Waterdrop Reverse Osmosis System Review (Installation Guide)

The moment you see what the Waterdrop RO System looks like, you realize that you’ve just met the next generation in water filtration. The design itself is revolutionary, and the unit looks nothing like the traditional RO systems with all the connections and cartridges. But there is more than meets the eye when we talk about this product particularly.

The fact that there is no storage tank is a considerable advantage. People have been struggling with storage space since forever, but this ends now. You don’t need to take up the whole cabinet underneath your sink. The absence of a storage tank also prevents the growth of bacteria.


Waterdop Reverse Osmosis SystemOnce you get the system, it will come with 3 filters included:

  • CF filter – that’s the pre-sediment and carbon-block filter.
  • RO filter – the actual reverse osmosis filter
  • CB – post-activated carbon filter

This trio will make sure to remove all the larger contaminants in the water thanks to the 3 filter layer. Next, the reverse osmosis comes into play, and that’s where it becomes impressive. The RO membrane is nothing like the other regular membranes out there. Thanks to the filtration accuracy of 0.0001μm, you will successfully get rid of about 99% of all contaminants in your water. Finally, the carbon block filter will make your water taste better, rendering it perfect not only for drinking but for cooking as well.

Another thing that impressed us is the presence of the LED display at the faucet. Thanks to it, you can monitor the quality of your water. If you see the system panel though, you will notice there is one more display that shows you the exact amount of TDS.

Efficiency and versatility are also essential elements when we talk about this RO system. First of all, water waste is significantly less. In fact, it is about 3 times less than all other good quality RO systems out there. The ratio here is 1:1. This means that each gallon of wastewater equals one gallon of filtered water.

When it comes to versatility, the system is so compact that you can have it hooked to your refrigerator and not necessarily to your kitchen sink.

Installation and Maintenance

This is where the WaterDrop RO system shines. Installation is effortless, and changing the filters takes only about 3 seconds. The biggest challenge you will face is the actual water line connection. It might take you about a half-hour to get it done. The machine itself doesn’t require any special attention when installing.

Don’t forget that you also have to drill a hole for the faucet. The recommended size id 1.38 inches. Additionally, once you are done connecting everything, your inlet water PSI should be between 14.5 and 87. Anything lower than 14.5 will not be strong enough for the unit to pump up any water.

Noise is often a problem when we talk about RO systems. Here, you will feel and hear only a slight vibration. The noise levels are going to be relatively low and shouldn’t be bothersome at all.

If you have a hot & cold spout at home, you can use that instead of the smart faucet which is included in the set. You only need to make sure the measurements are right. Otherwise, you will require fittings.

Filters are to be replaced every 6 months. If you ask us, this is an excellent lifespan as most systems will give you 2-3 months tops. Extensive use also needs to be taken into perspective, and this is why the manufacturer states that there is a 2nd metric sued to determine the life of the filters. In our case, it is 550 gallons of water.
