Dreo Countertop 7-Stage RO Filtration Reverse Osmosis Water Filter System

A: It is 5.9 feet long (approximately 1.8 meters or 70.8 inches)

A: If the "Clean Tank" message remains on the display, it usually indicates a sensor misalignment, a temporarily stuck float valve, or air trapped in the system. Please try the following troubleshooting steps to clear the message: Perform a System Reset: Empty the raw water tank completely. Unplug the machine from the power outlet and wait for about 3 minutes. Plug it back in, refill the tank with fresh tap water, and place it back on the base. Check the Tank Placement and Cover: Ensure the water tank is seated properly on the base. Make sure the tank cover is completely flush and aligned with the main unit, as a loose or misaligned cover can trigger sensor errors. Verify the Float Valve: Look inside the water tank to locate the internal float valve. Gently tap or move it to ensure it can float freely and is not stuck or jammed by mineral buildup. Release Trapped Air (Spring Valve): Before placing the full tank back onto the machine, press the spring valve at the bottom of the tank with your finger for about 5 seconds to release any trapped air pressure. Purge the Internal Lines: If the error persists, remove the pure water pitcher, then press and hold the reset/configuration button on the panel to help purge any trapped air from the internal water lines. If the "Clean Tank" message still won't clear after trying these steps, please contact DREO Customer Support directly with your order details so we can assist you further or arrange a warranty check.

A: Yes, the unit needs to be plugged into a power outlet to operate. When it is not in use, you can simply unplug it from the socket.

A: The replacement filter costs $49.99.

A: Yes, the system is capable of reducing nitrates as part of its reverse osmosis filtration process.

A: The filter includes multiple filtration materials, and it does contain coconut shell-based activated carbon as one of the key layers. This coconut shell activated carbon is made from high-quality coconut shells and processed through high-temperature carbonization (around 600–900°C) followed by steam activation. Under this manufacturing process, any potential allergenic coconut proteins are almost completely removed, so it is generally considered to have negligible allergenic risk.

A: The water is dispensed automatically through the sensor-based system together with the included pitcher. It is not designed for manual dispensing via a separate button.

A: The machine does not have a dedicated remineralization function. However, it is designed to remove harmful contaminants such as heavy metals and impurities while retaining some beneficial minerals in the water. It can display the purified water TDS, but it does not measure or display pH values.

A: This unit does not include a UV sterilization function. It uses a 7-stage RO filtration system instead. The RO membrane (0.0001 micron) can effectively remove bacteria and microorganisms from water, with a removal rate of up to 99.99%. In addition, the system can remove over 1000 types of impurities and help inhibit bacterial growth, which is beyond what many standard filters can achieve.

A: It uses a 7-in-1 RO composite filter (PCRC). Key features include: Removes up to 99.99% of contaminants and effectively inhibits bacterial growth Achieves about 92% desalination rate for consistently high-purity water NSF/ANSI 58 certified, ensuring water safety standards are met
