Best Under-sink water filter: Water2 Filter, £129
Best Under-sink Water Filter
The Water2 capsule, born out of collaboration with University College London, offers a year-long lifespan and installs onto the cold tap pipe under your sink. The internal filter is sourced from coconut shells and uses a proprietary blend of activated carbon and silver ionisation to filter tap water to 0.1 microns – something Water2 says is 2,000 times more effective than the Brita Maztra Jug.
The packaging was all recyclable. Inside the box is a capsule and filter, a white adapter for converting 3/8" to 1/2" to fit all taps in Europe, two black washer circles for the input and output, a battery to power the smart capsule indicator and a how-to guide in English and Italian. This guide offers easy-to-follow pictures but very small written instructions. More useful was the series of step-by-step setup videos that you can access once the capsule arrives.
There wasn't a noticeable impact on water pressure after installation but it made a big different on taste and mouthfeel.
Pros:
Filters to 0.1 microns
Fits all European taps providing they're flexi pipes
Recyclable packaging
Made in a solar-powered facility in Italy
Star rating - 5/5
“UCL alumnus launches innovative water filter”
Water2 was set up by alumnus Charles Robinson (UCL Philosophy) in 2020 to address the issue of improving access to fresh drinking water for people all over the world.
Water2’s main product, the Pod, is an under-sink water filter that uses activated carbon and silver ionisation to filter tap water to up to 0.1 microns (where one micron is equal to a thousandth of a millimetre). Particles larger than this will not pass through into drinking water. The Pod therefore filters water over 1,000 times more finely than many typical household water jug cartridges.
Compared to commercial filter jugs that need a fresh cartridge every month or so, the Pod only requires one capsule a year.
Why should I filter my water? It’s simple.
We chlorinate our water across nearly every water system to disinfect and kill bacteria such as e.coli (definitely don’t want that) but that chlorine shouldn’t be there when we drink (not to mention the grim chemical smell).
The chemical smell of chlorine can be immediately worrying for drinkers and the effects of overexposure are equally scary; vomiting, diarrhoea and stomach issues.
Chlorine is an obvious issue smelt and tasted by millions. But the other dangers are more hidden. Microplastics are an emerging threat. Their presence has gone beyond the tap and they are now being found in human blood.
They’ve already been linked to immune system dysfunction, cytotoxicity and cancer. Lead piping is still present in an estimated 25% of homes, despite it being illegal. The dangers of lead include brain damage, kidney damage and nervous system damage.
UK water being ‘amazing’ is a myth. There are countless contaminants, pollutants and nasties swirling around in your water. This is just the surface.
