A 0.22 micron pleated filter cartridge is a fine filtration grade that must be specified together with membrane material, retention evidence and service conditions. A cartridge carrying a 0.22 µm rating is not automatically a validated sterilizing-grade filter.
For a water or process-liquid polishing stage, compare PP, PTFE or PVDF families that list this exact rating. Where the application requires microbial control, ask for the specific product validation and the operating conditions covered by that validation before selecting a cartridge.
If an existing specification calls for 0.2 µm PES or nylon, do not silently substitute 0.22 µm. The detailed PES and nylon catalog pages list 0.2 µm; confirm whether a qualified 0.22 µm version exists or whether the process can accept the documented alternative.
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 0.22 µm grade listed on the detailed family page | Polypropylene; evaluate for compatible water and process liquids. |
| PTFE | Exact 0.22 µm grade listed on the detailed family page | Confirm hydrophilic or hydrophobic configuration and complete fluid compatibility. |
| PVDF | Exact 0.22 µm grade listed on the detailed family page | Polyvinylidene fluoride membrane; confirm the selected grade and operating envelope. |
For the existing polypropylene-specific product guide, see 0.22 micron PP pleated filter cartridge. That page addresses the PP construction; this page compares material and process-selection choices.
Catalog precision: the detailed PES and nylon pages list 0.2 µm. Do not treat 0.2 and 0.22 µm as a confirmed interchangeable product specification.
0.22 µm states a finer grade than 0.45 µm, but a pore-size comparison is not a microbial validation. Select a final filter against the process acceptance criteria and qualified product data, not a generalized sterile-filter claim.
Nearby selection guides: 0.1 µm · 0.45 µm. Compare equivalent efficiency definitions and cartridge dimensions before changing grade.
| Required rating | 0.22 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 whether retention data is particulate or microbial, which challenge method was used and which temperature, pressure, fluid and exposure limits apply. If the process needs integrity testing, obtain the product-specific method and acceptance criteria.
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.
