Let’s get started!
RKIN U1 Countertop Reverse Osmosis System Overview
The RKIN U1 is a sleek and compact countertop reverse osmosis system that delivers high-quality, purified drinking water on demand. Unlike traditional under-sink RO systems, the RKIN U1 is designed to sit on your countertop, making it a great choice for renters, small apartments, or anyone who doesn’t want to drill holes in their cabinets or countertop.
The system is equipped with a powerful 5-stage filtration process that removes up to 99% of contaminants from your water, including heavy metals, chlorine, fluoride, pesticides, and more.
One great feature of the RKIN U1 is that it provides three different temperature options for dispensing water: hot, ambient, and cold. This means that you can have instant access to purified hot water for making tea or coffee, cold water for refreshing drinks, or ambient temperature water for cooking and other needs.
The RKIN U1 is easy to install and maintain, and requires no electricity or plumbing. Simply connect the system to your existing faucet with the included adapter, and you’re ready to go
The system is also designed with a convenient LED display that shows the remaining filter life and water quality, making it easy to monitor and maintain the system.
RKIN U1 Countertop Reverse Osmosis Filtration Capabilities
The RKIN U1 Countertop Reverse Osmosis system contains 5 filtration stages to remove several contaminants from the water. The filtration stages are:
- Stage #1: is a high-capacity sediment filter that removes large particles like sand, silt, and rust
- Stage #2: is a granular activated carbon filter that removes chlorine, chemicals, and organic compounds that affect the taste and odor of your water
- Stage #3: the core of the system, is a powerful RO membrane that removes dissolved solids and impurities from your water
- bacteria, and many other contaminants
- Stage #4: is a remineralization filter that adds beneficial minerals like calcium and magnesium back into the purified water, improving its taste and providing health benefits
- Stage # 5: is the hydrogen infusion stage in the RKIN U1 system that generates water infused with antioxidants and enriched with hydrogen
The result is clean, great-tasting water that is free of impurities and contaminants. The RKIN U1 can remove up to 99% of contaminants, making it a great choice for anyone who wants high-quality water in their home or office.
The RKIN U1 offers a comprehensive filtration system with a unique hydrogen infusion stage and remineralization filter to improve the taste and health benefits of purified water. While we haven’t been able to confirm third-party test results or NSF certification, the IAPMO testing data suggests that this system is capable of removing a wide range of contaminants.
RKIN U1 Countertop Reverse Osmosis Design Features
The RKIN U1 Countertop Reverse Osmosis System has several design features that make it a great option for those looking for a compact and stylish water filtration system.
First, the system is compact and designed for countertop use, so it won’t take up too much space in your kitchen. The sleek and modern design of the system also makes it an attractive addition to any kitchen décor.
Another notable design feature of the RKIN U1 is its ability to dispense hot, ambient, and cold water. You can choose the temperature of the water you want to dispense, making it a versatile option for various beverage and cooking needs.
One of the most impressive features of the U1 is its intuitive touchscreen display. The display makes it easy to control the unit and monitor its performance, showing the current temperature of the water and alerting you when it’s time to replace the filters.
In addition to its user-friendly interface, the U1 is built to last. The unit is made of food-grade ABS plastic and stainless steel, ensuring that it will withstand regular use and remain in top condition for years to come. The filters are also made of high-quality materials, designed to last and provide top-notch filtration performance.
Another key feature of the U1 is its noise-reduction design. The unit is built to operate quietly, with a built-in noise reduction pump that reduces noise during operation. This makes the U1 an excellent choice for use in a variety of settings, from the home to the office or even a small restaurant or café.
RKIN U1 Countertop Reverse Osmosis Performance
The RKIN U1 Countertop Reverse Osmosis performance is great when compared with the average RO systems.
One important aspect of reverse osmosis performance is its efficiency in terms of water usage. The RKIN U1 is an efficient unit, with a 1:1 wastewater to pure water ratio.
This means that for every gallon of pure water produced, only one gallon of water is wasted. This is a significant improvement compared to the average ratio of 1:4 for conventional reverse osmosis systems, which waste four gallons of water for every gallon of pure water produced. The U1’s efficient water usage can help you save money on your water bill and reduce your environmental footprint.
RKIN U1 Countertop Reverse Osmosis Capacity
The RKIN U1 Countertop Reverse Osmosis System is designed to produce up to 75 gallons of purified water per day, which should be sufficient for most households. However, it’s worth noting that the actual amount of water produced will depend on your water pressure and temperature, as well as the quality of your tap water.
The U1 has a half-gallon water tank that can be filled in 7 minutes, which is more than enough for most daily uses. The tank is made of high-quality, BPA-free plastic and is easy to remove for cleaning or refilling. It’s also worth noting that the tank is not pressurized, which means that the water is dispensed using gravity rather than a pump.
If you require more purified water than the tank can hold, the U1 features a convenient “continuous flow” mode that allows you to dispense water directly from the system without using the tank. However, this mode does require a drain connection.
All things considered, the RKIN U1 offers a good balance of capacity and convenience, making it a great choice for most households.
RKIN U1 Countertop Reverse Osmosis Installation & Maintenance
Installing the RKIN U1 countertop reverse osmosis system is incredibly simple and convenient. Unlike traditional undersink RO systems that require complicated installation procedures such as connecting to the main water line and drilling countertops to install a new faucet, the U1 can be set up quickly and easily without any plumbing experience.
All you need to do is find a suitable location in your kitchen, plug it into an electrical outlet, and the unit is ready to use. The manufacturer recommends running two full filtration cycles the first time you set up the system, which should take about 30 minutes. After that, you’re good to go!
Not only is installation a breeze, but maintenance of the RKIN U1 is also straightforward. The LED indicator lets you know when it’s time to replace the filters, which typically needs to be done once a year. The filters are easy to change, and it won’t take more than a few seconds to complete the task, without requiring any tools.
The RO membrane should last for 2-3 years before needing replacement, which the LED indicator will also alert you. The RKIN U1 features a zero-installation design, making it an excellent choice for apartment living or anyone who doesn’t want to deal with the hassle of plumbing in a filtration system.
Maintenance is also simple thanks to the system’s self-cleaning features. The UV light zaps the stored water to prevent microbe formation, and the “rinse” setting flushes the filters and drains the system. Although occasional cleaning of the exterior is necessary, the system doesn’t require regular dismantling for cleaning.
The wastewater tank should also be emptied occasionally, depending on your water usage. Although the reject water isn’t suitable for drinking, it can be used for other purposes such as cleaning or watering plants.
Generally speaking, the RKIN U1 is a low-maintenance and convenient solution for countertop reverse osmosis filtration. For further installation instructions, refer to the installation manual available here: RKIN U1 Manual
