Today we’re diving into a Waterdrop filters review. Waterdrop has gained immense popularity in just a few years since its inception in 2015, so it’s due for a thorough review of its most popular products.
I’ll analyze and break down Waterdrop’s best filtration systems in terms of filtration performance, technology, filter life, and durability in the following categories:
- Reverse osmosis filters
- Refrigerator filters
- Faucet filters
- Water filter pitchers
- Undersink filters
- Gravity-fed filters
- Portable water filters
This review will help you find the best Waterdrop filter that will transform your water quality from bland to grand. Let’s dive in!
Quick Summary
- Most Waterdrop filters are independently NSF certified.
- Waterdrop has a unique filtration system for every circumstance and need.
- Waterdrop is committed to using and combining the latest in filtration technology.
1. Waterdrop Tankless Reverse Osmosis System: $999
The Waterdrop G3P800 filtration system is what happens when you take Waterdrop’s best product, the G3, and mix in a little Captain America super serum for some kick.
How does it work?
The most significant feature I can tell you about this Waterdrop filter is that its new filtration process is light-years ahead of the other water filters in its class.
The new method includes nine filters, including a layer of reverse osmosis (RO) membrane.
The first layer consists of purification performance cotton, which can remove over a thousand harmful substances, including sand, rust, larger particles, and nematodes. The next layer features a scale inhibitor membrane that helps reduce water scaling in the usual trouble areas of your sink.
An activated carbon block layer acts as the next filtration layer and removes fluoride, lead, and chlorine. This layer is also responsible for improving the smell and taste of dirty water. The water then passes through another layer of purification performance cotton to catch any particles that may have slipped by.
Then comes the heart of the system, a reverse osmosis membrane that removes harmful contaminants larger than 0.0001 microns. That’s extremely tiny. Next, an activated-carbon block layer removes any chlorine or volatile organic compounds (VOC) present in the water as well as strange tastes and smells.
Finally, the water is treated with the new UV sterilizer, which effectively kills 99.9% of living organisms, and then is ready for consumption. Pure, fresh water!
Its 800-gallons-per-day filter capacity can handle even the heaviest of water drinkers. The RO filter will last 24 months, while the other two filter cartridges will need replacement every 6–12 months. The replacements will cost you around $198.98 annually.
When it comes to eco-friendly features, this reverse osmosis system has advanced water-dispensing technology, preserving 12 times more water than the traditional reverse osmosis systems, which produce significant amounts of wastewater. This RO filter creates only a cup of wastewater for every three cups of filtered water delivered.
One major thing Waterdrop filters are known for is innovative, interaction-based displays, and the G3P800 is no different. Its brand-new screen system allows users to view the working status and water quality. The filter display includes multiple smart functions, such as a filter life indicator, TDS indicator, and malfunction alert.
Pros:
- NSF 58 and 372 certified
- 90% TDS reduction
- Smart faucet included
- UV sterilization
- 800 gallons per day
Cons:
- Expensive
- Operates on electricity
- A bit noisy
2. Waterdrop 2-Stage Whole House Filter: $149.99
Waterdrop’s WHF21-PG whole-house filtration system can do it all. From filtering drinking water to reducing buildup in your washing machine, you won’t regret adding a Waterdrop whole-house filtration system to your household.
How does it work?
First of all, it’s essential that this model is installed correctly. While it’s generally easy to install, I recommend you hire your local plumber to help you with the installation if you’re not confident with your home repairs abilities. Otherwise it may end up leaking.
One end of the filter is connected to the main water supply, and the other end is linked back to the mainline that supplies the whole house. The water flows through a PP (polypropylene) filter first, and this sediment filter is excellent at catching larger contaminants like rust, dirt, sand, and grit.
Next, the water moves through a secondary GAC (granular activated carbon) filter. This stage removes sand or grit that may have slipped by the PP filter, as well as chlorine. The carbon filter is also responsible for eliminating strange smells and colors. It does only have two stages of filtration, which may not be sufficient for homes with extremely contaminated water.
Durable copper connections ensure that this system has better compatibility with other components and that it will last. The updated materials have a very premium feel to them. The reinforced structure now features long-lasting materials that have passed 100,000 water hammer and 300 psi water pressure tests. This filter comes ready to work.
The Waterdrop WHF21-PG filtration system comes equipped with up to 12 gallons per minute as its maximum flow rate. It can take on laundry machines, dishwashers, or steam machines and still deliver a quick pour from any available faucet.
