As a water purification process, Reverse Osmosis (RO) relies on a partially permeable membrane to remove contaminants from water. Pressure plays an important role during the process – the applied pressure must be higher than the osmotic pressure. The osmotic pressure is a colligative property that is based on the thermodynamic parameter called chemical potential differences of the solvent. In the end, the solute stays on the pressurized end of the membrane, while the pure water passes through the membrane to the other side. The “selective” nature of the membrane means only filtered, contaminants-free water molecules pass through it; the large molecules or ions do not.

As a standard appliance, this product will need to be plugged into one electrical outlet to function normally.

The CF filter features a 6-month lifespan and the MRO filter can last up to 18 months, so you won’t need to replace them until much later.

The N1 countertop reverse osmosis water dispenser is installation free and requires no drilling nor messy holes.

A countertop water filter gives you access to clean water right at your kitchen sink.

You need no tools or plumbing skills to install the system. So, if you are in a rental home or temporary living space as well as small apartments where you cannot have under-sink installations, please consider this countertop water filter.

You will find several countertop water filter models in the market. But when choosing, look out for models with a RO membrane. That’s not all, you should also consider other important features like the water flow rate, certification, filter life time, and size.

Our system uses advanced drain water recycling technology. The recycled water will go back into the feed water tank, so the TDS value of the water in the tank will be higher than that of the feed water. With this technology, you will save more water than the traditional reverse osmosis system.

When the machine start to filter water, the recycled concentrated water continuously enters the feed water tank, resulting in a continuous change in the TDS value when the concentrated water mixes with the raw water. It tends to be stable after filtration.

a. This might be the case if the countertop reverse osmosis system is not fully flushed. Only use the machine after flushing according to the instructions for the first installation.

b. This might also be the case if the system has not been used for a while. Follow the emptying mode to flush.

c. This might happen if the filter has not been replaced after expiration. In this case, please replace the filter immediately.

Yes. Impurities don’t stand a chance with our countertop RO system. The two filter cartridges were made of reverse osmosis membrane, carbon block, and PP cotton.

When the TDS value of the filtered water is higher than 99ppm and the water quality is poor, the screen will display L1 to prompt a water change. The continued use of the water in the feed water tank will shorten the filter life and damage the machine. Therefore, when the machine displays L1, please pour the water out of the feed water tank and replace it with new water to use the machine.

a. This might be the case if the machine is not powered on. Check on whether the power plug is loose or not plugged in.

b. There might be insufficient or no water in the purified water tank (not the feed water tank). The screen displays a countdown of 99 seconds and water will be taken after the countdown is over.

This might be due to:

a. A full drip tray. Please empty the water stored in the drip tray.

b. A foreign matter getting stuck in the check valve at the bottom of the feed water tank. Please use a small thimble or your finger to resist the sealing valve and remove the foreign matter.

c. A leakage inside the machine. Kindly turn off the power and water supply and contact our customer service team.

We do not recommend using well water as source for our RO systems. The reasons are as follows:

1. Large particles.
Compared to municipal tap water, the well water is rich of large particles, which will clog the filters easily, and shorten their lifetime significantly.Please note that the filters will still need to be replaced more frequently, even if you have added a pre-filtration system.
2. Composition
The well water has very complicated compostion, and some of them (apart from the large particles) can cause the filter or internal valve to be clogged and prevent the RO system from normal performance.
3. Water pressure
The well water may not provide the feed water pressure that the RO system requires (14.5 psi min.). Furthermore, the water pressure will be even lower after passing through pre-filtration systems.
