This Prime Day, Waterdrop Filter is making it absurdly easy—and surprisingly affordable—to get clean, healthy water straight from your countertop, under-sink, or gravity-fed dispenser.

We’ve rounded up three of their top-rated filtration products—each with unique superpowers—to help you finally ditch bottled water and enjoy pure hydration with real peace of mind. Plus, with up to $700 off during Prime Day, now is the moment to upgrade your water and upgrade your life.
Waterdrop WD-A2 Countertop Reverse Osmosis System
For renters, offices, and anyone short on time, tools, or under-sink access
Let’s be honest—most countertop RO systems either look like awkward water coolers or require more setup than assembling IKEA furniture. Not the Waterdrop WD-A2 Countertop Reverse Osmosis System. This sleek, bottleless, plug-and-play system is basically the Swiss Army knife of hydration. It doesn’t just purify your water—it dispenses it at your ideal temperature with one-touch smart controls and no plumbing required.
Key features worth sipping on:
- 5-Stage Filtration Superpower: From chlorine and fluoride to heavy metals like lead and arsenic, the WD-A2’s 0.0001μm RO membrane zaps contaminants and even handles stubborn PFAS like PFOA/PFOS.
- Hot or Cold on Demand: Chill your water to 59°F or heat it to a tea-ready 203°F. Yes, you can now make instant noodles or sip cold lemon water from the same machine.
- Touchscreen + Favorites Mode: Set your go-to temp and water volume once, and the smart screen remembers it next time. Hydration habits = automated.
- No Plumbing, No Stress: The WD-A2 fits anywhere with an outlet. Think tiny kitchen, yoga studio, office cubicle, or even your campervan.
- Eco-Friendly and Wallet-Wise: With a 3:1 pure-to-drain ratio, this unit saves 1200% more water than traditional RO systems, while eliminating your bottled water costs.
Final Verdict: For anyone looking to level up their hydration game without busting out a toolbox, the WD-A2 is the ultimate kitchen (or office) sidekick. It’s sleek, smart, and ridiculously convenient.
Waterdrop Gravity-fed King Tank System
For off-grid adventurers, disaster prep kits, and the “I don’t trust tap water” crowd
Meet the Waterdrop Gravity-fed Water Filter System, aka the King Tank. This is your go-anywhere, no-power-required, 2.25-gallon stainless steel beast that’s ready for both emergencies and everyday hydration.
Certified to NSF/ANSI 42 & 372 standards, it’s a real performer—filtering chlorine, particulates, and heavy metals, all while looking like a high-end kitchen appliance.
Why it’s royalty in the gravity filter world:
- Big Capacity, Small Footprint: 2.25 gallons is perfect for families, group camping trips, or your weekend cabin. Just fill and flow—no electricity, no plumbing.
- 304 Stainless Steel Durability: Rustproof, dent-resistant, and ready for decades of use. It even includes a metal water level spigot and two height-adjustable stands.
- Anti-Skid Design: Safe around kids, pets, and clumsy adults. Your hydration station stays upright, even on bumpy surfaces.
- Heavy-Duty Build: Withstands up to 220 lbs of weight—this thing is tank-tough.
- Perfect for Multi-Use: Great for kitchens, RVs, offices, outdoor events, or emergency kits. It’s the “everywhere water filter.”
Final Verdict: If you need a power-free, heavy-duty water purifier that looks as good on a countertop as it does in a field tent, the King Tank’s your guy. Bonus: it won’t scream “emergency prepper” to your dinner guests.
Waterdrop X12-Alkaline pH+ Undersink Reverse Osmosis System
For families who want pro-grade filtration with zero countertop clutter
If you’re ready to commit to next-level hydration, the Waterdrop X12-Alkaline Mineral pH+ Reverse Osmosis System is the clean-water powerhouse your kitchen deserves. It’s quiet, tankless, stylish, and smart enough to tell you exactly how much water you’re using—and how clean it is—through a digital faucet screen.
What makes it the MVP under your sink:
- 1200 GPD Flow Rate: This isn’t your grandma’s trickle filter. The X12 fills a glass in seconds and powers your coffee machine, kettle, or water bottle without delay.
- 11-Stage Filtration + Alkaline Minerals: With 16 layers of filtration, it scrubs out the nasties (TDS, PFAS, fluoride, lead, arsenic), then adds back healthy minerals like calcium and magnesium. Balanced pH? Check.
- NSF/ANSI Certified: Tested by SGS and IAPMO R&T, this system meets the gold standard in filtration safety and performance.
- Smart Digital Faucet: Choose precise volumes, monitor TDS levels in real-time, and get notified when it’s time to change a filter. Water just got a brain.
- Space-Saving + Eco-Wise: No bulky tank and a sleek wall-mountable design that fits neatly under your sink. Plus, the 3:1 pure-to-drain ratio means less water waste and lower bills.
Final Verdict: The X12 is for serious water nerds and growing families alike. With its speed, smarts, and sustainability, it’s a future-proof investment in your health and your home.
