A drinking water filter for filtering major water contaminates from tap water and other drinking water sources. The water filter a cylindrical cartridge for receiving a plurality of sponge filters used as dividers between different layers of filtration material and along a length of the cartridge. The sponge filters are designed to remove large and small sediments in the water from 1 to 100 microns in size and greater when the water is introduced through the cartridge. The layers of filtration material includes a layer of granulated zinc and copper alloy, a fine mesh carbon block, a layer of granulated ion exchange resin, a layer of granulated activated carbon and layer of granulated activated calcite. The carbon block and the granulated carbon material is used for removing chlorine, odor, color, cysts, protozoa and organic contaminants such as pesticides, herbicides, arsenic, mercury, and trihalomnethanes. The zinc and copper alloy is used for removing chlorine and heavy metals in the water and reducing bacteria in the water. The calcite is used to raise the pH in the filtered water when the pH is below neutral. |

DETAILED DESCRIPTION In view of the foregoing, it is a primary objective of the subject invention to provide an improved water filter used for various household uses.
Also, the water filter can be used for commercial and industrial applications where treated drinking, cooking and washing water is desired or required.
The water filter provides a consumer with protection against major water contaminants found in municipal water supplies and other drinking water sources.
Another object of the invention is the water filter removes contaminants in the water to below E.
P.
A.
recommended minimum levels.
Yet another object of drinking water filter is the filter is designed to remove large and small sediments in the water.
Also the filter, using a combination of a carbon block and a layer of granulated activated carbon, removes chlorine, trihalomethanes, hydrogen sulfide, pesticides, herbicides, toxic heavy metals (such as lead, organic mercury, organic arsenic and others), cysts, protozoa (including giardia and cryptosporidium), cancer-causing organic pollutants, micro-organisms and other foreign particles and organisms.
The filter gives treated water a sparkling clarity by screening material out of the water down to a one micron size.
A further object of the invention is the filter is designed to raise the water's pH when the pH is below neutral, thereby lowering acidity and increasing alkalinity, which is recommended by many nutritionists.
Still further, the water filter requires no plumbing and is received in a filter housing attached to a standard water faucet.
The filter housing can be disposed on a counter top for household use.
Also, the water filter housing can be attached to a water supply line and mounted under a kitchen sink.
The subject water filter costs pennies per gallon, is compact and space saving in design.
It eliminates the need to buy, lift and carry heavy water bottles.
The water filter has a filter life of treating 1500 gallons of tap water, which is a typical one year average drinking and cooking water use of a family of four
