ANSI/NSF Standards for Drinking Water Treatment Units
Your Drinking Water Standards...
These standards represent only some of the many standards established by NSF for domestic drinking water systems.
Standard 42: Aesthetic Effects
This standard primarily deals with 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
Standard 53: Health Effects
This standard is concerned with contaminants that may pose a health risk such as:
Your Drinking Water Standards...
Volatile Organic Compounds (V.O.C.'s)
Pesticides and Herbicides
Volatile Organic Chemicals (V.O.C.'s)
A performance claim for V.O.C. reduction means the system reduces the concentration of all of the following contaminants. Some
of these chemicals can be tested individually for performance claims.
Ethylene Dibromide (EDB)
A performance claim for cysts indicates the system reduces the concentration of parasitic cysts by at least 99.95%. The cysts
included in this claim are Cryptosporidium, Giardia, Toxoplasma and Entamoeba.
A claim for turbidity reduction means the system removes fine particulate matter that makes water appear cloudy to a level below
the U.S. EPA Maximum Contaminant Level.
A performance claim for lead reduction demonstrates the system's ability to reduce the concentration of lead below the U.S. EPA
Maximum Contaminant Level.
California Department of Health Services Certification Program for Drinking Water
The California Department of Health Services certifies all residential water treatment devices sold in the state that make health
claims. Water filter systems that claim to reduce, filter or treat any chemical or compound that the state or federal government has
determined presents a health concern in drinking water must be certified to be sold in California. Examples of health benefit claims
include a device's ability to reduce or filter lead and other heavy metals, bacteria, cysts, nitrates, organic chemicals and pesticides.
Most testing for certification is done according to protocols that are part of the NSF International Standards. The testing establishes
that the water treatment device provides sufficient reduction of contaminants to warrant certification. Testing also determines that
the materials used to construct the system will not contribute harmful contaminants to the treated water. The manufacturer must
comply with product labeling and consumer information requirements before a device can be certified. A product data sheet is
provided for each product and includes:

Trivalent Chromium Radium 226/228
4. No longer a primary drinking water standard (MCL) but does appear on some certificates
The contaminants that are listed above are considered toxins and are harmful to our body. Once ingested continuously into the body by drinking unfiltered water,
the body cells and its organs will be affected and the immune system deteriorates eventually causing diseases.
The removal of these toxins is possible thru ganotherapy or the red mushroom therapy. To learn about the ganotherapy and how it works, just click this link: The Ganotherapy page
