20" Jumbo 5 Micron Polyspun Water Filter Cartridge

Get fine sediment filtration with high water flow using a 20" Jumbo 5 micron polyspun water filter cartridge.

The larger 20" Jumbo format provides more filter media for higher-flow water systems, while the polyspun polypropylene construction provides depth filtration to capture fine suspended particles throughout the cartridge.

Choose Standard Waimana for dependable 5 micron filtration at up to 90 L/min, or Premium Davey Microlene for higher-flow performance at up to 156 L/min.

Product Options

Standard — Waimana 20PP05

The Waimana 20PP05 provides fine sediment filtration for larger residential and higher-flow water systems.

Its food-grade polypropylene polyspun media filters down to 5 micron while providing a rated flow of up to 90 L/min.

The 20" Jumbo format provides a large volume of depth-filter media, helping capture fine suspended particles while maintaining strong water flow.

Choose Standard when you want dependable 5 micron sediment filtration and 90 L/min provides enough flow for your application.

Premium — Davey Microlene 5PS20J

The Davey Microlene 5PS20J combines fine 5 micron filtration with significantly higher flow capacity.

Its polypropylene spun-melt construction consists of thousands of interlocked, thermally bonded fibres. This helps keep the filtration structure stable as water flow and pressure change while providing clean filtration using an all-polypropylene construction.

The Premium Davey provides:

• 156 L/min rated flow
• 5 micron filtration
• Food-grade polypropylene construction
• Thermally bonded fibre structure
• Maximum operating temperature of 63°C
• High-flow fine filtration for more demanding water systems

Why Choose This Water Filter Cartridge?

• 5 micron sediment filtration — captures fine suspended particles from your water supply.
• 20" Jumbo format — provides greater filter capacity for larger and higher-flow water systems.
• Polyspun depth filtration — captures sediment throughout the depth of the cartridge media.
• 90 L/min Standard option — strong flow for whole-house fine sediment filtration.
• 156 L/min Premium option — significantly greater flow capacity for higher-demand systems.
• Food-grade polypropylene media — well suited to potable-water filtration.
• Excellent second-stage filtration — works particularly well after a coarser sediment cartridge.

How It Works

Polyspun cartridges use a depth-filtration structure made from layers of polypropylene fibres.

As water passes through the cartridge, suspended particles are captured at different depths throughout the filter media rather than relying only on the outside surface.

The 5 micron rating provides fine sediment filtration while maintaining more flow than a finer 1 micron cartridge.

Combined with the larger 20" Jumbo format, this makes it a strong choice for whole-house systems where both fine particle removal and high water flow are important.

The Premium Davey cartridge uses thousands of interlocked, thermally bonded fibres, helping maintain the structure of the filtration media as flow and pressure change.

Best Suited For

This 20" Jumbo 5 micron water filter cartridge is well suited to:

• Whole-house water filtration
• Larger residential water systems
• Fine sediment removal
• Drinking water filtration
• Tank water systems
• Rainwater systems
• Bore and groundwater systems
• Sediment polishing
• High-flow sediment filtration
• Second-stage filtration after a coarser cartridge
• Prefiltration ahead of finer treatment stages
• Prefiltration ahead of reverse osmosis
• Commercial water filtration
• Beverage and food-industry applications
• Laboratory and high-purity water applications

For multi-stage filtration systems, a 5 micron cartridge works particularly well after a coarser sediment filter. The first stage captures larger sediment, leaving the 5 micron cartridge to focus on finer particles.

Key Specifications

Standard vs Premium — Which Should I Choose?

Choose Standard Waimana if you want:

• Reliable 5 micron sediment filtration
• 90 L/min rated flow
• Food-grade polypropylene media
• Strong whole-house filtration capacity
• A practical 20" Jumbo cartridge for potable cold water
• Fine filtration at a lower price point

For many whole-house systems, 90 L/min provides plenty of flow, making Standard a strong all-round choice.

Choose Premium Davey if you want:

• Higher 156 L/min rated flow
• Fine 5 micron sediment filtration
• Thermally bonded polypropylene fibres
• Maximum operating temperature of 63°C
• Greater flow capacity for larger or higher-demand systems
• A cartridge suited to drinking water, beverage, food, laboratory and other low-contamination applications

The main reason to move to Premium is higher flow capacity while maintaining the same 5 micron filtration level.

Installation

This cartridge is designed for use in a compatible 20" Jumbo water filter housing.

To replace the cartridge:

1. Turn off the water supply.
2. Release pressure from the filter housing.
3. Remove the filter housing sump.
4. Remove the existing cartridge.
5. Clean the housing if required.
6. Check that the O-ring is clean and seated correctly.
7. Insert the new cartridge.
8. Reassemble the housing.
9. Slowly restore water pressure.
10. Check the housing for leaks.

Always follow the installation instructions supplied with your filter housing and water filtration system.

Maintenance

Polyspun cartridges are designed as replaceable depth filters.

Cartridge life depends on water quality, sediment loading and water usage. As sediment builds up throughout the media, water flow will gradually reduce, indicating that replacement may be required.

Standard — Waimana

Replace around every 12 months, or sooner if water quality or flow noticeably reduces.

Premium — Davey Microlene

Replace when the cartridge becomes loaded with sediment or flow performance declines.

Davey recommends replacement every 12 months, with actual service life depending on the level of suspended solids in the water.

Frequently Asked Questions

What does 5 micron mean?

A 5 micron water filter cartridge captures fine suspended particles from your water supply.

It provides finer filtration than a 20 micron cartridge while maintaining more flow than a 1 micron cartridge, making 5 micron a versatile choice for whole-house sediment filtration.

What's the difference between Standard and Premium?

The biggest difference is flow capacity.

The Standard Waimana provides up to 90 L/min, while the Premium Davey is rated at 156 L/min.

Both provide 5 micron polypropylene depth filtration.

Which option should I choose?

Choose Standard Waimana for general 5 micron whole-house filtration where 90 L/min provides enough flow.

Choose Premium Davey when your system has higher water demand and you want the additional flow capacity of its 156 L/min rating.

What is the flow rate?

Standard Waimana: 90 L/min

Premium Davey Microlene: 156 L/min

Actual system flow will also depend on water pressure, plumbing, filter housing and sediment loading.

Can I clean and reuse these cartridges?

No. Polyspun cartridges are designed as replaceable depth filters.

Once the cartridge becomes loaded with sediment and water flow noticeably reduces, replace it with a new cartridge.

How often should I replace the cartridge?

A good guide is every 12 months, or sooner where sediment loading causes a noticeable reduction in water flow or filtration performance.

Is 5 micron good for whole-house filtration?

Yes. 5 micron provides a useful balance between fine sediment removal and water flow, making it a strong option for whole-house filtration.

Can I use a 5 micron cartridge after a 20 micron filter?

Yes. This is an effective staged-filtration setup.

The 20 micron cartridge captures larger sediment first, while the 5 micron cartridge provides finer filtration downstream.

Should I choose 1 micron or 5 micron?

Choose 5 micron when you want a good balance between fine sediment removal and water flow.

Choose 1 micron when finer particle capture is the priority.

For multi-stage systems, the right micron sequence depends on your source water and the treatment stages that follow.

Why choose a 20" Jumbo instead of a 10" Jumbo cartridge?

The larger 20" Jumbo format provides more filter media and greater flow capacity, making it better suited to larger homes and higher-demand water systems.

Will this fit a 20" Jumbo housing?

Yes. This cartridge is designed for a compatible 20" Jumbo water filter housing.
