Ian’s Weekly Walkabout and Talkabout. Filtering the _____ out of filter claims

This week I’m talking about filter performance claims.

It’s a big issue that just gets below the radar of most consumers.

If you’ve never sighted our ‘whole-of-life’ laboratory test results, click here.

How we calculate a ‘whole of life’ filter test.
Firstly we make a calculation on how many litres we expect the filter to process. In our case we based it ona  family of four drinking 2 litres per day every day. Multiply that out and we came up with the ‘target’ litre count.

Then we had to find a laboratory willing to run the UltraStream for the target litres. This costs a lot more because most tests are of a simple sample: a single test performed once.

In our case it was a local university. We still needed them to pass through a  ‘witches’ brew of chemicals to see how the filter reacts to them. To run it continually would require 25 200 litre drums of poisons, so we do the ‘witches’ brew at the beginning of the test and at the end, but we actually run water from the laboratory supply through the UltraStream to the target litre total.

This tells us how the UltraStream filter performs if poisons/contaminants are introduced at the beginning of filtration and at the end of filtration. Ultimately it’s the only honest way to prove a filter.

In the last half decade, the ’new’ toxin known as PFAS is in our sights. It’s in the public domain, having been hunted out of corporate secret cellars. And it’s one more growing concern with our drinking water.. but that’s not the only place you’ll find it.

Water Ionizer.. or Hydrogen tablet?

We were lucky enough to be right there with the first ever hydrogen tablets some five years ago. Now we’re still way out front with our high yield hydrogen tablets.
