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 .
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.

I just wanted to pass along that the customer service you provided us was top notch. My wife and I really appreciated you taking our concerns seriously the entire way, and the fact that you had asked for the old cartridge to investigate it spoke volumes about wanting to do what needs to be done to provide your end users (consumers) a great product. We basically challenged you to return our faith in Rainfresh products, and you accomplished that and so much more!
Thank you Rainfresh!!

I have been using Rainfresh BC2 filters for years. They are very good. However, sometimes one out of five filters is so dense that it lowers the water pressure. The last one that had this problem would not allow me to access water in two different places in the house.
