Higher Efficiency3

  1. 1

    All comparative figures reference conventional activated carbon block filters, widely used in home water filtration.

  2. 2

    Surface area is the total internal area of the filtration media available to capture contaminants. More surface area means more adsorption sites, the microscopic points where contaminants bind to the carbon as water passes through.

  3. 3

    Effective capacity measures how much water a filter can treat while maintaining strong contaminant reduction. Nanofiber+™ combines faster, more efficient filtration with greater resistance to clogging, helping sustain performance over more litres of water.

Your Water’s Journey to Your Home

On its way to your home, water travels through kilometres of aging pipes that can leach metals like lead and copper. Along the way, the chlorine used to treat it reacts with organic matter, forming byproducts like chloroform.

    Nanofiber+™ has demonstrated heavy metal reduction at typical municipal water concentrations. With the exception of lead, it is not rated for heavy metal reduction at the higher concentrations used in laboratory challenge testing. Please consult our performance data sheets for contaminant-specific results.

Minerals Preserved

Unlike reverse osmosis, Nanofiber+™ reduces heavy metals while preserving naturally occurring minerals that support bodily function, energy production and cellular hydration. These can include:

  • Sodium
  • Magnesium
  • Selenium
  • Calcium
  • Zinc
  • Manganese
  • Potassium
