20" Jumbo 20 Micron Pleated Water Filter Cartridge

Keep sediment under control while maintaining high water flow through your filtration system.

This 20" Jumbo 20 micron pleated water filter cartridge is designed to capture sediment and suspended particles from your water supply while providing the large filtration area needed for higher-flow applications.

The larger 20" Jumbo format gives you substantially more filtration capacity than a 10" cartridge, making it well suited to whole-house systems, larger homes and applications with higher water demand.

Choose Standard Waimana for reliable filtration at up to 110 L/min, or Premium Davey Microlene for high-flow performance at up to 188 L/min.

Both cartridges are cleanable and reusable, helping extend cartridge life and reduce replacement frequency.

Product Options

Standard — Waimana 20PL20

A practical high-flow option for everyday sediment filtration.

The Waimana 20PL20 uses food-grade pleated polypropylene media to capture sediment from potable cold water while maintaining a rated flow of up to 110 L/min.

Its 20" Jumbo size provides a large filtration surface area, making it a strong option for whole-house systems and other applications where greater flow and filtration capacity are required.

The cartridge can be cleaned and reused, helping extend its useful service life.

Choose Standard when you want dependable 20 micron sediment filtration with plenty of flow for most residential and general-purpose applications.

Premium — Davey Microlene 20PP20J

The Davey Microlene 20PP20J is designed for applications where maximum flow and strong sediment-holding performance matter.

Its high-surface-area polyester pleated media provides:

• 188 L/min rated flow
• High dirt-holding ability
• Low pressure drop
• Cleanable and reusable filtration
• Strong performance in high-demand systems
• Good performance in lower-pressure water supplies

The combination of a 20" Jumbo format and 188 L/min rated flow makes the Premium Davey a strong choice for systems with greater water demand.

Why Choose This Water Filter Cartridge?

• 20 micron sediment filtration — captures suspended sediment and particulate matter from your water supply.
• 20" Jumbo format — provides a large filtration area for higher-flow systems.
• Pleated filter media — maximises filtration surface area inside the cartridge.
• Cleanable and reusable — both options can be cleaned to extend cartridge life.
• 110 L/min Standard option — strong flow capacity for whole-house and general filtration.
• 188 L/min Premium option — considerably more flow for higher-demand systems.
• High dirt-holding capacity — the large pleated surface area gives sediment more area to collect.
• Two performance levels — choose the cartridge that matches your system rather than paying for capacity you don't need.

How It Works

Water passes through the pleated filter media, where sediment and suspended particles are captured before the water continues through your filtration system.

The 20 micron rating makes this cartridge ideal for general sediment filtration and as a first-stage filter ahead of finer filtration.

Pleating allows a large amount of filter media to fit within the cartridge. Combined with the 20" Jumbo format, this provides plenty of surface area for sediment collection while helping maintain strong water flow.

The Premium Davey design is specifically built around high flow, high dirt-holding ability and low pressure drop, making it particularly useful where system performance needs to be maintained under greater demand.

Best Suited For

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

• Whole-house water filtration
• Larger residential water systems
• Tank water systems
• Rainwater systems
• Domestic water filtration
• Drinking water filtration
• High-flow sediment filtration
• Sediment prefiltration
• Prefiltration before finer cartridges
• Prefiltration ahead of reverse osmosis
• Commercial water filtration
• Light industrial applications

The Premium Davey cartridge is also suited to beverage production, mineral-water bottling, laboratory use and food-industry filtration. Its pleated design is particularly useful in lower-pressure applications such as roof-water and header-tank systems.

Key Specifications

Standard vs Premium — Which Should I Choose?

Choose Standard Waimana if you want:

• Reliable 20 micron sediment filtration
• 110 L/min rated flow
• Food-grade pleated polypropylene media
• A cleanable and reusable cartridge
• Strong whole-house filtration performance
• A cost-effective 20" Jumbo replacement cartridge

For many whole-house systems, 110 L/min provides plenty of flow, making Standard a strong all-round option.

Choose Premium Davey if you want:

• Higher 188 L/min rated flow
• Greater documented flow capacity
• High dirt-holding ability
• Low pressure drop
• Cleanable and reusable polyester pleated media
• Stronger performance in high-demand systems
• Maximum operating temperature of 52°C
• Good performance in lower-pressure applications

The main reason to move to Premium is flow performance.

Both cartridges provide reusable 20 micron pleated sediment filtration, but the Davey increases rated flow from 110 L/min to 188 L/min.

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

Cartridge life depends on water quality, sediment loading and water usage.

Clean the cartridge when sediment build-up begins to reduce water flow, and replace it when cleaning no longer restores satisfactory performance.

Standard — Waimana

The Waimana cartridge can be cleaned and reused.

For ongoing performance, replace the cartridge around every 12 months or sooner if water quality or flow noticeably reduces.

Its operating range of 5–45°C and 1–4 bar makes it well suited to potable cold-water filtration systems.

Premium — Davey Microlene

The Davey cartridge can be cleaned under a tap or with gentle hosing when sediment build-up begins to restrict flow.

Cleaning is recommended when flow becomes too low or head loss reaches 15 psi. The polyester pleated cartridge can be cleaned several times before replacement is required.

Frequently Asked Questions

What does 20 micron mean?

A 20 micron water filter cartridge is designed to capture sediment and suspended particles from the water as it passes through the filter media.

It works well as a general sediment filter or first-stage cartridge before finer filtration.

What's the difference between Standard and Premium?

The biggest difference is flow rate.

The Standard Waimana is rated at 110 L/min, while the Premium Davey is rated at 188 L/min.

Both cartridges use pleated media and are cleanable and reusable.

Which option should I choose?

Choose Standard Waimana for whole-house and general sediment filtration where 110 L/min provides enough capacity.

Choose Premium Davey when you need considerably more flow, lower pressure drop or greater performance in a higher-demand system.

What is the flow rate?

Standard Waimana: 110 L/min

Premium Davey Microlene: 188 L/min

Actual system flow will also depend on water pressure, plumbing, filter housing and how much sediment has accumulated in the cartridge.

Can I clean and reuse these cartridges?

Yes. Both options are cleanable and reusable.

Cleaning accumulated sediment helps restore water flow and can extend the useful life of the cartridge.

How often should I replace the Waimana cartridge?

A good replacement interval is around 12 months, or sooner where water quality, sediment loading or reduced flow indicates a replacement is needed.

Can I use this filter for rainwater?

Yes. A 20 micron pleated cartridge is well suited to sediment filtration in water systems where suspended particles need to be captured.

The Premium Davey cartridge is particularly useful in roof-water and lower-pressure applications.

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

The larger 20" Jumbo format provides more filtration surface area and substantially greater flow capacity.

For comparison, the 20" options here provide rated flows of 110 L/min and 188 L/min, making them better suited to larger homes and higher-demand water systems.

Will this fit a 20" Jumbo housing?

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