PURETEC MAXIPLUS SEDIMENT CARTRIDGE

Puretec PX05MP2 5 Micron Polyspun Sediment Cartridge

The Puretec PX05MP2 is a genuine MaxiPlus sediment replacement cartridge designed to reduce dirt, rust, sand, silt, algae and other suspended particles from compatible water filtration systems.

Manufactured from virgin polypropylene, the cartridge uses Puretec's graded-density polyspun construction to provide depth filtration throughout the filter media rather than relying only on the outside surface.

The PX05MP2 has a nominal 5 micron rating, uses the large 4.5 inch × 20 inch MaxiPlus format and has a manufacturer-listed cartridge flow rate of up to 156 litres per minute.

Quick answer: the Puretec PX05MP2 is a genuine 5 micron, 4.5" × 20" polyspun sediment cartridge for compatible Puretec MaxiPlus filtration systems. It is designed for high-capacity sediment removal and is used in current systems including the WH2-55, WH2-60 and selected FilterWall models. It is a sediment filter only and should not be treated as a chlorine, taste or odour cartridge.

WHAT IT DOES

What Does the Puretec PX05MP2 Filter?

The PX05MP2 is a dedicated sediment filtration cartridge. Its job is to capture suspended particulate material as water passes through the filter media.

Dirt & Sediment

Reduces suspended dirt and sediment that can accumulate in a water supply or filtration system.

```

Rust, Sand & Silt

Puretec specifically identifies rust, sand and silt among the particulate material targeted by its PX Series cartridges.

Algae & Particles

The PX Series is also designed to capture algae and other suspended particles from compatible water supplies.

```
HOW IT WORKS

Graded-Density Depth Filtration

The PX05MP2 is made from virgin polypropylene that is spun and melted during manufacture to form a graded polyspun filtration structure.

This construction provides depth filtration, allowing particulate material to be captured throughout the thickness of the cartridge.

Outer Layers

Larger particles can be captured toward the outside of the cartridge before water moves deeper through the media.

```

Deeper Filtration

Finer particulate material can travel further into the graded media before being captured.

No Centre Core

Puretec designs the PX Series without a centre core restricting the internal filtration area.

```
HIGH-CAPACITY SEDIMENT FILTRATION

Large 20-Inch MaxiPlus Format

The PX05MP2 uses Puretec's larger 4.5" × 20" cartridge format, giving it substantially more filtration media than smaller slimline or 10-inch cartridges.

Puretec lists the individual PX05MP2 cartridge at up to 156 L/min. This is the cartridge flow specification and should not be confused with the maximum flow rate of the complete filtration system.

For example, systems using the PX05MP2 may be rated at substantially lower whole-system flow rates because other cartridges, housings, pipework and system components also affect performance.

IMPORTANT DISTINCTION

The PX05MP2 Is a Sediment Filter, Not a Carbon Filter

The PX05MP2 is designed for particulate filtration. It does not perform the same role as an activated carbon cartridge.

PX05MP2 Sediment Cartridge

Targets dirt, rust, sand, silt, algae and other suspended particles.

```

CB10MP2 Carbon Cartridge

Provides carbon treatment for chlorine, unwanted taste and odour while also providing sediment reduction.

```
Do not expect a sediment cartridge to reduce chlorine or unwanted taste and odour. Where those treatment functions are required, use the applicable carbon stage specified for the filtration system.

SYSTEM COMPATIBILITY

Which Puretec Systems Use the PX05MP2?

Puretec currently specifies the PX05MP2 in a range of systems built around the 20-inch MaxiPlus cartridge format.

Puretec WH2-55

The PX05MP2 is specified as the sediment stage in compatible WH2-55 whole-house filtration systems.

```

Puretec WH2-60

The current WH2-60 uses the PX05MP2 as stage one followed by a CB10MP2 carbon block cartridge.

Puretec FilterWall F5

Current FilterWall F5 systems include the PX05MP2 as part of their multi-stage whole-home filtration arrangement.

Puretec FilterWall F6

Current FilterWall F6 systems also use the PX05MP2 as their polyspun sediment filtration stage.

FilterWall IM2 / IMF2

Selected in-wall FilterWall configurations specify the PX05MP2 as the first sediment filtration stage.

TSI-25MP2 Housings

Puretec's TSI-MP replacement guide lists the PX05MP2 for compatible 20-inch MaxiPlus mains-water sediment applications.

Micron Rating 5 micron 5 micron
Diameter 4.5" 4.5"
Length 20" 10"
Media Graded polyspun polypropylene Graded polyspun polypropylene
Interchangeable No No

If your existing cartridge or system specifies PX05MP1, do not order the longer PX05MP2 as a substitute.

IS IT RIGHT FOR ME?

Check Before Ordering

A Good Match When

Your filtration system specifically lists PX05MP2 or calls for a Puretec 5 micron 4.5" × 20" MaxiPlus polyspun sediment cartridge.

```

Check First When

You only know that your cartridge is 20 inches long but have not confirmed whether the housing accepts the larger 4.5-inch MaxiPlus format.

