JIMMY R9 Review: The Water Purifier That Will Make You Forget About Water Jugs

Gadget News » Gadgets » JIMMY R9 Review: The Water Purifier That Will Make You Forget About Water Jugs

Choosing how to drink water at home seems like a simple decision… until your tap water is no longer an option. In my case, the problem is quite clear: the water is very hard, has a lot of limescale, and isn't pleasant to drink directly . This has led me to rely on bottled water for years.

And this is where the real problem arises. It's not just the cost, but the inconvenience: having to remember to buy water, carrying heavy bags every few days, and not running out at home . It's one of those small, constant annoyances that, over time, become tiresome.

That's why I decided to look for a real alternative. And in that process, I came across a type of product that's becoming increasingly common: countertop reverse osmosis systems. Specifically, I've been testing the JIMMY R9 , a water purifier that promises to remove impurities without installation. The question was simple: can it truly replace bottled water in everyday use?

What is the JIMMY R9 and what does it offer?

The JIMMY R9 is a countertop reverse osmosis water purifier designed for direct use on the countertop without installation. Unlike traditional systems, it requires no connection to the water supply or modifications to the kitchen.

In general terms, we're talking about a system that combines multi-stage filtration, sterilization, and temperature control , allowing you to get hot or cold water instantly. On paper, the proposition is clear: to have filtered water at home without complications.

The first thing that catches your eye when you take it out of the box is its design. It's a compact, well-built device with a premium finish . It doesn't feel like something you have to hide away, but rather something you can easily integrate into your kitchen.

One of the key points is that it requires no installation . There's no need to drill holes, connect pipes, or modify anything in the kitchen. However, the first use does require an initial setup process.

The tanks need to be filled and emptied several times to clean the pipes and filters before you can start using it normally. In my experience, this process wasn't entirely intuitive using only the paper guide, but thanks to the included video tutorial (accessible via QR code ), it's much simpler. It's not complicated, but it does take some time , so keep that in mind before you begin.

How it works on a daily basis

It works quite simply. You put the water in the tank, and the system filters it and makes it ready for consumption. All you have to do is have a place to put it and refill the tank as it runs out, which is also easy since the machine itself alerts you when the water level is low.

Furthermore, it allows you to choose the water temperature, including instant hot water , which is a very useful extra feature if you enjoy drinking tea or coffee. However, caution is advised, as the water can reach very high temperatures (it practically reaches 100 degrees Celsius in just seconds), and it's important to use appropriate containers.

It's also important to mention something not shown in the video: the unit has a child safety lock . This is especially relevant if there are young children at home, as it prevents them from accidentally activating the hot water dispenser and getting burned.

Basically, it's a water dispenser that purifies water and can filter all types of water . In fact, as you saw in the video, I did several tests, and the results are, to say the least, surprising.

Real-world tests: this is how water is filtered

To verify if it truly delivers on its promises, I conducted several tests with different types of water . Each of these water samples has impurity levels measured by the TDS (Total Dissolved Solids) level . The higher the number, the worse the water quality. Therefore, the results were quite clear:

1. Unfiltered tap water: It started with an impurity value of 999 and, after filtration, It dropped to about 30 TDS.
2. Water with pre-filtered limescale: It started from about 500 and It was reduced to approximately 8 TDS after going through the system.
3. Bottled water: It started around 300 and the final result was only 4 TDS.

Beyond the exact numbers, the important thing is that in all cases the system clearly reduces impurities , demonstrating that the filtration works consistently. The system uses three main filters:

• Un first filter that removes large particles and visible impurities
• Un second reverse osmosis filterresponsible for reducing most pollutants
• Un third filter that reintroduces minerals to improve the taste of water

Regarding maintenance, filters 1 and 3 cost approximately €29,99 and last for about one year. The second filter lasts up to two years and costs around €39,99 . This is important to consider when calculating the actual long-term cost.

User experience: what changes on a daily basis

The first change you'll notice is the taste of the water. It's much softer, with less mineralization, and at first it might seem a little strange . However, it's just a matter of getting used to it, and in a few days it will become completely normal.

The real change comes in your routine. There comes a point when you realize you 're no longer buying bottled water . You simply refill the tank when needed and forget about the rest. With a capacity of about 3,5 liters , it's been more than enough for my daily needs without any problems. Furthermore, the system includes two separate tanks , allowing you to use one while the other is kept cold in the refrigerator—especially useful in summer or for having water ready at all times.

However, you need to pay attention: when the "!" indicator appears , the system indicates that it's necessary to empty the water tank and refill it with fresh water . This is due to the way the reverse osmosis system works; it needs to expel some of the water to clean the filter and maintain its performance. We use the wastewater for plants or cleaning, and that's it.

Speaking of daily use, I wanted to compare the cost of bottled water with the cost of the water purifier to see if it's worth it. The short answer is yes, it's worth it. I say this because, according to my calculations, the price of the JIMMY R9 is roughly equivalent to 250–300 bottles of water.

If a household with average consumption uses 2 liters of water per person per day, this translates to a payback period of between one and three years , depending on the size of the family. From then on, all the savings are immediate , in addition to the convenience of not having to constantly buy water.

However, although it incorporates an ultraviolet light system that helps keep the purified water in better condition for longer, the long-term cost of the filters must be taken into account , as this will be the main maintenance expense of the system.

Conclusion: Is it worth it?

After several weeks of use, the conclusion is clear: I think it's well worth it . In my case, it has completely replaced water jugs . And that, although it may seem like a minor detail, makes a big difference to my daily life. But first, let me tell you what, for me, is the best and worst thing about this JIMMY R9 water purifier.

The best:

• No installation needed and has a compact design, well finished.
• It practically replaces the use of jerrycans.
• The system It incorporates ultraviolet light to help keep the water purified. in better conditions
• Function of instant hot water.

Worst:

• Initial washing and start-up process somewhat slow.
• Act quickly. fill the tank manually.

However, it's not a product for everyone . If your tap water is already good or you don't mind relying on bottled water, you probably don't need it. But if you're in a situation like mine, where the water is hard and drinking from the tap isn't a realistic option, this type of solution makes much more sense than it might seem . Furthermore, the fact that it requires no installation and is so easy to use makes it a very attractive alternative not only for homes, but also for offices or small businesses.

That said, there's one point that remains to be seen over time: the actual lifespan of the filters, especially in hard water conditions like mine. But beyond that, the important thing is this: I've stopped relying on bottled water . And that makes a much bigger difference in my daily life than it seems.
