PURETEC CARBON BLOCK CARTRIDGE
Puretec CB10MP1 10 Micron Carbon Block Cartridge
The Puretec CB10MP1 is a MaxiPlus carbon block replacement cartridge designed to significantly reduce chlorine, unwanted taste, odour and sediment from compatible water filtration systems.
Constructed from bonded activated carbon, the CB10MP1 provides a high-capacity carbon filtration stage without releasing carbon fines during normal use.
The cartridge has a nominal 10 micron rating, uses Puretec's 4.5 inch × 10 inch MaxiPlus format and is rated for flow rates up to 30 litres per minute.
Quick answer:
the Puretec CB10MP1 is a genuine 10 micron carbon block cartridge for compatible Puretec MaxiPlus filtration systems. It uses bonded activated carbon to significantly reduce chlorine, taste, odour and sediment, with a listed flow rate of up to 30 L/min. Check your filtration system model before ordering to confirm the CB10MP1 is the specified replacement cartridge.

WHAT IT DOES
What Does the Puretec CB10MP1 Reduce?
The CB10MP1 is designed as a carbon treatment cartridge rather than a sediment-only filter.
Chlorine
Puretec specifies the CB10MP1 for significant chlorine reduction in compatible water filtration applications.
```
Taste & Odour
The activated carbon media is designed to reduce unwanted taste and odour associated with the incoming water supply.
Sediment
The carbon block also provides sediment reduction through its nominal 10 micron filtration structure.
```
Puretec uses the term “removes” to indicate significant reduction rather than guaranteed 100% removal.
CARBON BLOCK TECHNOLOGY
How Does the CB10MP1 Work?
The CB10MP1 is manufactured from bonded activated carbon. Water passes through the carbon block, allowing the cartridge to provide both carbon treatment and particulate filtration.
Puretec specifies the bonded design as providing strong contaminant capacity while avoiding the release of loose carbon fines during normal filtration.
Activated Carbon Media
The carbon media provides the treatment stage responsible for reducing chlorine and unwanted taste and odour.
```
Bonded Construction
The carbon is formed into a solid block rather than being supplied as loose granular media.
High Dirt-Holding Tolerance
Puretec specifies enhanced dirt-holding capacity to help utilise more of the carbon block during its service life.
```
30 L/MIN CARBON FILTRATION
High-Flow Carbon Treatment for Compatible Systems
The Puretec CB10MP1 is listed for flow rates up to 30 litres per minute, making it suitable for compatible higher-flow filtration applications.
Actual flow through an installed filtration system also depends on the complete system design, water pressure, pipework, filter housings and any other cartridges installed in sequence.
Where the CB10MP1 is installed in the Puretec WH2-30, the complete system is also rated to a maximum flow of 30 L/min.
CARTRIDGE SIZE
Puretec MaxiPlus 4.5" × 10" Format
The CB10MP1 uses Puretec's larger MaxiPlus 4.5 inch × 10 inch cartridge format.
This is different from a slimline 2.5-inch cartridge, so a filter should not be considered compatible simply because both cartridges are described as 10-inch models.
Confirm compatibility before ordering.
Check that your filtration system or housing specifically accepts the MaxiPlus 4.5" × 10" format and calls for the CB10MP1 or an approved equivalent specification.

SYSTEM COMPATIBILITY
Which Puretec Systems Use the CB10MP1?
Puretec specifies the CB10MP1 in several filtration systems that use the MaxiPlus 4.5" × 10" carbon stage.
Puretec WH1-30
Puretec's replacement guide lists the CB10MP1 as the cartridge for the WH1-30 whole-house filtration system.
```
Puretec WH2-30
The CB10MP1 is the second-stage carbon cartridge specified for the WH2-30 dual-stage whole-house system.
Puretec WH2-35
Puretec also specifies the CB10MP1 as the second-stage carbon cartridge in the WH2-35.
Selected FilterWall Systems
Puretec uses the CB10MP1 as a carbon filtration stage in selected 10-inch MaxiPlus FilterWall configurations.
Compatible MaxiPlus Housings
Other applications may use the CB10MP1 where the filtration-system specification specifically calls for this size, flow and cartridge model.
