The Puure® Hydro 2.0 under-sink cartridge uses an advanced multi-barrier filtration system with 6 engineered layers and 0.1 micron precision — 1,000x finer than a standard filter jug.
It reduces over 70 contaminants including chlorine, PFAS, microplastics, pesticides, heavy metals, residual pharmaceuticals, and excess fluoride — while preserving essential minerals like calcium, magnesium and potassium.
✔ NSF-42/53 certified components
✔ Independently tested by accredited laboratories
✔ Each cartridge lasts ~6 months (~5,000 litres)
It takes about 2 minutes, no tools needed.
Turn off the cold water valve under the sink, unscrew the old cartridge from the housing, screw in the new one, turn the water back on and let it run for 30 seconds. That's it.
Step-by-step instructions included with every cartridge.
This cartridge is designed exclusively for the Puure® Hydro 2.0 Under-Sink System (Classic and Inox models). It is not compatible with the Puure® 3.0 tap-mounted system — those use a different cartridge.

What's inside our cartridges?
Nature filters water through layers. So do we
6 specialised filtration stages — 0.1 micron precision
Puure® cartridge components are tested and certified by NSF International against NSF/ANSI Standard 42 for material safety. The Puure® Hydro 2.0 cartridge is specifically formulated for the contaminants commonly found in European tap water.
Stage 1
Non-Woven Fiber
Blocks rust, sand and sediment at 0.1 micron — 1,000 times finer than a standard filter jug.
Stage 2
Coconut Shell Carbon
Captures chlorine, pesticides and organic chemicals. No more swimming pool taste or odour.
Stage 3
KDF Media
Traps lead and heavy metals from ageing pipes. Inhibits bacterial growth inside the cartridge.
Stage 4
PFAS Media
Binds forever chemicals on contact — the contaminants most filters can't even touch.
Stage 5
Heavy Metal Media
A second dedicated layer for lead and heavy metals. Double protection for stronger results over time.
Stage 6
Fluoride Media
Reduces fluoride without stripping the good minerals. Clean water that still tastes like water.
