Why We Choose Everpure Filtration Systems

Welcome to Everpure. Since 1933, we have provided quality Drinking Water Systems to households around the corner and around the world. Thousands of food service companies, including McDonald's, Burger King, 7-Eleven stores, Coca-Cola, Bertucci's and Outback Steak House, use Everpure systems for the best ingredient-quality water possible. Ships at sea, offshore platforms, major airlines and every surface ship in the U.S. Navy rely on Everpure systems to provide better tasting, healthier water. Even the President enjoys Everpure filtered water aboard Air Force One!

 

All Everpure filtration systems have been tested and Certified by NSF International to the highest standards. Everpure's proprietary precoat filters remove particles as small as onehalf micron in size, including harmful asbestos fibers and parasitic cysts such as Cryptosporidium and Giardia. NSF certifications are your assurance that Everpure systems will perform as advertised, and will never secretly fail or channel built-up contaminants back into the filtered water supply.

 

Water quality problems vary greatly from city to city and country to country around the world. Some communities experience minor difficulties with taste or odor. Others must deal with the presence of lead, volatile organic chemicals (VOCs), cysts, asbestos or trihalomethanes (THMs) in their water systems. Experienced Everpure chemists, biologists, engineers and laboratory technicians research complex water quality problems, then apply their expertise to develop cutting-edge solutions before our products are delivered and installed.

 

Everpure is recognized as the international model for this complex process. Our leadership is rooted in the company's broad-based knowledge of worldwide health, environmental and regulatory requirements, and in the diversity and technological advancement of our product line. Everpure's proprietary precoat filtration process has reigned as the unchallenged industry champion for over sixty years, but we have not rested on our laurels.

 

Everpure engineers and technicians continue to design and refine products to meet specific food service applications or to deal with special contamination problems, like the presence of cysts such as Cryptosporidium and Giardia. In addition to its precoat process, Everpure also uses granular activated carbon in filtration situations where water has a severe taste and odor problem or high levels of VOCs and THMs.

 

EVERPURE PRECOAT FILTERS REMOVE CYSTS

Several types of protozoan parasites infect people through ingestion of contaminated water containing their infectious forms, called "cysts" or "oocysts" (pronounced oh-ohsists). Cysts and oocysts are tiny packets of two to four immature forms contained in tough, leathery shells, which protect them from drying out. They form in the intestines of infected people or animals and pass out with feces. They are extremely common, being found in virtually all surface water sources used for public water supplies. Unfortunately, their shell also protects them from the action of the disinfectants used by waterworks to purify drinking water, and they are so small that many municipal filtration systems are unable to remove them reliably. Therefore, to be completely safe, contaminated water supplies must either be boiled for one minute or fine-filtered at the point of use. The most notorious protozoan parasites are: Cryptosporidium under the microscope

• Entamoeba histolytica, 10-20 micron cysts, cause of "amoebic dysentery"

• Giardia lamblia, 8-16 micron cysts, cause of "giardiasis"

• Cryptosporidium parvum, 4-7 micron oocysts, cause of "cryptosporidiosis"

 

These protozoan parasites are unusually efficient at causing infections--most bacteria and viruses require hundreds or thousands of them to evade the body's defenses, but consuming as few as one or two cysts or oocysts is likely to lead to illness. The illnesses they cause are generally just a few days of diarrhea, cramps, nausea, etc. for most healthy people, but individuals with AIDS or HIV, cancer patients on chemotherapy, organ transplant patients on immune system therapy, and many infants and the elderly are more susceptible to long-term, life-threatening disease. In some communities it is estimated that as much as 25% of the population may belong to endangered groups. Therefore, the efficiency of the fine-filtration used to remove them is of paramount importance.

 

There are no official point-of-use filtration standards, but public health officials have approved systems and products which demonstrate 3-log or 99.9% efficiency for filtration of either live cysts/oocysts or test particles with a size of 1 micron (micrometer, or "micron"). Also, NSF International, a third-party certifying agency, has produced a voluntary filtration performance standard (Standard 53: Drinking Water Treatment Units--Health Effects) which has been accepted by most public health of finials. NSF Std. 53 requires demonstrating at least 99.9% reduction of live cysts/oocysts, or alternately, at least 99.95% of test particles in the 3-4 micron size range. That is about half the size of Cryptosporidium oocysts, which are the smallest of these parasites.

 

Everpure precoat carbon filters are efficient fine-filters capable of removing these cysts/oocysts. They have be entested and Certified by NSF International to ANSI/NSF Standards 42 and 53 for more than 99.9% reduction of particles 0.5 to 1.0 micron in size in the general filtration test, and for more than 99.99% reduction of 3-4 micron particles in the Cyst Reduction test. Therefore, concerned individuals and businesses may use their water after filtration through these filters, even in the face of a "boil water order" or other notification of the presence of cysts/oocysts, but only if it is confirmed that the water is believed to be potable in all other respects
