UltraStream Water Filter

UltraSafe Drinking Water For The Whole Family

Naturally Filtered Water

We believe that access to clean, fresh water is fundamental to our health and wellbeing. Filtering our tap water helps to provide good quality drinking water.

Most water filters remove some harmful chemicals and (perhaps) bacteria, which if consumed can cause diseases and general ill-health.

There are many other benefits of filtered water, including better taste, more cost-effective and environmentally-friendly when compared to buying bottled water.

A Chlorine Water Filter

Most municipal water utility companies use chlorine to treat drinking water. It is inexpensive, easy to add, and highly effective at killing many of the bacteria found in water.

While it’s a good disinfectant, chlorine can make drinking water smell and taste unpleasant, and it can also react with some metals and organics to form hazardous compounds. (THM’s)

Today, many town supplies use the cheaper but more toxic chloramines to treat water. Most low-cost filters cannot remove this toxin.

How UltraStream removes more chlorine

We use the best carbon available in the world. Catalytic carbon filters more carcinogens, pesticides, chlorine, chloramines, and volatile organic compounds (VOCs) far more efficiently.


UltraStream Alkaline Water Filter 

A Fluoride Water Filter

Fluoride is very difficult to remove from water – far harder than chlorine or chloramines or even heavy metals!

There are only two recognized ways to remove fluoride; specialized filter media and Reverse Osmosis.

How UltraStream filters Fluoride:

The UltraStream uses a large adsorption layer of fluoride-specific media to remove fluoride.


A Heavy Metals Water Filter

Heavy Metals such as lead are toxic when ingested, and it’s essential to remove them from drinking water. Lead and other heavy metals commonly enter drinking water when it seeps into the water supply from old plumbing pipes or the solder used to join them together.

Lead contamination achieved notoriety in Flint Michigan, but there are at least 200 US cities with toxic levels of lead in their drinking water.

How UltraStream filters Heavy Metals:

UltraStream’s KDF media removes lead, mercury, cadmium, chromium, thallium, and much more.

A Microplastics Water Filter

Microplastics are very small pieces of plastic that pollute the environment. They exist in our air, on our soil and in our water.

Microplastics are any type of plastic fragment that is less than 5 mm in length according to the U.S. National Oceanic and Atmospheric Administration. They enter natural ecosystems from a variety of sources, including, but not limited to, cosmetics, clothing and industrial processes.

Latest reports indicate Americans are consuming the equivalent of a credit card of plastic daily in their water, food and air every year.

How UltraStream filters microplastics:

The UltraStream has 1-micron filter pads to remove microplastics.

Pathogens Removal

Drinking water with disease-causing bacteria, viruses, or parasites (collectively called pathogens) can make you sick. Bacteria are everywhere in our environment, including spring water, bore water, and rainwater. Some of these bacteria can be harmful to human health.

How the UltraSream filters Pathogens:

Cutting edge filtration technology removes submicron pathogens and inorganic contaminants through electro-adhesion and ion exchange. Proven in tests to remove up to 99.99% viruses, bacteria, and cysts exclusive to AlkaWay.

My Ultrastream water filter is an essential part of my life – I never want to be without the wonderfully healthy, pure, alkaline h20 it provides me! My recent purchase of a replacement cartridge is actually my 3rd one – with my everyday usage of this water filter system, I replace the cartridge every 12 -16 months to ensure it's working properly. It’s just a single person household use for me.

I love it! Water is an essential daily resource needed for life. Why not drink the best and purest water you can get. I highly recommend the Alkaway Ultrastream to everyone. I also purchased the extra fluoride filter. The water is beautiful, I cook with it, drink it cold & in cups of tea. Good stuff!
