OVERVIEW

WaterChef® Premium Under-Sink Filter Cartridges

ENJOY SUPERIOR PERFORMANCE AND A 600 GALLON RATED CAPACITY!

WaterChef combines the effectiveness of solid carbon block filtration with a proprietary blend of additional filter media in its innovative Big Block™ Filtration Technology. This advanced system maximizes contaminant reduction, providing up to 600 GALLONS (2,271 L) of freshly filtered water with each cartridge!

This unique formula offers unparalleled reduction of a wide array of common tap water contaminants, including:

  • Lead
  • Mercury
  • Microplastics
  • Cysts (including Giardia and Cryptosporidium)
  • Chlorine
  • Chloramine
  • Microplastics
  • PFOA/PFOS
  • Chlorine By-Products (such as Trihalomethanes)
  • Synthetic Contaminants (such as Pesticides and Herbicides)
  • Industrial Contaminants (such as Volatile Organic Compounds (VOCs))
  • NSF/ANSI Standard 401 Emerging Contaminants (such as Pharmaceuticals and Detergents)
  • Petroleum Contaminants (such as Benzene and MTBE)

Furthermore, the UR85's distinctive media formulation preserves essential minerals like Calcium, Magnesium, and Potassium in the water. This ensures that the water not only tastes great but also remains naturally balanced and healthier, without the de-mineralization and "flat" taste often found in other water filtration methods such as reverse osmosis and distillation.

easy filter changes

With WaterChef, you can savor top-quality water at a fraction of the cost! Experience the added convenience of a 600 GALLON cartridge capacity—equivalent to over 4,500 plastic water bottles.

For most households, this means replacing just ONE filter cartridge per YEAR! Comparatively, pitcher, faucet, and refrigerator filters are less effective and require up to 25 replacements annually. Fewer cartridge changes not only save time but also reduce waste.

IAPMO Platinum Seal The water filtration industry is unfortunately rife with manufacturers and sellers making unverified and exaggerated performance claims. However, you can trust WaterChef. We have invested in independent NSF/ANSI testing and certification by one of the most reputable authorities in the industry, IAPMO Research and Testing.

The IAPMO Platinum Seal, awarded only to the most reliable and trusted producers of quality water treatment systems, requires the strictest testing and compliance standards. This prestigious certification is valued by consumers, manufacturers, retailers, and regulatory agencies worldwide. Independent NSF/ANSI Certification embodies the essence of trust.
