A micron , also called micrometer, is a unit of measurement.

1 micron = 1/1000 mm (1/25,000th of an inch) is denoted by the letter µ.

Average human hair is about 75 micron in diameter and coarse dirt is about 40 micron . In filter cartridges, a micron rating refers to the smallest particle size in micron s that the filter cartridge is capable of removing. For example, a 30 micron cartridge will remove particulates as small as 30 micron while a 5 micron filter cartridge will remove particulates as small as 5 micron . The lower the micron rating of the filter cartridge, the tighter the filter and the smaller the particle size it can remove.

For sediment filters, generally a “nominal” rating is used, meaning that a high percentage of particles of the rated size are removed. An “Absolute” rating means that >99.99% of the particles of the rated size are removed. Rainfresh ceramic cartridges have a 0.3 micron absolute rating, meaning that they remove > 99.99% of particles as small as 0.3 micron .

VOC (Volatile Organic Compounds) are a class of organic chemicals that are known to be harmful to human health. VOC s enter ground water from a variety of sources such as oil spills, pesticide run-off, boat traffic in lakes and rivers, flushing industrial solvents and cleaners into the environment etc. VOC are regarded as potentially cancer-causing and should be removed from all drinking water supplies.

Rainfresh Drinking Water System models UCS3, QS1, QS2 and filter cartridge models LR1 & VC1 are tested and certified for reduction of VOC from water.

Trihalomethanes (THM ) – CHEMICALS

THM are chemical compounds formed by the reaction of disinfectants such as chlorine , with natural organic compounds (decaying leaves & vegetation). Many THM were also used over the years as solvents and refrigerants and now sometimes find their way into our drinking water supplies. THMs most commonly found in drinking water are chloroform, bromodichloromethane (BDCM), dibromochloromethane (DBCM) and bromoform, although over 50 are known to be present in various drinking water supplies.

THM are considered possible carcinogens (cancer-causing) in humans. According to Health Canada, animal studies indicate a link between specific THM and tumours. Some human studies also link THM with colorectal cancers & reproductive problems.

What is Chlorine ?

Chlorine is the most common chemical used by municipalities around the world to make water safe to drink. Almost all municipal treatment plants in North America use chlorine for primary or secondary disinfection. Chlorine can form cancerous by-products with certain organic compounds present in water. In addition chlorine renders an offensive taste and odour to water and to beverages made from such water. Coffee and tea tastes much better when chlorine is removed from water. Many people have reported to be allergic to chlorine in the water.

Chlorine from drinking water can be effectively reduced by activated carbon filter cartridges. All Rainfresh Drinking Water Systems reduce chlorine effectively. For whole house reduction of chlorine , Rainfresh CCF systems are recommended.
