The British Berkefeld water filter shares many characteristics with the Rolls Royce automobile. Both are old marques, both are made in Great Britain, and each, in it's respective field, represents the pinnacle of quality. The British Berkefeld SS-4 uses ceramic "Super Sterasyl" filters to reduce up to 99.99% of particulates, cysts, parasites and pathogenic bacteria including but not limited to E. Coli, Cryptosporidium, Giardia and Salmonella Typhi. These filters will reduce chlorine, rust, sediment and organic chemicals with nominal particulate filtration rating efficiencies of 99.99% filtration at 0.9 microns, 99.9% at 0.5 microns, and 98% at 0.2 microns.

The durable ceramic filters can be cleaned many times with a soft brush or Scotch Brite pad. Each element will filter up to 2000 gallons, depending on water turbidity. Filtration rate is 1 gallon per hour for the 4-filter unit and 1/2 gallon per hour for the 2-filter unit. These filters work by gravity, so electricity is not required. Easy to follow assembly and operating instructions are included. Housing is gleaming stainless steel. For durable, proven, foolproof delivery of pure water, British Berkefeld is the answer.
