NSF/ANSI Standard 42: Aesthetic Effects
Units are evaluated for material safety, structural integrity and accurate product literature. This standard primarily deals with Particulate and Chlorine removal, appearance and Taste and Odor claims.
A chlorine reduction claim means the system reduces the concentration of chlorine in the water. This category is broken down into classes that represent a certain level of Chlorine removal.
Class I - 75% or greater Chlorine reduction
Class II - 50% - 74% Chlorine reduction
Class III - 25% - 49% Chlorine reduction
A performance claim for Particulate removal means the system removes particles of a certain size based on the following classes:
Class I - Reduces 85% of particles 0.5 to < 1 microns in size
Class II - Reduces 85% of particles 1 to < 5 microns in size
Class III - Reduces 85% of particles 5 to < 15 microns in size
Class IV - Reduces 85% of particles 15 to < 30 microns in size
Class V - Reduces 85% of particles 30 to < 50 microns in size
Class VI - Reduces 85% of particles equal to or greater than 50 microns in size
