U.S. EPA Maximum Contaminant Level * No Maximum Contaminant Level established ¹ NSF Test requirement of at least 50,000 3-4 micron particles per mililiter. The 3-4 micron size particle is a surrogate particle for Cryptosporidium and Giardia cysts ² U.S. EPA Action Level for Lead 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.
