Do you live near Antwerp?
Your tap water contains PFAS.
In Zwijndrecht, Burcht, Beveren and across much of the Antwerp region, PFAS contamination has been confirmed — the legacy of decades of PFOS emissions from the 3M chemical plant in Zwijndrecht. Blood tests on local children returned PFAS levels above health-protective thresholds.

Flemish authorities have been documenting PFAS contamination around the 3M Zwijndrecht plant since 2021. Residents were officially advised not to drink groundwater from private wells and not to consume home-grown produce within the affected radius. Official Flemish government page →
The Solution: ETH Zurich BluAct Technology
At ETH Zurich, Prof. Raffaele Mezzenga developed a filtration technology based on whey-protein amyloid fibrils that selectively bind PFAS molecules — including hard-to-remove short-chain variants (PFBS, PFHxA, GenX). The technology was published in Nature Food and is exclusively licensed worldwide to Mam Nature Swiss.
The Essential Plus installs on your main water line and immediately protects every tap in the house — kitchen, shower, sinks, washing machine. Beneficial minerals are preserved.

Frequently Asked Questions
Does my tap water in Antwerp contain PFAS?
The Flemish Environment Agency (VMM) and the Agency for Care and Health confirmed elevated PFAS levels in groundwater, soil and local food around the 3M plant in Zwijndrecht. Blood tests on children in Zwijndrecht and Burcht showed PFAS concentrations above health-protective thresholds.
How much PFAS does the system remove?
The BluAct technology developed at ETH Zurich, based on whey-protein amyloid fibrils, removes up to 99.98% of PFAS compounds — including short-chain variants (PFBS, PFHxA, PFBA, GenX) that activated carbon filters often fail to retain.
Is installation complicated?
The Essential Plus is installed on your main water line and immediately protects every tap in the house. A licensed plumber typically completes the installation in 2–3 hours.
How long does the cartridge last?
One cartridge lasts approximately 12 months for an average family of four. Replacement cartridges cost €280. Compared to roughly €1,110/year for bottled water, you still save over €800/year.
What if I am not satisfied?
30-day return policy from delivery. You also receive a 10-year warranty on the housing and all non-wearing components.