Choose Another Type When

You need chlorine, taste, odour, scale or other specialised treatment rather than sediment filtration alone.

```
WHEN TO REPLACE

How Often Should the PX05MP2 Be Replaced?

Puretec service guides for filtration systems using MaxiPlus replacement cartridges generally specify replacement approximately every 6–12 months, depending on water quality and usage.

A sediment cartridge can require earlier replacement where the incoming water carries greater particulate loading.

  • Applicable 6–12 month service interval has been reached
  • Water flow has noticeably reduced
  • Pressure drop through the filter has increased
  • Cartridge is heavily loaded with visible sediment
  • Water supply has experienced unusual sediment disturbance
  • Previous replacement date is unknown
WHY SERVICE LIFE VARIES

What Affects Sediment Cartridge Life?

Incoming Water Quality

A supply containing more rust, sand, silt or other suspended material will load the cartridge faster.

```

Water Consumption

Higher water use passes more water and potentially more particulate material through the cartridge.

Supply Disturbance

Plumbing work, mains disturbances or changing source-water conditions can temporarily increase sediment loading.

```
CARTRIDGE REPLACEMENT

What Is Involved in Replacing a PX05MP2?

The PX05MP2 is installed inside a compatible 20-inch MaxiPlus filter housing. It is not a sealed quick-twist cartridge.

  • Confirm the system requires PX05MP2
  • Turn off the incoming water supply
  • Relieve pressure through a downstream tap or system relief point
  • Open the correct filter housing
  • Remove the used sediment cartridge
  • Clean the accessible filter bowl
  • Inspect the housing O-ring and sealing surfaces
  • Install the new PX05MP2 correctly
  • Reassemble the filter housing
  • Restore water pressure gradually
  • Check the housing and connections for leaks
  • Confirm normal water flow after servicing
HOUSING MAINTENANCE

Check the Seal While the Housing Is Open

Opening a MaxiPlus housing for cartridge replacement also gives you an opportunity to inspect the filter bowl, O-ring and accessible sealing surfaces.

The O-ring should be correctly seated and free from obvious damage before the bowl is reassembled.

If the housing, valve, O-ring or plumbing connections are damaged, additional parts or repair work may be required separately from the cartridge itself.

DIY OR PROFESSIONAL SERVICE

Can the PX05MP2 Be Replaced Yourself?

Cartridge replacement may be suitable for owner servicing where the installed filtration system is designed for it and the incoming water can be safely isolated and depressurised.

A 20-inch MaxiPlus housing is relatively large and can contain a significant volume of water, so there should be suitable access below and around the housing before attempting removal.

Use professional servicing if the system is difficult to isolate or access. A seized housing, damaged seal, leaking valve or plumbing problem may require more than a standard cartridge change.
PROFESSIONAL REPLACEMENT

Professional PX05MP2 Cartridge Replacement

Professional cartridge replacement may be available in selected Installed Today Brisbane and Gold Coast service areas.

A cartridge service can include removal of the existing filter, cleaning of the accessible housing, checking accessible seals, installation of the replacement PX05MP2 and a final check for leaks and normal water flow after repressurisation.

Additional cartridges, replacement housings, valves, fittings and plumbing repairs are separate where required.

COMMON QUESTIONS

Questions About the Puretec PX05MP2

What Is the Puretec PX05MP2?

It is a genuine Puretec 5 micron graded polyspun sediment cartridge in the 4.5" × 20" MaxiPlus format.

What Does the PX05MP2 Filter?

Puretec specifies the PX Series for sediment, dirt, rust, sand, silt, algae and other particulate removal.

Does It Reduce Chlorine?

No. The PX05MP2 is a sediment cartridge. Chlorine reduction requires an appropriate carbon filtration stage.

Does It Improve Taste and Odour?

It is not designed as a taste-and-odour cartridge. If taste and odour reduction is required, check the carbon cartridge specified for your system.

What Is the Micron Rating?

The PX05MP2 has a nominal filtration rating of 5 micron.

What Size Is It?

It uses Puretec's 4.5 inch × 20 inch MaxiPlus format.

What Is the Listed Flow Rate?

Puretec lists the individual PX05MP2 cartridge at up to 156 L/min. The complete system in which it is installed may have a lower maximum flow rate.

Does It Fit the Puretec WH2-60?

Yes. Puretec specifies the PX05MP2 as the first-stage sediment cartridge in the current WH2-60.

Does It Fit FilterWall Systems?

Yes, selected current FilterWall F5, F6, IM2 and IMF2 configurations specify the PX05MP2.

Is PX05MP2 the Same as PX05MP1?

No. Both are 5 micron MaxiPlus sediment cartridges, but PX05MP2 is 20 inches long while PX05MP1 is 10 inches long.

How Often Should It Be Replaced?

Puretec system guides commonly specify approximately 6–12 months for applicable replacement cartridges, depending on water quality and usage.

Can Reduced Flow Mean the Cartridge Is Loaded?

Yes. Sediment accumulation can increase pressure drop and reduce flow, although other plumbing or filtration issues can cause similar symptoms.

Can I Replace It Myself?

Potentially, if the filtration system is designed for owner servicing and you can safely isolate, depressurise, open and correctly reseal the housing.

Can Installed Today Replace the Cartridge?

Professional replacement may be available in eligible Brisbane and Gold Coast service areas where the filtration system is accessible and in serviceable condition.
