Choosing between these two filtration separation products comes down to the job your system is built for. One is a bulk pack of sediment cartridges made for Big Blue-style filter housings. The other is a process filter for specific equipment. The right match depends on the housing and the fitting, not just the price. Their list prices sit at $152.45 and $45.00, a $107.45 spread that mirrors how different these two products are.
Quick verdict
If you want a bulk supply of sediment cartridges to have on hand, the Membrane Solutions bundle is the practical choice. If your process equipment needs a replacement filter, the CUNO 13136-01 is the one built for that role.

|---|---|---|---|---|
| Membrane Solutions 20-Pack String Wound Sediment Filter | $152.45 | 10" x 4.5", 1/5/10 micron, NSF Standard 42, 30,000-gal rated capacity | Big Blue-style housings needing multiple sediment cartridges | |

Where each product wins
- The Membrane Solutions bundle wins when you are stocking up for ongoing sediment filtration and want a single order to cover many filter changes.
- The CUNO 13136-01 wins when you need a process-line replacement with a specific connector and rating.
Neither filter is a substitute for the other, so the decision comes down to the system you are maintaining.
Product notes
Membrane Solutions 20-Pack String Wound Sediment Filter
String-wound polypropylene is a good match for sediment-heavy water, and this bundle is meant for that task. It carries an NSF certification against Standard 42 for materials, and a rated capacity of 30,000 gallons, which gives you a sense of the duty it is designed for. The limitation is the quantity: you are buying 20 cartridges at once, so this only makes sense if you actually go through sediment filters on a regular schedule. For someone who changes one cartridge every year or two, the bulk format is excessive. If you service multiple housings or replace filters often, the bulk size is a genuine advantage.
CUNO DDS Filter 13136-01 (20-0080 Cartridge) 250PSI 3/8NPT
This is a process filter for a defined application. It is rated for 250 PSI with a 3/8 NPT connection, and the cartridge is included, so it suits equipment that needs that specific pressure fit. The flip side is that the fit is narrow. Unless your system is built around this filter's specification, it isn't a universal replacement. It solves a real problem for the right setup, but the connector and pressure rating have to match. For operators who maintain that type of system, the single-unit format is easy to keep on hand.
Final choice by use case
For a standard sediment cartridge housing, the Membrane Solutions bundle is the choice if you want multiple replacements on hand. For process equipment that matches the CUNO's connector and rating, the CUNO 13136-01 is the one. If your system doesn't match the CUNO's specification, it won't work as a substitute for a sediment cartridge; and if you don't need a bulk supply, the bundle is more than you need.
