Terms & Definitions

PFAS: Per- and Polyfluoroalkyl Substances (PFAS), are a group of man-made chemicals that includes PFOA, PFOS, GenX, and many other chemicals. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Both chemicals are very persistent in the environment and in the human body – meaning they don’t break down and they can accumulate over time.

Select Units w/ Model HFC-1000 cartridge, including single, dual, reverse osmosis, & purification systems that use this cartridge!

Methyl tertiary butyl ether (MTBE): Gasoline additive found to be leaking into ground water. Taste and odor primary issue. Use the HFC-1000 Drinking Water System for reduction.

Volatile Organic Chemicals (VOC’s): They include gasoline, solvents, industrial and household cleaners, pesticides, and other chemicals that can leach into our water supply. Use the HFC-1000.

Disinfection by Products (DBP’s): When aesthetic chlorine or aesthetic chloramines are added as a disinfectant in water other chemicals are produced as a byproduct. They include Trihalomethanes (THM’s) and VOC’s. Use the HFC-1000.

Lead: A heavy metal which causes mental retardation and birth defects. Introduced from lead based plumbing and service lines. All of our filtration products reduce this item.

Fluoride: An additive for reducing cavities in children and bone loss in adults. Many cities add this to their water supplies. Our filtration products leave in this additive.

Cysts: Such as Giardia and Cryptosporidium are parasites that develops a hard protective shell when it leaves its host and can cause intestinal illness, including, cramps, vomiting, and diarrhea. Found in 97% of all surface water supplies. All of our filtration products reduce these cysts. These cysts are very resistant to chlorination.

Bacteria and Bio Film: All water supplies contain bacteria that can cause a short cartridge life due to a build up of a bio film on the surface of the filtration system. The HFC-1000 & SF-1000 have silver zeolite technology blended through the cartridge to protect the filter. Silver Zeolite Ions are slowly released during the life of the cartridge and are NSF/EPA/FDA approved for use in potable water systems.

Micron: A unit of measurement equal to one millionth of a meter, 1/25,000 of an inch.

Sub Micron Filtration: A fine filter used to reduce particles less than one micron in size.
