Households wanting deep under-sink RO filtration
The WaterDrop Ed61 Rechargeable Water Filter Dispenser is an under-sink RO system for those wanting high-quality water without countertop clutter. I was drawn to its contaminant reduction claims and rechargeable battery. The Ed61 fit neatly under my sink and served our family's daily needs, from filling bottles to cooking. I tested it over several weeks to see if it could keep up with our busy routine and how it compared to pitcher and countertop filters I've used before.
In daily use, the Ed61 delivered crisp, clean water that noticeably improved the taste of drinks and meals. The RO filter cut chlorine taste and odor, and the water looked and smelled fresher. My family drank more water, and even our kids noticed the difference. The flow rate was steady-about 30 seconds for a standard bottle-which I found reasonable for the filtration quality. Ice cubes made with Ed61 water were clearer and didn't pick up freezer odors. The system kept up during busy times without drops in flow or quality. Overall, it outperformed pitcher filters and made it easy to stay hydrated.
I installed the Ed61 in my kitchen and used it as our main water source for two weeks. I compared water taste, clarity, and odor before and after, using both taste tests and at-home test strips for chlorine and TDS. I timed the flow rate for bottles and pots, and observed performance during busy times. I also tracked filter changes and battery recharge intervals. The filtered water was used for everything from making baby formula to rinsing produce. I kept notes on refills, recharging, and any issues. This hands-on approach showed how the Ed61 fit into daily life compared to other filtration systems I've used.
Installing the Ed61 took about an hour. The instructions were clear, and plumbing connections were straightforward with a wrench and some patience. Color-coded tubing and labeled connectors helped avoid mistakes. The rechargeable battery meant no wiring was needed. I had to temporarily move a shelf, but the compact design fit well. The included faucet matched my kitchen, and the template made drilling easy. For a DIYer, installation was manageable-just double-check for leaks before finishing.
Maintenance is mainly timely filter changes and occasional cleaning. Filter replacement is a simple twist-and-pull process, and the system gives reminders. The filter compartment is easy to access, and I didn't need special tools. Replacement filters are an ongoing cost but easy to order. Cleaning the exterior is quick with a damp cloth. The battery held its charge for weeks; recharging took a couple of hours and didn't interrupt water flow. Indicator lights made it easy to keep up with maintenance, which was much simpler than refilling pitcher filters.
After several weeks with the WaterDrop Ed61, I'm impressed by its filtration and unobtrusive design. The water tasted better, and the system's steady performance made it easy for my family to stay hydrated and enjoy cleaner water in cooking. Installation and maintenance are approachable for most DIYers, though you should budget for replacement filters. The rechargeable battery and under-sink placement make daily use seamless. I especially liked not having to refill a pitcher or deal with countertop clutter. The Ed61 strikes a good balance between performance, upkeep, and convenience. Reminders for filter changes and battery charging remove the guesswork. I'd recommend it to households wanting a reliable, space-saving water upgrade.

As a reverse osmosis system, the Ed61 is designed to reduce a broad range of contaminants, including fluoride. Actual reduction depends on your water and filter condition. Testing before and after installation is recommended if fluoride removal is a priority.
In my experience, the battery lasted several weeks of daily use before needing a recharge. Charging is simple and doesn't interrupt water flow, so it's easy to fit into your routine.
