Frizzlife vs Waterdrop Review (Do NOT Buy Before Reading)

Frizzlife vs Waterdrop

Both under sink water filters are 99% effective at removing lead, chlorine, bad taste and odors, and other contaminants. The Frizzlife PD600 includes 7-stages of filtration and built-in TDS meter. The Waterdrop G3 has a slower flow rate, lacks an alkaline filter, and doesn’t remineralize the water.

It’s easier to register the product warranty and receive installation support by purchasing through Frizzlife’s Official Store. They also offer more periodic discounts that aren’t available on Amazon.

Under sink water filters works best for those who want pure drinking water and gallons of it right from their kitchen faucet. The Frizzlife Under Sink Water Filter and Waterdrop G3 both offer benefits to those who demand the best water filter, but which one has the highest filtration rate and filter life?

We take a look at the differences between these two popular under sink water filters, considering pros and cons of Frizzlife vs Waterdrop while also conducting thorough water testing.

About Frizzlife

While still relatively new to water filtration, Frizzlife has made a name for itself by being the brand known for home water solutions. Over the past 10 years, the water filtration brand has aimed to create the most effective and efficient water filtration systems that are also convenient for home use. One of their main products is the Frizzlife PD600 Under Sink Filter with Alkaline Remineralization. This water filter is one of the only products that includes filtration and pure alkaline features.

About Waterdrop

Founded in 2015, Waterdrop is another up-and-coming water filter brand that has created a variety of water filtration products. With a global partnership to improve water all over the world, Waterdrop has created over 200 water filtration products that include reverse osmosis filtration, water filter pitchers, whole house water filtration systems, and much more. Their Waterdrop G3 system is a reverse osmosis water purification product that offers a tankless design and smart TDS monitoring.

Frizzlife PD600 Undersink Filter with Alkaline Remineralization

The Frizzlife Under Sink Water Filter System is NSF/ANSI certified RO water filter and offers a high capacity, direct connect water filter that you can easily hook up underneath your kitchen sink. However, the best part about this system is its uncanny ability to detect and remove all kinds of toxins.

Frizzlife Under Sink water filter is 99.99% effective at removing lead, chlorine, odor, bad taste, bacteria, viruses, and many other contaminants.


The Frizzlife PD600 water filter is a tankless reverse osmosis filtration system that offers 600 gallons per day output and 7 stages of water filtration, which includes an alkaline remineralization filter.

Not only does this water filter have a fast output, but it’s incredibly pure. Our tests revealed the system reduced contaminants by almost 100 percent, and the water tasted incredibly pure and smooth, just like spa-quality mineral water.

Additionally, the integration of a smart TDS meter helps you see the quality of the water at any time. You also don’t have the problem of a huge tank or installing multiple tanks underneath your sink. It’s entirely tankless and easy to install right out of the box.

What We Liked

The Frizzlife PD600 offers 7 stages of filtration, which is almost extreme in the water filtration world. There are hardly any water filters of this caliber that offer so many steps of water purification. In many cases, it’s just 3 to 5 stages.

However, Frizzlife doesn’t just want to create clean, healthy water. They also want to provide the best water for your body, which is why it includes an ionizer component that creates perfectly alkaline water.

The remineralization filter is especially helpful because you get back the natural minerals like magnesium, potassium, sodium, and calcium that your body needs. Most water filters strip out these minerals just like toxins.

Additionally, we looked at the wastewater ratio to see how the tankless design compared to regular under sink water filters. The high water efficiency made it even more clear that Frizzlife has designed one of the best under sink water filters if you want clean, alkaline water any time from your kitchen faucet.

What Could Be Better

While this filter offers excellent filtration and some smart features, we were surprised to find that there wasn’t a smart faucet with filter life indicators. You’ll need to replace these every 6 months for the activated carbon filters, but the RO membrane likely will last for 1 to 2 years. It’s best if you look at the owner’s manual to see what filter life you should expect.

Waterdrop G3

Have you been looking for a sleek new water filter? The Waterdrop G3 is an under sink water filter that offers 7 stages of water filtration, including a reverse osmosis, CF filter, and CB filter.

The system claims to remove 99% of all contaminants, so long as they are larger than 0.01 μm. Additionally, the water filter was successful at removing bacteria and a few other micro-organisms. You’ll see a reduction in TDS, limescale, heavy metals, and other harmful toxins.

