How to Choose the Right Jimmy RO
-
Check installation type
Both models are countertop units, making them ideal for renters who cannot drill into cabinets. You do not need permanent plumbing connections. This design allows you to move the system if you relocate. Verify that your counter has enough space for the unit's footprint. The portable nature means you can store it away when not in use. This flexibility is the primary advantage over under-sink systems. You get clean water without modifying your kitchen structure.
-
Compare weight and size

It measures 13 by 9.9 inches. Choose the lighter model if you plan to move it often. The heavier Pro model offers more stability but takes up more space. Measure your available counter area before deciding. Weight affects how easily you can carry the unit.
-
Look for UV filtration
Both the R9 Pro and the standard R9 include UV filtration. This feature adds an extra layer of purification beyond standard RO membranes. UV light neutralizes bacteria and viruses effectively. You get higher water purity with this technology. Check that the UV lamp is included in the system. This spec ensures you are not buying a basic unit. It is a key differentiator for health-conscious buyers. Verify the UV component is present in your chosen model.
-
Decide on temperature control
The R9 Pro offers both hot and cold water dispensing. This is useful for making tea, coffee, or cold drinks instantly. The standard R9 model focuses on hot water only. If you need cold water, the Pro is the better choice. Consider your daily beverage habits. Instant hot water saves time on heating. Cold water adds versatility. Check the temperature settings in the specifications. Match this feature to your kitchen workflow and needs.
-
Review color and design
The R9 Pro comes in gray-black, while the standard R9 is gray. Your kitchen decor might influence this choice. The Pro has a darker, more modern look. The standard model is a lighter gray. Both have a clean, portable design. The color does not affect performance but matters for aesthetics. Check the visual style that fits your counter. The design is consistent with countertop convenience. Ensure the color matches your existing appliances or decor scheme.
