Duchess Berkefeld Gravity Water Filter System (Ultra Fluoride Filters)

The Duchess Berkefeld is the most compact system in the Berkefeld family, making it an excellent choice for individuals, couples, apartments, RVs, or smaller kitchens that want dependable gravity-fed water filtration in a space-saving design.

Despite its smaller size, the Duchess provides a steady supply of clean drinking water for everyday use. The system can provide as little as 1.5 gallons per day and up to 2.75 gallons per hour depending on how frequently it is filled, making it a practical solution for daily water consumption.

Each Duchess Berkefeld system includes two British Berkefeld Ultra Fluoride ceramic filters, which combine a micro-porous ceramic outer shell with activated carbon and specialized filtration media. This multi-stage filtration design helps reduce bacteria, chlorine, sediment, fluoride, arsenic, and heavy metals, while improving the taste and clarity of drinking water.

Constructed from highly polished 304 food-grade stainless steel, the Duchess has a clean and durable design that fits comfortably on most kitchen counters. When fully assembled, the system stands 18 inches tall with a 7.5-inch diameter, while the chambers nest together for easy storage or transport.
