10 Inch Combined Filter (Sediment / Carbon)
The Combined Filter (also called a dual media filter) is essentially two different filters blended into one, with a granular activated coconut carbon (GAC/UDF) filter, and a 1 Micron Polypropylene (PP) Sediment filter.
Features:
- Dual media filtration
- 100% virgin grooved polypropylene prefilter
- 100% pure coconut shell-activated carbon media bed
- Iodine rating of 1,000 for improved chlorine reduction
- 100% virgin polypropylene cartridge construction
- All parts are sealed using advanced friction welding
- Top-mounted thermoplastic gasket
Keep In mind
The Combination filter will remove sediment, dirt, rust, fine particles, and absorb chlorine as well as some bad odours. The Filter will not address issues in water such as Bacteria, viruses, Heavy Metals, mineral content, pesticides, or herbicides. If these are issues that you are concerned about we would recommend contacting Filtershop, and our sales staff will be happy to assist you with selecting the right filters for your requirements.
First Section: 1 Micron Melted Spray (Polypropylene/PP) Sediment Filter
A Melted-Spray (Polypropylene) 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.
Sediment filters are rated by a micron number. A micron is a unit of length that is equal to one millionth (10-6) of a meter. The Melted spray section of the Combined filter is 1 Micron.

Second Section: Granular Activated Coconut Carbon (GAC)
The second part of the Combined Filter contains Granular Activated Coconut Carbon (GAC).
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.
The Activated Carbon has an iodine rating of 1000mg/g.
Many carbons preferentially adsorb small molecules. Iodine number is the most fundamental parameter used to characterize activated carbon performance. It is a measure of activity level (a higher number indicates a higher degree of activation) often reported in mg/g (typical range 300–1200 mg/g). It is a measure of the micropore content of the activated carbon (0 to 20 Å, or up to 2 nm) by adsorption of iodine from solution. It is equivalent to the surface area of carbon between 900 and 1100 m2/g. So essentially the greater the Iodine Number Rating on an Activated Carbon Block, the more effectively the carbon will absorb things such as chlorine and organic molecules.
