High Flow Filter Cross-Reference Matrix
A family or brand match is the first step and is not a substitute for part-level approval. Use the candidate selector, family comparison and quote-readiness estimator to prepare the review. The filter cross reference list connects known originals to the ECOFILTRONE series for candidate family and physical fit evaluation against the cited original-family fields.
| Original family | Candidate ECOFILTRONE family | Physical match points | Approval boundary |
|---|---|---|---|
| Pall HFU620 / HFU640 / HFU660 | HFA Series | 154 mm OD; 20/40/60 in; single O-ring; inside-to-out flow | Confirm full part number, media, seal and rating basis |
| Parker Fulflo MegaFlow | HFA Series | 154 mm OD; 20/40/60 in; inside-to-out flow | Confirm installed housing and original specification |
| 3M CUNO 700 Series | HFM Series | 159 or 166 mm OD; 40/60 in; outside-to-in flow | Confirm diameter variant, end interface and seal |
| 3M CUNO 740 Series | MHFB Series | 163.5 or 166 mm OD; 40/60 in; twist-to-lock interface | Confirm locking geometry and operating conditions |
| Pentair Aqualine High Flow | HFP Series | 172 mm OD; 40/60 in | Confirm model-specific construction and rating |
“A cross-reference line indicates where to begin; approval comes from the fit and duty data attached to the exact part.”— ECOFILTRONE application review rule
PROCESS
Two-stage approval
The first stage evaluates the family, outside diameter, length, connection, seal and flow direction in the installed cartridge filter equipment. The second stage covers process fluid, filter media, efficiency basis, flow, temperature, pressure and required filtration performance. For ECOFILTRONE™, the listed families are not interchangeable by name alone and are not a substitute for part-level approval: treating a family label as approval is the wrong call, and the closest-looking size is not always the right call because mismatch risk remains when a 154 mm cartridge uses a different seal or operating duty.

Physical Fit and Operating Compatibility
A cartridge that fits in a housing can still perform differently due to variations in media, seal compound, rating definition, or process conditions. A shared micron rating is not by itself a performance match; verify the nominal or absolute basis, test method and operating conditions instead of assuming that definitions transfer across manufacturers.
ANALYSIS
Why actual-fluid review matters
Published evidence on process filtration cases shows that cartridge swelling or deformation can occur with actual operating conditions and fluids, even if the original specification looks acceptable. Process data helps us to pick a candidate for sampling or trial; a dimensionally similar cartridge is not interchangeable until the application review is performed.
DIMENSIONAL
Physical-fit review
- Original OEM part number and brand family
- Overall length and outer diameter
- End cap, handle and locking geometry
- O-ring or gasket position, profile and material
- Inside-to-outside or outside-to-inside flow
OPERATIONAL
Application review
- Process fluid and cleaning chemicals
- Operating temperature and pressure
- Flow rate, viscosity and differential pressure
- Micron rating definition and required removal efficiency
- Validation, traceability and document requirements
ECOFILTRONE Cartridge Specifications

