"Appreciably better water quality"
After testing the WaterOne for a number of week, the water tasted noticeably fresher.

Iain and his family wanted to know if they could be drinking better water.
Despite being connected to the Thames mains water supply, considered to be one of the best in the world, Iain and his family wanted to know what was really in their tap water.
In this case study, we explore the concerns of drinking water quality, in a city property, and show the contaminants removed by the IF WaterOne purifier over a number of weeks.
The problem
Our client was concerned about...
Modern Contaminants
"We're hearing more and more about Forever chemicals, Micro plastics and hormones in the water, but what does it mean for our health?
There is still little known about the long term effects of modern contaminants like Micro Plastics and Forever Chemicals on our bodies, but there is growing evidence of potential risks.
What we did
IF installed a WaterOne to see the effects of Vapour Compression Distillation on London Water.
We ran the device for two weeks, producing around 10-20 Litres a day as larger volumes were not needed at the time.
The goal was to prove premium water can come from taps in some of the largest infrastructure stressed cities in the world.
Specialist lab assessments
We took full suite samples straight from the tap and directly from the WaterOne testing over 40 contaminants commonly found in drinking water.
In this trial we were not able to test for Modern Contaminants like MicroPlastics, Hormones and PFAS, because utilities companies themselves do not test for these contaminants, and we were using their test labs.
Taste Tests
"It tastes noticeably fresher"
We conducted blind taste tests of the WaterOne water and their filtered tap water.
Overwhelmingly the results showed that the WaterOne water tasted fresher.
The explanation for this is that the WaterOne takes all of the additional chlorine, fluoride and other elements of mains water out, leaving only fresh H2O.
Why the WaterOne system works
The vapour distillation process developed by IF involves converting water into vapour, then condensing it to produce purified water.
This method has the ability to consistently produce high-purity water, regardless of the source. It consistently removes bacteria and viruses, lead, nitrate, arsenic, and per- and polyfluoroalkyl substances (PFAS), and other contaminants like copper, chlorine, fluoride, pesticides and pharmaceuticals.
Compact home version coming soon!
"There were a number of device and usability improvements that we've taken from the install that we are building into our future product versions." Chris Chief Design Engineer
We worked with Iain and his family to build a design specification for a city home version of the larger technology that we aim to bring to market in 2026.