Not Every 10-Inch Housing
Compatibility with generic or slimline 10-inch filter housings should not be assumed without checking the housing dimensions and system requirements.
```
TWO-STAGE SYSTEMS
Using the CB10MP1 After a Sediment Cartridge
In the Puretec WH2-30 and WH2-35, the CB10MP1 is used after a dedicated sediment cartridge.
The PX05MP1 5 micron sediment cartridge is installed first to capture dirt, rust, sand, silt and other particulate material before water reaches the carbon block.
The CB10MP1 then performs the carbon stage for chlorine, unwanted taste, odour and additional sediment reduction.
Stage 1 – PX05MP1
5 micron graded polyspun sediment cartridge for particulate pre-filtration.
```
Stage 2 – CB10MP1
10 micron bonded carbon block cartridge for chlorine, taste, odour and sediment reduction.
```
WHEN TO REPLACE
How Often Should the CB10MP1 Be Replaced?
Puretec recommends replacing applicable cartridges approximately every 6–12 months, when the cartridge reaches its capacity or when unwanted taste or odour returns, whichever occurs first.
Actual cartridge life depends on incoming water quality, water usage and flow conditions.
- 6–12 month service interval has been reached
- Rated filtration capacity has been reached
- Chlorine taste or odour begins to return
- Water flow has noticeably reduced
- Cartridge has experienced high sediment loading
- Previous replacement date is unknown
CARTRIDGE CAPACITY
What Does the Listed 196,841 Litre Capacity Mean?
Puretec lists the CB10MP1 with a nominal cartridge capacity of up to 196,841 litres.
This should not be treated as a guaranteed service life for every installation. Puretec states that capacity is dependent on incoming water quality and flow.
The cartridge may therefore require replacement before reaching the listed capacity where incoming chlorine, sediment or general water demand is higher.
WHEN PERFORMANCE CHANGES
Signs Your Carbon Cartridge May Need Attention
Taste or Odour Returns
A return of the taste or odour being treated by the carbon stage can indicate the cartridge has reached its service capacity.
```
Reduced Water Flow
Increasing pressure drop may indicate that the cartridge has become heavily loaded with particulate material.
Service Interval Reached
Routine replacement should not be delayed simply because no obvious change in water appearance has occurred.
```
CARTRIDGE REPLACEMENT
What Is Involved in Replacing a CB10MP1?
The replacement procedure depends on the Puretec housing or filtration system in which the cartridge is installed.
- Turn off the incoming water supply
- Relieve pressure from the filtration system
- Open the correct filter housing
- Remove the used carbon cartridge
- Clean the filter bowl as required
- Inspect the housing O-ring and sealing surfaces
- Install the new CB10MP1 in the correct stage
- Reassemble the housing correctly
- Restore water pressure gradually
- Check the housing and connections for leaks
- Flush the replacement cartridge as required before normal use
O-RING MAINTENANCE
Check the Housing Seal Whenever the Filter Is Opened
Filter housing O-rings should be inspected when the housing is opened for cartridge replacement.
Puretec's whole-house maintenance guidance recommends replacing damaged seals and provides a general recommendation for applicable O-rings to be replaced approximately every 3–5 years.
Correctly seated and maintained housing seals are important before the filtration system is repressurised.
DIY OR PROFESSIONAL SERVICE
Can the CB10MP1 Be Replaced Yourself?
Cartridge replacement may be completed by the owner where the filtration system is designed for user servicing and the incoming water can be safely isolated and depressurised.
Correct cartridge placement and housing reassembly are important. The housing seal must be correctly seated and the system checked for leaks after water pressure is restored.
Professional servicing is available where required.
If the filtration system is difficult to isolate, the housing will not open normally, a seal or housing is damaged, or you are unsure of the correct cartridge sequence, professional cartridge replacement is a practical option.
PROFESSIONAL REPLACEMENT
Professional Cartridge Replacement Option
Professional cartridge replacement may be available in eligible Installed Today service areas.
A cartridge service can include removal of the existing CB10MP1, cleaning of the accessible filter housing, checking accessible seals, installing the new cartridge and checking the system for leaks and normal operation after repressurisation.
Replacement housings, valves, other cartridges, plumbing repairs or additional components are separate where required.
