When you run a workshop or a whole-house water system, the dirt you need to remove isn't always in the same place. In a compressed air line, moisture and particles can shorten the life of tools and fittings. In an incoming water line, sediment can clog appliances and affect taste. The high-flow air filter with auto drain and the string-wound water filter pack both belong to the filtration separation category, but they solve opposite problems. Picking one starts with naming the line you want to clean.
Quick Verdict
Choose the air filter with auto drain if you need to pull liquid and particulates out of compressed air in a commercial or industrial setting. Choose the sediment water filter pack if you have a 10" x 4.5" Big Blue-style housing and want a long-running supply of NSF-certified cartridges.

Where Each Product Wins
The air filter wins when your priority is protecting pneumatic equipment. Its metal bowl and auto drain handle the liquid that collects in air lines, and the filter captures debris that could damage o-rings and valves. It also costs less than the water filter, so it's an affordable first step for a shop.
The water filter pack wins when you need consistent, high-volume sediment removal for a home water system. The string-wound construction is a good fit for heavily sedimented water, and the long filter supply plus large capacity means fewer reorder interruptions.
Product Notes
High Flow 5 Micron Industrial Air Filter with Auto Drain & Metal Bowl
This filter is built for compressed air line systems, removing 5-micron particulates and trapping liquid with its metal bowl and auto drain. The 3/4" NPT connection is common in shop air lines, and the 140°F maximum temperature fits typical industrial use. If your air tools are getting waterlogged or clogged, this is a straightforward addition to the line. The trade-off is that it's not a water filter at all, so you can't use it to clean incoming water. It's also sold as a single unit, so you'll need to order replacements one at a time rather than stocking up.
20 Pack 10" x 4.5" String Wound Sediment Water Filter 1/5/10 Micron for Big Blue
This 20-pack from Membrane Solutions gives you a generous supply of sediment cartridges for 10" x 4.5" Big Blue-style housings. The food-grade polypropylene material is lead- and BPA-free, and the filters are certified against NSF/ANSI Standard 42 for material requirements. With 1, 5, and 10 micron options, you can choose how fine to filter. The 30,000-gallon capacity rating means long service life between changes. The main limitation is the upfront cost-$152.45 is the higher price of the two, and the 20-count is only practical if your housing setup actually uses that many filters.
Final Choice by Use Case
If you're filtering compressed air in a workshop, go with the High Flow 5 Micron Industrial Air Filter with Auto Drain & Metal Bowl for its metal bowl, auto drain, and 5-micron protection. If you're filtering whole-house water and want a long-lasting supply of sediment cartridges, pick the 20 Pack String Wound Sediment Water Filter for its NSF-certified material and interchangeable micron ratings. For a shop plus a home, the two serve different lines, so they can coexist rather than compete.
