20" Jumbo 1 Micron Polyspun Water Filter Cartridge

Get fine 1 micron sediment filtration with high water flow using a 20" Jumbo polyspun water filter cartridge.

The larger 20" Jumbo format provides significantly 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 1 micron filtration at up to 90 L/min, or Premium Davey Microlene for higher-flow performance at up to 152 L/min and a documented >99% Cryptosporidium cyst removal rating for the 1 micron cartridge.

Product Options

Standard — Waimana 20PP01

The Waimana 20PP01 provides fine sediment filtration for larger residential and higher-flow water systems.

Its food-grade polypropylene polyspun media filters down to 1 micron while providing a rated flow of up to 90 L/min.

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

Choose Standard when you want dependable 1 micron filtration and 90 L/min provides enough flow for your application.

Premium — Davey Microlene 1PS20J

The Davey Microlene 1PS20J combines fine 1 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:

• 152 L/min rated flow
• 1 micron filtration
• >99% Cryptosporidium cyst removal rating
• 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?

• Fine 1 micron filtration — captures very fine suspended particles from the 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.
• 152 L/min Premium option — significantly greater flow capacity for higher-demand systems.
• Food-grade polypropylene media — well suited to potable-water filtration.
• Premium Cryptosporidium performance — the Davey 1 micron cartridge carries a >99% cyst removal rating.

How It Works

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

As water passes through the cartridge, fine suspended particles are captured at different depths throughout the filter media.

The combination of 1 micron filtration and a 20" Jumbo format makes this cartridge particularly useful where fine particle removal is required without unnecessarily limiting the flow available to a larger water system.

The 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 1 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
• Final sediment polishing
• High-flow fine filtration
• 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 systems using multiple filtration stages, a 1 micron polyspun cartridge works particularly well after a coarser sediment filter, allowing larger particles to be captured first and leaving this cartridge to handle the finer sediment.

Key Specifications

Standard vs Premium — Which Should I Choose?

Choose Standard Waimana if you want:

• Reliable 1 micron fine 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 applications, 90 L/min provides plenty of flow, making Standard a strong all-round choice.

Choose Premium Davey if you want:

• Higher 152 L/min rated flow
• Fine 1 micron sediment filtration
• >99% Cryptosporidium cyst removal rating
• 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 Premium advantage is the combination of very fine filtration and substantially higher flow capacity.

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 1 micron mean?

A 1 micron water filter cartridge provides fine sediment filtration, capturing very small suspended particles from your water supply.

It provides considerably finer filtration than 5, 20 or 50 micron cartridges and works particularly well as a final sediment-polishing stage.

What's the difference between Standard and Premium?

The main differences are flow capacity and documented filtration performance.

The Standard Waimana provides up to 90 L/min, while the Premium Davey is rated at 152 L/min.

The Davey 1 micron cartridge also carries a >99% Cryptosporidium cyst removal rating.

Which option should I choose?

Choose Standard Waimana for general 1 micron whole-house filtration where 90 L/min provides enough flow.

Choose Premium Davey when your system has higher water demand or you want the additional documented Cryptosporidium cyst removal performance.

What is the flow rate?

Standard Waimana: 90 L/min

Premium Davey Microlene: 152 L/min

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

Does the Davey cartridge remove Cryptosporidium?

The 1 micron Davey Microlene polyspun cartridge has a Cryptosporidium cyst removal rating greater than 99%.

Can I clean and reuse these cartridges?

No. Polyspun cartridges are replaceable depth filters.

Once the cartridge becomes loaded with sediment and flow performance drops, it should be replaced.

How often should I replace the cartridge?

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

Can I use a 1 micron cartridge after a 20 micron filter?

Yes. This is an effective staged-filtration setup.

The coarser filter captures larger sediment first, while the 1 micron cartridge provides the finer polishing stage.

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

The larger 20" Jumbo cartridge 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.
