WHAT IT DOES
What Does the Puretec IN149C Reduce?
The IN149C is more than a basic carbon-only inline cartridge. Puretec combines activated carbon with premium-grade KDF media to provide several treatment functions in one compact cartridge.
Chlorine
The carbon and KDF treatment media are designed to reduce chlorine in compatible drinking-water applications.
```
Sediment
The cartridge provides nominal 1 micron filtration for fine suspended particulate material.
Taste & Odour
Activated carbon helps reduce unwanted taste and odour in the incoming water supply.
Heavy Metals
Puretec specifically identifies heavy-metal reduction as part of the IN149C's KDF and carbon treatment.
Inline Filtration
The sealed cartridge allows water to be treated directly within the water line without a separate reusable filter bowl.
Compact Applications
The slimline design is intended for installations where available filtration space is limited.
```
TRIPLE-ACTION INLINE FILTRATION
KDF, Carbon & Fine Filtration in One Cartridge
Puretec describes the IN149C as a triple-action inline cartridge.
The cartridge combines fine nominal filtration with activated-carbon treatment and KDF media, allowing one sealed inline filter to address sediment, chlorine, unwanted taste, odour and manufacturer-specified heavy-metal reduction.
This combination makes the IN149C particularly suited to compact point-of-use drinking-water systems where a conventional multi-housing arrangement is not required.
IMPORTANT SPECIFICATION
The IN149C Is a 1 Micron Cartridge
Puretec's current manufacturer specification lists the IN149C at 1 micron.
It should therefore not be described as a 5 micron cartridge.
Check the exact model code when replacing an inline filter.
Puretec produces several IN Series cartridges with different filtration media, connections and treatment specifications. Confirm that your existing system specifically calls for IN149C.

IL-UB COMPATIBILITY
Replacement Cartridge for the Puretec IL-UB
Puretec currently specifies the IN149C as the replacement cartridge for the IL-UB inline undersink filtration system.
The IL-UB uses the IN149C's KDF and carbon media to reduce chlorine, sediment, unwanted taste, odour and heavy metals while maintaining a compact installation beneath the kitchen bench.
1 Micron System
The current IL-UB is manufacturer-listed as a 1 micron inline filtration system.
```
1/4" Quick Connect
The cartridge and compatible system use quick-connect tubing connections for the filtered-water line.
Horizontal or Vertical
Puretec states that the IL-UB filtration arrangement can be mounted horizontally or vertically where installation requirements allow.
```
IL-TM COMPATIBILITY
Replacement Cartridge for Compatible Puretec IL-TM Systems
Puretec also specifies the IN149C for compatible IL-TM inline undersink systems.
These systems combine the inline cartridge with a three-way mixer arrangement so filtered drinking water can be delivered separately from the normal hot and cold supply through a compatible mixer tap.
Always confirm the exact installed IL-TM model before ordering, particularly where an older or discontinued system is being serviced.
FRIDGE & APPLIANCE APPLICATIONS
Compact Inline Filtration Where Space Is Limited
Puretec describes the IN Series as suitable for a variety of compact inline filtration applications.
Fridges
Suitable for compatible refrigerator water lines requiring the IN149C connection and treatment specification.
```
Ice Machines
Can be used in compatible ice-machine supply lines where flow, pressure and connection requirements are appropriate.
Water Coolers
The slimline inline format suits selected drinking-water cooler applications.
Drinking Fountains
Puretec also identifies drinking fountains among the potential IN Series applications.
Undersink Systems
IN149C is the genuine cartridge used in compatible Puretec undersink filtration systems.
Limited Installation Space
The sealed inline format avoids the larger reusable bowl required by a conventional cartridge housing.
```
QUICK-CONNECT DESIGN
1/4" Quick-Connect Cartridge Connections
The IN149C uses 1/4" quick-connect connections rather than the threaded female connections used on the related IN149 cartridge.
This distinction is important when selecting a replacement. IN149 and IN149C share similar KDF and carbon treatment characteristics but use different connection arrangements.
IN149 and IN149C are not identical connection types.
IN149C uses 1/4" quick-connect connections, while the IN149 is manufacturer-listed with 1/4" BSP female connections.
OPERATING CONDITIONS
Compatible System Conditions
Where the IN149C is used in the current Puretec IL-UB system, Puretec specifies the following operating conditions for the complete filtration arrangement.
| System Condition |
Puretec IL-UB Specification |
| Water Temperature |
0–38°C, protect from freezing |
| Maximum Pressure |
500 kPa |
| Connection |

| Nominal Micron Rating |
1 micron |
Operating limits belong to the complete installed filtration system. Check the requirements of the actual fridge, cooler, undersink unit or other appliance where the IN149C is being installed.
PRESSURE PROTECTION
Check Incoming Water Pressure
Puretec specifies a maximum pressure of 500 kPa for the current IL-UB system.
Where line pressure exceeds the applicable limit, Puretec requires an approved pressure-limiting device to be installed in accordance with the relevant plumbing requirements.
Do not assume every inline application has the same pressure limit.
Always check the specifications of the complete filtration system, refrigerator, ice machine, cooler or other connected appliance.
WHEN TO REPLACE
When Should the IN149C Be Replaced?
Cartridge replacement frequency depends on the complete Puretec system, incoming water quality and water usage.
Rather than relying on a universal fixed replacement interval, follow the maintenance instructions applicable to the installed IL-UB, IL-TM or other compatible system.
- Manufacturer service interval for the installed system has been reached
- Filtered-water flow has noticeably reduced
- Chlorine taste begins to return
- Unwanted taste or odour becomes noticeable
- Incoming water conditions have changed
- Previous cartridge replacement date is unknown
REPLACEMENT FORMAT
A Sealed Inline Cartridge, Not a Drop-In Filter
The IN149C is a sealed inline cartridge. Unlike cartridges such as PX051, GC051 or CB951, it does not sit inside a separate reusable filter bowl.
The complete inline filter body is replaced during servicing, and the tubing reconnects to the cartridge through its integrated quick-connect ports.
This compact format can simplify routine cartridge replacement where the existing tubing, isolation and installation remain in serviceable condition.
REPLACEMENT PROCESS
What Is Involved in Replacing an IN149C?
- Confirm the installed cartridge is IN149C
- Confirm the tubing uses compatible 1/4" quick-connect fittings
- Isolate the incoming water supply
- Relieve pressure from the filtered-water line
- Disconnect the tubing from the existing cartridge
- Remove the old inline cartridge from its mounting position
- Install the replacement IN149C in the correct flow direction
- Reconnect the tubing fully into the quick-connect fittings
- Restore the water supply gradually
- Inspect all accessible connections for leakage
- Flush the new cartridge according to the applicable Puretec system instructions
BEFORE ORDERING
Check These Details First
- Existing replacement cartridge code is IN149C
- Required filtration rating is 1 micron
- Application requires KDF and carbon treatment
- Tubing connection is 1/4" quick connect
- Existing system or appliance is compatible with IN149C
- You have not confused IN149C with threaded IN149
- Incoming water can be isolated for cartridge replacement

DIY OR PROFESSIONAL REPLACEMENT
Can the IN149C Be Replaced Yourself?
Puretec describes the compatible IL-UB cartridge as a do-it-yourself replacement cartridge, and the quick-connect format is designed to simplify routine cartridge changes.
That does not mean every installation is identical. Fridge lines, cabinetry access, pressure-control devices, isolation valves and appliance connections can vary between properties.
Professional servicing may be appropriate where the installation is difficult to access or cannot be safely isolated.
Damaged tubing, fittings, valves or pressure-control components may require additional work beyond replacing the cartridge itself.
