Waterdrop Filter Review (2021) – Worth the Money? 

The Waterdrop Direct Connect is a high-quality, yet affordable under-the-sink filtration system that ensures clean, healthy drinking water and a dramatically reduced need for plastic water bottles.

The Waterdrop system uses multistage filtration to get rid of such pollutants as Chlorine, rust, sediment, and harmful heavy metals with a filtration accuracy of 0.5 micrometers. Because the Waterdrop is one of the most popular under-the-sink filtration systems on the market, we’ve gone in-depth to review the Waterdrop’s features, pros, and cons!

Overview of the Waterdrop 

The Waterdrop Direct Connect Undersink Water Filtration System is designed to be used throughout the home (kitchen and bathroom), in the office, or in an RV. It is simple to install, does not take up much more space than would a typical water bottle, and employs a long-lasting filter. These features, plus others, make the Waterdrop a great option for anyone who has never before purchased a water filtration system, and/or who is in the market for a low-maintenance system.

Certification by the Water Quality Association (WQA) and recognition by NSF International should provide additional peace of mind to potential customers. The Waterdrop’s standout feature is its unique five-stage filtration process. The system employs an activated carbon block membrane to remove contaminants like Chlorine, chloramines, Lead, Fluoride, and Mercury.

While most other multistage filtration systems require the use of two or more filters, the Waterdrop requires just a single filter for its process. This makes the Waterdrop under-sink water filter more efficient, easier to maintain, and over time, less expensive than many of its competitors. Over time, the Waterdrop proves to be a cost-effective choice of water filter. During the Waterdrop system’s first year of use, you will spend approximately nine cents per day on water.

Beyond the first year, as the water quality continues to improve, you will spend only about four cents per day. This means that the Waterdrop filtration system is a system that is meant to be long-lasting and effective for a number of years. The Waterdrop seems to work just as advertised. Its much-lower-than-average price point makes it an appealing choice on its own, yet this product also boasts innovative and thoughtful design aimed at convenience. 

Waterdrop Features

The following are the standout features of the Waterdrop:

1. Single filter: Nearly every other under-the-sink water filter uses multiple filters to complete its filtration process. The Waterdrop utilizes just one five-stage filter inside its filter cartridge. This single filter removes a variety of harmful chemicals and heavy metals such as Chlorine and lead. Even better, the filter is easily replaced in seconds, as it requires a simple twist and lock. 

2. Push-Connect fittings: Installing the Waterdrop onto your sink’s waterline is as simple as it could possibly be thanks to the system’s innovative push-connect fittings. 

3. Simple design: The single filter and the push-connect fittings are just two examples of Waterdrop’s overall simple design. Everything about the Waterdrop is thoughtfully designed, and it is obvious that efficiency and easy use were top priorities during the design process. The Waterdrop can also be purchased in black or white, so you may choose to match your water filter to your pipes.

Performance of the Waterdrop

The Waterdrop uses just a single filter to complete a full five stages of the filtration process. This filtration process results in up to 99% of harmful contaminants being removed from the water, plus bacteria and most viruses. Targeted harmful contaminants include:

  • Lead
  • Chlorine and Chlorine byproducts
  • Mercury 
  • Chloramines
  • Cysts
  • Copper 
  • Rust 
  • Sand and other sediments
  • Worms

Meanwhile, the Waterdrop retains minerals essential to your body’s overall health. Calcium, potassium, sodium, and magnesium are all abundantly present in the human body and are necessary for proper function. As effective as the Waterdrop’s filters are, they are designed to ensure these helpful minerals remain in your drinking water.

During the first stage of the filtration system, a polyester membrane removes sediment and other large particles from the tap water that runs through it. This is followed by the activated carbon block filter removing Chlorine and other chemicals that negatively affect the water’s taste and odor. 

Throughout the third stage of filtration, the water works through the KDF layer of the filter. This layer removes heavy metals, harmful bacteria, and other microorganisms. Not only is this third stage beneficial for the final water product, but it also prolongs the lifespan of the filter itself. 

Fluoride is removed during the fourth stage of the Waterdrop’s filtration process. Finally, during the fifth stage, the Waterdrop descales the water. This unique stage allows the Waterdrop water filtration system to act more like a water softener, as it prevents the building up of limescale and other scale-causing minerals. 

Where other under-the-sink water filtration systems require multiple filters within a cartridge, the Waterdrop requires just one. Customers who have already begun using the Waterdrop report that this innovative five-stage filtration process is effective and that it produces water that is noticeably cleaner and better-tasting. 

The Waterdrop’s performance has also been tested and verified by NSF International and the Water Quality Association, both of whom have certified the Waterdrop. The Waterdrop boasts a water flow rate of .075 gallons per minute. This is one of the best flow rates on the market and does not result in a noticeable difference when compared to unfiltered water. 

