Our UltraStream has been tested to 3500 litres by Griffith University laboratory for (among many other things) fluoride reduction.
We use an NSF approved non-eluting (it doesn’t leach into your water) US supplied Activated Alumina. It’s THE best we could find anywhere in the world, in line with all other filter media in our UltraStream.
Yet.. we still have some competitors trying to tell people that using activated alumina means you may get aluminium in your water, frightening them with fears of Alzheimers and anything else they can think of. So let’s give them the benefit of the doubt and assume they really don’t understand what alumina is.
The first thing we all learned in high school was the difference between an element (atom) and compound (molecule). But did we remember that well enough to remember it? Obviously not for some people.
Point #1. The difference between an atom and a molecule.
Salt is, as we know, safe to consume. But if we were told to consume chlorine we’d say no.
But.. chlorine is one of two parts of salt! Sodium is the other.
Sodium is an atom.
Chlorine is an atom.
Sodium chloride is a molecule, bound together ionically so it isn’t poisonous,
Aluminium is an atom.
Activated alumina is a molecule.
Point #2 What activated alumina actually is in nature
Now.. what if I told you we added ultrapure semiprecious gems rubies and sapphires to your UltraStream and used them to reduce fluoride? I’m guessing you’d be pretty impressed, right? Well.. that’s exactly what we are doing.
Look at this from Wikipedia.
Activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material; this material can have a surface area significantly over 200 square metres/g. The compound is used as a desiccant (to keep things dry by absorbing water from the air) and as a filter of fluoride, arsenic and selenium in drinking water. It is made of aluminium oxide (alumina; Al2O3), the same chemical substance as sapphire and ruby (but without the impurities that give those gems their color). It has a very high surface-area-to-weight ratio, due to the many “tunnel like” pores that it has.”
Go here to see how we use Activated Alumina in the UltraStream. And remember, we tested the UltraStream to the expected life of the filter. The tests are in our downloads section. There’s not another water ionizer in the world that has been tested to this degree. It’s obvious why: other methods of fluoride removal in water filters can be sold using an ‘as new’ laboratory test, without showing the rapid decrease in reduction each day you continue to use your filter.
If you’re looking at a water filter, watch for ‘Up To 99%” on the advertising and always ask for an independent LIFE OF FILTER test done in the country you are in, not Asia!
In every case I have seen of people attacking AA, their competing product hes been using a cheaper method. As in life, when you buy a water filter you ‘gets what you pays for’.
