CuZn Pharmaceuticals and Cyst Water Filters
Removes Cysts and Drugs in Drinking Water

CuZn Absolute 1-micron Countertop and Under-Counter Filter Removes
Nearly All Cysts and Pharmaceutical Drugs from Water

Cysts

A Cyst is a closed pocket or pouch of tissue; a cyst can be filled with air, fluid, pus, or other material. Common water-borne microbiological cysts are Cryptosporidium or Giardia cysts.

CRYPTOSPORIDIUM
Cryptosporidium is a parasite that enters lakes and rivers through sewage and animal waste. It causes cryptosporidiosis, a mild gastrointestinal disease. However, the disease can be severe or fatal for people with severely weakened immune systems.

GIARDIA
Giardia lamblia is a parasite that enters lakes and rivers through sewage and animal waste. It causes gastrointestinal illness (e.g. diarrhea, vomiting, cramps). Giardia outbreaks can occur in communities where water supplies become contaminated with raw sewage. It can be contracted by drinking water from lakes or streams where water-dwelling animals such as beavers and muskrats, or where domestic animals such as sheep, have caused contamination.

Pharmaceutical Drugs

As recently reported in the news, analysis of tap water supplies in major metropolitan areas conducted by the Associated Press has revealed that the water supply in 24 major U.S. cities -- serving over 40 million people -- are contaminated with trace amounts of pharmaceuticals including antibiotics, anti-seizure medications, anti-inflammatory drugs, psychotropic drugs, pain medications and even caffeine. The upshot of the report is that tens of millions of Americans are unwittingly being subjected to a bizarre medical experiment with unpredictable results. No scientist can say for certain whether long-term exposure to micro doses of multiple pharmaceuticals is safe because such an experiment has never before been conducted on any population.

Three excellent methods for removing cysts and pharmaceutical drugs from drinking water is to super chlorinate the water, boil the water for one minute or use a one micron absolute acid wash coconut shell carbon filter. Some "1 micron" and most "nominal 1 micron" filters will not work against Cryptosporidium.The absolute 1 micron filter will more consistently remove Cryptosporidium than a nominal filter. Some nominal 1 micron filters will allow 20% to 30% of 1 micron particles (like Cryptosporidium) to pass through the carbon pores. The pore size of filter media is identified by the diameter of the particle that it can be expected to retain with a defined, high degree of efficiency. Pore sizes are usually stated in micrometer or microns for short (µm), which equals one millionth of a meter. Pore size ratings refer to the size of a specific particle or organism retained by the filter media to a specific degree of efficiency. Ratings can be stated as either nominal or absolute pore size.

Absolute - An absolute pore size rating specifies the pore size at which a challenge organism of a particular size will be retained with 100% efficiency under strictly defined test conditions. Among the conditions that must be specified are: test organism (or particle size), challenge pressure, concentration and detection method used to identify the contaminant. Absolute micro-filters are used for critical applications such as sterilizing and final filtration.

Nominal - A nominal pore size rating describes the ability of the filter media to retain the majority of particulate at (60 - 98%) the rated pore size. Process conditions such as operating pressure, concentration of contaminant, etc., have a significant effect on the retention efficiency of the filters.

NOTE: Flow capability usually drops off as the micron rating gets smaller, especially if the water has a lot of sediment, which well water often has. Unless you are sure that cysts or pharmaceutical drugs are a problem, you might be happier with the 5 micron countertop or under-counter water filters.

Single Cartridge Countertop 1-Micron Absolute Cyst/Drug Water Filter

The CuZn Refillable Countertop Cyst/Drug Water Filter system treats all incoming cold water that goes to the kitchen or bathroom sink. Turn on your cold water faucet for an uninterrupted supply of fresh, clear, filtered water. The CuZn Countertop can also filter hot water, provided it is flushed with cold water afterward to release the heat that would otherwise be trapped within the filter housing.
