Filtration and separation purchases usually fail when the cartridge type doesn't match the system, the pressure rating is wrong, or the pack size doesn't fit the maintenance schedule. The four choices here cover very different jobs: a high-pressure process filter, a multi-cartridge water filter set, a compressed-air particulate filter with an auto drain, and a bulk sediment cartridge set for large-format housings. The right choice depends on whether you're protecting process equipment, a compressed-air line, or a whole-house water system.
Quick take
If you need a filter that matches DDS process equipment, the CUNO DDS Filter 13136-01 is the most targeted pick. For compressed-air lines, the High Flow Industrial Air Filter adds moisture and debris protection. When you want multiple water filter cartridges at once, the Process Filtration P/N 3P879 T15R10A set is a practical replacement buy. For a large-format sediment housing, the string-wound sediment set covers a long replacement cycle.

Product notes
CUNO DDS Filter 13136-01
The CUNO DDS Filter 13136-01 is built for DDS equipment and includes the 20-0080 cartridge. With a 250 PSI rating and a 3/8 NPT connection, it suits a narrow high-pressure process role rather than a general-purpose water line. That specificity is the main reason to pick it if your system is built around DDS components. The trade-off is that you're buying a single filter/cartridge setup, so it handles one service point instead of a multi-cartridge maintenance cycle. At $45.00, it is also the lower-priced entry in this comparison.
Process Filtration P/N 3P879 T15R10A Water Filter
This is a six-filter set carrying the Process Filtration part number 3P879. The T15R10A reference gives you a clear part to order against, and $49.99 covers the whole set. The condition is New - Open box, so the cartridges are described as new but the set may not arrive in factory-sealed packaging. That open-box status is the main limitation to weigh before choosing it as a replacement supply. Country of origin is the United States, which may matter to buyers who prefer domestic sourcing.
High Flow Industrial Air Filter
This filter is aimed at compressed-air lines, not water. It combines 5-micron particulate filtration with an auto drain and a metal bowl, both of which matter when liquid and debris are fouling tools or accessories. It targets commercial and industrial HVAC-style systems, and the 3/4-inch NPT size gives a concrete connection point. The limitation is that compatibility is worded broadly as "some air-related devices" rather than as a model-specific list; matching the connection to your air system is up to you. The $73.99 price sits between the process cartridge and the 20-pack sediment set.
String Wound Sediment Water Filter
This 20-pack gives you a long run of replacement cartridges in the 10-by-4.5-inch Big Blue format. The string-wound design targets sediment such as rust, silt, and sand, and the 1/5/10 micron choices let you choose the filtration level for your feedwater. NSF certification against NSF/ANSI Standard 42 for material requirements is a concrete material-level assurance. The limitation is that this is sediment filtration, not carbon or chemical reduction, so it should be paired with other stages if those contaminants are present. At $152.45, it is the highest listed price in the comparison.
Final recommendation by use case
- For a high-pressure process application, the CUNO DDS Filter 13136-01 is the match because the pressure rating and NPT connection line up with DDS equipment.
- For a compressed-air line, the High Flow Industrial Air Filter is the pick when you want particulate removal plus automatic moisture drainage.
- If you need multiple water filter replacements and open-box condition is acceptable, the Process Filtration P/N 3P879 T15R10A set is the practical choice.
- For a large-format sediment housing, the String Wound Sediment Water Filter is the fit for long replacement intervals.
