PURETEC WHOLE-HOUSE FILTER SERVICE SET

Puretec PX05MP2 & CB10MP2 Service Kit

The Puretec PX05MP2 & CB10MP2 Service Kit combines the two genuine replacement cartridges used together in compatible Puretec dual-stage whole-house filtration systems.

The PX05MP2 provides 5 micron sediment filtration, targeting dirt, rust, sand, silt, algae and other suspended particles before the water reaches the CB10MP2 carbon block stage.

The CB10MP2 then provides 10 micron carbon filtration designed to significantly reduce chlorine, unwanted taste, odour and sediment. Together, the cartridges restore the original two-stage filtration arrangement used by systems including the Puretec WH2-55, WH2-60 and compatible FilterWall IM2 and IMF2 systems.

Quick answer: this service set contains the PX05MP2 5 micron sediment cartridge and CB10MP2 10 micron carbon block cartridge. Both are large 4.5" × 20" MaxiPlus cartridges. Puretec specifies this pairing for systems including the WH2-55, WH2-60, FilterWall IM2 and FilterWall IMF2. Check your system model before ordering.

WHAT'S INCLUDED

Two Genuine Puretec Replacement Cartridges

1 × Puretec PX05MP2

A 5 micron graded polyspun sediment cartridge in Puretec's 4.5" × 20" MaxiPlus format.

Designed to reduce dirt, rust, sand, silt, algae and suspended sediment.

```

1 × Puretec CB10MP2

A 10 micron bonded activated carbon block cartridge in the same 4.5" × 20" MaxiPlus format.

Designed to significantly reduce chlorine, unwanted taste, odour and sediment.

```

This product description covers the two-cartridge PX05MP2 and CB10MP2 service set. Puretec also offers the GR-WH255 Premium Care Kit for applicable systems, which includes these cartridges together with O-rings and food-grade lubricant.

SYSTEM COMPATIBILITY

Which Puretec Systems Use This Cartridge Pair?

Puretec specifies the PX05MP2 and CB10MP2 together in several current whole-house filtration systems.

Puretec WH2-55

Uses PX05MP2 as the sediment stage and CB10MP2 as the taste-and-odour carbon stage.

```

Puretec WH2-60

Uses the same PX05MP2 and CB10MP2 two-stage cartridge combination.

FilterWall IM2

Current Puretec FilterWall IM2 specifications list PX05MP2 as stage one and CB10MP2 as stage two.

FilterWall IMF2

Puretec's GR-WH255 care-kit information identifies FilterWall IMF2 systems as compatible with this cartridge pairing.

Selected TSI-MP Systems

Puretec also lists PX05MP2 and CB10MP2 as cartridge options for compatible 20-inch MaxiPlus TSI housings used on mains water.

Check the Model First

Do not assume compatibility with every Puretec whole-house system. Other models can use different cartridge sizes or filtration combinations.

```
TWO-STAGE FILTRATION

Why the PX05MP2 Comes Before the CB10MP2

The two cartridges perform different jobs and are designed to work in sequence.

The PX05MP2 sediment cartridge is installed first to capture suspended particulate material. The CB10MP2 carbon block cartridge follows it to provide chlorine, unwanted taste and odour reduction together with additional sediment filtration.

Keeping the cartridges in the manufacturer-specified order preserves the intended filtration sequence of compatible Puretec dual-stage systems.

STAGE 1

Puretec PX05MP2 Sediment Cartridge

The PX05MP2 is manufactured from virgin polypropylene using a graded polyspun construction.

Puretec's design provides depth filtration through the cartridge media and does not use a centre core that restricts the internal filtration area.

5 Micron

The PX05MP2 has a nominal filtration rating of 5 micron.

```

Graded Polyspun Media

Different layers of the media progressively capture suspended particulate material through the depth of the cartridge.

156 L/min Cartridge Rating

Puretec lists the individual PX05MP2 cartridge at a flow rate of up to 156 litres per minute.

```
STAGE 2

Puretec CB10MP2 Carbon Block Cartridge

The CB10MP2 is manufactured from bonded activated carbon and provides the carbon treatment stage within compatible systems.

Puretec specifies it for significant reduction of chlorine, unwanted taste, odour and sediment.

10 Micron

The bonded carbon block has a nominal filtration rating of 10 micron.

```

60 L/min Cartridge Rating

Puretec lists the individual CB10MP2 cartridge for flow rates up to 60 litres per minute.

Bonded Activated Carbon

The solid carbon-block construction is designed to provide treatment without releasing loose carbon fines during normal use.