Depending on the size purchased, the Waterdrop’s filter remains effective for 8,000, 16,000, or 19,000 gallons of water. Electricity is not required to operate the Waterdrop, making it a safe option for any household. 

Installation of the Waterdrop Direct Connect

The Waterdrop Direct Connect is an under-the-sink water filtration system that can be connected right onto a sink’s main waterline. Weighing just over three pounds and spanning 3.6 inches x 3.85 inches x 12.3 inches (about the size of a typical plastic water bottle), These specs make the Waterdrop an ideal choice of system for use in kitchens, bathrooms, and even small RVs. 

When you purchase a Waterdrop water filtration system, you will also receive everything necessary to properly install it. This includes the housing unit, the filter, and all required hoses. Most customers report that they were able to install their new Waterdrop easily, as there is no need to hire a professional plumber for installation. The entire installation process typically takes about three minutes — it’s that simple. 

The Waterdrop should only be connected to a cold water supply. An included ⅜-inch hose and converters allow users to connect the system to both ½-inch and ⅜-inch cold water lines and faucets. While many water filters require users to purchase and use a new faucet, the Waterdrop Direct Connect can be used with your existing kitchen or bathroom faucet. 

Very few reviews mention any sort of leaking or other issues. Still, the Waterdrop company offers excellent customer service via multiple channels. To reach Waterdrop’s customer service, Waterdrop owners may reach out via telephone, email, or website chat. A money-back guarantee is also offered on the device, as is a warranty.

Maintaining a Waterdrop Direct Connect Water Filter 

Anyone looking for an under-the-sink water filter that does not require a ton of maintenance or advanced planning would do well to consider the direct connect Waterdrop. Everything about the Waterdrop — from first installing it to turning on the faucet — is well designed for easy use. 

The Waterdrop’s single cartridge is the most obvious example of why this system is low maintenance. In the case of the mid-range Waterdrop, the filter can filter up to 16,000 gallons before it needs to be replaced. For the typical household, this means two years of maintenance-free water filtration. 

Replacement filters are very affordably priced, and can easily be purchased via Amazon or the official Waterdrop website. To replace a Waterdrop filter, one simply needs to twist the old filter out, and the new filter in. Replacing a filter usually takes less than one minute.

Frequently Asked Questions 

1. How often should I replace the filter? 

You should replace the Waterdrop’s cartridge every 8,000 to 19,000 gallons, depending on the Waterdrop model you purchase. For most households, the filter life span will be about one year to two-and-a-half years. The user manual for your particular model will specify which span to expect. 

2. How many gallons can the Waterdrop filter? 

The Waterdrop direct connect comes in three different sizes. Depending upon the size purchased, each Waterdrop filter is capable of filtering 8,000, 16,000, or 19,000 gallons of municipal water. These filters are incredibly effective; the smallest of the three sizes requires filter replacement only about once per year. 

3. How much do replacement filters cost? 

The cost of replacement filters vary by size but average about $30. 

4. Where can I buy replacement Waterdrop filters? 

Replacement Waterdrop filters may be purchased via Amazon or the Waterdrop company’s official website. 

5. Is the Waterdrop compatible with my kitchen faucet?

In most cases, yes. The Waterdrop will work with faucets that have a ½-inch or ⅜-inch female NPT thread. As long as this is the case, the Waterdrop will be simple to install and will work exactly as designed. 

If your faucet does not meet these criteria, the Waterdrop company suggests contacting them before purchase to ensure you are receiving the right equipment. 

6. Where are Waterdrop filters manufactured? 

According to the manufacturer, all Waterdrop products, including the Waterdrop Direct Connect Under-the-Sink Water Filter, are designed in the United States and manufactured in China. 

7. Is the Waterdrop under-the-sink filter NSF Certified? 

While a number of Waterdrop water filtration products are indeed NSF certified, the Waterdrop Direct Connect described in this review is not currently certified by NSF International. However, it is designed to meet NSF certification standards for NSF 42 and others. These standards include removing lead, removing turbidity (cloudiness), and removing Chlorine. 

8. Will the Waterdrop work with well water? 

No. Although the Waterdrop is designed to filter out sand and other sediments, it is designed to filter municipal tap water. 

9. Will the Waterdrop under-sink filtration system filter out pesticides and pharmaceuticals? 

This Waterdrop filtration system is not meant to filter out pesticides and pharmaceuticals, though some filtration of those substances will occur by design. If filtering out pesticides and pharmaceuticals is your priority, then the Waterdrop Under-the-Sink Reverse Osmosis filtration system is better suited to your needs. 

10. Does the Waterdrop remove Fluoride? 

Yes, the Waterdrop is designed to remove Fluoride from the water.

11. Does the Waterdrop remove total dissolved solids (TDS)? 

The Waterdrop under-sink filtration system is not designed to remove TDS from municipal water. If removing total dissolved solids is a priority, then the Waterdrop under-sink reverse osmosis system (RO) system is likely better suited for you.
