A 5 micron pleated filter cartridge is a process-water and compatible-liquid prefiltration option. It can be evaluated ahead of finer treatment, but its suitability for a particular RO system or other equipment depends on the equipment supplier’s requirements and documented cartridge performance.
For RO pretreatment, obtain the membrane-system supplier’s filter specification and review the feed-water condition. A 5 µm cartridge does not independently control dissolved salts or establish acceptable biological fouling risk, and it cannot replace the rest of the pretreatment design.
For recirculating process water, evaluate PP or glass fiber at the actual circuit flow and operating temperature. Check whether the housing permits adequate cartridge area and whether bypass through seals could undermine the selected retention grade.
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 5 µm grade listed on the detailed family page | Polypropylene; evaluate for compatible water and process liquids. |
| Glass Fiber | Exact 5 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 5 micron PP pleated filter cartridge. That page addresses the PP construction; this page compares material and process-selection choices.
5 µm is the finer stated rating. Evaluate 10 µm for a coarse upstream duty only when its retention meets the downstream requirement. For a sensitive process, use documented efficiency rather than assuming either label is sufficient.
Nearby selection guides: 3 µm · 10 µm. Compare equivalent efficiency definitions and cartridge dimensions before changing grade.
| Required rating | 5 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. |
Ask for the grade-specific retention curve, clean pressure-drop curve and approved change-out limit. Record pressure before and after the housing during commissioning and confirm the seal arrangement against the housing drawing.
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.
