Duchess Berkefeld Gravity Water Filter System
The Duchess Berkefeld is the smallest 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 compact 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 genuine British Berkefeld Ultrasterasyl ceramic filters, which use a micro-porous ceramic outer shell combined with activated carbon filtration. This design helps reduce bacteria, sediment, chlorine, and other common contaminants 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.
If you are looking for a compact gravity water filtration system that delivers trusted ceramic filtration and great-tasting water without electricity or plumbing, the Duchess Berkefeld is a simple and reliable everyday solution.