Waterdrop also created this model to be very user-friendly and easy to install. You can install the system within a few minutes and start using it for pure, tasty water. However, it doesn’t come with the same level of filtration or remineralization as the Frizzlife Under Sink filter.


The Waterdrop 7-stage under sink water filtration system comes in a sleek package. The design includes a black panel and its own faucet.

The sediment filter removes larger particles and impurities, while the UF filter removes hundreds of common contaminants. The CF filter is a powerful shield against chlorine, lead, and other heavy metals. The CB filter is a post-activated carbon block that reduces almost all toxins, and the RO filter offers three layers of DOW RO membrane, reducing micro-toxins.

The best feature of this system is the integrated waterway that allows you to make filter changes without ever having to turn off your water supply. The UF membrane also lasts up to two years, much like a reverse osmosis membrane.

What We Liked

With 3 stages of filtration and powerful filters, the Waterdrop G3 is a solid under sink filter that can do it all and quickly provide drinking water. While it doesn’t taste as smooth or high-quality as Frizzlife, it removes similar toxins, though we found it wasn’t as effective against some bacteria, viruses, and Chromium-6.

The innovative design does save a ton of space under your sink, and the filter life indicators will save you a ton of trouble. These filters are also designed to last a little bit longer than your typical filter, and there are less of them to change each year.

While the 400 GPD isn’t as fast as Frizzlife’s flow rate, it’s still incredible. You’ll get one cup of water in 12 seconds or less.

What Could Be Better

Waterdrop claims this is one of their smartest systems, but it’s really not that innovative. It’s just a reverse osmosis system that doesn’t have a remineralization filter, which means that your water won’t be as healthy or alkaline as Frizzlife’s results. Even though water quality is quite pure, more attention could be placed on the final taste and purity level.

Here’s Why We Recommend Frizzlife

Our Frizzlife PD600 review revealed most of the high-quality features included with this water filtration system. Without the remineralization feature, it’s only slightly superior in purification, but if you’re an avid water drinker or need alkaline benefits due to gastric issues, this is the better water filter to choose.

Both filters offer excellent filtration and smart features. Frizzlife has a higher flow rate, re-mineralizes water, and adds alkalinity. For those who don’t want to perform an installation or can’t modify their sink (apartment owners) Frizzlife also offers an effective countertop water filter.

The Frizzlife WA99 is a countertop water filter with reverse osmosis filtration. It’s WQA-certified and offers premium performance with the ability to remove over 1,000 contaminants. It’s also extremely portable and easy to set up. You can use it right out of the box without having to hook it up to any water faucets or lines. It also has one of the best wastewater ratios at 5:1, saving pure water and allowing toxins to drain out.

Other Frizzlife Reverse Osmosis Filter Benefits

In addition to our initial Frizzlife PD600 review, we conducted several tests to see how true the remineralization and alkaline stages are to the marketing materials. We found that every glass came in at a little above 7.5 pH, which is excellent alkalinity, though some like their water to be a bit higher in alkalinity for special cases. It’s safer to keep daily alkaline ingestion under 8 pH.

For those who haven’t tasted water from a reverse osmosis filtration system, you’re in for a real treat. These systems are designed to remove almost all toxins and hard minerals from your water. That’s why the remineralization filter is such a bonus to those who want pure water but don’t want to miss out on healthy minerals.

Smart Features

The Frizzlife water filter also comes with a few different smart features like a TDS meter display that shows you the quality of your water. This is especially helpful if you want to make sure your filters are working properly.

Easy Installation

The tankless, compact design makes this system easy to fit under the sink. You also don’t have to do very much work to hook up your system to water lines and start drinking pure water. Most customers report that it only takes minutes to set up the Frizzlife PD600.

Excellent Product Support and Warranty

All of Frizzlife’s products are covered under a warranty. If your system breaks within a year, your parts and replacements are covered. Their support is available via the website or by email.

Quick Filter Replacement

We also noted that the brand made it quick and easy to twist and replace filters within 3 seconds. It’s actually a unique design that makes it super simple, but if you have any issues, the company also provides several instruction videos and guidance online.

Should You Buy Frizzlife PD600 or Waterdrop G3?

While both of these systems offer 7 stages of filtration and DIY installation, you’ll get more use and healthy drinking water from the Frizzlife PD600. The combination of reverse osmosis filtration and alkaline remineralization offer the highest level of purification for your drinking water.
