3Turbidity is measured in Nephelometric Turbidity Units (NTU's). It is calculated by measuring the dispersion of a light beam passed through a sample of water.Fine particles, silt, and suspended matter will cause a light beam passing through the water to be scattered. The measurement of NTU does not give the sizes of the particles, nor does it indicate the amount of particles present.

  • 1V.O.C.'s tested by Chloroform surrogate as specified in NSF standard53. Influent levels, effluent levels and reduction percentages are based on the actual reduction of the chloroform surrogate of .99.8% (at 200% of capacity).

    All V.O.C. testing was performed using chlorinated tap water with a TDS (total dissolved solids) level of 300 ppm and a turbidity content of .14 NTU instead of de-ionized water in order to demonstrate the filters ability to reduce contaminants under real life conditions. Most water treatment device evaluations are performed using de-ionized water which is a considerably less challenging test method.

    • Warning: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. Systems certified for cyst reduction may be used on waters that may contain filterable cysts.

    Note: Substances reduced are not necessarily in your water. Filter must be maintained according to manufacturer's instructions, including replacement of filter cartridges.

     

    * The AQ-4000 Water Enhancement System was evaluated to a test capacity of 1000 gallons, 200% of the  

       rated capacity of 500 gallons, to allow for a considerable safety margin. The filter cartridge should be   

       replaced every 12 months to ensure peak performance. (Base on per gallon cost, filter replacement is lower  

       than any other brand in the markets today.)
