 Granular Activated Carbon (GAC) - provides protection for home drinking water from chemical compounds. GAC also traps organic material thereby removing bad tastes, colour and odours.
Even though GAC is sufficient to correct the problems of 85% of today's households, to make the process more complete, we have addedKDF to our cartridges.
KDF -the exchange of electrons significantly removes harmful heavy metal such as lead, mercury and aluminium. KDF also makes our purifiers completely bacteriostatic by killing fungus, algae and bacteria.
Glacier 2 Stage Industrial Water Purifier.
Glacier water purifiers differ from normal water filters in that it employs a 5 micron pre-sediment filter that removes particles as well a KDF/GAC purifying Cartridge further removing contaminants from all tap water.
What is KDF?
It is a high purity Zinc and Copper alloy that has been patented in the USA.
-
It Removes chlorine from water supplies
-
Has a Long Life
-
Extends the life of the GAC
-
Protects bed from bacterial growth
-
Also removes up to 98% of lead and heavy metals.
 It is known as today's precious metal when it comes to water purification, it has revolutionized the water treatment industry. It is a high purity zinc and copper alloy Media bed which has been tested to remove chlorine, heavy metals, lead, mercury and other hazardous chemicals which could be found in municipally treated water. It also controls the growth of algae, fungi and bacteria. The KDF Process involves the give and take of electrons in contaminated water turning contaminants into harmless components such as chlorine to chloride, which is not toxic. Other contaminants such as lead simple bond to the KDF.
Eg.
-
Chlorine removal:
-
KDF + Chlorine2 - Zn +++2CI.
-
Zinc loses 2 electrons (oxidation)
-
Copper gains 2 electrons (reduction)
What is GAC?
It is an activated carbon that removes chlorine, THM's (organic matter that reacts with chlorine) and a multitude of other contaminants that could be found in tap water and improves the taste and smell of tap water.
What are Doctors Saying About The KDF/GAC Purification Compared to Other Water Treatment Products?
"In the past I have used a system called reverse osmosis. However, you should know that the process is slow and wastes a lot of water, which is why I finally stopped using it, since I live in a part of the country where water is scarce. I am now in favour of a system that combines a carbon filter with a zinc and copper alloy called KDF. This dual system removes most impurities and is affordable and simple. The KDF puts small amount of copper and zinc into the water, which is healthful." Dr Andrew Weil A leading American medical health specialist and opinion leader.

Specifications:
-
Water first flows through a 5 micron pre-sediment particle filter to remove dirt, rust and other sediment present in the water.
-
Then the water flows through a second KDF/GAC Cartridge which utilizes 1 pound of KDF-55 media, which contains an anti-microbial agent to prolong the life of the filter. It also Contains high performance granular active Coconut Shell Carbon.