You really want your whole-house filter to do its job effectively, delivering filtered tap water in a timely fashion. With a 12-gallons-per-minute flow rate, you’d be hard-pressed to find a quicker whole-house filtration system.
Depending on your water quality, each filter will last three to six months. As it nears its expiration date, the filter loses its cleaning efficiency.
Pros:
- Easy installation
- Affordable
- Copper connections
Cons
- Not certified
- Only 2 stages of filtration
- No filter-life display
3. Waterdrop Ultrafiltration Under-Sink Filter: $179.99
This under-sink water filtration system is a three-stage, high-capacity under-sink filter that can effectively reduce chlorine, taste, and odor while reducing fluoride, heavy metals, and more.
One of the most significant benefits of the Waterdrop TSU-B is it removes harmful contaminants and retains beneficial minerals, which provide safer and healthier drinking water for your home.
How does it work?
Waterdrop’s proprietary ultrafiltration membrane filters contaminants larger than 0.01 microns from your local water source. It also retains minerals you need, like calcium, magnesium, sodium, and potassium.
First, tap water passes through a pre-sediment filter. This filter reduces sand, rust, suspended solids, particulates, and other harmful impurities. This is great because all of that sounds horrible to drink.
Next, the water passes through Waterdrop’s advanced ultrafiltration membrane, removing many contaminants larger than 0.01 μm, like bromine, clay, and even radioactive fallout. We’re talking Blinky the Three Eye’d Fish, fallout. Waterdrop doesn’t say what its ultrafiltration membrane is made of, but they’re usually either ceramic or polymer.
Finally, the water passes through a carbon block filter. This is where Waterdrop adds its finishing touch, delivering ultra-fresh, great-tasting drinking water. It comes out of a dedicated faucet as tap water and is perfect for cooking or making great-tasting coffee.
The Waterdrop TSU-B’s advanced ultrafiltration membrane design has one of the longest filter lifespans of any under sink water filter, lasting 24 months before it needs replacing. Its polypropylene filter should last six months, and the carbon block filter will need changing in 12 months. If you purchase these replacement filters together, the total cost will be $94.
The fact that this filter has a lifespan of up to two years is a massive benefit for those looking to save some cash on maintenance fees. These days, who isn’t looking to save a buck or two?
Like many Waterdrop filters, the installation was a breeze, and I didn’t need to buy something else to make it work. This filter saved me a few bucks by not needing a handyperson to do it for me.
I’m a sucker for technology, and the indication system that comes with this Waterdrop filter allows you to check drinking water quality and working mode whenever you want. It also comes with electronic indicators that notify you when to switch out the filters by changing color, guaranteeing safe and healthy purified water 24 hours a day.
However, I did encounter some difficulty when trying to replace the filters. They didn’t come off easily, which is contrary to what the website suggests.
Pros:
- High-quality ultrafiltration
- 8-stage deep filtration
- Smart filter-life indicators
- Compact design
- Battery operated
Cons:
- Difficult filter replacement
- Not designed to remove TDS
4. Waterdrop 2.25-Gallon King Tank Gravity Filter: $249.00
This countertop water filter holds enough filtered drinking water to service an entire family and can be used indoors and outdoors, making it one of the most functional filters produced by Waterdrop. It can also function without electricity, making it the perfect option for those living an off-grid lifestyle.
How does it work?
The newest version of the Waterdrop 2.25-Gallon King Tank features updated filtration media. Its fluoride water filters use activated carbon and resin, which helps reduce fluoride and improve taste while ensuring water clarity.
The King Tank is a two-stage filter system with an upper and lower chamber. Dirty tap water is poured into the upper chamber, where it first passes through an activated carbon filter, improving the water’s taste and clarity.
Next, the tap water passes through the fluoride and resin filter, reducing — you guessed it! — fluoride. Fluoride is good for your teeth in small doses, but excessive fluoride levels can lead to tooth enamel decay.
The filtered water is then passed into the lower chamber, from where a spigot pours it directly into a cup or pitcher.
The King Tank also includes a free liquid level display, which is pretty handy. It installs effortlessly, and the display is clear and easy to read.
The storage capacity of this unit was massive. It lasted three days before needing to be filled up again. I’m guessing that even a family of four would have a hard time drinking this entire supply in one day.
