Replacement filter cartridges for the Tappwater EcoPro SMR tap water filter. Six-stage nanofiltration removes 93% of PFAS, 98% of chlorine, over 99% of microplastics and 70% of fluoride, and reduces limescale build-up by up to 80%. The sixth stage, Swedish Mineral Rock™, adds calcium, magnesium and potassium back into your filtered water. Each cartridge lasts 3 months or 1,200 litres, whichever comes first, and twists into place in seconds with no tools. Fits the EcoPro SMR filter housing.
