NSF minimum percent reduction requirement. Acceptance level for this substance is based on percent
reduction, rather than maximum effluent concentration.
System tested and certified by NSF International against NSF/ANSI Standard
42 for the reduction of chlorine taste and odor and particulate reduction, and
NSF/ANSI Standard 53 for the reduction of benzene, cyst, lead and mercury.
General Information
This system has been tested according to NSF/ANSI 42 and 53 for reduction of substances listed above. The concen-
tration of the indicated substances in water entering the system was reduced to a concentration less than or equal to the
permissible limit for water leaving the system, as specified in NSF/ANSI 42 and 53. The testing was performed using
spiked tap water at a flow rate of 1.85 gallons per minute (7.0 L/min.), pH of 7.5 ± 0.5, pressure of 60 psig, and tempera-
ture of 68 ± 5°F.

Maintenance
Filter cartridges should be replaced every 2000 gallons or six months, whichever comes first. For replacement ele-
ments, call 1-800-986-3223 or contact your nearest Lowe’s store. Replacement filter prices will vary. Estimated cost of
replacement filter cartridge WHAFFS ranges from $70 to $100.
Model WHAFFS Kitchen & Bath Water Filtration System
IMPORTANT NOTICE: Read this performance data and compare the capabilities of this unit with your actual water
treatment needs. It is recommended that, before purchasing a water treatment unit, you have your water supply tested to
determine your actual water treatment needs. This filter system is designed to be used for the reduction of the perform-
ance claims listed below. Do not use where water is microbiologically unsafe or of unknown quality, without adequate
disinfection before or after the system. Systems certified for cyst reduction may be used on disinfected water that may
contain filterable cysts. While testing was performed under standard laboratory conditions, actual performance of this
system may vary based on local water conditions. Some or all of the contaminants reduced by this unit may not be in
your water supply. See elsewhere in this owner’s manual for further instructions on filter cartridge replacement, system
installation, operating procedures, and warranty. The maintenance instructions must be followed for the product to per-
form as indicated below.
