drinking water.

There are over 300+ published studies and 1000 scientific articles, on the health benefits of molecular hydrogen (H2). Hydrogen is fast becoming the secret ingredient that we predict may become essential in your daily health regime. UltraStream water is an easy way to give your body increased hydrogen.

Studies point to the possible beneficial effects of hydrogen on inflammation, allergies, cell signaling, free radicals and more. View Molecular Hydrogen Institute website Studies page…

The UltraStream:

Natural Water Alkalizer

A natural water alkalizer infuses water with beneficial alkaline minerals. The added alkaline minerals are measured in pH. UltraStream consistently increases your water pH to 8.0 – 9.0. Drinking alkaline water is a simple way that you can decrease the effects of our generally acidic diet and lifestyle. 

UltraStream infuses your drinking water with natural magnesium and calcium in every glass.

The final combination of media layers in the UltraStream softens and stabilizes the water, producing a smooth blend of balanced, hydrating water with a taste that you will love. You will never go back to tap water after you have tasted UltraStream water. 

The UltraStream:

High-Performance Water

Three synergistic methods work to improve and boost the health benefits of UltraStream water.

  • Semiprecious Tourmaline to soften and impart far infrared energy,
  • Neodymium magnet to stabilize the changes the UltraStream makes,
  • Natural quartz crystal to give the mountain spring taste our users can’t get enough of.

UltraStream water is not just filtered water. It’s enhanced, supercharged and energized water. 12,000+ customers love it and keep drinking their UltraStream water every day.

The UltraStream:

Virus Guardian

Traditionally the only way to remove viruses, bacteria and cysts for contaminant-laden water to pass through a very fine filtration (under 0.01 microns), the problem is these filters can become get clogged up easily or they remove the good alkaline minerals as well.

Virus Guardian (TM) doesn’t rely on particle size instead by creating a nanomesh of glass fibres coated with a charged mineral, this traps contaminants using electro-adhesion and ion exchange. There is no technology on the market that filters water like Virus Guardian.

Frequently Asked Questions

An UltraStream filter will last 12 months – depending, as always, on source water conditions and use. Our 12 month recommendation is based on a family of 4, who use about 8 litres per day (8 glasses / 2l each) for drinking and cooking.

If you use less, your filter may last longer. More – and you’ll need to replace sooner.

Filter life always depends on the quality of the input water. The more unwanted stuff in the water, the harder the UltraStream has to work. For the vast majority of users, 12 months of protection and performance is no problem.

When the filter is replaced (a simple 3-minute job) your UltraStream returns to full filtration, pH, hydrogen and antioxidant power.

Yes. Through lengthy research and development, the UltraStream uses the world’s best-activated alumina media, removing 78% of Fluoride throughout the life of the filter. Review or download our lab test results.

All of the attributes of UltraStream water can be controlled by flow rate. The faster the water flows through, the less hydrogen potent it is. We recommend a flow rate of around 1l/minute for the best performance. You can easily adjust the flow of the UltraStream by adjusting a small tap underneath the base of the UltraStream.  You can then just turn on the kitchen tap and the UltraStream regulates the flow.

Yes, the UltraStream can be connected in series with a reverse osmosis (RO) system. It will add powerful alkalizing and ionizing abilities to your acidic, mineral-depleting RO water.

You could also remove the RO system completely and replace it with the UltraStream.

Yes, unlike electric water ionizers, the UltraStream will also work well with a water softener.

Softened water isn’t something you want to drink or cook with, so the UltraStream is a great solution for consumption when you need to maintain soft water for appliance life and showering.

Our independent laboratory tests used a water sample that was a ‘witches brew’ of pesticides, volatile organics, fluoride, chlorine, heavy metals, and minerals. The UltraStream changed an input pH of 7 to an output pH 9 in these tests. We’ve pushed the lab much farther than the normal lab tests by asking for performance statistics beyond the normal lifespan of the filter. Most water filter tests are taken from the first water out of the filter. Most do not test for possible reduction in performance as the filter is continued in service.

