PURETEC MAXIPLUS PLEATED SEDIMENT CARTRIDGE
Puretec PL20MP1 20 Micron Pleated Sediment Cartridge
The Puretec PL20MP1 is a genuine washable sediment cartridge designed for pre-filtration and reduction of dirt, rust, sand, silt and other suspended particulate material in compatible water filtration systems.
Puretec manufactures the PL Series from durable non-woven reusable polyester media pleated around a polypropylene core. The pleated design creates a large filtration surface area to increase dirt-holding capacity while maintaining high water-flow capability.
The PL20MP1 has a nominal 20 micron rating, measures 4.5" × 10" in Puretec's MaxiPlus format and has a manufacturer-listed individual flow rate of up to 94 litres per minute.
Quick answer:
the Puretec PL20MP1 is a 20 micron, 4.5" × 10" MaxiPlus washable pleated sediment cartridge. It is not a 1 micron or 20-inch cartridge. Puretec lists the PL20MP1 at up to 94 L/min and specifies it as the first filtration stage in systems including FilterWall F3/F3E, EM2-75, EM2-80 and compatible Hybrid systems.

IMPORTANT CORRECTION
PL20MP1 Means 20 Micron, 10-Inch MaxiPlus
The PL20MP1 should not be described as a 1 micron, 20" × 2.5" cartridge.
Puretec's current specification identifies the PL20MP1 as a 20 micron, 4.5" × 10" MaxiPlus cartridge.
Check the full cartridge code before ordering.
PL20MP1 and PL20MP2 are both 20 micron pleated cartridges, but MP1 is the 10-inch MaxiPlus version while MP2 is the 20-inch MaxiPlus version.
WHAT IT DOES
Coarse Sediment Pre-Filtration
The PL20MP1 is designed to capture suspended particulate material before water reaches finer downstream filtration stages.
Dirt
The pleated polyester surface captures suspended dirt carried through the incoming water supply.
```
Rust
Helps reduce particulate rust before water passes through finer sediment or carbon cartridges.
Sand & Silt
Designed to reduce suspended sand, silt and similar particulate material.
20 Micron Filtration
The nominal 20 micron rating makes the PL20MP1 suitable as a coarse first-stage sediment filter.
High Sediment Loads
Puretec specifically identifies the PL Series as suitable for pre-filtration in high-sediment applications.
Sediment Only
The cartridge does not contain activated carbon for dedicated chlorine, taste or odour treatment.
```
PLEATED POLYESTER MEDIA
Large Filtration Area in a 10-Inch MaxiPlus Cartridge
Puretec manufactures the PL Series using non-woven polyester fabric pleated around a polypropylene support core.
The pleated construction increases the available media surface area, improving dirt-holding capacity compared with a flat filtration surface.
The pleat ends are sealed into the cartridge end caps and the overlap seam is sonically welded to help reduce internal bypass through the cartridge.
WASHABLE DESIGN
Can the PL20MP1 Be Cleaned?
Yes. Puretec specifically lists the PL20MP1 as a washable pleated sediment cartridge.
Surface sediment may be cleaned from the polyester media where appropriate, which can help restore flow during the cartridge's service period.
Washable does not mean permanent.
The cartridge should still be replaced in accordance with the maintenance schedule and condition of the complete filtration system.
MEDIA CONSTRUCTION
Polyester Media With a Polypropylene Core
The PL20MP1 should not be described as a pleated polypropylene filter cartridge.
Puretec specifies the actual filter media as non-woven polyester fabric. A polypropylene core is used internally to support the pleated media.
This differs from Puretec's PX Series, which uses spun polypropylene as the filtration media itself.

FLOW RATE
Understanding the 94 L/min Rating
Puretec lists the individual PL20MP1 cartridge at up to 94 litres per minute.
This is the cartridge specification, not the flow rate of every complete filtration system that uses it.
Complete-system flow can be lower because of filter housings, additional cartridges, UV treatment, valves, pipework and available incoming pressure.
FILTERWALL F3 COMPATIBILITY
Stage One in Puretec FilterWall F3 & F3E
Puretec currently specifies the PL20MP1 as the first filtration stage in FilterWall F3 and F3E systems.
Stage 1 – PL20MP1
20 micron washable pleated sediment pre-filtration.
```
Stage 2 – PX05MP1
5 micron graded polyspun sediment filtration.
Stage 3 – CB10MP1
10 micron bonded activated-carbon treatment for chlorine, unwanted taste and odour reduction.
```
Puretec lists the complete FilterWall F3/F3E system at a nominal 30 L/min. The PL20MP1's 94 L/min individual cartridge rating does not change the complete-system rating.
EM SERIES COMPATIBILITY
PL20MP1 in Puretec EM2-75 & EM2-80
Puretec also specifies the PL20MP1 as the first stage in compatible dual-stage EM rainwater filtration systems.
Puretec EM2-75
Stage one uses PL20MP1, followed by PX01MP1 1 micron polyspun sediment filtration. Puretec lists the complete system at up to 75 L/min.
```
Puretec EM2-80
Also uses PL20MP1 followed by PX01MP1. Puretec lists the complete system at up to 80 L/min.
```
HYBRID SYSTEM COMPATIBILITY
PL20MP1 in Compatible Puretec Hybrid Systems
Puretec specifies the PL20MP1 as a sediment stage in compatible 10-inch Hybrid filtration and UV systems.
Hybrid R3
Uses PL20MP1 as the first sediment stage followed by PX01MP1 and the applicable Puretec UV treatment components.
```
Hybrid E8
Puretec identifies PL20MP1 as the 20 micron particulate stage in the compatible Hybrid E8 system.
```
Always confirm the exact Hybrid model because Puretec uses different cartridge lengths and combinations across its Hybrid range.

WHEN TO SERVICE
How Often Should the PL20MP1 Be Replaced?
The correct service interval depends on the complete filtration system, water quality and usage.
For FilterWall F3/F3E systems, Puretec specifies cartridge replacement approximately every 6–12 months, or earlier if water flow decreases or treatment performance changes.
Other systems using PL20MP1 can have their own maintenance schedules, so the guide for the installed system should always take priority.
- Applicable system service interval has been reached
- Water flow has noticeably reduced
- Pleated media is heavily loaded
- Incoming sediment levels have increased
- Cleaning no longer restores suitable flow
- Previous cartridge replacement date is unknown
MEDIA RESISTANCE
Suitable for a Range of Filtration Applications
Puretec states that the durable polyester media used in the PL Series is resistant to bacterial and chemical attack.
This describes the durability of the cartridge material itself. It should not be interpreted as the PL20MP1 disinfecting water or providing bacterial removal.
CARTRIDGE REPLACEMENT
What Is Involved in Replacing a PL20MP1?
The PL20MP1 is a conventional drop-in cartridge installed inside a compatible reusable 10-inch MaxiPlus housing.
- Confirm the installed system specifies PL20MP1
- Isolate the incoming water supply
- Relieve pressure from the filtration system
