Portable water filtration can be a difficult purchase when you want a compact RO system but are choosing among nearly identical K8680 names. The practical decision is whether the lower listed price, a stated water-TDS ceiling, specific unit dimensions, or package measurements best fit the way you plan to use and carry the system.
Quick take
All four entries are new, black K8680 countertop reverse-osmosis systems with portable water-filtration positioning. The Purewell® K8680 entry stands out for its stated maximum supported water TDS level of 300 PPM and the lowest listed price. The two K8680 RO Water Purifier System 10-Stage RV Portable Filtration UV Survival Gear entries use the same title but have different listed prices and package dimensions. The black K8680 RO Water Purifier System,10-Stage RV Portable Water Filtration entry is the highest-priced choice and includes specific unit dimensions plus a component list.
Listed price comparison
The listed prices span $115.51, from the Purewell® K8680 entry at the low end to the black K8680 portable water-filtration entry at the high end.

Product notes
Purewell® K8680 RO Water Purifier System,10-Stage RV Portable Water Filtration S
This is the clearest starting point for a shopper prioritizing the lowest listed price while still wanting a countertop K8680 RO system. Its included components name a PP pre-filter, RO filter element, 5200 mAh lithium battery, charger, compass, and storage bag, which aligns with the portable and RV-oriented wording in the title. The description also identifies a 0.0001-micron RO membrane. The key limitation is its stated maximum supported water TDS level of 300 PPM, making that number an important fit point for the water you intend to filter. Its listed unit dimensions are 9.45 x 4.9 x 12.4 inches.
K8680 RO Water Purifier System 10-Stage RV Portable Filtration UV Survival Gear - USD 313.44
Pick this entry when the 16.7 x 13.3 x 9.3-inch package dimensions work well for your packing plan and you prefer the UV survival-gear wording in the title. It is identified as a Purewell K8680 in black with countertop installation, reverse-osmosis purification, and ABS, metal, and copper materials. The description pairs the RO membrane with a dual-system UV lamp, supporting its travel, team-camping, and survival-focused positioning. Its limitation is the listed USD 313.44 price: it sits above the Purewell® K8680 entry, so the package size and UV-oriented description need to be meaningful priorities for your selection.
K8680 RO Water Purifier System,10-Stage RV Portable Water Filtration Black
This black K8680 entry is useful for shoppers who want a clearly stated unit footprint before selecting a countertop purifier. The item dimensions are listed as 9.45 x 4.9 x 12.4 inches, and the included components name a PP pre-filter, RO filter element, 5200 mAh lithium battery, and charger. Its description also identifies a 0.0001-micron RO membrane and dual-system UV lamp. The limitation is straightforward: USD 368.50 is the highest listed price in this group. Choose it when those stated dimensions and named components fit your needs rather than simply looking for the lowest entry price.
K8680 RO Water Purifier System 10-Stage RV Portable Filtration UV Survival Gear - USD 312.85
This entry makes sense when you want the same named K8680 UV survival-gear format at USD 312.85 and its 17.0 x 14.0 x 9.0-inch package dimensions fit the storage space you have. It is listed as a black Purewell countertop model with reverse-osmosis purification and ABS, metal, and copper materials. The description presents it for drinking water, team camping, and travel, while the title keeps the RV portable-filtration focus front and center. Its practical limitation is the larger listed package length and width than the other UV Survival Gear entry, a consideration if compact packing is your main goal.
Final recommendation by use case
For the lowest listed-price route and a stated 300 PPM supported-water-TDS ceiling, choose the Purewell® K8680 RO Water Purifier System,10-Stage RV Portable Water Filtration S. For a transport plan built around the smaller of the two listed UV Survival Gear package measurements, select the USD 313.44 K8680 RO Water Purifier System 10-Stage RV Portable Filtration UV Survival Gear. Choose the black K8680 RO Water Purifier System,10-Stage RV Portable Water Filtration when its exact unit dimensions and component list are your priority. The USD 312.85 UV Survival Gear entry is the fit for shoppers working with its 17.0 x 14.0 x 9.0-inch package size.
