20" Jumbo Polyspun Filter 1 - 5 Micron

Made from layered polypropylene fibres, they trap dirt as water passes through, giving you cleaner water at every tap without slowing your flow.

Available in 1 micron (fine filtration) and 5 micron (general purpose) for both 10" and 20" big jumbo housings.

An economical, first or second stage option whole house filtration.

The DLM Wallace polyspun cartridges are made from fused and intertwined polypropylene fibres. No chemicals or glue is used in construction.

Fine fibres handle efficient particle removal while coarser fibres give the cartridge structural strength. By varying fibre size and density through the cartridge, a true depth filtration gradient is created, capturing particles of different sizes as water passes through.

5 micron — first stage. This is your workhorse pre-filter, catching the bulk of sediment, silt and rust before it reaches anything downstream (carbon block, UV, appliances, etc.).

1 micron — second stage / polishing. Use this after a coarser pre-filter (or after the 5 micron) to catch finer particles that get through the first stage. Running 1 micron as a lone first-stage filter on heavily sedimented water (especially tank/bore supply) will clog it fast and shorten its life significantly.

So for a typical two-cartridge setup: 5 micron polyspun → CTO carbon, or for a three-stage setup: 5 micron polyspun (1st) → 1 micron polyspun or pleated (2nd) → CTO (3rd).

What's the difference between 1 micron and 5 micron polyspun filters?

1 micron captures finer particles for a higher level of sediment removal, typically used as a polishing stage. 5 micron is a general-purpose rating suited to most residential sediment filtration as a first stage.

Do these fit standard (non-jumbo) housings?

These are sized specifically for big 10" and 20" jumbo white housings (Big Blue style), which have a larger diameter than standard housings.

Can a polyspun filter be washed and reused?

No, polyspun cartridges are disposable depth filters. For a washable, reusable option, see our pleated filter cartridges.

What's the difference between polyspun and pleated filters?

Polyspun cartridges are economical, disposable depth filters made from polypropylene fibre. Pleated cartridges use polyester/cellulose media, are washable and reusable, and have a higher dirt-holding capacity before needing cleaning.
