5 Waterdrop Best Filters Reviewed


Let’s put the spotlight on the best-selling Waterdrop filters in the market today.


First on our list is the widely-claimed #1 RO system from the brand, the G3 Reverse Osmosis System. It has a sleek design that perfectly fits underneath your sink to provide you with purified water daily.

With a flow rate of 400 gallons a day, it claims to remove 99% of any toxic contaminants in your water. It does this through the 7-stage deep filtration technology, with smart technology that keeps an eye on the system on your behalf.

The unit also has a quick and easy installation in under 30 minutes, with the filter replacement process in as fast as 3 seconds. Another good thing to note is that: you won’t need any special tools to set up the unit.


The Waterdrop G2 model is another excellent option to consider. It is notably smaller (with fewer features) than the G3, but it’s a solid filter system to consider for tiny homes. It is equipped with a 5-stage filtration technology that can get rid of over 1,000 contaminants, giving you 400 gallons of purified water daily.

The unit is also cheaper than the G3, giving you great value for your money. (Related: How Much Does Reverse Osmosis System Cost? (2022 Buying Guide))


This next Waterdrop option is an under-sink water filter without the RO technology. It leverages a 3-stage filtration system (with a notable 0.01-micron ultrafiltration membrane) to filter out any contaminants in your water. This compact unit perfectly fits under the sink and is suitable for RVs and other small living spaces.

Most filters can last you for up to 24 months, eliminating the need for frequent replacement after 3-4 months like that of standard units. Although the unit lacks reverse osmosis filtration, it’s still an effective water filter with reliable filtration ability. Check out this unit if you’re not too particular about RO purification.

Waterdrop’s water filter pitcher is also worth considering– as it features a 7-layer filtration, a gravity induction indicator (to signal it’s time to replace the filter), and a sleek design that fits in your refrigerator door.

You can also count on the longevity of this pitcher, with most filters lasting up to 3 months or 200 gallons. Its robust filtration process also eliminates the strong odor and taste of chlorine, fluoride, lead, and other common contaminants in the water. The premium activated carbon fiber also boosts surface area and gives you better adsorption.


It’s hard not to be impressed by this next Waterdrop filter when it can filter up to 600 gallons of water per day. In particular, it doesn’t come with tanks, so you can expect the filtration process to happen in real-time.

Once the tap is turned on, the filtration process begins. The absence of a tank protects you from the possibility of a bacteria build-up and gives you space-saving benefits. This unit also makes it easy to glance at the TDS level and the remaining filter life through the screen near the filter system’s output faucet.

Benefits of Water Drop Filters


Here’s what to expect in Waterdrop’s filter products.

  • Multi-Stage Reverse Osmosis Technology: If you’re wondering what exactly sets Waterdrop models apart from other options in the market– you need to pay close attention to their unique reverse osmosis stage. In particular, both G3 and G2 models leverage multi-stage filtration through a proprietary reverse osmosis membrane. This effectively removes microparticles in the water and improves the alkalinity. RO membranes claim to filter out 99% of toxic contaminants. Both G3 and G2 are known to remove a wide variety of toxins (over 1,000) to ensure you’ll have pure, good-tasting, alkaline water.
  • Durable Filters: In selecting a filtration system, always keep an eye out for its expected filter life. Standard water purification systems need routine filter replacement every 3 to 6 months. Since Waterdrop is designed with multiple filters, you will only need to replace the composite filter annually. Meanwhile, the RO membrane is suitable for 2 to 3 years of use.
  • Hassle-Free Maintenance: Waterdrop filters have a tankless design, so you won’t have to deal with mold or mildew-related problems in the long run. Its plug-and-play filters make it easy to keep the unit clean without disassembling the case.
  • Consistent Support and Extended Warranty: Long-time customers note how consistent Waterdrop’s online and phone support is. If you’re facing any problems or need to ask relevant questions, you can quickly get in touch with their customer support online and by phone. Additionally, every purchase is covered with a warranty (filters and system). Composite filters have a 1-year warranty, while the reverse membrane filter has a 2-year coverage.
  • Installation is a breeze: You’ll discover other under-sink water filters usually take long hours to install with their multiple lines– but that’s not the case if you choose Waterdrop filters. On average, it will only take you as little as 15 minutes to install most filtration systems. You don’t need any plumbing experience to install the filters too, and you’ll have all the necessary tools you need on hand.
