Aqua Blue H2O 20" x 4.5" Big Blue 10 Micron PP Sediment Filter Cartridge
Heavy-Duty Whole House Sediment Water Filter | 100% Polypropylene | High Dirt-Holding Capacity
Keep your water filtration system performing at its best with the Aqua Blue H2O 20" x 4.5" Big Blue 10 Micron PP Sediment Filter Cartridge.
Designed for whole house water filtration, rainwater and tank water systems, bore water pre-filtration, commercial filtration and general sediment removal, this high-capacity replacement cartridge helps reduce dirt, rust, sand, silt and other suspended particles before they travel further through your plumbing or filtration system.
The 10 micron filtration rating provides an excellent balance between effective sediment removal and water flow, making it a practical choice for many residential and commercial applications.
Manufactured from 100% polypropylene (PP) using a melt-blown, graded-density construction, the cartridge provides excellent dirt-holding capacity while maintaining reliable water flow throughout its service life.
Why Choose a 10 Micron Sediment Filter?
A 10 micron sediment filter is an excellent general-purpose choice when you need effective sediment filtration without unnecessarily restricting water flow.
It is designed to capture suspended particles such as:
-
Dirt and debris
-
Rust particles
-
Sand
-
Silt
-
Pipe scale and sediment
-
Other suspended particulate matter
For many whole house water filter systems, 10 micron provides an ideal balance between filtration performance, flow rate and filter life.
It can also be used as a pre-filter before finer filtration stages, carbon filters or other water treatment equipment.
Three-Layer Graded-Density Filtration
Unlike a simple surface filter, this Aqua Blue H2O sediment cartridge uses a graded-depth polypropylene structure designed to trap particles throughout the filter media.
Larger particles are captured toward the outer layers while progressively smaller particles are captured deeper within the cartridge.
This depth-filtration design helps provide:
Higher dirt-holding capacity – sediment can be captured throughout the filter media rather than only on the outer surface.
Longer effective filter life – graded-density construction helps prevent the outside of the cartridge from becoming prematurely blocked.
Reliable water flow – designed to provide effective sediment reduction while maintaining practical flow through the filtration system.
No binders or adhesives – the polypropylene filtration media is thermally bonded during manufacture.
Ideal for Whole House Water Filtration
The 20" x 4.5" Big Blue format is commonly used where higher water capacity is required compared with smaller standard cartridges.
It is suitable for many applications including:
-
Whole house water filtration systems
-
Residential water filtration
-
Rainwater filtration
-
Tank water filtration
-
Bore water pre-filtration
-
Sediment pre-filtration
-
Commercial water filtration systems
-
Plumbing protection
-
Pre-filtration before carbon filtration
-
Replacement cartridges for compatible 20" Big Blue filter housings
This makes it an excellent replacement sediment cartridge for customers looking for a 20 inch Big Blue water filter for residential or commercial use.
Helps Protect Your Plumbing & Filtration Equipment
Sediment in water can accumulate in plumbing fixtures, valves, taps and downstream filtration equipment.
Installing a quality sediment pre-filter can help reduce the amount of particulate matter reaching the rest of your system.
By capturing dirt, rust, sand and silt at the filtration stage, the Aqua Blue H2O cartridge can also help protect downstream filters from excessive sediment loading.
For multi-stage systems, a sediment filter is commonly installed as the first filtration stage, followed by additional filtration media depending on the required water treatment.
100% Polypropylene Construction
The filter media is manufactured from 100% polypropylene (PP), a material widely used in water filtration applications.
The melt-blown filtration media is formed using thermal bonding without the use of conventional binders or adhesives.
This provides a clean and effective sediment filtration medium suitable for a wide variety of water filtration applications.

What Does a 10 Micron Filter Remove?
A micron is one-thousandth of a millimetre.
The 10 micron rating means this cartridge is designed for sediment filtration at approximately the 10 micron level.
It is particularly useful for reducing visible and fine suspended particles while generally providing greater flow capacity than very fine sediment cartridges.
For customers who are unsure which micron rating to choose, the general guide below can help.
Which Micron Filter Should I Choose?
| Micron | Filtration Level | Typical Application |
|---|---|---|
| 1 Micron | Extra Fine | Very fine sediment and small suspended particles |
| 5 Micron | Fine | Fine sediment and general high-level sediment filtration |
| 10 Micron | Medium / General Purpose | Excellent balance of sediment filtration and water flow |
| 20 Micron | Coarser | Higher sediment loads and applications where higher flow is preferred |
10 Micron is an excellent general-purpose choice for many whole house and commercial sediment filtration systems.
For heavily contaminated water, a staged filtration system may also be used, with a coarser sediment cartridge installed before a finer filter.
When Should I Replace the Filter?
Filter life varies depending on water quality, household water consumption and the amount of sediment present in the incoming water.
Consider replacing the cartridge when:
-
Water pressure noticeably decreases
-
Water flow becomes restricted
-
The cartridge becomes heavily loaded with sediment
-
The recommended maintenance interval for your filtration system is reached
Water containing large amounts of sediment will generally require more frequent filter replacement.
Regular cartridge replacement helps maintain good water flow and protects downstream filtration components.
Installation
This cartridge is designed to fit compatible 20" x 4.5" Big Blue / Jumbo water filter housings.
Before ordering, check the dimensions and specifications of your existing housing to confirm compatibility.
When replacing the cartridge:
-
Turn off the incoming water supply.
-
Release pressure from the filter housing.
-
Remove the housing sump.
-
Remove and dispose of the used cartridge.
-
Clean the housing as required.
-
Check and correctly position the housing O-ring.
-
Insert the new Aqua Blue H2O cartridge.
-
Reassemble the housing.
-
Slowly restore the water supply and check for leaks.
-
Flush the new filter as appropriate for your filtration system.

Important
This is a sediment filtration cartridge primarily designed for the reduction of suspended particulate matter.
Sediment filtration alone should not be represented as removing dissolved chemicals, microorganisms or other specific contaminants unless the complete filtration system has been independently tested and certified for those claims.
For drinking-water applications requiring additional contaminant reduction, use the appropriate additional filtration stages according to your water quality and treatment requirements.
Need Help Choosing the Right Micron?
Choosing between 1, 5, 10 and 20 micron sediment filters depends on your incoming water quality, required flow rate and filtration system.
For general whole-house sediment filtration, 10 micron is a popular all-round option, while finer cartridges can be selected where smaller particulate filtration is required.
Choose Aqua Blue H2O for dependable replacement water filtration cartridges designed for residential and commercial filtration systems.
