A washable, reusable pleated sediment water filter cartridge for 20" Jumbo (Big Blue) housings — ideal for higher-capacity tank, bore and river water filtration.

The Pentair 20" Jumbo Polypleated Sediment Filter is made from durable pleated polyester and provides a large filtration surface area for capturing suspended sediment while maintaining good water flow.

Its larger 20" Jumbo format provides greater sediment-holding capacity and longer intervals between cleaning than the 10" version, making it particularly well suited to higher-flow systems and water supplies with heavier sediment loading.

When dirty, simply remove, rinse and reuse the cartridge.

Choose from 1, 5, 20 or 50 micron filtration using the dropdown above.

Choose Your Micron Rating

Micron Rating Filtration Level Best Suited To
1 Micron Fine Final-stage filtration, protecting UV lamps and sensitive downstream equipment
5 Micron Fine-medium Second or final-stage sediment filtration for fine silt and small particles
20 Micron Medium First-stage prefiltration on bore, river or tank water with moderate sediment
50 Micron Coarse First-stage prefiltration on high-sediment bore, river and surface water

Which Micron Rating Should I Choose?

For multi-stage filtration, use coarser cartridges before finer cartridges.

A common two-stage configuration is:

20 or 50 Micron → 1 or 5 Micron

This allows the first cartridge to capture larger sediment before the water reaches the finer second-stage filter.

For particularly sediment-heavy supplies, the 50 micron option can make an excellent first-stage prefilter.

Why Choose a 20" Jumbo Pleated Filter?

The combination of 20" cartridge length, 4.5" Jumbo diameter and pleated media provides substantial filtration surface area.

More filtration area means more space to capture sediment before flow becomes restricted.

Compared with the 10" version, the 20" cartridge provides higher dirt capacity and longer service intervals between cleaning, making it an excellent option for larger whole-house systems and demanding water supplies.

Washable & Reusable

The pleated polyester media is designed to be washed and reused.

When sediment builds up or water flow begins to reduce:

  1. Turn off the water supply.
  2. Release pressure from the housing.
  3. Remove the housing sump.
  4. Remove the cartridge.
  5. Rinse accumulated sediment from the pleated media using clean water.
  6. Reinstall the cartridge.
  7. Reassemble the housing and restore the water supply.
  8. Check for leaks.

Cleaning frequency depends on the quality of your incoming water and the micron rating selected.

Coarser particles such as sand are generally easier to rinse away, while very fine silt can become embedded within the pleats over time.

Replace the cartridge once cleaning no longer restores adequate flow or if the polyester media becomes damaged or degraded.

Best Suited For

The Pentair 20" Jumbo Polypleated Filter is well suited to:

  • Whole-house water filtration
  • Rainwater tanks
  • Bore water
  • River water
  • Surface water
  • Higher-flow filtration systems
  • High-sediment water supplies
  • First-stage sediment filtration
  • Fine second-stage sediment filtration
  • UV system prefiltration
  • Protecting downstream equipment
  • Multi-stage water treatment systems

Using It Before a UV System

Good sediment filtration helps prepare water before it reaches downstream treatment equipment such as a UV system.

For finer final-stage sediment filtration, choose a 1 or 5 micron cartridge.

Where incoming water contains heavier sediment, install a coarser cartridge upstream.

For example:

20 Micron Pleated → 1 Micron Pleated → UV

or

50 Micron Pleated → 5 Micron Pleated → UV

This progressive approach allows the first cartridge to capture larger particles before the finer cartridge provides final sediment filtration.

Frequently Asked Questions

Is this cartridge washable and reusable?

Yes.

Remove the cartridge when dirty, rinse accumulated sediment from the pleated polyester media and reinstall it.

Continue cleaning and reusing the cartridge until washing no longer restores adequate flow or the media becomes degraded or damaged.

What micron ratings can I choose?

The available options are:

  • 1 Micron
  • 5 Micron
  • 20 Micron
  • 50 Micron

Select your required micron rating from the dropdown above.

Which micron rating is best?

For first-stage filtration of heavier sediment, 20 or 50 micron is generally the better choice.

For finer second or final-stage filtration, choose 1 or 5 micron.

If using multiple housings, install the coarser filter first and progressively move to finer filtration downstream.

What is the advantage of the 20" cartridge?

The 20" Jumbo cartridge provides more filtration area and sediment-holding capacity than the 10" version.

This makes it particularly useful for higher-flow systems, whole-house filtration and water supplies with heavier sediment loading, while also extending the interval between cleanings.

Is it suitable for bore water?

Yes.

For bore water containing substantial sediment, consider starting with a 20 or 50 micron cartridge before moving to finer filtration downstream.

Can I use it for rainwater?

Yes. The cartridge is well suited to sediment filtration on rainwater and tank-water systems.

Can it be used with river water?

Yes, as a sediment filtration stage.

River and surface-water quality varies considerably and may require multiple filtration and treatment stages depending on the intended use.

Will it fit my 20" Big Blue housing?

Yes, provided your housing accepts standard 20" Jumbo / Big Blue cartridges.

The cartridge is approximately 500mm long and 4.5" diameter.

Will it fit a 10" Jumbo housing?

No. This listing is specifically for the 20" Jumbo cartridge.

For a 10" Jumbo housing, select the corresponding Pentair 10" Jumbo Polypleated Sediment Water Filter Cartridge.

Can I use two of these in a multi-stage system?

Yes.

For example:

50 Micron → 5 Micron

or

20 Micron → 1 Micron

This allows the first cartridge to handle larger sediment while the second provides finer filtration.
