Charcoal Water Filters




Charcoal as a water filter medium is derived from coconut husk. Charcoal readily absorbs impurities as the water passes along it's surface area. The charcoal can be ground into small pieces or formed into a solid, yet porous, block in order to increase it's surface area for the attachment of toxins. Charcoal water filters comprises possibly 95% of those in use domestically, because they are simple to install, relatively economical and effectively remove many toxins found in the environment. According to the EPA, charcoal filters must be "rated" to remove particles 1 micron or larger to effectively remove the most deadly of contaminants, Cryptosporidium and Giardia. An average charcoal filter will last a family 6-9 months. Some charcoal filters are enhanced by the use of activated silver, which provides extra antibacterial protection. Minerals in solution can still permeate a charcoal filter. These minerals are essential to health.

Reverse Osmosis Water Filters



Reverse Osmosis water filters use a fine membrane to filter through osmotic process. They take everything out of the water, leaving it pure. Usually installed under-sink, they require service every few months to install a new membrane.


Distiller Water Filters

Water distillers use electricity to heat tap water to boiling point. Impurities are left in the boiling container and the purified condensate drains back into a clean container. They require a fair degree of power and cannot give immediate supply, because the boiling process must be completed before water is available. There is now a number of reports that distilled water is not good to drink long term because it leaches nutrients from the body, being the most 'unnatural' of water.


Ionized Water Filters

Ionized water is electronically enhanced water that has been run over positive and negative electrodes and becomes ionized, by separating the water, and the minerals it contains into alkaline and acidic water. They are created simultaneously, 70% Alkaline water and 30% Acid water. Both waters have extraordinary properties and benefits, however, their respective uses could not be more different. The Alkaline Ionized Water is used for drinking and demonstrates strong antioxidant effects on the body, while Acidic Ionized Water is used on the outside of the body and is proven to kill many types of bacteria, including E. coli.
