NanoFiber Filters


  • They are not a mechanical filter media that relies on pore size to remove contaminants
  • Removal of sub micron contaminants is achieved by electroadhesion and ion exchange
  • Filter is based on the mineral pseudoboehimite, AIO(OH)
  • Each gram of Alumina fiber has a surface area greater that 500 sq. meters
  • The active fibers are 2 nm in diameter and approximately 250 nm in length
  • The crystal structure of the mineral creates a natural electrokinetic potential of Al+++ on the surface of the fiber
  • It is not an electrostatic charge that can be dissipated by alcohol immersion
  • Charge potential maintains integrity between pH of 5.0 - 9.5 in polar liquids
  • The available hydroxyl group in each fiber will also exchange protons with many  electropositive colloids to retain them through a form of ion exchange
  • The Crystal structure allows for an extremely high surface area and a large number of active sites for sub-micron contamination removal
  • The pore size of the media is engineered such that the charge field covers the entire void of every pore
  • There are approximately 400 layers of these pores in the thickness of the media that contamination pass through during filtration, creating a tortuous path
  • The charge field removes the negatively charged sub-micron particles while the larger particles are captured with the fiber structure of the media
  • The Nano-fiber filter captures "small" particles not captured by conventional, mechanical filters
  • The  Nano-fiber filter captures organic/microbial macromolecules
  • Removes bacteria and viruses
  • Mean pore size of 1.25 microns 
  • Cartridge pressure drop <0.1 bar
  • Unique benefits: High flow rates, low pressure drop at Sub-micron retention
  • Each layer has Nanoalumina, powdered activated carbon, Antimicrobial silver and approximately 400 layers of charge fibers

Reduction levels:

  • 99.9999% virus reduction      
  • 99.9998% bacterial reduction
  • 99.99% cysts, guardia reduction
  • Reduces, fluoride, chlorine, lead, heavy metals, pesticides, pharmaceuticals, DNA, RNA, arsenic, chromium, endotoxins, mercury, and much more
  • Silver/Carbon infused, they are anti-microbial
  • 5 micron pre-filter outer wrap for longer field life

Advantages over RO Membrane which work on the basis of mechanical filtration and the need for high pressure and small pore size to remove Sub-micron particles.

The extremely small pore size of a membrane cause low flow rates. High water waste is also an issue with RO systems, as much as 5 gallons is needed to produce one gallon of water

Nano-fiber media has a much larger physical pore sizes which allows for higher flow rates, lower pressure drop, and can still remove Sub-micron particles due to the inherent charge field which extends across the entire void volume of the pores. There's no water loss, 100% of the water passes through filtration
