Choosing a water filtration system usually comes down to a simple question: Are you filtering at home or carrying water with you? That decision separates a countertop unit from portable filters that fit into a pack. The four listings here split along that line: one countertop system and three Sawyer filters designed for on-the-go use. The trade-offs are mostly about capacity, carrying style, and the condition of each listing.
Quick Take
For a permanent home fixture, the RORRA countertop water filtration system is the only countertop listing in the group. If you plan to filter water while traveling, the Sawyer SP160 system gives you a larger reservoir than the mini filters. For solo packing, the Sawyer Products Mini Water Filtration System is the more complete mini option, while the other Sawyer mini in blue is available as a separate spare.

Product Notes
RORRA Countertop Water Filtration System Stainless Steel 2.5 gallon
Start here if you want a dedicated countertop unit rather than a bottle attachment. The stainless steel material and 2.5 gallon capacity make it the most substantial option in this group, and the silver finish fits a permanent kitchen spot. It is marked used and notes a minor dent, so you are accepting some cosmetic wear. The trade-off is that it is not a grab-and-go filter; it belongs on a counter, not in a backpack. That distinction alone separates it from every other listing here.
Sawyer Products SP160 One Gallon Gravity Water Filtration System w/Dual-Threaded
If your trips involve more than one person, this one-gallon gravity system gives you a larger reservoir than the mini filters. It is listed as new, and the dual-threaded design adds a practical connection point for gravity filtering. The main limitation is that this is a larger system than the mini filters, so it takes up more pack space. It sits between the countertop system and the mini filters, offering a portable option with more capacity than a straw-style filter.
Sawyer Products Mini Water Filtration System
This new mini filter is the more complete mini option because it includes a cleaning plunger. Its 0.1 micron absolute inline filter can attach to drinking pouches, standard 28 mm bottles, or hydration packs, so you can switch between carry styles. The capacity rating is 100,000 gallons, a strong endurance figure for a filter this small. The limitation is that it depends on a water source you can reach; you are not carrying a reservoir with you, just the filter mechanism itself.
sawyer products mini water filtration system
The other Sawyer mini is blue and listed as new but not in original packaging, with the missing bag called out and no water ever run through it. That combination makes it a simpler spare-filter option if you already have pouches or bottles to pair with it. The limitation is the condition label: new other means you are not getting an unopened retail package, and the missing bag is a missing component. The pump type also differs from the inline design on the other mini listing, so it may not attach the same way.
Final Recommendation by Use Case
For a home countertop setup, the RORRA countertop water filtration system is the only listing that fits that role, so choose it if you want a fixed unit; account for the used condition and the minor dent. For mobile use, the Sawyer SP160 Gravity Water Filtration System suits situations where you need a larger portable reservoir. For a single hiker or traveler, the Sawyer Products Mini Water Filtration System gives you a new filter with a cleaning plunger, while the sawyer products mini water filtration system works as a spare if you are comfortable with the missing bag and new-other state.
