Filter Socks, Elements, or a Full Housing? Pick the Right Filtration Separation Setup

Compare four industrial filtration separation options from a 100-pack of sewn filter socks to a complete stainless steel housing with gauge, using listed prices from $5.50 to $534.36.

Last updated Aug 17, 2026

Choosing between industrial filtration separation formats starts with one question: do you need a consumable filter sock, a replacement filter element, or a complete filter housing? The four products here cover all three categories, with listed prices running from $5.50 to $534.36. You'll see a 100-bag lot of sewn filter socks, a single made-in-USA filter sock, a complete stainless steel filter with pressure gauge, and a drop-in filter element. The right pick depends mostly on how much media you need and whether you already have a housing to put it in.

Quick Take

  • High-volume media: Duda Energy Sewn Industrial Filter Sock Bags, 100 bags for USD 400.70.
  • Single sock replacement: Filpro DE5D4SS industrial liquid filter sock bag, USD 5.50.
  • Complete filtration setup: Industrial Filter with Pressure Gauge, 2" NPT inlet/outlet, USD 534.36.
  • Replacement element: Fluitek FSN-0108-02 industrial filter element, USD 39.99.

The price ladder here is straightforward: the complete housing costs more than any single media item, while the 100-bag sock lot sits in between. The 100-bag lot works out to about USD 4.01 per bag, which is under the single sock's listed price of USD 5.50. If you only need one sock, the Filpro item is the lower upfront cost.

Product Notes

#### Duda Energy Sewn Industrial Filter Sock Bags (100)

Sewn Industrial Filter Sock Bags Water Liquid Biodiesel WVO Oil Dust Fuel Diesel

This 100-bag lot uses sewn construction and is listed at USD 400.70. Each bag is a Size#4, measuring 4" x 14" in diameter and length, and the filter material is singed polyester felt that's heat-treated. The micron rating is 5 microns. The product title points to use with water, liquid, biodiesel, WVO, oil, dust, fuel, and diesel, so it's a broad-purpose media option. The main limitation is the lot size: at 100 bags, you're committing to a large quantity. If your operation changes media frequently, this quantity makes sense; if you need just one or two bags, the single Filpro sock is the smaller, less expensive way to start.

#### Filpro DE5D4SS Industrial Liquid Filter Sock Bag

INDUSTRIAL LIQUID FILTER SOCK BAG - Filpro DE5D4SS. 5 mcr. Made in USA. New

The Filpro DE5D4SS is a single industrial liquid filter sock bag listed at USD 5.50. Its model number is DE5D4SS, and the title confirms a 5-micron rating and USA-made origin. This is the lowest listed price in the group. Intended applications include food, pharmaceutical, microelectronics, chemical, and laboratory filtration. Because the listing is for one unit, the limitation is scale: a single sock is a good replacement or trial piece, but if you need a steady supply, you'd be placing multiple orders. It's a direct counterpoint to the 100-bag lot from Duda Energy.

#### Industrial Filter with Pressure Gauge

Industrial Filter with Pressure Gauge, 2"NPT Inlet Outlet Water Filtration Equip

This is the complete-system option in the group, listed at USD 534.36. It's a floorstanding filter with a pressure gauge and 2" NPT inlet/outlet threads. The body is made of 304 stainless steel with mirror polishing and a 2mm wall thickness. It takes a 180 x 810mm filter bag and has a reference flow rate of 30-40t/h with a maximum pressure of 1.0MPa. As a housing, its role is to hold a filter bag rather than be the disposable media itself. The limitation is the floorstanding design: it needs floor space and proper plumbing connections, so it's a bigger installation commitment than buying a filter sock or element alone.

#### Fluitek FSN-0108-02 Industrial Filter Element

NEW Fluitek FSN-0108-02 Industrial Filter Element

The Fluitek FSN-0108-02 is a replacement filter element listed at USD 39.99. The model number FSN-0108-02 is confirmed in both the title and item specifics. This is a new item, though the original packaging may show wear from storage. If you have a system that accepts this Fluitek element, this is a direct drop-in replacement. The limitation is specificity: this is an element for a particular model line, not a universal sock or bag. It's the middle-priced item in this selection, sitting above the $5.50 sock and below the $534.36 housing.

Final Recommendation by Use Case

  • Need a large media inventory: Duda Energy's 100 sewn filter sock bags at USD 400.70 spread the cost across many replacements.
  • Need one replacement sock now: Filpro DE5D4SS at USD 5.50 is the single-sock pick.
  • Need a whole filter station with a gauge: The industrial filter with pressure gauge at USD 534.36 gives you the housing and monitoring point.
  • Need a specific element: Fluitek FSN-0108-02 at USD 39.99 matches that model number.

Remember to match the filter format to your equipment before choosing.
