Polypropylene Sediment Filter Cartridge
A$25.00
The Polypropylene Sediment Filter Cartridge is designed as Stage 1 filtration for compatible whole house water filtration systems, helping reduce dirt, sand, rust, silt and other suspended particles before they reach downstream filters.
Available in 10" × 4.5" and 20" × 4.5" sizes, this 1 micron sediment filter uses a triple-layer polypropylene depth-filtration structure to provide strong contaminant-holding capacity while maintaining reliable water flow.

Product Overview
Sediment filtration is an important first stage in a multi-stage whole house water filtration system.
The Polypropylene Sediment Filter Cartridge is designed to capture particulate matter from the incoming water supply before it reaches carbon, heavy metal or other specialty filtration cartridges.
Its three-layer depth-filtration structure captures particles throughout the filter media rather than only on the outer surface, helping provide high contaminant-holding capacity and longer service life.
Manufactured from 100% polypropylene, the cartridge uses fine melt-blown fibre technology and a thermally bonded construction with no glues, binders or adhesives.

The brochure states that the cartridge is designed to reduce dirt, sand, silt, rust and other debris while helping protect downstream filters, plumbing and appliances.
Available Sizes
Choose from two Polypropylene Sediment Filter Cartridge sizes:
Sediment Filter 20" × 4.5"
Designed for compatible 20-inch Big Blue / Big White whole house filter housings.
Sediment Filter 10" × 4.5"
Designed for compatible 10-inch Big Blue / Big White whole house filter housings.
Both options supplied by Filtered Water Systems use 1 micron sediment filtration.
Make sure you select the correct cartridge size for your existing filter housing before ordering.
1 Micron Sediment Filtration
The Polypropylene Sediment Filter Cartridge provides 1 micron filtration, designed to capture fine particulate matter from the incoming water supply.
It helps reduce:
Dirt
Sand
Rust
Silt
Sediment
Suspended particles
Other particulate debris
This makes it particularly suitable as a pre-filter before more specialised carbon or contaminant-reduction cartridges.
Stage 1 Whole House Filtration
The Polypropylene Sediment Filter Cartridge is designed primarily for use as Stage 1 in a multi-stage whole house filtration system.
Installing sediment filtration first helps capture dirt and particulate matter before water reaches the more specialised cartridges installed after it.
This can help protect downstream filters such as:
Carbon Block Filters
Matrikx CTO Carbon Block Filters
Heavy Metal Carbon Filters
Other specialty filtration cartridges
The brochure specifically notes that the cartridge helps protect plumbing, appliances and downstream filtration stages from sediment and debris.
Compatible Systems
The Polypropylene Sediment Filter Cartridge is designed for compatible Big Blue / Big White whole house and high-flow filtration systems.
Available sizes are:
10" × 4.5"
20" × 4.5"
It can be used in compatible single-stage or multi-stage systems where the cartridge dimensions match the filter housing.

Suitable Water Applications
The Polypropylene Sediment Filter Cartridge can be used as sediment pre-filtration for suitable:
Town water
Tank water
Rainwater
Bore water
The correct filtration setup should always be selected according to the condition and quality of the incoming water supply.
Tank, rainwater and bore-water applications may require additional treatment or disinfection depending on the water quality.

Understanding Micron Ratings
A filter's micron rating indicates the approximate particle size the filtration media is designed to target.
A 1 micron sediment cartridge provides finer particulate filtration than higher-rated sediment cartridges such as 5, 10 or 20 micron filters.
However, micron rating alone does not determine overall cartridge performance or filter life.
Incoming water quality, sediment levels, water usage and flow rate can all influence filtration performance.
Filter Replacement
The Polypropylene Sediment Filter Cartridge should be replaced every 12 months to help maintain water flow and overall filtration performance.
Actual cartridge life can vary depending on:
Incoming water quality
Sediment levels
Water usage
Flow rate
Cartridge size
Overall filtration system configuration
Water supplies containing higher sediment levels may require the cartridge to be replaced earlier.
Replacing the sediment cartridge as required also helps protect the carbon and specialty filtration cartridges installed after it.
