Exceptional Water Purification System with Outstanding Performance
I was blown away by the Waterdrop TSA Under Sink Water Filtration System’s ability to reduce PFAS, PFOA/PFOS, fluoride, chlorine, and bad taste and odor from my tap water. The installation process was relatively straightforward, and the filter’s compact design fits perfectly under my sink. I’ve been using it for a year now, and I can confidently say that the water tastes cleaner and fresher than ever before. The NSF/ANSI 42 certification gives me peace of mind, knowing that the product meets rigorous standards for quality and performance. In my experience, this system has been a game-changer for our household’s water quality, and I would recommend it to anyone seeking a reliable and effective solution.

Great value, easy install. Works great!
I moved into a new unit a few months ago and my water quality was horrible. It tasted like hard water and chemicals. I installed this (it was very quick and simple) and now my water taste amazing!! It removed all undesirable taste!Very happy with this product.

Got water that smells or tastes like chemicals? Get this NOW!
Design is great and it was super easy to install. The ability to quick connect the main body makes this a no brainer. I have horribly chlorinated water here in the PNW, and it clears out any smell or taste of chemicals without sacrificing water flow too much. Overall its a great product and it works as intended without breaking the bank.

Very Happy
This Waterdrop filter system yields clean, fresh-tasting delicious water.There’s no residue or foul taste from the city water.It took about 15 minutes to install with the faucet.Highly recommend.EDIT:Downgrading from 5-stars to 4 now that I’ve had this filter for 8 months.There are no automatic features on this water that tells you WHEN the filters need to be changed.You have to use your own judgment.Filter change time-frames are as follows:PP – 6 mos.GC – 8-12 mos.CM – 18 mos.Any bowl or a pot that “sits” with the filtered water in it has a white ring around the perimeter.I’ve emailed and called Waterdrop about this numerous times, but got no response.Today, I decided to downgrade my review from 5 stars to 4, when I saw the white rings again on a stainless steel pot and my pet’s water bowls.The water TASTES fine but I’d like to know what the “white” residue is.Is it calcium? Whatever it is, it should NOT be there.

The quality of water has improved markedly.
The filter is compact and easy to install. But there are also problems, I had to buy an additional flexible court to connect the water.

Prepare yourself for an aggravating situation
I bought this system to replace my older single filter Waterflop system which blew out and flooded my kitchen. After all, now I can have three filters that can blow out and flood my kitchen. Anyway, you would think Waterdropâs hoses/fittings would be standardized. Makes sense, right? Nope. The new metal hoses do not work with the faucet that came with the original Waterdrop system I installed 2 years ago. Those water lines were white plastic with quick connect connections. These new ones are like the hoses you get at the local hardware store, save for those funky connectors that go into/out of the filter itself. You will need to either a) get an adapter or b) purchase the DM-100 Vmasstone faucet (that comes with a variety of adapters for different R/O and water filter systems.). I bought the new faucet, which by the way is sturdier than the Waterdrop system.Problem #2: the new inlet hose didnât work with my T-splitter that I used for the old system. So I had to buy a new T-splitter. What I needed to get was a double female connector to hook up the inlet to the new T-valve. So now I am waiting on that to get here. Not happy.After multiple trips to the useless local hardware store (they sell everything no one needs) I called Waterdrop and was on hold waiting for 15 minutes. When the rep answered, as soon as I heard him speak I knew we were going to have a problem. His solution was to send me plastic tubing so I would be running a metal hose in and plastic tubing out. Thatâs not a solution. Thatâs called cutting corners. Not acceptable. Waterdrop is aware of this problem and youâd think they would throw in adapters for people using their old faucet so they donât have to spend more money to buy hardware to make this thing work.Trying to install this system has been nothing short of a nightmare. I previously ordered this system then cancelled the order. Changed my mind and reordered it and am so annoyed, I want to box this crap up and send it right back. They sell this on the premise that people all have the same plumbing set up which is a faucet with two spigots, one for hot, one for cold. My set up is not like that. I have a faucet and a single handle hot/water spigot that pivots to change hot to cold and vice versa. This is why I need the T-valve splitter. Also the line from my dishwasher is plumbed into the main water line. Itâs obvious the people at Waterflop never considered plumbing is not one size fits all. I have spent almost $100 on fittings/adapters/faucet/connectors to make this system work in my home. Iâm thinking I made a mistake. Please be aware that installing this system is not as easy as you think. Also, itâs absurd that Waterdrop doesnât include a faucet with this filter system. If you buy the one for Washington DC, you get a faucet. I donât live in DC and I had a Wayerdrop faucet that wasnât compatible with this system because thereâs no adapter for the new hoses. Youâll have to buy that separately.The only reason why I did not buy a real R/O system is because I am limited on the space under my sink. Thatâs unfortunate because those would probably be less of a hassle to install.

Good system & support
I’ve been using this filtration system for about a month now. It was easy to install an I’m very satisfied thus far with the performance. I’m especially pleased with the customer support at Waterdrop. I’ve called with several questions about the system both before purchasing and after installation. Most recently spoke to Martin on filters. I feel the company will be around for awhile and nice to have a real support person to talk to.
Amazon Customer –
Fit under the sink easily and was very easy to install. Cleaned up the colour and taste of the water. Water flow was reduced but not enough to be concerning. It will reduce the cost of buying bottled water.

Avevo bisogno di un filtro per l’acqua, e ho deciso di provare questo. Il prodotto è arrivato ben imballato, e anche il montaggio è stato semplice. Se avete problemi con le viti, io ho acquistato sempre qui su amazon ganci adesivi e regge benissimo, inoltre acquistate un altro tubo che va dal lavandino, che verrà collegato al tubo uscente dal filtro e una valvola a 3 vie.Per quanto la qualità dell’acqua, si sente la differenza, è molto più limpida e il sapore è migliore.

Ich habe das **Waterdrop TSA Untertisch Wasserfiltersystem** gekauft, um die bereits gute Wasserqualität in Aachen, NRW, weiter zu verbessern. Die Installation war dank der gut beschriebenen Anleitung und des unterstützenden Videos einfach und schnell. Ein wichtiger Hinweis: Achten Sie darauf, die beiden Zuläufe korrekt anzuschlieÃen, da ein erneutes Herausziehen schwierig sein kann. Das System muss vertikal montiert werden, um optimal zu funktionieren, nimmt aber dennoch wenig Platz im Unterschrank ein.Nach der ersten Inbetriebnahme fiel mir auf, dass das Wasser morgens zunächst nicht ganz so kalt ist, da zuerst das im Filter befindliche Wasser durchflossen werden muss. Ich lasse daher morgens den Filter einmal durchlaufen und fülle anschlieÃend Glas- oder Stahlflaschen für den Tagesbedarf, um Plastik zu vermeiden. Insgesamt bin ich sehr zufrieden mit dem Filter und kann ihn jedem empfehlen, der sein Trinkwasser zusätzlich aufbereiten möchte.Bleibt gesund und trinkt gutes Wasser (am besten ohne Kohlensäure!).

Jâavais le petit filtre avant, mais ce nâétait pas assez puissant pour stopper de consommer lâeau en bouteille, malgré de la même marque. Par contre avec ce filtre, grosse différence, fini lâeau en bouteille, lâeau a un bon goût, sans goût des produits chimiques, câest vraiment top. Lâinstallation était simple et facile.