Its carbon filter can last 6000 gallons, while the fluoride filter can filter up to 1000 gallons before needing a replacement. You can buy a pair of carbon filters for $58.99 and a fluoride filter for $44.99.
Many of these gravity-fed units are made of cheap plastic components. The King Tank, however, is constructed of strong stainless steel. If you’re planning to take this filter on the road, it will take a beating and keep on filtering.
My uncle Terry weighs 200 lbs., and this filter passed the “Can Terry sit on this without crushing it?” test. (What can I say? You make your own fun in the boonies.) FYI, the filter can withstand 220 lbs. in total.
Pros:
- Big water-holding capacity
- Strong stainless steel body
- Visible water spigot
Cons:
- Expensive replacements
- Not certified
- Does not remove TDS
5. Waterdrop Outdoor Portable Water Filter Pump: $39.99
Waterdrop filters can be counted on to feature a water filter for every occasion, and with its portable outdoor water filter pump, it offers a water filter that can go anywhere you need it to.
Whether you’re the type who lives an active, outdoor lifestyle or someone who works in an office building with a stanky water supply, the Waterdrop Outdoor Portable Water Filter Pump makes filtering water accessible for everyone.
How does it work?
Featuring three layers of meticulously tested filter media, this unit efficiently purifies up to 99.99% of harmful contaminants commonly encountered with well water and also natural water sources such as rivers and lakes.
The Waterdrop Outdoor Portable Water Filter Pump is no bigger than a standard water bottle. It works by filling the bottle with whatever natural water source is available. Once the bottle is full, the filter is inserted into the water, and the cap is firmly tightened, ensuring a water-tight seal.
This filter comes with a straw attached to the filter through a small outlet located on the cap. The straw is inserted into the outlet and pushed firmly into place. The pump on top is pushed, and the resulting pressure forces the dirty water through activated-carbon media, improving its taste and odor.
After passing through the carbon filter, the water flows through a ceramic filter layer consisting of nanometal clusters that intercept up to 99.99% of bacteria. The ceramic filter also reduces heavy metals, chemicals, VOCs (volatile organic compounds), and other dissolved solids.
Waterdrop’s portable water filter offers infant-safe product material, both lead-free and BPA-free, ensuring that no secondary pollution is added to your filtered water.
Designed for everyday life, this Waterdrop travel water filter withstands compression and trauma, making it incredibly tough. This portable water filter can handle extreme usage and is designed to last far longer than most portable water filters.
The sheer toughness of this portable water filter is worth the price of admission alone. You could drop this filter an unbelievable amount of times, and it wouldn’t even make a dent. You save cash in the future by erasing the need to buy filters repeatedly due to shoddy construction.
This filter can handle up to 1,320 gallons of water before you would even need to look for a filter cartridge replacement — by my horrible math, that’s close to forever.
Pros:
- Filters 99.99% impurities in well water or backcountry water
- Made of durable BPA-free plastic
- Long life
Cons:
- Doesn’t have certifications
- No way to indicate the filter life
6. Waterdrop Alkaline Chubby Filter Pitcher: $28.99
Waterdrop’s alkaline water pitcher is the best choice if you want delicious water with an elevated pH. It can remove 99.99% of contaminants in water, including chlorine and heavy metals.
With a decent water holding capacity of 10 cups, a sleek design with a wooden handle, and a lifespan of three months, the Waterdrop pitcher could be your best companion at home or while traveling.
How does it work?
The Waterdrop filter pitcher uses robust filtration technology comprising six stages. It includes activated carbon filters and meshes that trap chlorine, dust, dirt, and heavy metals like lead, zinc, and mercury. The filter also adds healthy minerals into water, like calcium, magnesium, sodium, and potassium, bumping the pH to 9.5.
I like the design of this Waterdrop pitcher. Unlike typical pitchers with open spouts that can allow bugs and dust to enter, this filter features a dust-proof spout and automatic water inlet. What I love the most is its filter life indicator, which shines blue and red to notify you of the filter’s condition. Additionally, the wooden handle makes it easy for anyone to grip the filter.
Waterdrop is designed to last up to three months and filter 200 gallons of water. But if your water quality is extremely poor, it can give up within a month. The replacement cost runs around $11.33, which is quite affordable.
Lastly, Waterdrop pitcher filters are NSF 42 and 372 certified for the removal of chlorine.