```

Construction Virgin polypropylene, graded polyspun Bonded activated carbon
SYSTEM FLOW

Cartridge Flow Rate vs Whole-System Flow Rate

The individual cartridge flow ratings should not be used as the flow rating of the complete filtration system.

For example, Puretec currently lists the WH2-55 at up to 55 L/min and the WH2-60 at up to 60 L/min, even though the individual PX05MP2 cartridge is listed at up to 156 L/min.

Complete-system flow is determined by the combined effect of the cartridges, filter housings, connections, incoming pressure, pipework and other installation conditions.

CORRECT CARTRIDGE ORDER

Which Filter Goes First?

Stage 1 – PX05MP2

Install the 5 micron polyspun sediment cartridge in the first housing in the water-flow direction.

```

Stage 2 – CB10MP2

Install the 10 micron carbon block cartridge in the second housing after the sediment stage.

```
Keep the cartridges in the correct sequence. Puretec specifies PX05MP2 as the sediment stage and CB10MP2 as the downstream taste-and-odour carbon stage in compatible WH2 and FilterWall systems.
WHEN TO REPLACE

How Often Should the Cartridges Be Changed?

Puretec's whole-house maintenance guide provides a general cartridge replacement interval of 6–12 months, depending on water quality and usage.

Puretec also notes that replacing cartridges around every 6 months can help maintain filtration performance where operating conditions require it.

  • 6–12 month service interval has been reached
  • Water flow has noticeably reduced
  • Chlorine taste or unwanted odour begins to return
  • Sediment cartridge is heavily loaded
  • Water conditions have changed
  • Previous service date is unknown
WHY SERVICE LIFE VARIES

What Affects Cartridge Life?

Sediment Levels

Higher dirt, rust, sand or silt loading can cause the PX05MP2 to load more quickly.

```

Water Consumption

Higher household water usage moves a greater total volume through both cartridges.

Chlorine Loading

The concentration of chlorine in the incoming mains supply affects the treatment demand placed on the CB10MP2.

```
CARTRIDGE REPLACEMENT

What Is Involved in Replacing the Service Kit?

Both cartridges are conventional MaxiPlus filters installed inside reusable housings. They are not sealed quick-twist cartridges.

  • Confirm the filtration system uses PX05MP2 and CB10MP2
  • Turn off the incoming water supply
  • Relieve system pressure
  • Open both filter housings
  • Remove the existing cartridges
  • Clean the accessible filter bowls
  • Inspect the housing O-rings and sealing surfaces
  • Install PX05MP2 in stage one
  • Install CB10MP2 in stage two
  • Reassemble the housings correctly
  • Restore water pressure gradually
  • Check both housings and connections for leaks
  • Flush the system as required before normal use
O-RING MAINTENANCE

Check the Housing Seals During Servicing

Whenever the filter bowls are opened, the housing O-rings and sealing surfaces should be inspected before reassembly.

Puretec's whole-house maintenance guidance recommends replacing applicable O-rings approximately every 3–5 years to help maintain a watertight seal.

If your O-rings are also due, Puretec's manufacturer-packaged GR-WH255 Premium Care Kit may be worth considering because it combines the compatible genuine cartridges with O-rings and food-grade lubricant.

BEFORE ORDERING

Check These Details First

  • Existing cartridges are PX05MP2 and CB10MP2
  • System uses 4.5" × 20" MaxiPlus cartridges
  • PX05MP2 is installed as stage one
  • CB10MP2 is installed as stage two
  • Filter housings are accessible for servicing
  • Water can be isolated before opening the housings
  • O-rings are in serviceable condition
  • No damaged housings or valves require separate repair
DIY OR PROFESSIONAL SERVICE

Can You Replace the Cartridges Yourself?

Owner replacement may be practical where the filtration system is designed for routine servicing and you can safely isolate the incoming water, relieve pressure and correctly reseal both filter housings.

Large 20-inch MaxiPlus housings contain a significant amount of water and require suitable access underneath the filtration system for removal.

Use professional servicing if access or system condition is uncertain. A seized housing, damaged O-ring, leaking valve or existing plumbing problem may require additional work beyond a routine cartridge replacement.
PROFESSIONAL REPLACEMENT

Professional Whole-House Filter Servicing

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 cartridges, cleaning of accessible filter bowls, inspection of accessible seals, fitting the new PX05MP2 and CB10MP2 cartridges and checking for leaks and normal flow after repressurisation.

Replacement housings, O-rings, valves, fittings, additional cartridges and plumbing repairs are separate where required.
