PURETEC SEDIMENT FILTER CARTRIDGE
Puretec PX05MP1 5 Micron Polyspun Sediment Cartridge
The Puretec PX05MP1 is a MaxiPlus sediment filter cartridge designed to remove particulate material such as sediment, rust, sand, silt and algae from water before it reaches downstream filtration stages, plumbing fixtures or other water-treatment components.
Puretec uses a graded polyspun construction that provides depth filtration throughout the cartridge rather than relying only on the outer surface.
The PX05MP1 has a nominal 5 micron rating, uses the larger 4.5 inch × 10 inch MaxiPlus format and is specified by Puretec for a flow rate of up to 76 litres per minute.
Quick answer:
the Puretec PX05MP1 is a genuine 5 micron, 4.5" × 10" graded polyspun sediment cartridge for compatible MaxiPlus filter housings and Puretec systems that specify this cartridge. It is designed to capture sediment, rust, sand, silt and algae while providing high-flow particulate pre-filtration.

WHAT IT DOES
What Does the Puretec PX05MP1 Filter?
The PX05MP1 is a sediment cartridge. Its purpose is to physically capture suspended particulate material as water moves through the graded polyspun media.
Sediment & Dirt
Captures particulate material that can contribute to cloudy water, sediment accumulation and loading of downstream filters.
```
Sand, Silt & Rust
Puretec specifies the PX Series for removal of sand, silt and rust from the water supply.
Algae
Puretec also identifies algae removal among the applications for its PX Series sediment cartridges.
```
HOW IT WORKS
Graded-Density Depth Filtration
The PX05MP1 is constructed as a graded polyspun sediment cartridge.
Rather than trapping all material on one flat surface, the depth-filter design allows particulate material to be captured through the thickness of the filtration media.
This makes the cartridge suited to sediment pre-filtration applications where dirt-loading capacity and water flow are important.
Outer Filtration Layers
Larger particulate material can be captured toward the outer portion of the cartridge media.
```
Deeper Filtration
Finer particles continue further into the graded media before being captured.
Depth Loading
Using the depth of the cartridge media allows particulate loading to be distributed through more of the filter structure.

5 MICRON SEDIMENT FILTRATION
Designed for Fine Particulate Pre-Filtration
The PX05MP1 has a nominal 5 micron rating, making it a relatively fine sediment filtration stage for compatible water-treatment systems.
Its primary role is particulate filtration. It should not be treated as a carbon cartridge or as a replacement for filtration stages specifically designed for chlorine, taste, odour or dissolved contaminant reduction.
Where a multi-stage system uses both sediment and carbon cartridges, the PX05MP1 will commonly perform the sediment pre-filtration role before the downstream carbon stage.
CARTRIDGE SIZE
Puretec MaxiPlus 4.5" × 10" Format
The PX05MP1 uses Puretec's larger MaxiPlus 4.5 inch × 10 inch cartridge format.
This is different from standard slimline 2.5-inch cartridges, so the physical cartridge format must be checked before ordering.
Check the cartridge size before purchase.
A 10-inch cartridge is not automatically interchangeable with every 10-inch filter. Confirm that the housing or filtration system is designed to accept the 4.5-inch diameter MaxiPlus format and specifically supports the PX05MP1 or an equivalent approved cartridge.
FLOW PERFORMANCE
High-Flow Sediment Filtration
Puretec lists the PX05MP1 with a flow range up to 76 litres per minute in applicable system specifications.
Actual flow through an installed filtration system is also affected by the filter housing, other cartridges, pipework, incoming pressure, water conditions and the complete system's rated flow.
Where the PX05MP1 is used in a multi-stage system, the lowest-flow component can determine the practical maximum flow of the complete filtration setup.

SYSTEM COMPATIBILITY
Which Systems Use the PX05MP1?
The PX05MP1 is used in compatible Puretec filtration systems designed around the MaxiPlus 4.5" × 10" cartridge format.
Puretec specifically lists the PX05MP1 as the sediment-stage replacement cartridge for systems including the WH2-30 and WH2-35.
Puretec WH2-30
The PX05MP1 is specified as the first-stage sediment cartridge in the WH2-30 whole-house filtration system.
```
Puretec WH2-35
Puretec's replacement guide also lists the PX05MP1 as the sediment cartridge for the WH2-35.
Other Compatible MaxiPlus Housings
Other systems may use the cartridge where their manufacturer or system specification calls for the same cartridge format and filtration specification.
```
MULTI-STAGE FILTRATION
Why Use a Sediment Cartridge Before a Carbon Filter?
In dual-stage systems, sediment filtration is commonly positioned before the carbon stage.
The PX05MP1 captures particulate material before it reaches the downstream cartridge, helping the next filtration stage focus on its intended treatment role.
For example, Puretec specifies the PX05MP1 as stage one and the CB10MP1 carbon block as stage two in the WH2-30 system.
WHEN TO REPLACE
How Often Should the PX05MP1 Be Replaced?
Puretec's whole-house maintenance guidance gives a general cartridge replacement interval of approximately 6–12 months, depending on water quality and usage.
Sediment cartridge life can vary considerably because the PX05MP1 physically captures particles from the incoming supply.
- Applicable 6–12 month service interval has been reached
- Water flow has noticeably reduced
- Pressure drop through the filtration system has increased
- Cartridge has become heavily loaded with sediment
- Incoming water has experienced unusually high sediment loading
- Previous replacement date is unknown
WHY SERVICE LIFE VARIES
What Affects Sediment Cartridge Life?
Incoming Water Quality
Water containing more suspended sediment will load the cartridge faster than a cleaner incoming supply.
```
Water Usage
A property using a greater volume of water will pass more particulate material through the filtration system.
Upstream Conditions
Changes in mains supply, tank water conditions, plumbing work or sediment disturbance can alter how quickly the cartridge loads.
```
CARTRIDGE REPLACEMENT
What Is Involved in Replacing a PX05MP1?
The exact replacement process depends on the filter housing or Puretec filtration system in which the cartridge is installed.
- Turn off the incoming water supply
- Relieve pressure from the filtration system
- Open the appropriate filter housing
- Remove the used sediment cartridge
- Clean the filter bowl
- Inspect the housing O-ring and sealing surfaces
- Insert the new PX05MP1 correctly
- Reassemble the filter housing
- Restore water pressure gradually
- Check the housing and connections for leaks
O-RING MAINTENANCE
Check the Filter Housing Seal During Replacement
Whenever a cartridge housing is opened, the filter bowl O-ring and sealing surfaces should be checked before reassembly.
Puretec's whole-house maintenance guidance recommends checking O-rings for damage and replacing them where required. Puretec also provides a general recommendation to replace applicable housing O-rings approximately every 3–5 years.
Where lubrication is required, Puretec specifies a light coating of suitable food-grade silicone lubricant or similar product.
DIY OR PROFESSIONAL SERVICE
Can You Replace the PX05MP1 Yourself?
Cartridge replacement can be completed by the owner where the filtration system is designed for user servicing and the water supply can be safely isolated and depressurised.
Correct housing reassembly is important because the O-ring and filter bowl need to reseal correctly before the system is repressurised.
Use professional servicing if you are unsure.
If the filtration housing is difficult to isolate, difficult to open, leaking or showing damaged seals or fittings, professional cartridge replacement is a practical option.
