    Superior Performance with Innovative Big Block™ Filtration Technology!

    Combining the power of solid carbon block filtration with a unique, proprietary blend of additional filter medias, WaterChef’s innovative Big Block™ Filtration technology maximizes contaminant reduction and delivers up to 1,000 GALLONS (3,785 L) of freshly filtered water with a single cartridge!

    This unique formula provides unsurpassed contaminant reduction for a broad range of common tap water contaminants including: Chlorine, Chloramine, Lead, Cysts (including Giardia and Cryptosporidium), Chlorine By-Products (such as Trihalomethanes), Synthetic Contaminants (such as Pesticides and Herbicides), Industrial Contaminants (such as Volatile Organic Compounds (VOCs)) and Petroleum Contaminants (such as Benzene and MTBE), while allowing beneficial minerals (such as Calcium, Magnesium and Potassium) to remain in the water. The result is great tasting water that is cleaner, healthier and naturally balanced (without the de-mineralization associated with other filtration technologies such as reverse osmosis and distillation).

    Say Goodbye to Small, Expensive and Less Effective Replacement Filter Cartridges.

    With WaterChef under-sink filtration you’ll enjoy premium water filtration at a fraction of the cost! You’ll also enjoy the convenience of a 1,000 GALLON rated cartridge capacity. For most households, that's just ONE filter cartridge per YEAR! (Compare that to the replacement cartridges for pitcher filters, faucet filters and refrigerator filters that are so small that they can require as many as 25 cartridges per year!) Plus, fewer cartridges to change means less waste too!

    Tested & Certified by NSF® International - Trusted Performance.
