Chlorine Reduction at High Flow with the 20 inch CTO Carbon Cartridge Filter
The 20 inch CTO Carbon Cartridge Filter is a long-bodied treatment cartridge made by compressing activated carbon into a solid block. It adsorbs chlorine, odour, off-taste and organic compounds and, with long contact time on high-flow lines, protects the membrane from the effects of chlorine.

01Problem & Solution
At High Flow the Contact Time Shortens
Problem
Fast Flow, Incomplete Chlorine Reduction
Carbon adsorption depends on contact time. On high-flow lines, water in a short cartridge does not spend enough time in contact with the carbon; chlorine is not fully removed and the membrane is put at risk.
Solution
More Carbon, Longer Contact
With a body twice as long, the 20 inch CTO Carbon Cartridge Filter offers more carbon volume. Water stays inside the block longer, so chlorine and odour reduction stays effective even at high flow.
02Key Features
Dense, High-Capacity, Compatible
The 20 inch CTO Carbon Cartridge Filter is the taste 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.
Long Block Body
The 20 inch length gives more carbon volume and a longer service life.
Organic Compound Adsorption
Helps capture the organic compounds that give water colour, taste and odour.
Reduces Carbon Carry-Over
The block structure markedly reduces the dust carry-over seen with granular carbon cartridges.
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.

|---|---|---|
| Product Type | Carbon Block (CTO) Filter | Which family the unit belongs to. Products in the same family can be used in place of one another. |
| Size | 20 inch (20") | The physical size. If a spare does not match this, it will not go into the housing. |
| Construction | Compressed Activated Carbon | How the unit is put together. A compact cabinet takes little room; an open system makes servicing easier. |
| Function | Chlorine, Taste and Odour Reduction | What the product does to the water. |
| Stage | Carbon Before the Membrane | The number of treatment stages. Each stage takes out a different kind of contamination. |

- Service & Installation Engineers
05How It Works
How Does the 20 inch CTO 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 Passes Through the Long Block Body
Water travels slowly from the outer surface of the 20 inch carbon block towards the centre.
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, and the membrane surface is protected.
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 CTO 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.
Chlorine Level
On mains supplies with a high chlorine level, a larger carbon volume extends the replacement interval.
Stage Layout
A sediment filter must sit ahead of it, and a softening stage for hardness must be planned separately.
07Maintenance and Use
Replacement Notes
Replaced on time, the 20 inch CTO 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.
- After fitting the new cartridge, run off the first water produced a few times to rinse out carbon dust.
- 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 CTO Carbon Cartridge Filter do?
It removes chlorine, odour, off-taste and organic compounds from the water by adsorption. Its long body lets it work effectively on high-flow lines and protects the reverse osmosis membrane from the effects of chlorine.
How does it differ from a 10 inch cartridge?
The difference is length. Being twice as long, the 20 inch cartridge contains more carbon; water stays inside the block longer, which means more effective chlorine reduction at high flow and a longer life.
How does it differ from a GAC carbon filter?
GAC consists of a granular carbon fill; CTO is a pressed block. The block structure gives longer contact time and less carbon carry-over, while the granular structure restricts flow less. In most systems the two are used in sequence.
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.
