If you’re looking for a great deal this Prime Day on a product that will actually make a positive difference in your life, look no further than Waterdrop Filter’s reverse osmosis systems. Whether you have an older system or have yet to install one, this is a must-have upgrade that brings cleaner, healthier water directly to your tap.
We’re all doing our best to stay healthy, but have you ever checked the quality of your water? Tap water can be contaminated with germs and toxic chemicals, including chlorine, lead, arsenic, copper, and forever chemicals. By forcing water through a semipermeable membrane, Waterdrop Filter RO systems can remove the inorganic material that should never have been in your drinking water in the first place.
Installing an RO system is also a great way to help the environment by cutting down on your use of plastic water bottles. I live in an area with hard water, which has an unpleasant impact on the taste of my tap water. Rather than risking the consumption of microplastics and contributing more waste by loading up on water bottles, I made the decision to install an RO system in my home, and it’s been one of the best moves I’ve made as a homeowner.
With all of that in mind, let’s take a look at four incredible Waterdrop Filter RO systems you’ll find on sale for Prime Day at the best prices we’ve ever seen.
Waterdrop Filter X12 Alkaline Mineral pH+ Reverse Osmosis System
One of the best ways to ensure that every glass of water you drink is as clean as it can be is to install a reverse osmosis system under your sink. If you’re looking for the top of the line, you’ll find it in the Waterdrop Filter X12 RO System.
In addition to being sleek, well-designed, and capable of delivering purified water at a speedy 1200 gallon per day (GPD) flow rate, Waterdrop’s tankless system features 11-stage filtration with its 16-layer membrane to reduce the harmless chemicals we discussed above. In addition to purifying water, the system is designed to infuse your water with alkaline minerals like calcium and magnesium to strengthen your bones and even improve the flavor.
And if you’re worried about wasting water, don’t be – all of Waterdrop’s RO systems feature a 3:1 pure-to-drain ratio, which means they only use one cup of wastewater to produce three cups of filtered water. That’s triple the efficiency of most RO systems.
The cherry on top of this vital home upgrade is the smart digital faucet that comes with the system. You won’t have to guess whether or not the filter is doing its job, because the faucet will show you the total dissolved solids (TDS) in your water as well as the remaining lifespan of your filter. It’s no wonder the X12 has racked up dozens of 5-star reviews on Amazon.
When it comes to the system’s effectiveness, you don’t have to take our word for it, either. With NSF/ANSI standard certification, Waterdrop ensures that its RO systems meet strict public health standards and actually do what they say on the box.
As one of the company’s most high-end systems, the Waterdrop Filter X12 RO System retails for $1,299, but you can pick one up for the majorly discounted price of just $899 during Prime Day, which runs from July 2-13.
Waterdrop Filter G3P800 RO System
If you want to own the best-selling tankless RO system on Amazon, Waterdrop Filter’s G3P800 is the system for you. Depending on how many people are in your home, you might not need the capacity of the X12 system. That’s where the G3P800 comes in, featuring a similar tankless design, the same 3:1 pure-to-drain ratio, and a peak flow rate of 800GPD capable of producing a full cup of water in just 6 seconds.
With its 10-stage filtration, the G3P800 is also a must-have for the health conscious, heavily reducing forever chemicals, fluoride, heavy metals, and more. Plus, a built-in UV light turns on automatically whenever water flows by and sterilizes 99% of bacteria.
Despite the lower price, Waterdrop’s G3P800 RO system still includes a smart faucet to show you real-time TDS levels and water quality.
The Waterdrop Filter G3P800 RO System is already an unbeatable deal at its retail price of $999, but the tankless, under sink water filter system and its included smart faucet will only run you $699 if you buy one during Prime Day.
Waterdrop Filter A2 Instant Hot Cold Water RO System
Moving from under your sink to your countertop, we have the Waterdrop Filter A2 Instant Hot Cold Water RO System. If you don’t have room under the sink, you can still get clean, healthy, tasty water without the need for installation. Just place the A2 on any counter or table, fill up the water tank, and you’ll have purified water at your fingertips in minutes after it passes through the RO system’s 5-stage filtration.
What impresses me most about Waterdrop’s A2 RO system is its ability to quickly cool water down to 50℉ or up to 203℉. Whether you’re in the mood for a cool, crisp glass of clean water or plan to make a cup of tea or coffee, the A2 has you covered. Best of all, you can use the smart touch control screen to set your favorites, so that the perfect amount of water is always a tap away. There are 6 temperature options and 5 water volumes to choose from, which is a striking amount of customization for an RO system.
I’m also blown away by the brilliance of the water pitcher that sits comfortably at the front of the RO system at all times. Whether you’re looking to water your plants, fill up a pot on the oven for cooking, or just quickly pour a glass of water, the pitcher makes it easy.
I love my under-sink system, but being able to place an RO system anywhere in my house would be a game-changer. You can even take the A2 Instant Hot Cold Water RO System with you on road trips in an RV or plug it in while staying at a vacation rental home. The adaptability of this system is simply hard to beat.
You can typically purchase the Waterdrop Filter A2 Instant Hot Cold Water RO System for a cool $499, but for Prime Day, Waterdrop has lowered the price on its premium countertop RO system to $379. Try finding another countertop water filter of this quality for anywhere near the same price (spoiler alert: you can’t).
Waterdrop Filter C1H Instant Hot Water RO System
Finally, we come to the small but mighty Waterdrop Filter C1H Instant Hot Water RO System. While it’s the most compact RO system on this list, it’s also a fully capable countertop option, featuring 6-stage filtration, 3:1 pure-to-drain ratio, NSF certification, and the same RO filtration membrane as the tankless X12 system.
What sets the C1H apart is its cutting-edge heating technology, which allows it to heat up water in three seconds flat. The C1H offers five easy temperature options to choose from as well, each of which serve a specific purpose. For instance, choose 113℉ for oatmeal, 185℉ for coffee, or 203℉ for a cup of tea.
What the C1H proves is that you don’t need a ton of space to prioritize your health. It’s small enough to fit on almost any surface in your home, but still features a 110oz feed tank in addition to a portable 34oz pure water tank hidden beneath the cover. No home is complete without an RO system, and this might be the perfect one for you.
The Waterdrop Filter C1H Instant Hot Water RO System is already priced to sell at $299, but for Prime Day 2025, you can bring one home for $209.
