Monderma Black Filters - For gravity fountains

Black Filters with Activated Carbon and Silver

The filters have been tested by NSF International (USA) according to the NSF/ANSI 42 standard. The test with Berkey red food coloring is remarkable: the red water comes out clear after passing through the filters. Black Filters is compatible with Berkey, British Berkefeld, Weeplow, Phoenix and ProOne gravity systems. The activated carbon stick is made of high-quality coconut shell activated carbon powder, combined with polymer materials, and processed by special processes. It is designed to effectively eliminate:

• Organic matter
• Residual chlorine
• Radioactive substances
• Pesticides and herbicides
• Volatile organic compounds (VOCs)
• Heavy metals (lead, mercury, cadmium)
• Unpleasant odors and taste
• Bacteria and microorganisms
• Suspended particles
• Industrial chemicals

The filter also has discoloration and odor removal effects. The carbon block is injected with silver, which helps prevent the growth of unnecessary pollutants.
