A 0.65 micron pleated filter cartridge is an intermediate fine grade between the 0.45 and 1 micron topics in this selection guide. The detailed INCE PES, nylon and PVDF family pages list 0.65 µm. The existing PP standard-rating list does not establish a 0.65 µm PP option.
Evaluate this grade when 0.45 µm may be finer than the process needs but the next coarser candidate does not meet the particle specification. Compare the actual efficiency curves; a nominal rating on one material should not be treated as equivalent to an absolute rating on another.
For aqueous polishing, compare the documented wetting and product-contact properties of PES and PVDF. For a nylon candidate, verify chemical exposure and the required product recovery. A shared 0.65 µm label does not eliminate these material-selection questions.
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 |
|---|---|---|
| PES | Exact 0.65 µm grade listed on the detailed family page | Polyethersulfone membrane; evaluate wetting and product-contact requirements. |
| Nylon | Exact 0.65 µm grade listed on the detailed family page | Confirm the exact nylon grade and compatibility of the full cartridge. |
| PVDF | Exact 0.65 µm grade listed on the detailed family page | Polyvinylidene fluoride membrane; confirm the selected grade and operating envelope. |
0.45 µm is the finer stated number. Compare tested retention, throughput and acceptable pressure drop to determine whether that additional fineness is needed. Confirm the available neighboring grade for the selected material; nylon may list 0.8 or 1.2 µm instead of 1 µm.
Nearby selection guides: 0.45 µm · 1 µm. Compare equivalent efficiency definitions and cartridge dimensions before changing grade.
| Required rating | 0.65 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. |
Request confirmation of the 0.65 µm grade, membrane identity, retention method and housing interface. Trial the selected family with the real liquid and record both quality and pressure drop before standardizing a replacement.
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.
