Big Blue · Large Diameter & Long Body
Long-Life Pre-Filtration with the 20 inch 5 Micron Big Blue Cartridge Filter
The 20 inch 5 Micron Big Blue Cartridge Filter is a large-diameter, long-bodied polypropylene cartridge that holds back suspended solids such as sand, rust, silt and sediment. It keeps pressure loss limited on high-flow building inlet lines and markedly extends the replacement interval.

- 20" Big Blue
- Micron rating
- 5 Micron
- Material
- Polypropylene (PP)
01Problem & Solution
Frequent Replacement on Busy Lines Is Wearing
Problem
A Short Cartridge Means Constant Maintenance
Building, estate and well water lines carry a heavy sediment load. Short cartridges fill quickly; frequent replacement costs both labour and consumables, and a clogged filter drops the pressure.
Solution
The Largest Filtration Surface
With its large diameter and long body, the 20 inch 5 Micron Big Blue Cartridge Filter holds far more sediment. The replacement interval lengthens, flow stays easy and the line runs without interruption.
02Key Features
Maximum Capacity, Easy Flow
The 20 inch 5 Micron Big Blue Cartridge Filter is the highest-capacity cartridge option for main-line filtration.
5 Micron Filtration
Holds back sand, rust, silt and turbidity-causing particles larger than 5 micron.
Large Diameter & Long Body
The Big Blue diameter and the 20 inch length together give the highest sediment-holding capacity.
Long Replacement Interval
On the same water it serves far longer than shorter cartridges.
Low Pressure Loss
Filters high-flow main lines without restricting the flow significantly.
Protects the Installation
By holding sediment at the inlet, it protects taps, mixers, boilers and appliances from particles.
Standard Big Blue Compatibility
Compatible with common 20 inch Big Blue filter housings; it can be used regardless of brand.
03Technical Specifications
Product Details
| Feature | Value | What it does |
|---|---|---|
| Product Type | Sediment Filter | The product family it belongs to. When buying a spare, the family alone is not enough; the size and model must match too. |
| Size | 20 inch Big Blue | The physical size. If a spare does not match this, it will not go into the housing. |
| Micron Rating | 5 Micron | The smallest particle the filter holds back. The lower the figure, the finer the sediment it catches. |
| Material | Polypropylene Fibre | What it is made of. A metal body is preferred on a pressurised line, plastic on a chemical one. |
| Stage | Stage 1 (Pre-Filter) | The number of treatment stages. Each stage takes out a different kind of contamination. |
| Compatibility | 20" Big Blue Filter Housings | Which units and housings it works with. Compare it with yours before ordering. |

05How It Works
How Does the 20 inch 5 Micron Big Blue Cartridge Filter Work?
Fitted into the Housing
The cartridge is fitted into the 20 inch Big Blue housing at the inlet of the main line.
Water Passes from Outside In
Water from the main line travels inwards through the cartridge’s wide outer surface.
Particles Are Captured in Stages
Coarse particles are held in the outer layer, fine particles in the progressively denser inner layers.
Clear Water Goes Out to the Line
Freed of sediment, the water reaches the plumbing — and any further treatment stages — noticeably cleaner.
Replaced When Saturated
When the cartridge fills with sediment the flow weakens; at that point it should be replaced with a new one.
06Making the Right Choice
20 inch or 10 inch Big Blue?
When choosing the 20 inch 5 Micron Big Blue Cartridge Filter, consider the housing size, the flow rate and the sediment load.
Housing Size
This cartridge is for 20 inch Big Blue housings; 10 inch housings take a shorter cartridge.
Flow Requirement
On building and estate lines with high water use, the 20 inch size gives easier flow.
Sediment Load
On sediment-laden sources such as well water, a larger cartridge markedly reduces how often it must be replaced.
Installation Space
A 20 inch housing is longer; leave enough clearance beneath it for cartridge changes.
07Maintenance and Use
Replacement Notes
Replaced on time, the 20 inch 5 Micron Big Blue Cartridge Filter protects the whole line.
- This cartridge is not washable; once saturated it should not be cleaned but replaced with a new one.
- Weakening flow at the taps and falling pressure are the first signs that the cartridge has filled.
- Before replacement, close the main valve, release the pressure in the housing and check the large O-ring.
- After fitting the new cartridge, run the line for a few minutes to rinse it and check for leaks.
08Frequently Asked Questions
Common Questions
What does the 20 inch 5 Micron Big Blue Cartridge Filter do?
It holds back suspended solids such as sand, rust, silt and sediment. Its large diameter and long body let it work on high-flow main lines, protecting the plumbing and the treatment stages from particles.
How does it differ from a 10 inch Big Blue cartridge?
The diameter is the same, the length differs. Being twice as long, the 20 inch cartridge holds more sediment; on the same water the replacement interval lengthens and pressure loss at high flow stays lower.
Will it fit a standard 20 inch housing?
No. Big Blue cartridges fit Big Blue housings only. If you have a standard slim 20 inch housing, choose a cartridge made for that diameter.
Does it remove chlorine and limescale?
No. This is a mechanical sediment filter; it does not remove dissolved substances. Activated carbon is needed for chlorine, taste and odour; softening for hardness; and a reverse osmosis stage for salts and TDS.
How often should it be replaced?
Replacement frequency depends on how dirty the water is and on the flow rate of the line. Sediment-laden sources such as well water need more frequent replacement; weakening flow is the most reliable indicator.
