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.

Water drop triple filtration water system
Highly recommend this product don’t know how we lived without it before.Does everything it says it does and you will be amazed by the taste of your water you think your average filter does a good job this thing makes water taste like it’s supposed too.First thing you’ll notice is no chemical chlorine smell.Easy to change filters. They’ll know when it’s time to change your filters when your water flow gets a little slow . Filters are relatively inexpensive. And not having to change all three at once is a plus . Perfect size to fit underneath your sink doesn’t take up too much space tucked away on the side or the back of your cabinet. I used to spend five bucks a day for a gallon of water not anymore. Way better than any bottled water you can buy.

Best water filter and customer support
Waterdrop filters are one of the best filters available which are effective and affordable. I took it specifically for chlorine and other impurities.I took waterdrop filter about 1.5 years ago. I changed the first stage filter and the water stopped working. I contacted customer support and they sent me first and second stage filter at no extra cost. But that did not work. The issue was with the unit. So they sent me a new unit with filters to fix the issue.Andrew from customer support was very knowledgeable. He understood the issue and made sure it’s resolved with minimal communication.

customer service
Product has been working great for the past 8 months. Was very easy to set up and use. I had a bit of waterflow issue after 6 months or so but I contacted the team and Rebecca was able to help me. Great product and customer service

Excellent replacement for rip-off “American” systems
Got this to replace my RAINSOFT Hydrefiner II after they tried to extort $400 for a simple replacement of two filters! The RAINSOFT system started exhibiting the same low-flow issues you see in some of the reviews here — that means your filter needs to be replaced as the membrane is so swollen it is no longer allowing water through.As RAINSOFT customers well know — RAINSOFT locks you into proprietary purchasing — you can’t get replacement parts, under some flimsy notion that they need to meet expectation yards-yadda — it’s all made in China! Their “factories” are nothing more than a person in some warehouse somewhere receiving shipments from China.So what pay 400% of the price of something you can get for… normal price?Made the easy choice — after checking that replacements would be available — and never happier. The water passed the kids-n-wife test too — thumbs up all around.I did have to order an additional John Guest attachment to use my existing connections — a simple enough feat for any truly red-blooded American.Photo included to show that you too can install a simple John Guest elbow and John Guest T-splitter to provide water for your refrigerator AND sink tap!

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.

I recently installed the Waterdrop TSA Under Sink Water Filter System, and it has exceeded my expectations in every way. This 3-stage high-capacity water filtration system delivers pure, great-tasting water right from my kitchen sink, making it a fantastic addition to my home.Installation was straightforward, thanks to the detailed instructions and included hardware. Even with minimal DIY experience, I was able to set it up without any issues. The compact design fits neatly under the sink, taking up minimal space, which is a big plus for those with limited cabinet room.The filtration performance is exceptional. The 3-stage system effectively removes chlorine, heavy metals, and other contaminants, leaving the water clean and safe to drink. The improvement in taste and clarity is noticeable immediately. It’s reassuring to know that my family is drinking high-quality water without any harmful impurities.One of the standout features is the high-capacity filters. They last a long time before needing replacement, making the system low-maintenance and cost-effective in the long run. The easy twist-and-lock design of the filter cartridges makes changing them a breeze, further enhancing the user experience.Additionally, the water flow rate is impressive.
