Waterdrop N1 Reverse Osmosis Review 

The journey to selecting the right water filtration system can be as murky as unfiltered water itself. That’s why we’ve taken a deep dive into the Waterdrop N1 Countertop Reverse Osmosis System. 

This section aims to clear the waters, providing an in-depth look at each aspect of the N1, from its sleek design to the quality of water it delivers. 

Join us as we filter through the details to help you decide if this system should be your next kitchen cornerstone.


The Waterdrop N1’s design is a blend of functionality and modern aesthetics. Its slim profile and clean lines mean it won’t just be another appliance on your countertop but a conversation piece. 

Waterdrop N1 Filtration process

The minimally designed removable 1-gallon tank is not only space-saving but also ensures that water is filtered on demand, providing a continuous supply of fresh water whenever you need it. 

The thoughtful placement of the intuitive LED display complements the overall sleekness, offering easy access to the system’s status without compromising on style.

At the heart of the Waterdrop N1 is its powerful filtration system. It employs a composite filter that combines multiple filtration technologies, including a pre-sediment layer, an activated carbon block, and a reverse osmosis membrane.

This multi-stage approach ensures that water endures a thorough purification process, tackling various contaminants, from large particles to microscopic impurities. 

The ease of replacing these filters is a testament to the user-friendly design of the N1, requiring no tools and minimal effort to keep the system running smoothly.

Contaminants Removed

The Waterdrop N1 shines in this regard, with its reverse osmosis membrane filtering out up to 99% of harmful substances. 

This includes common culprits like lead, chlorine, fluoride, and a range of pathogens, ensuring that your water is not just clean, but safe for consumption. 

It’s a relief to know that the water you drink is stripped of unwanted guests, leaving nothing but purity in your glass.

Filter Lifespan/Maintenance

One of the most significant advantages of the Waterdrop N1 is the longevity of its filters. 

Replace the CF filter every 6 months and the MRO filter every 18 months to maintain optimal performance and purity. Designed to last, these filters reduce the frequency of replacements, saving time and money in the long run. 

The system’s automatic cleaning feature is a standout, minimizing the need for manual maintenance and ensuring the longevity of the filters. This self-cleaning function is a clear indicator of the N1’s commitment to providing a low-maintenance solution to water purification.

Water Quality

The proof is in the pouring, and with the Waterdrop N1, the water quality speaks for itself. Post-filtration, the water is noticeably fresher and crisper to taste. 

The removal of contaminants not only makes the water safer but also improves its taste and odor, making for a more enjoyable drinking experience. 

Whether you’re using the water for drinking, cooking, or brewing coffee, the difference in quality is palpable.

Warranty and Customer Service

Waterdrop stands behind the N1 with a solid warranty, ensuring that any issues you might encounter will be addressed promptly and effectively. The brand offers a 30-day risk-free return policy that applies to all items, including this product.

Their customer service has a reputation for being accessible and supportive, providing peace of mind that goes beyond the product itself. Knowing that help is just a call or email away adds an extra layer of confidence in the investment.


The installation process of the Waterdrop N1 is refreshingly straightforward. The system is designed for a hassle-free setup that can be completed without professional help. 

Clear instructions and quick-connect fittings mean you can have the system up and running in no time, making it an ideal choice for the DIY-inclined. 

The simplicity of installation is a nod to the user-friendly ethos that Waterdrop has woven into the fabric of the N1.

What’s Included

Upon unboxing the Waterdrop N1, you’ll find everything needed to get started. The package includes the filtration unit, equipped with all necessary filters, so all you need to do is plug it into a power source. 

Also included are a user manual and quick start guide, which lay out the maintenance processes in an easy-to-understand manner.

Waterdrop N1 Vs. Waterdrop A1

For those looking for a more basic filtration system, the Waterdrop N1 might be suitable, whereas the A1 is for those who prefer a few more bells and whistles. 

Aside from the price tag more than doubling that of the N1, the primary stand-out feature of the A1 is its ability to produce both cold and hot water at the push of a button.

Let’s take a closer look at how the two products compare:

Waterdrop N1
  • Price: $219-$299
  • Dimensions: 17.1” x 7.0” x 15.5”
  • Flow Rate: 100 GPD
  • Drain Ratio: 3:1
  • Capacity: 1-gallon
  • Filter Lifespan: CF-6 months, MRO-18 months
  • Warranty: 30-day risk-free return
  • Water Temp: Ambient
Waterdrop A1
  • Price: $699.00
  • Dimensions: 18.3” x 7.8” x 17.1”

  • Capacity: 1.6-gallons
  • Filter Lifespan: CF-6 months, MRO-12 months
  • Warranty: 30-day risk-free return

The Waterdrop N1 and A1 models cater to different needs and preferences. The N1 is a more budget-friendly option with essential features for pure water, while the A1 steps up with additional functionalities like hot and cold water dispensing, a larger capacity, and advanced filtration technology. 

Your choice between the two will depend on your specific requirements, whether you prioritize cost savings with the N1 or the enhanced features and convenience of the A1.

What We Like About the Waterdrop N1 (Pros)

  • Compact Design: The Waterdrop N1 boasts a sleek and compact design, measuring 17.1” L x 7.0” W x 17.8” H, which allows it to fit comfortably on most countertops without taking up too much space.
  • Tank Capacity: It features a removable 1-gallon water tank that automatically purifies and stores water, making it convenient for immediate use without the need for continuous water supply.
  • Advanced Filtration System: The N1 is equipped with a 2-stage filtration system, including a 0.0001-micron RO membrane and a UV light that activates hourly to eliminate bacteria and viruses, ensuring exceptionally pure water.
  • Efficient Drain Ratio: The system operates with a 3:1 pure-to-drain ratio, which is quite efficient compared to many other RO systems, meaning less water is wasted during the filtration process.
  • High Flow Rate: With a flow rate of 75 gallons per day, the N1 can easily meet the daily water needs of most households, providing quick and convenient access to purified water.

What We dislike about The Waterdrop N1 (cons)

  • Limited Filtration Stages: While the N1 has an advanced 2-stage system, some users might prefer more stages of filtration for even broader contaminant removal.
  • No Re-Mineralization: Unlike some other RO systems, the N1 does not have a re-mineralization stage, which some users prefer for adding beneficial minerals back into the water after filtration.
  • No Hot/Cold Water Options: The N1 provides ambient temperature water only, lacking the feature of dispensing hot or cold water that some advanced models offer.

Final Thoughts

We appreciate the Waterdrop N1 Countertop Reverse Osmosis System for its blend of simplicity and effectiveness. It aligns with our ethos of providing safe, clean drinking water without complex installation or maintenance. 

The system’s compact design and advanced filtration, including UV sterilization, meet our standards for high-quality water purification. 

While we do note the absence of features like re-mineralization, the N1’s user-friendly interface and self-cleaning capabilities make it a standout option for households prioritizing ease and reliability. 

The added assurance of a 30-day risk-free trial reflects a commitment to customer satisfaction that we value in our industry.
