CUW4 Tankless Water Filter System

Why Choose Aquacube (CUW4)? The CUW4 is a simpler and more compact alternative to traditional reverse osmosis systems. It is highly recommended for filtering and purifying municipal water supplies. The advanced 4-stage design of the CUW4 incorporates sediment, activated carbon, and ultra-filtration filters to effectively eliminate a wide range of contaminants, such as bacteria, algae, fungi, giardia, lead, arsenic, iron, nickel, chromium, cadmium, calcium, aluminum, mercury, chlorine, chlorine treatment by-products, pesticides, hydrogen sulfide, and other organic compounds. By using the CUW4, you can enjoy safer, healthier, and better-tasting water without the hassle, expense, and negative environmental impact associated with bottled water.

Flexibility, quiet operation, and durability are important features of the CUW4. The integrated design does not have any moving parts, making it easy to maintain. Our high-capacity, high-performance filters have a longer lifespan and provide maximum water flow, resulting in a noticeable difference when you turn on the faucet. With the click on/off filter design, changing filters has never been easier. The tankless system eliminates wasted space.

This system includes a lead-free faucet with a beautiful chrome finish, typically mounted on the counter as the primary source of drinking water. Additionally, the CUW4 can easily adapt to fit almost any refrigerator or ice maker connection.

The CUW4 has been designed to be easily installed by most users, using tools readily available. The pre-assembled system includes push-to-connect fittings that simplify the installation process and reduce the likelihood of leaks. An organized instruction manual provides step-by-step guidance for installation and testing. In the event of any issues or difficulties, our technical support team is available to assist you from 9 am to 5 pm Eastern time, Monday through Friday in Georgia.

If you require a reduction in overall dissolved solids (TDS) in your water or need to remove heavy concentrations of harmful metals like lead or copper, we recommend a reverse osmosis system like the PureDrop RTW5. However, if you are looking for all-around high-performance water filtration or have limited space, the CUW4 is the best, most economical, and flexible choice to instantly provide clean, fresh, and great-tasting water.

[Enhanced Water Taste]: The 4-stage under-sink water filtration system, equipped with a 0.01-micron Ultra Filtration (UF) stage, effectively removes up to 99% of problematic pollutants, including chlorine, chlorine treatment by-products, lead, arsenic, and more, while retaining essential minerals.

[Efficiency and Convenience]: Experience a faster water flow (0.32-0.5 GPM as opposed to 0.03 GPM with traditional water filter systems). This unit can be placed underneath the sink or connected to your refrigerator (ICEK needed). The sleek, modern, and compact design eliminates the need for a tank, conserves water, and operates quietly. Stay informed about the filter's status with the integrated LED filter change indicator. Starting it is as simple as pressing and holding both buttons.

[Simple Installation and Maintenance]: Minimize the hassle with an installation time of less than 30 minutes. The unique design of the integrated water route significantly reduces installation time, and the click-on filter installation ensures easy maintenance.

[Durable and Reliable]: All filters, tubing, and other water-contacting components strictly comply with industry and NSF/ANSI standards. Feel free to contact us with any questions or concerns. We prioritize customer satisfaction and will respond promptly.

[Note]: To access the filter replacement indicator, simultaneously press both RESET BUTTONS. This 0.01-micron Ultra Filtration (UF) unit does not reduce the TDS of incoming water but retains essential minerals. If you are interested in a filter that removes TDS, please consider a reverse osmosis system like the PureDrop RTW5.
