Sagan Life Filter Technology - How it Works
The patented filtration media technology used in all Sagan water purification products is based on electro-adsorption of contaminants, not mechanical filtration. The electro-positively charged media acts like a magnet attracting and retaining contaminants, as small as viruses, out of the water as they come in contact with the media.
The media itself is made of layers of non-woven, nano-alumina coated glass fibers containing powdered activated carbon (PAC) and antimicrobial protection (silver). The positively charged media field is sandwiched between layers of spunbond polyester, which provides strength to the pleated media.
The proprietary filter media offers exceptionally high flow rates and efficiency in removing contaminants. The media has been shown to remove viruses, bacteria, cysts, volatile organic compounds (VOCs), disinfection by-products, endotoxin, natural organic matter and other sub-micron particles.
