What is reverse osmosis water systems?

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.

Do you need to have an electrical outlet for this work?

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

How often do you need to replace Waterdrop countertop water dispenser with filter?

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.

How to install countertop water dispenser with filter?

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

What is the best countertop water dispenser?

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.

Why is the TDS value in the feed water tank higher than that of the added tap water?

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.

Why is the TDS value in the feed water tank always changing when the machine filters water?

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.

Why does the water have a peculiar smell?

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.

Are top reverse osmosis systems worth it?

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. The entire process wipes out most of the harmful substances in your tap water, recording up to 90% TDS reduction rate and significant improvement in water taste.

If the water in the feed water tank does not get to the lowest water level, the machine displays L1 to prompt a water change. What does this mean?

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.

Why is the machine not delivering filtered water?

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.

Why is the countertop water dispenser leaking?

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.

Is this reverse osmosis water filter system unit suitable for well water?

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.
UV Sterilization
The UV light is automatically activated every hour to eliminate bacteria and viruses in the feed water, leaving you with pure and safe filtered water ready for drinking.
Next Level Filtration
Our countertop reverse osmosis system leaves impurities with no chance. The two filter cartridges are powered by a combination of reverse osmosis membrane, carbon block, and PP cotton. The entire process wipes out most of the harmful substances found in your tap water, recording up to 90% TDS reduction rate and significant improvement in water taste.

Great Item, My first RO system

Wanted an RO countertop system and kept looking on Amazon through a few and this one was my choice, Great product works well. had a few questions and customer support was on top of it . I have been using this system for almost a month I didn't see any dripping like other review mentioned, the only thing am not happy with, the slower rate of filtration and that 99 second counter but you learn to manage

filters 92% Countertop unit........ but it drips too much

I like this. This will filter out about 90% of contaminants in your water. The cleaner the water that you put in, the cleaner it will come out. My tap water measures at 180 TDS and this machine brings it down to around 15. I am assuming that over time and with use, the tds output will increase as the filter gets used, but the RO filter has an 18 month life until you need to change it. This could vary though based on the quality of water you are putting into the machine. This is easy to set up ANYWHERE. You just need to plug it in. It is narrow, but long and may not work so well under a cabinet because you need to access the back to fill and replace the 1 gallon water tank. If you put it under a cabinet, you will just need lots of room to slide it out whenever you need to refill the tank. This machine also has a built in UV light. I was surprised by that, I like it. You can use pre-measured amounts, 4oz, 8oz, 16oz or put it in manual mode and stop it when you want, up to 50oz. The TDS display is accurate as the water comes out. There is another small internal tank inside that stores some of the pure water so it is always ready to dispense. While the filtering is not as good as an under the sink RO system, this requires no plumbing, no drain line, and can be used anywhere there is an electrical outlet. It does drip a bit and there is a drip tray to catch it. I would leave a glass on there instead. I don't know how much it will drip overnight, but I will soon find out. This is a great option for an apartment, office, dorm.... As far as the dripping, it does drip and overnight (12 hours) I have about 6 oz in the glass I leave on the drain try to catch the drips. I tested that water with a tds meter and it is clean water too. I would not use this in an office over the weekend without leaving a large glass on the drip tray but also emptying the water container and probably unplugging it too. You really could end up with quite a mess over a few days time if there is nobody available to at least monitor this unit. UPDATE: After using this for a few days, the drips have not stopped. I am now monitoring this closely and getting 50 ml in 3 hours. This is 1.7oz. IF this keeps up at this rate, this equates to 14oz in 24 hours. I am not sure if it increased or not. When I first noticed the dripping, the time and amount were not carefully monitored. I do not know if I have a defective item or not or if there is a design flaw. I will continue to monitor the drippings. Waterdrop has offered to replace the unit and this will, I think, determine if it is defective or just a design flaw. I will update in about a week after receiving the replacement unit.


The Waterdrop RO system was very easy to install and the video showed how to install it. And be sure to purge the system a few times and throw out the first 2-3 tanks of wastewater for plants or another non-drinking purpose. The Waterdrop water taste is excellent I put a non-BPA container in the fridge and fill it for use. I had no room under the sink for that type of system and this one works fine and the cost is about or less the same as under the sink, due to installation. I am very satisfied with this system.
