Filtration separation usually starts with a simple question: do you need a direct replacement for an existing filter setup, or do you need a large stock of consumable bags for varied liquids and fuels? The two options here take opposite approaches. Process Filtration offers a water-filter set with a specific part number, while Duda Energy offers a bulk lot of sewn industrial filter sock bags that can handle water, liquid, biodiesel, WVO, oil, dust, fuel, and diesel. The first is narrow and ready for a known water-filter application. The second is broad and built for high-volume change-outs. The right choice depends on whether your priority is matching a part or stocking up on flexible filtration separation media.
Quick verdict
If your system is already set up around a specific water filter part, the Process Filtration six-pack gives you six new open-box filters in one order, and it costs less upfront. If you need to filter multiple liquids and want enough bags to keep replacing them, the Duda Energy lot of 50 sewn industrial filter sock bags is the higher-capacity, more versatile buy. The real difference is focus versus volume: one is a specific replacement filter, the other is a bulk bag inventory.
Price and quantity comparison
| Product | Price | Quantity | Relative Price | Key Spec |
| Process Filtration Water Filter 6-Pack | USD 49.99 | 6 filters | | Part number 3P879 / T15R10A |
| Duda Energy Sewn Filter Sock Bags | USD 316.00 | 50 bags | | Size #4: 4" x 14"; 0.5 micron rating |
Where each product wins
- Process Filtration wins if you want a direct water-filter replacement with a multi-filter lot and a known part-numbered set.
- Duda Energy wins if you need a large quantity of sewn filter bags for multiple liquids, fuels, and dust, and you have a housing that accepts these bags.
Product notes
Process Filtration Water Filter Set
The Process Filtration water filter set is built around a specific part: P/N 3P879, T15R10A. If your equipment already uses that replacement filter, the set gives you a ready supply without mixing part numbers. The listed price is USD 49.99, the condition is New - Open box, and the filters are made in the United States. Choose this option when your priority is a direct water-filter replacement with a known part number and you want multiple units in a single purchase. The limitation is scope: this is a water filter, not a sewn bag for biodiesel, WVO, oil, or fuel. If your filtration separation work involves those liquids, this set won't cover it. The open-box condition is also worth considering if your inventory process expects sealed retail packaging.
Duda Energy Sewn Filter Sock Bags
Duda Energy's sewn industrial filter sock bags are offered as a bulk lot, and each bag is Size #4, measuring 4" in diameter by 14" in length. The 0.5 micron rating points to fine filtration, and the intended uses include water, liquid, biodiesel, WVO, oil, dust, fuel, and diesel. At USD 316.00, the upfront price is higher, but you're stocking a much larger number of consumables for repeated change-outs. Choose this if you want a versatile bag supply for different filtration separation tasks and your housing is sized for these bags. The limitation is specificity: a bulk bag lot is only useful if the dimension fits your system, and the higher upfront cost is significant compared with the smaller filter set.
Final choice by use case
Match the option to your housing and your liquid: if you need a replacement water filter for a specific part-numbered setup and want several units on hand, the Process Filtration set is the more focused buy. If you need to cover multiple liquids and fuels and want sewn bags ready for ongoing filtration separation, the Duda Energy lot is the larger, more versatile purchase. Choose based on whether your priority is part-number compatibility or bulk bag capacity.
