A 20 micron pleated filter cartridge is a coarse process-prefiltration option in the PP and glass fiber families. Its purpose is to control a defined suspended-particle fraction before more sensitive treatment or equipment, where verified retention is sufficient.
For a staged filter train, compare 20 µm with the load seen by the downstream cartridge. A coarse stage is useful only if it removes enough of the relevant feed distribution to justify its added housing, pressure drop and replacement cost.
For a replacement project, confirm whether the original 20 µm rating was nominal or absolute and obtain the corresponding efficiency. A matching nominal length and micron number do not establish hydraulic or retention equivalence.
This is a cross-material selection guide. The linked family pages are the catalog references, not substitutes for a confirmed grade-specific data sheet. Listed family information does not establish that every combination of dimensions, seals and rating is available.
| Material / request | Catalog status | Selection question |
|---|---|---|
| PP | Exact 20 µm grade listed on the detailed family page | Polypropylene; evaluate for compatible water and process liquids. |
| Glass Fiber | Exact 20 µm grade listed on the detailed family page | Confirm the multilayer media, support construction and approved operating conditions. |
For the existing polypropylene-specific product guide, see 20 micron PP pleated filter cartridge. That page addresses the PP construction; this page compares material and process-selection choices.
20 µm is numerically finer. INCE lists 20 µm in the detailed PP and glass fiber series, while 25 µm requires configuration confirmation in this guide. Do not substitute one for the other without checking the process tolerance and verified retention.
Nearby selection guides: 10 µm · 25 µm. Compare equivalent efficiency definitions and cartridge dimensions before changing grade.
| Required rating | 20 µm; state nominal/absolute definition and required retention efficiency. |
|---|---|
| Availability | Listed material families above; confirm the exact orderable combination. |
| Dimensions and interface | Confirm actual length, OD, ID, end-cap drawing and gasket arrangement against the existing housing. |
| Fluid and hydraulics | Provide fluid composition, concentration, viscosity at temperature, flow and allowable clean differential pressure. |
| Operating limits | Obtain configuration-specific temperature, pressure and change-out limits. Limits cannot be inferred from the micron number. |
| Documents | Request a grade-specific data sheet, retention method and any product-contact or validation records required for the application. |
Collect feed and downstream particle measurements during a trial. Ask for the exact media grade, area, end-cap arrangement and verified pressure limits, and check that the coarse stage does not become the hydraulic bottleneck.
No grade-specific flow rate, retention percentage, service life, certification or microbial-validation result is asserted by this guide. Those values must come from documentation for the ordered configuration.

The number alone does not say. Request the retention efficiency, challenge conditions and test method for the exact grade. Do not assume a universal efficiency percentage from the word nominal or absolute.
Match the actual overall length, outside and inside diameters, end-cap interface and seal arrangement against the housing drawing. A matching micron rating or nominal length does not establish fit.
No. Particle-rating information alone does not establish sterilizing performance or removal of dissolved salts and chemicals. Microbial claims need product-specific evidence and process validation; dissolved contaminants require an appropriate treatment process.
Send the required rating and efficiency, liquid and concentration, flow, viscosity, temperature, pressure, particle load, cartridge dimensions, end-cap drawing, seals, quantity and required documentation. Ask INCE filtration to confirm the exact configuration before purchase.
