The water comes out fast and strong. It makes me wonder if it's even filtering anything out! It tastes great. I love how the spout is set up so it comes up and over the pile of dishes in the sink lol. (I have a tiny sink, stop judging). I do think it's about time to replace the seals though. I do have a bit of leakage that won't turn off all the way, but it stops after the sink is off and you give it a minute for gravity to do the work. It lasted almost a year before it started wearing out. I need to ask the company for replacement parts and I'm sure it will be back to just like new. I like this one better than the previous one I had that was somewhat similar but kind of a dinosaur. I don't know if the water is actually alkaline. I'm guessing that has something to do with it adding minerals back into the water ? That's not why I bought it though so it doesn't matter to me. I know I'm all over the place on this, but I'm here to recommend it. It's a really good buy. Good price and I love the bundles. Should have got me one with the extra filter. BTW, I like that it says to replace the filter when the pressure is getting low (instead of replace it once a year or whatnot) because my family is so weird about it if I keep the same filter in for longer than a year! I don't care, the filter is for me and if they don't want to use it, it's their loss. Don't drink tap water. Review: Fantastic unit at a great price! - I love love love my WD CTF-01!! It replaced a discontinued Aquasana sink faucet model and, I must say, is even more compact, prettier, and with better water flow. Setup was a snap -- and the water tastes great. In use since April, the unit's water stream remains strong; no filter change in view. Speaking of which, I called Customer Service in a panic when I couldn't locate the wrench needed to open the unit when the time came. They sent a new one immediately, no cost. This is a terrific company. Customers' ***** reviews are merited. Happy to have found Waterdrop. ## Features - ๐ˆ๐ฆ๐ฉ๐จ๐ซ๐ญ๐š๐ง๐ญ ๐๐จ๐ญ๐ž: Does not reduce TDS.

I had no idea when I posted the review to give potential buyers a heads up that the company would even look at the review much less respond with such a generous offer. They replaced the filter system at no cost and tossed in a free filter cartridge as well. The new filter system arrived and I noticed that the design is a bit different. Now there is a port on the bottom of the unit where a wrench type device can be inserted to give extra stability and leverage when it comes time to remove the filter cover to replace the cartridge. The tool to do this was also included with the cover wrench and all of the other accessories needed for easy installation. I have not tried to open the filter cover yet as it is a brand new unit, but I feel hopeful that in a year when the filter needs a cartridge replacement I will be able to open it. If not, I feel equally confident that I can contact the company and I will receive prompt help. I'm very impressed with and grateful to the company for the quick and generous resolution to my problem. This is the best countertop water filter I've ever owned. It does what it says it will do. The water tastes great and the unit itself is attractive, unobtrusive, and takes up very little space. My only problem, and it is a huge problem, is that I cannot open the filter when it's time to replace the filter cartridge. Yes, they provide a little wrench but it is absolutely impossible for anyone with no hand strength, with arthritis, or who is just weak in general and without anyone strong in the house to help out to change the filter. I found this out much too late after I'd already fallen in love with the things so today I had to order a brand new unit. I have no one I can ask for help. I read the instructions and I even found YouTube videos detailing how to open the unit but it's impossible. Fortunately, their priced low enough that the cost of buying a new filter is much less than what I was spending for drinking water yearly. They're really could have been a better way for them to have designed this unit for easier opening. ## Frequently Bought Together - Waterdrop Countertop Water Filter, 4000 Gallons Water Filter for Sink Faucet and Filter Life Reminder, Reduces Heavy Metals, Bad Odor, and 99% Chlorine (1 Filter Included) WD-CTF-05 - AquaBliss High Output Revitalizing Shower Filter - Reduces Dry Itchy Skin, Dandruff, Eczema, and Dramatically Improves The Condition of Your Skin, Hair and Nails - Chrome (SF100) --- ## Why Shop on Desertcart? - ๐Ÿ›’ **Trusted by 1.3+ Million Shoppers** โ€” Serving international shoppers since 2016 - ๐ŸŒ **Shop Globally** โ€” Access 737+ million products across 21 categories - ๐Ÿ’ฐ **No Hidden Fees** โ€” All customs, duties, and taxes included in the price - ๐Ÿ”„ **15-Day Free Returns** โ€” Hassle-free returns (30 days for PRO members) - ๐Ÿ”’ **Secure Payments** โ€” Trusted payment options with buyer protection - โญ **TrustPilot Rated 4.5/5** โ€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/639501955-waterdrop-ctf-05-water-filter-for-sink-faucet-countertop-water](https://www.desertcart.us/products/639501955-waterdrop-ctf-05-water-filter-for-sink-faucet-countertop-water) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-22*