UltraStream’s pH performance is directly related to the input water. Tap water is generally around pH 7.0 for most homes. The UltraStream performs wonderfully in this environment and will consistently produce water ranging from pH 8.0 – 9.0. Most commonly, the water starts at pH 9.0 at installation, and by the time the filter needs to be replaced, it measures closer to pH 8.0. The bottom line: more acidic input water will have a lower pH, more alkaline input water will have a higher pH but both may be adjusted using the flow control at the bottom of the UltraStream.

There are a couple of other advantages as well. In hard water with excessive levels of alkaline minerals (like an overabundance of calcium), the UltraStream uses a special patented media that alters the form of the calcium and prevents it from clogging the filter. It also re-infuses input water with healthier levels and proportions of alkaline minerals, as well as ionizing the water.

For EU conditions we have added a water softener tube magnet to the UltraStream inlet line. This converts calcium to water soluble aragonite. 

We’ve used our two decades of water filter experience to ensure this lasts the life of the filter, so you have excellent purity and performance from start to finish.

  • It helps people feel better, perform better and enjoy a healthier life.

  • It is easy to install, operate and replace the filter.

  • It is affordable, benchtop costing 22c/l for the first year and then down to 8.6c/l on your 12 month filter change (benchtop version).

  • Hydrogen is a selective antioxidant
  • It targets and neutralizes the harmful, cytotoxic free radicals, such as hydroxyl radicals.
  • Scientific studies have concluded that Hydrogen may help and prevent a range of diseases including cancer, diabetes, cardiovascular, arthritis, gout, and other inflammatory-related degenerative diseases.

Heavy metals including mercury, lead, aluminum and copper, as well as bacteria, pesticides, algae and fungi. For more details, Review or download laboratory test results.

There are 2 ways to install the UltraStream. 
1. Benchtop – For this connection to work, the faucet has to be “normal”. Normal means the tap doesn’t convert to a shower spray, pull out or have a non-standard head. You’ll utilize a diverter valve to control the water flow. When the slider of the diverter valve is pushed one way, it will flow from the tap as normal. When you push it the other way, the water will be sent to the UltraStream.

2. Undersink – For those who either have an upgraded faucet or who just don’t want the attention-grabbing UltraStream on the counter, we have an undersink kit option that includes a separate dedicated vented faucet with all the connecting pieces. Installation doesn’t require a plumber, but if you’d feel more comfortable using one, go ahead. We have sourced the specially designed vented faucet from the best water filter engineer in the US, so there’s no need to worry about lead. Please note that we cannot be responsible for the efficacy of your undersink installation.

Undersink Installation Video

IMPORTANT: Do not try to install the UltraStream without our special vented faucet! To do so voids any guarantee/warranty. 

The only consideration is for those taking pharmaceutical medicine or suffering from kidney disease. We recommend you consult with your doctor.

UltraStream water may be delivered to the cells more efficiently than tap or bottled, so we recommend not taking any medications with it. We suggest you stop drinking 30 minutes prior to taking the medication and then waiting until at least 30 minutes after.
We have no evidence of adverse results, but give this advice for legal purposes only.

Unlike electric water ionizers, the UltraStream’s filter cartridge actually contains the media that ionizes, alkalizes and infuses the water with molecular hydrogen. So when you change a filter, you get the brand new version, which will incorporate any updated technology we have implemented. That’s why we call it an ‘eternal’ system.

This depends on a number of variables. As a general guide for medium weight people is to drink about 1/3 of your body weight in ounces a day. So if you weigh 150 lbs (68 kgs), you should drink roughly 50 fluid oz (1.47 Litres) of water. If you work out, if it’s hot and you’re sweating more, if you fly, if you have a soda/coffee/tea, then you can choose to drink more. All of those things speed up the elimination of water and therefore, we need more.

The magnesium reacts with the water and produces magnesium hydroxide and hydrogen gas.

Mg + 2H2O → Mg(OH)2 + 2H → Mg(OH)2 + H2

Mg = Magnesium Metal H2O = Water
Mg(OH)2 = Magnesium Hydroxide H = Atomic Hydrogen (Active Hydrogen)
H2 = Molecular Hydrogen (Hydrogen Gas)
