Waterdrop CTF-03 Alkaline Water Filter for Sink Faucet, NSF/ANSI 42 Certified Countertop Water Filter System, 5-Stage Stainless Steel Faucet, Reduces 99% Chlorine, 8000 Gallons, 1 Filter

It been almost a year since I bought this. My whole family loves it and it has saved us a lot of money. Also less plastic. The water is great and taste very clean. It also was very easy to install.

Works Great delivers The alkaline water beautifully tests out as true filtered alkaline water 8000 gallons worth per filter high-quality solid stainless steel. I’m very happy with this filter and the company does make high-quality product. You’ll be happy with whatever filter you get from them. I love this one because it’s just me and my son who is in college visiting once a month. I use it for my coffee each morning and my filtered bottled water from home about 2 1/2 gallons a day at most I’ve been very happy with it the past six months.

I genuinely wanted to love this product, but unfortunately, it didn't meet my expectations. I was excited to receive it due to our family's high water consumption, but to my surprise, the filtered water tasted worse than the tap water. I’m puzzled by how that could happen, and I’m still on the lookout for a countertop filter that actually works. Update I had initially provided a disappointing review of the product, but then received an email from the customer service representative, Harper. Harper was very responsive and proactive in trying to resolve the issue I had experienced. They offered to send me the Waterdrop Flash Powerful Countertop Water Filtration System as a replacement. Harper stayed in constant communication with me, answering any questions I had, until I received the new item. The level of customer service provided by Harper was excellent - they went above and beyond to ensure my satisfaction. The new water filter I received was much better than the previous ones I had purchased. It produces water that tastes significantly better. I'm very pleased with the resolution provided by Harper and the quality of the Waterdrop filtration system.

Clean water and taste good. Easy to set up. We don't know how it does on bacteria. We didn't test that because we have public water, but it filters out the chlorine well.

I acquired the Waterdrop water filter based on my prior exposure to informative content regarding cutting-edge filtration technologies and future inventions. The source of this information was a video highlighting advancements in filtering processes, and the featured company, hailing from Hong Kong, was named Waterdrop. Subsequently, I seized the opportunity to install and evaluate this filter in my kitchen. The installation process proved to be remarkably straightforward, and the filter demonstrated an impressive build quality characterized by both sturdiness and style. Upon sampling the first sip of water filtered by this device, I was profoundly impressed. The taste bore a resemblance to the freshness of cold water sourced from a glacier creek. Specifically, it brought to mind the experience of drinking water from little Pebble Creek on the way to Camp Muir, situated on Mount Rainier. Motivated by my initial positive encounter, I conducted an acidity test on the filtered water. The results were notable, as the pH level shifted from the initial 8.22pH of the regular, non-filtered water to a significantly elevated 9.96pH in the filtered water. This shift indicated a positive alteration in the water's acidity levels. In conclusion, I am optimistic about the Waterdrop alkaline filter's performance and look forward to assessing its longevity over time.

Filter does work! I just ordered this, installed it. Was sure to let is run for 15min before drinking from it. Tasted no different from the tapestry water. Got me a device to test the water. First tested my water from my local water shop, was great ideal drinking water. Then tested water from this filter and the tap water. They were under 385-395ppm. As you can see not much difference. I let it run again in case I didnt let it run long enough the first time. After 30min. It went down to 345ppm. Still far from being under 50ppm which would be ideal drinking water. I will be returning this.

Water taste great. I love the easy installation pocess too. However, a year later, it is impossible to open the cartridge to replace the filter. My husband tried it but he couldn't open it either. Frustrating...

Ease of use

Such a solid water filter system!

I am not sure what to rate this but after boiling this water it test different and it left some white particles on corner
