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 2.1 gallons per day (8 glasses / 65 fluid oz 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.

Up to 95% of Fluoride can be removed when the UltraStream is installed with an additional Fluoride Pre-filter.

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 0.26 GPM 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 the only regulated water in the US and is 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.
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.

Those who utilize well water should also expect great performance. Very often, well water starts a bit above 7.0 and this can also translate to higher pH outputs from the UltraStream as well. A sediment pre-filter will likely be required for well water.

  • 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 75 cents/gallon for the first year and then down to 31 cents/gallon on your 12 month filter change (benchtop version).

  • It 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 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 undersink without our special vented faucet! Voids any 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 Liters) 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 warranty for the UltraStream is 3 years (Conditions Apply) for parts and labour under normal use. The warranty does NOT cover filters as there are too many variables in the source water.

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)


Yes, the UltraStream is Vegan, the Fluoride reduction media in the UltraStream is Not bone char.
