The term water polishing can refer to any process that removes small (usually microscopic) particulate material, or removes very low concentrations of dissolved material from water. As with all filters, follow the manufacturer’s instructions for filter use and replacement. įilters that use reverse osmosis, those labeled as “absolute one micron filters,” or those labeled as certified by an American National Standards Institute (ANSI)- accredited organization to American National Standard Institute/National Science Foundation Standard 53 for “Cyst Removal” provide the greatest assurance of removing Cryptosporidium. The Water Quality Association is a trade organization that tests water treatment equipment, and awards its Gold Seal to systems that meet or exceed ANSI/NSF standards for contaminant reduction performance, structural integrity, and materials safety. Elken Water Filter Installation Water Quality Association Underwriters Laboratories, Inc., is an independent, accredited testing and certification organization that certifies home water treatment units which meet or exceed EPA and American National Standard Institute/National Science Foundation drinking water standards of contaminant reduction, aesthetic concerns, structural integrity, and materials safety. One goal of this not for profit organization is to provide assurance to consumers that the water treatment devices they are purchasing meet the design, material, and performance requirements of national standards.
The NSF's water treatment Device Certification Program requires extensive product testing and unannounced audits of production facilities. NSF International as it is now known started out as the National Sanitation Foundation in 1944 at the University of Michigan School of Public Health. Certification from these organizations will specify one or both of these specific standards. American National Standard Institute/National Science Foundation standards are issued in two different sets, one for health concerns (such as removal of specific contaminants (Standard 53, Health Effects) and one for aesthetic concerns (Aesthetic Effects, such as improving taste or appearance of water). Each certifies that home water treatment units meet or exceed National Standard Institute/National Science Foundation and Environmental Protection Agency drinking water standards.

Each American National Standards Institute/National Science Foundation standard requires verification of contaminant reduction performance claims, an evaluation of the unit, including itsmaterials and structural integrity, and a review of the product labels and sales literature. Three organizations are accredited by the American National Standards Institute, and each one of them certified products using American National Standard Institute/National Science Foundation standards.

Certification in the United States How To Service Elken Water Filter These water filters should not be confused with devices or tablets that disinfect water which remove or kill viruses such as hepatitis A and rotavirus. Filters may have fine meshes that must be replaced or cleaned, and ceramic water filters must have their outside abraded when they have become clogged with impurities. These filters work to remove bacteria, protozoa and microbial cysts that can cause disease. Dirty water is pumped via a screen-filtered flexible silicon tube through a specialized filter, ending up in a container.

These filters are usually small, portable and lightweight (1-2 pounds/0.5-1.0 kg or less), and usually filter water by working a mechanical hand pump, although some use a siphon drip system to force water through while others are built into water bottles. Water filters are used by hikers, aid organizations during humanitarian emergencies, and the military.
