Choose R9 for value; choose R9 Pro for cold-water convenience
Best value
Best when ambient and hot water cover your needs. You get the core countertop RO experience without paying for a cooling system you may rarely use.
Best all-in-one drink station
Best when chilled water is used every day and can replace a separate cooler, fridge pitcher or bottled-water habit.
The upgrade is cooling, not a new purification category
| Factor | R9 | R9 Pro |

Do not pay more expecting radically better filtration
The reason to upgrade is convenience, not a fundamentally different contaminant-reduction strategy. Both products are countertop RO appliances, so buyers should compare current model-specific treatment documentation, filter schedules and replacement availability rather than assuming the Pro removes more contaminants simply because it costs more.
If contaminant evidence matters more than temperature features, compare AquaTru Classic as an evidence-focused benchmark.
The Pro makes sense only if built-in cold water changes your routine
JIMMY's current R9 Pro specifications document 10–15°C chilled water, 100W cooling power and 1W standby power. That makes the Pro materially more convenient in warm climates, offices and households that would otherwise keep a separate cold-water appliance or pitcher in the refrigerator.
The standard R9 still covers ambient water plus six hot presets from 45°C to 98°C. JIMMY also markets its removable pitchers as refrigerator-friendly, so the cheaper model can still provide cold water—you simply chill the pitcher separately instead of dispensing it cold on demand.
Compare the cooling benefit against three years of ownership
The Pro adds a refrigeration load and extra hardware; the standard R9 does not. JIMMY lists a 100W cooling system and 1W standby power for the R9 Pro, so electricity use will depend on room temperature, cold-water demand and how often the cooling system cycles—not the 2200W rated heating figure alone.
Filter availability matters just as much. JIMMY currently lists 12-month composite and mineralized-carbon filters plus a 24-month RO membrane for the R9 Pro. Verify current regional cartridge pricing for the exact model before assuming both versions have identical long-term consumable cost.
For the broader framework, see countertop RO ownership cost.
Simple decision rule
Buy R9 if you want the better value, use hot water frequently and do not need chilled dispensing. Buy R9 Pro if cold purified water is used often enough to replace another appliance or bottled-water habit.
If counter space or refill frequency is the bigger issue, neither may be ideal. Compare countertop RO vs under-sink RO.

R9 vs R9 Pro: pay for the Pro only when its extra functions change daily use
Both machines compete as countertop purification appliances, so the first comparison is treatment evidence, reservoir workflow and dispensing performance. If both models document the contaminant reductions you need, the Pro upgrade should be justified by convenience rather than by assuming “Pro” means cleaner water. Compare hot-water presets, dispensing speed, tank capacity, footprint, noise and any specialty features you will actually use every day.
Ownership cost can erase a small purchase-price difference quickly. Verify whether the two models use the same replacement cartridges, whether filter bundles are interchangeable and what the realistic annual consumable cost is. Also check how easy the tanks and internal water path are to clean. For a user who mainly wants room-temperature purified water, the standard R9 may offer better value. The R9 Pro makes more sense when its additional temperature, dispensing or appliance features replace another device on the counter. Choose from workflow and total cost, not model naming.
R9 vs R9 Pro questions
What is the main difference between JIMMY R9 and R9 Pro?
The R9 Pro adds built-in 10–15°C chilled dispensing with a 100W cooling system. The standard R9 provides ambient and hot water; its removable pitchers can be chilled separately in a refrigerator.
Which is the better value?
R9 is usually the better value if ambient and hot water cover your needs. R9 Pro earns its premium when you will use built-in chilled water often enough to replace refrigerator-pitcher or bottled-water routines.
Do both use reverse osmosis?
Yes. Both are countertop reverse-osmosis systems with appliance-style reservoir operation.
Which is better for a small apartment?
R9 is usually the cleaner choice unless chilled water is important enough to justify the higher price and extra appliance complexity.
