This set of filters is the 6 month replacement filter set for the Domestic under the counter Reverse Osmosis (RO) systems and includes a 10 inch Melted Spray Sediment filter, a 10 inch Granulated Active Carbon (GAC), a 10 inch Active Carbon Block and a Taste and Odour filter (T33).
MELTED-SPRAY SEDIMENT FILTER (1st Stage)
The Sediment filter is usually the first stage in a water filtration system. It serves to remove visible dirt particles such as mud, rust, and sand from the water.
A Melted-spray filter cartridge has a multi-layer structure and is self-bonded, thus not making use of a chemical binder.
After passing through this filter, the water may appear to be clean. However, looks can be deceiving and most water contaminants are smaller than what our eyes can see. These contaminants may not be removable by the sole use of a sediment filter.
GRANULATED ACTIVE CARBON(GAC)FILTER (2nd Stage)
Granular Active Carbon is carbon that has been treated with oxygen to make it porous, but it has also been broken up into granules to further increase the surface area for chemical bondage to occur. The water passes through the GAC filter, allowing the organic materials and chlorine to effectively bond with the carbon molecules, thus removing these from the water.
ACTIVATED CARBON BLOCK (3rd Stage)
Activated carbon is a form of carbon that has been treated with oxygen to make it very porous, allowing for a larger surface area for chemical reactions to occur. The carbon absorbs organic materials from the water it comes into contact with.
The Activated Carbon Block is enclosed in a 5-micron filter to catch tiny carbon dust particles that may break off during the filtration.
TASTE AND ODOUR FILTER (T33) (5th Stage)
The Taste and Odour filter is typically used as a final stage in a Reverse Osmosis Filtration system. T33 is also made from activated carbon and serves to absorb any of the unwanted tastes and smells that may have resulted from the filtration process.