Pros:
- NSF certified
- Three months long life
- Affordable replacements
- Filter life indicator
- BPA-free plastic
Cons:
- Not for microbial contamination
- Expect frequent maintenance
7. Waterdrop Faucet Water Filter: $19.99
Looking for a durable point-of-use filter for your kitchen faucet? Waterdrop has your back. This faucet filter is NSF certified to reduce 94.2% of chlorine in your tap water.
How does it work?
Waterdrop’s faucet filter uses an activated carbon filter (ACF) to remove chlorine smell and taste in the tap water effectively. This technology is 10 to 12 times better than typical carbon filters.
You will receive simple instructions to install this unit onto your tap successfully. It took me less than 20 minutes to get it up and running. Keep in mind that it works on only standard faucet designs and not on taps like pull-out, hand-held, or spray style.
The Waterdrop faucet filter is designed to clean 320 gallons of water before needing a replacement. Although the filter itself doesn’t have a way of indicating its remaining life, Waterdrop offers to send you text reminders about the filter’s status. If you aren’t already tired of your phone buzzing every minute with endless notifications, you can opt for this.
Lastly, it is NSF/ANSI certified against standards 42 and 372 for chlorine removal.
Pros:
- Certified for chlorine removal
- Long life
- Easy installation
Cons:
- It’s not designed for TDS removal
- Poor build quality that lasts a year max
- Only fits standard faucet styles
8. Waterdrop Refrigerator Replacement Filters: $14.99–$70.00
Fridge water filters are still a thing, and Waterdrop can provide replacement refrigerator water filters for many different types.
How does it work?
The filtration process of a fridge filter isn’t complicated, especially if your fridge is already hooked up to a water line.
Once the water is connected, it flows into the fridge, through the refrigerator water filter, and then through to a chilled storage unit within the refrigerator.
Most models feature premium activated carbon fiber as filter media but not all Waterdrop filters are the same, so check your manual first to see what your replacement filters consist of.
These filters feature activated-carbon fiber technology, producing tasty and fresh water. A bonus is that fridge filters usually deliver ice-cold water for those who hate having to drink room-temperature water.
Although they don’t usually feature multi-stage filtration, refrigerator water filters can still be an effective drinking water filtration solution.
The most significant benefit of replacing your refrigerator water filter is that your filtered water is cool and refreshing pretty much all of the time. Unless there’s a power outage. Then you’re out of luck, Jack.
Pros:
- High-quality carbon filters
- Varying prices to suit your needs
Cons:
- Short life
- Is only good for removing chlorine in water
Methodology
This section will quickly walk you through the steps I took to review each Waterdrop filter.
Step 1: A list of Waterdrop water filters
The first step was simple. I went to Waterdrop’s website and noted all the models they were offering in the categories of whole-house filters, faucet filters, under-sink filters, pitchers, portable filters, refrigerator filters, and gravity filters.
Step 2: Product analysis
This step involved learning about Waterdrop’s filtration technology and how it compares to other brands. I turned to Google to discover which pollutants common filters can remove from both well and municipal water.
I also asked questions like what flow rate one should expect from whole-house filters, how long water filters should last, and what certifications a water filter must have.
Step 3: Online reviews
This part was a bit boring because I had to read many customer reviews of Waterdrop filters on trustworthy websites like TrustPilot, Consumer Reports, and Angie’s List. However, by the end of it, I had gained a lot of knowledge about various models.
I also learned how to distinguish real reviews from fake ones.
Step 4: Interviews with real customers
As the name implies, I reached out to a few customers and found out about their experiences with Waterdrop. Some were really satisfied with their units, while others returned theirs the next day. I jotted down all the good and bad points about the units they had.
Step 5: Interview with Waterdrop
Of course I wanted to evaluate Waterdrop’s customer service. I got in touch with representatives and posed a few tough questions about certifications, warranties, and product quality. They were friendly and helpful the whole time.
Step 6: Test drives
My favorite part of the research! I rented some filters and bought others to try them out. It took three months. I tested each unit to see how well they removed contaminants, their performance, flow rate, and how easy they were to install. I made sure to test the filtered water to see how well each unit actually purified water.
This really helped me figure out the best Waterdrop products.
Step 7: Ratings
Now that I had all the necessary information to rank the products, I used a spreadsheet. I entered all the details and assigned scores to each unit based on the following characteristics:
- Test results
- Performance
- Durability
- Filter design
- Filter cost
- Ease of maintenance
- Ease of installation
- Flow rate
- Customer reviews
- Certifications
