Depth Filtration at High Flow with the 20 inch 5 Micron String Wound Filter
The 20 inch 5 Micron String Wound Filter is a depth-type sediment filter made from polypropylene yarn wound in graded layers around a porous core. Its long body captures sand, rust, silt and limescale particles throughout its depth and gives long service on high-flow lines.

01Problem & Solution
A Surface-Only Filter Saturates Early
Problem
A Short Cartridge Means Frequent Maintenance
On lines with high water use, short cartridges fill in no time. Dirt building up at the surface weakens the flow, pressure falls, and frequent replacement drives up the cost.
Solution
Long Body, Deep Capture
The 20 inch 5 Micron String Wound Filter combines its long body with a graded winding structure. Particles are captured across different layers, capacity rises and the replacement interval lengthens.
02Key Features
Wound, High-Capacity, Versatile
The 20 inch 5 Micron String Wound Filter is a dependable pre-filter for heavily used lines.
5 Micron Filtration
Holds back sand, rust, silt and limescale particles larger than 5 micron.
Graded Winding Structure
Yarn winding that tightens from outside in delivers depth filtration and high dirt-holding capacity.
Large Winding Surface
A 20 inch body can accumulate far more sediment than a 10 inch cartridge.
Supported Core
The core structure helps the cartridge hold its shape under pressure.
Food-Contact Grade
Made from polypropylene suitable for drinking water filtration; it leaves no taste or odour.
Standard 20 inch Size
Compatible with common 20″ filter housings; it can be used regardless of brand.
03Technical Specifications
Product Details
| Feature | Value | What it does |
|---|---|---|
| Product Type | String Wound Sediment 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. |
| Micron Rating | 5 Micron | The smallest particle the filter holds back. The lower the figure, the finer the sediment it catches. |
| Material | Polypropylene Yarn | What it is made of. A metal body is preferred on a pressurised line, plastic on a chemical one. |
| Filtration Type | Depth Filtration | How the filter holds material back. |
| Compatibility | Standard 20" Filter Housings | Which units and housings it works with. Compare it with yours before ordering. |
04Applications
Where Is It Used?
The 20 inch 5 Micron String Wound Filter is used for pre-filtration on lines with high water use.
- Building & Villa Inlets
- Commercial Systems
- Industrial Pre-Filtration
- Well & Borehole Water Lines
- Greenhouse & Irrigation Lines
- Food & Beverage Production
- Pre-Pump Filtration
- Service & Installation Engineers
05How It Works
How Does the 20 inch 5 Micron String Wound Filter Work?
-
Fitted into the Housing
The cartridge is fitted into the standard 20 inch housing at the first stage of the line.
-
Water Enters the Wound Layers
Water from the line travels inwards through the loose outer winding on the cartridge’s surface.
-
Captured in Depth
Coarse particles are held in the outer layers, fine particles in the progressively tighter inner windings.
-
Clear Water Continues On
Freed of sediment, the water is collected in the core cavity and passed to the next stage.
-
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?
When choosing the 20 inch 5 Micron String Wound Filter, consider the housing size, the flow rate and the type of application.
Housing Size
This cartridge is for standard 20 inch housings; 10 inch and Big Blue housings take different sizes.
Flow Requirement
On lines with high consumption, the 20 inch size gives longer life and less pressure loss.
Construction Choice
String wound is strong at depth filtration; spun filters are generally more economical.
Micron Rating
5 micron is a balanced choice for a first stage; 1 micron filters finer but fills more quickly.
07Maintenance and Use
Replacement Notes
Replaced on time, the 20 inch 5 Micron String Wound Filter protects the whole line.
- This cartridge is not washable; sediment penetrates the depth of the winding and cannot be flushed out.
- Weakening flow and falling pressure are the first signs that replacement is due.
- Before replacement, shut off the water line, release the pressure inside the housing and check the O-ring.
- After fitting the new cartridge, run off the first water produced a few times to rinse the line.
08Frequently Asked Questions
Common Questions
What does the 20 inch 5 Micron String Wound Filter do?
It holds back suspended solids such as sand, rust, silt and limescale particles. Its long body and wound structure perform depth filtration, protecting the first stage of the treatment system.
How does it differ from a 10 inch cartridge?
The difference is length. Being twice as long, the 20 inch cartridge offers a larger winding surface; on the same water it lasts longer and pressure loss at high flow stays lower.
How does it differ from a spun filter?
The difference is in how they are made. A spun filter is formed from melt-blown fibre in a single piece; a string wound filter is made from polypropylene yarn wound around a core. String wound is strong at depth filtration.
Is it compatible with a Big Blue housing?
No. Standard 20 inch and 20 inch Big Blue cartridges are different diameters. If you have a Big Blue housing, choose a cartridge made for that diameter.
How often should it be replaced?
Replacement frequency depends on how dirty the water is and on daily consumption. Water with a high sediment load needs more frequent replacement, clean mains water less often; weakening flow is the most reliable indicator.
