Our FAQ section covers everything from filter lifespan to installation tips for clean, pure water every day. Contact Us How does the dual-flow feature benefit me? You can switch instantly between standard RO-purified water for everyday drinking and an alkaline stream that adds beneficial minerals, perfect for coffee, tea, or anyone who prefers a smoother taste profile. Does the system keep water hygienic after filtration? Yes. Each water line has its own UV LED sterilizer that continuously disinfects the water as it leaves the filter, safeguarding freshness all the way to the faucet. Does it require a storage tank? No. The compact, tankless design prevents secondary contamination and frees up about 70 % more under-sink space compared with tank-based RO systems. Is installation complicated? No! The tank-free design make under-sink installation straightforward for most homeowners — no bulky tank to position or maintain. Will the alkaline stream affect beverage flavor? Yes — positively. The mineral-enhanced line can improve the taste and aroma of coffee, tea, and cooking water while still delivering contaminant-reduced purity. MORE CLOSE

This company has the worst, most incompetent customer service. I originally ordered two TST machines. Upon installation, the water was not cleaner. I contacted customer service and they said if I wanted clean drinking water, I needed the T4 reverse osmosis machines. I confirmed with them that if I ordered these machines I would not need an additional faucet to be installed, that I could use it with our existing faucet. They charged me an extra $42 which was the difference between the two TST machines and the 2 T4 machines. They sent me one additional TST machine and no T4 machines. I contacted them regarding this error and they did not get back to me for over five days. So I purchased the T4 machines myself directly on the site again. A day later they shipped out two replacement T4 machines without communicating with me. So in total I would had seven machines. I told them I did not need their other machines because I had already purchased them because they did not answer me back for a period of time. It took multiple days and emails back-and-forth to get return labels for the machines. I sent five of the machines back because two of them had not been delivered yet. They only credited me for three machines and did not refund me for the other two that I returned and that were delivered back to their offices with confirmation. I contacted them yet again and they were confused and did not know what I was talking about, so I had to call the bank and dispute the charges. I told them they still didn’t send me two return labels for the two machines that I had. They did not know why I wanted to return all the machines. I reminded them that they told me I could use them with my existing faucets and I couldn’t - I was not going to drill holes in my marble countertops for machines that may or may not work. The machine itself might not be bad, but I wouldn’t know that because the customer service was such a disaster that I never got that far. All I needed were two machines and over the course of two months they sent seven machines and it was a headache trying to get everything resolved and sent back and refunded to my account. During this time I was also sent to multiple customer service agents because no one knew how to simply send the correct machines or refund labels. I would not recommend this company, no matter how good or bad their units might be.

Hi, the unit was delivered fast. Easy to install, we replaced an old unit, so did not have to drill holes for water outlet or faucet. Water tastes great. Flow is slower than old unit but that is not a big thing.

Entire mounting bracket feels cheaply made, Haphazardly put together and just cheap. Push fittings were loose right out of the box. 2 leaked immediately. Took 3 reseatings to get them to stop. Must constantly monitor to make sure it's not leaking. Pump motor is loud. Water tastes good. Kids don't complain

We had it for about 2 weeks, and my wife and I really enjoy Waterdrop purifier. It functions well and water tastes is fantastic, even better than our favorite bottled water. We are already buying less bottled water.

One of my best investments! I have unlimited clean water for my family. My TDS water tester is reading the pure water at an 11 down from a 225. And I'm proud of myself for installing it. I had my countertop guy drill a 1" hole he charged me $40.
