Chlorine Reduction at High Flow with the 20 inch GAC Carbon Cartridge Filter
The 20 inch GAC Carbon Cartridge Filter is a long-bodied treatment cartridge filled with porous granular activated carbon. It adsorbs chlorine, odour, off-taste and organic compounds, and its large carbon volume lets it work on high-flow lines without restricting the flow significantly.

01Problem & Solution
At High Flow the Carbon Saturates Quickly
Problem
Little Carbon, Short Contact Time
Carbon adsorption depends on contact time. On high-flow lines the carbon volume in a small cartridge saturates quickly; chlorine is not fully removed and the membrane is put at risk.
Solution
More Carbon Volume
With a body twice as long, the 20 inch GAC Carbon Cartridge Filter contains far more granular carbon. Contact time lengthens and chlorine and odour reduction stays effective even at high flow.
02Key Features
High Capacity, Easy Flow
The 20 inch GAC Carbon Cartridge Filter is the chlorine and odour stage for heavily used lines.
Chlorine Reduction
By adsorbing free chlorine from mains water, it improves the taste and smell of the water.
High Carbon Volume
The 20 inch length gives more granular carbon and a longer service life.
Organic Compound Adsorption
Helps capture the organic compounds that give water colour, taste and odour.
Low Pressure Loss
The granular structure restricts flow less than carbon block, an advantage at high throughput.
Protects the Membrane
By removing chlorine, it helps extend the life of the reverse osmosis membrane.
Standard 20 inch Size
Compatible with common 20″ filter housings; it can be used regardless of brand.

04Applications
Where Is It Used?
The 20 inch GAC Carbon Cartridge Filter is used for chlorine reduction on lines with high water use.
- Building & Villa Inlets
- Commercial Systems
- Cafés & Restaurants
- Hotels & Housing Estates
- Well & Borehole Water Lines
- RO System Pre-Treatment
- Annual Filter Replacement
- Service & Installation Engineers
05How It Works
How Does the 20 inch GAC Carbon Cartridge Filter Work?
It Comes After the Sediment Stage
Water that has passed the sediment filter reaches the carbon stage free of coarse particles.
It Enters the Long Granular Bed
Water passes between the granular activated carbon particles arranged along the 20 inch body.
Adsorption Takes Place
Chlorine, odour and organic molecules attach to the porous carbon surface and leave the water.
Clean Water Goes Out to the Line
Free of chlorine, the water reaches the membrane or the point of use far more safely.
Replaced When Saturated
When the carbon surface is saturated, chlorine reduction weakens and a change in taste and smell becomes noticeable.
06Making the Right Choice
20 inch or 10 inch?
When choosing the 20 inch GAC Carbon Cartridge Filter, consider the housing size, the flow rate and the chlorine level.
Housing Size
This cartridge is for standard 20 inch housings; 10 inch and jumbo housings take a different size.
Flow Requirement
As flow rises the contact time shortens, which is why the 20 inch size is preferred on busy lines.
Construction Choice
The GAC granular structure restricts flow less; CTO carbon block gives longer contact time.
Chlorine Level
On mains supplies with a high chlorine level, a larger carbon volume extends the replacement interval.
07Maintenance and Use
Replacement Notes
Replaced on time, the 20 inch GAC Carbon Cartridge Filter keeps protecting the membrane.
- This cartridge is not washable; once the carbon surface is saturated it must be replaced with a new one.
- When a taste or smell of chlorine becomes noticeable in the water, it is time to replace it.
- On first use the water may run cloudy because of carbon dust; run it off a few times to rinse.
- An overdue carbon stage starts letting chlorine through, and that can damage the membrane permanently.
08Frequently Asked Questions
Common Questions
What does the 20 inch GAC Carbon Cartridge Filter do?
It removes chlorine, odour, off-taste and organic compounds from the water by adsorption. The high carbon volume in its long body lets it work effectively on high-flow lines while protecting the membrane.
How does it differ from a 10 inch cartridge?
The difference is length. Being twice as long, the 20 inch cartridge contains more granular carbon; the water is in contact with it longer, which means more effective removal at high flow and a longer life.
How does it differ from CTO carbon block?
CTO is a pressed block; GAC is a granular fill. The block structure gives longer contact time, the granular structure restricts flow less. In most systems the two are used together as consecutive stages.
Is it compatible with a jumbo housing?
No. Standard 20 inch and 20 inch jumbo cartridges are different diameters. If you have a jumbo housing, choose a cartridge made for that diameter.
Does it remove limescale and sediment?
No. Carbon works by adsorption; it does not reduce hardness and does not remove dissolved salts. A sediment filter is needed for sand and silt, and a softening stage for hardness.