Verification and Documentation
This specification table outlines the available series envelope. The final values are confirmed on the quotation and model datasheet under the documented review approach. Not all combinations are available for all cartridge elements.
COMPLIANCE
Verification rule
The final inspection verifies the requested dimensions, identification, packaging and documents. Documents are supplied for the specific product and actual certificate holder. A certificate attached to one material, model or legal entity is not applicable to all filter cartridges.
Order-control sequence
- ECOFILTRONE inspection verifies the requested part corresponds to the specified product and operating conditions, and ensures the requested requirements are assigned to the appropriate inspection.
- A specification check is performed by comparing the original part, drawing or sample, to the candidate ECOFILTRONE model.
- The materials of construction are confirmed to be acceptable to the requested conditions.
- The confirmed configuration is tracked during assembly and inspected.
Available after model verification
- Product technical data
- Material certificates
- Applicable compliance documents
- Drawings or specification confirmation
PROCESS FLOW
Replacement Matching Workflow
Incomplete part data creates mismatch risk as a housing fit does not guarantee fit for filtration duty under the cited review criteria. The six-step process for ECOFILTRONE is the same for the sample and the released production configuration.
1
The identifier should be sent. Provide the original part number, brand and series and the housing it was installed in.
2
The physical part data should be sent. Include length, outer diameter, interface, flow direction, seal, or provide a drawing and photos.
3
Define the filtration duty. Indicate fluid, solid, micron target, rating basis, flow, viscosity, temperature and differential pressure.
4
The candidate should be reviewed. We identify the likely family and flag any missing specification that could change fit or performance.
5
Approve a sample or trial. In cases where process sensitivity requires validation of the element chosen for use in actual operating conditions, the customer should validate the sample or trial under those conditions.
6
The order should be released. The confirmed model and quantity move into production and the required documentation, timing, inspection, packing and shipping also move into production.
After-sales engineering support
Post-sales engineering covers installation and compatibility checks, review of differential pressure, service-life, maintenance planning, and troubleshooting. It covers optimization of filtration configuration. Analysis is performed based on customers’ measured data.
Start with the available evidence
Send a drawing or datasheet for review. A readable part number and end-interface photos can be sent to initiate the review.
Application and Project Evidence
High-flow cartridge filtration is used in industrial water and SWRO pretreatment applications, where the wider treatment train and upstream conditions influence the service imposed on the cartridge. When those upstream conditions are omitted, mismatch risk rises; ECOFILTRONE ties the application record to the selected element and specification.
- Industrial water treatment, RO and UF pretreatment, and seawater desalination
- Treatment of waste water, water re-use, power generation, oil and gas.
- Petrochemical, chemical processing, food and beverage, and pharmaceutical service
- Electronics, high-purity water, and other process-filtration applications

KNOWLEDGE BASE
High Flow Filter Cartridge FAQs
How do I cross-reference a high flow filter cartridge?
Start with the original part number and family, then compare length, outside diameter, end interface, seal and flow direction. Complete the review with media, rating basis, fluid, temperature, flow, viscosity and differential-pressure requirements listed in the cited equivalent-selection guide.
What is the difference between a 3M CUNO 700 and 740 replacement interface?
For the listed candidates, the 700 route is the HFM family at 159 or 166 mm OD, while the 740 route is the MHFB family at 163.5 or 166 mm OD with a twist-to-lock interface. CONFIRM THE EXACT ORIGINAL PART NUMBER AND INSTALLED CONNECTION BEFORE PLACING AN ORDER.
Which ECOFILTRONE series is used for a Pall filter alternative?
HFA is the candidate family for Pall HFU620, HFU640 and HFU660 matching. Some common cited selections include 1, 5, 10, 20 and 40 µm, but the exact grade and rating need to be confirmed.
Can I request a sample before a production order?
Yes. A free sample is available with freight paid by the customer; trial orders are accepted, while customized batch orders normally start at 100 pieces.
Are Pall, 3M, CUNO and Parker trademarks owned by ECOFILTRONE?
No. Parker, 3M, CUNO and Pall are referenced brand names. Pall, 3M, CUNO, Parker, Parker Hannifin, Fulflo, MegaFlow, Pentair and Aqualine names are used only to identify replacement targets; ownership remains with the respective brand owners.
Can I select a replacement from the micron rating alone?
No. Micron labels can use different nominal or absolute definitions, removal efficiency, test methods and media construction, and may be subject to different operating conditions.
Which ECOFILTRONE series is used for Parker MegaFlow matching?
HFA is the candidate family for Parker Fulflo MegaFlow, with 154 mm OD, and 20, 40 or 60 inches in length. Final approval verifies the original specification, installed housing, seal, media and the operating duty.
How quickly can ECOFILTRONE quote and ship?
Quotation response is within 24 hours after the required matching information arrives. Stock orders can ship in 4–5 days, custom samples in 7 days and custom production in 14 days after approval.
