Filtration Separation Guide: Pick Between a Filter Sock, 100-Bag Lot, and Powered Filter

Quick take

Choosing between these filtration separation products comes down to whether you need to refresh one filter sock, stock up for ongoing changes, or build a complete bag-filter setup. The four prices span a wide range, from a single replacement sock at the low end to a powered electric filter at the top. If you already have a housing, the single sock bag handles a quick swap. If you want a full station, the stainless housing and the electric filter are very different levels of machinery.

Decision matrix

• Filpro DE5D4SS: choose when you need one replacement sock and want the lowest cash outlay in this group.
• Duda Energy sewn filter socks: choose when your operation goes through many socks and you want bulk replacement quantity.
• TECHTONGDA 1# Bag filter: choose when you want a stainless bag housing with a strainer basket instead of loose socks.
• 220V Electric High Flow filter: choose when you want a powered filtration unit rather than a passive filter bag.

Product notes

Filpro DE5D4SS Industrial Liquid Filter Sock Bag

This is the lowest-priced unit in the comparison at USD 5.50. The Filpro DE5D4SS is a 5-micron industrial liquid filter sock bag, made in the USA, and the condition is New - Open box. The description points to food and pharmaceutical, microelectronics, chemical, and laboratory research use as part of a 3-stage filtration system. Choose it when you need one replacement sock without spending more. The limitation is the scale: it is a single unit, so a busy process will need many more than this.

Duda Energy Sewn Industrial Filter Sock Bags

This product is a 100-bag lot with a listed price of USD 400.70. Each sewn bag is Size#4, 4\" x 14\", rated at 5 microns, and made from singed polyester felt with heat-treated PE/PES fabric. The product title covers water, liquid, biodiesel, WVO, oil, dust, fuel, and diesel use. Choose it when you want a large supply of replacement socks rather than one-off changes. The limitation is the lot size and fixed Size#4 dimension: you are buying 100 bags at once, not sampling a single bag.

TECHTONGDA 1# Bag Industrial Filter 304 Stainless Steel

The TECHTONGDA unit is a stainless bag filter at USD 528.24. It is built around a 1# bag configuration, includes a stainless steel strainer basket, and is rated for 2\" NPT in/out at 120 PSI. The product description places it in fluid filtration and remediation service. Choose it when you want a housing sized for a 1# bag rather than socks by themselves. The limitation is the price: it is the second-most expensive product here, so you are paying for a hardware component instead of a box of consumables.

220V Electric High Flow Industrial Liquid Filter

This is the only product in the comparison with a motor and a self-priming pump. At USD 1,628.00, the 220V Electric High Flow filter is described as a vertical electroplating solution filter with a 6-core high-flow design, a 220V/750W motor, and a self-priming pump. The product title calls out electroplating nickel and chemical liquids, and the description says it removes solid impurities, particulates, and contaminants from plating solution. Choose it when you need a powered, higher-flow system rather than a manual bag change. The limitation is the price and scale: it is the most expensive product here and is built around continuous electroplating and chemical-liquid work.

Final recommendation by use case

• Need one replacement sock now: the Filpro DE5D4SS is the low-price path to a single filter sock.
• Need a large supply of filter socks: the Duda Energy sewn filter bags handle ongoing changes in bulk.
• Need a bag housing for 1# bags: the TECHTONGDA filter gives you the housing piece of the setup.
• Need a powered filter for chemical liquids: the 220V electric unit is the powered high-flow option in this set.
