When you need to pick between two very different filtration separation options, the first fork in the road is format and volume. One side is a small set of Process Filtration water filters; the other is a large supply of Duda Energy industrial sock filter bags. The absolute price spread between them is USD 277.84, so this is a choice between a compact replacement set and a much larger bag supply. For a quick maintenance task, a few replacement filters may be all you need. For ongoing liquid filtering, a bulk bag supply can keep changeouts stocked.
Quick verdict
Choose the Process Filtration T15R10A set when you want a lower upfront spend and a compact replacement supply. Choose the Duda Energy sock bags when you need a large operational supply that is easy to remove from a filter bag housing.
At a glance
| Product | Price | Quantity | Format | Condition | Price position |
|---|---|---|---|---|---|
| Process Filtration T15R10A Water Filter | USD 49.99 | 6 | Water filters | New - Open box | |
| Duda Energy Welded Filter Sock Bags | USD 327.83 | 50 | Sock filter bags, Size 4 (4" x 14"), 0.5 micron, plastic ring flange | New |
The bars make it obvious that the price spread is wide and the bag lot is the larger investment.
Where each product wins
Process Filtration T15R10A wins for a lower total order price and a smaller replacement supply. When you only need a handful of water filters, the compact set keeps the commitment light.
Duda Energy Welded Sock Bags win for larger jobs and a more substantial supply. The bulk lot is better positioned for high-volume filtration separation.
The practical question is whether you need a short-term replacement or a stockpile for ongoing work. The compact set suits smaller tasks and smaller budgets; the sock bag lot suits operations where filter bag changeouts are routine.
Product notes
Process Filtration T15R10A Water Filter (Qty. 6)

This set gets you six Process Filtration water filters for USD 49.99, which makes it the easier entry point when you do not want to commit to a large lot. The part number T15R10A gives you a specific reference, and the set carries a United States country of origin. The condition is New - Open box, so you are buying an open-box six-piece set rather than a sealed bundle. If your filtration separation need is a straightforward water-filter replacement and you want to keep the upfront spend around $50, this set is worth considering.
Duda Energy Welded Filter Sock Bags (Size 4, Lot of 50)

The Duda Energy option is the bulk play: USD 327.83 for a lot of 50 Size 4 welded filter sock bags (4" x 14"). The welded construction avoids needle holes and thread contamination, and the fused edges help limit fiber migration in the working fluid. The plastic ring flange has handles for easy removal from a filter bag housing. The 0.5-micron rating gives you a specific filtration specification. The tradeoff is the upfront commitment: a 50-bag lot is much larger than the compact comparison set, so it makes sense when you have enough volume to work through it. If your filtration separation job involves water, liquid, oil, WVO, or fuel, these sock bags are the more substantial supply option.
Final choice by use case
For a low-volume water filtering task or a quick replacement, choose the compact Process Filtration set. For a high-volume filtration separation job with a large bag supply ready for ongoing work, choose the Duda Energy lot.
