17UA Undersink Filtration System

I just received my order for the waterdrop under sink filter (model WD-17UA-UF)! It’s only been installed for a couple hours but so far I’m very impressed with the filter system and I’m satisfied with my choice! The package came with everything needed for a quick and simple installation. Literally as simple as deciding where to place the filter, using the template sticker to put in the two included mounting screws, pushing the included water hoses into the filter head, then mounting filter head onto the two screws! From there I simply turned off cold water supply, unscrewed the faucet hose from supply pipe, screwed inlet hose onto cold supply pipe, then attached the filter outlet hose right to the faucet hose that I had initially unscrewed from the cold water supply pipe. VERY SIMPLE INSTALLATION! It took me 15 minutes to get it installed in total, plus 5 minutes to flush out the filter and check for leaks. I didn’t need to use any of the adapter fittings since my connections were already 3/8” but it was great they were included just in case! I also didn’t use the included teflon tape. BOTTOM LINE: If you’re looking for a high quality easy to install water filter that fits under most sinks and doesn’t produce any additional waste water then this one should be at the top of your list! The water tastes great and the sleek design makes it unobtrusive in the back of the cabinet. Installation was very simple and painless! NOTE: Be sure to measure and leave enough space below the filter cartridge in between the bottom of cabinet before you install the mounting screws! Just a few inches is all you need so that it’s easy to remove and replace new filter cartridges in the future! Also when deciding where exactly you want to mount the unit be sure to take into account where the hoses run so that they aren’t in the way. **Plus if you have the type of faucet with a spray head that can be pulled out to extend when spraying dishes then make sure that the filter inlet and outlet hoses don’t obstruct the sprayer hose OR THE RUBBER WEIGHT that’s attached to it underneath the sink!** But if it does get caught up you can always loosen the rubber weight and adjust its positioning under the sink! !!All in all great filter, great system, and great clear simple installation!! (I’ll update this in a few months if I happen to have any future issues, but I don’t think that’ll be a problem.)

I’ve bought two of these now, one for under the sink and one for an ice maker. Super easy installation, not one leak, and the water tastes great!

This filter was exactly what I needed - non-intrusive and inline to use under my kitchen sink. The taste of my water immediately improved. The package included everything you needed with extremely helpful guides and instructions. Customer service was also super responsive and helpful if you're worried about the fit. I hope this lasts a long time and I don't have to update my review later!

Takes the chlorine taste out of tap water. Fills a gallon in a minute or 2. Stopped buying plastic bottles as taste is comparable. Good quality. Easy to install

Installation was easy and the filter has removed the tap water taste from my water. So far I'm very impressed!

Works perfectly out of the box.You can taste the difference immediately.I highly recommend this filter system to everyone.Great product.

Hoping it lasts as advertised, but set up was easy and fits well. Be sure to double check on the size, it’s much bigger than I initially thought.

Easy install and works well. Tap water is now drinkable.

Purchased the 17UA in late October 2025. Have had different water filters in the past including Kangen water filters. Easy to install with all hoses provided which really makes it simple. Although we didnt test the water for the level of contaminants, the water is clear, odorless, and great. Fast forward to late February 2026 and the water had an odor yet was still clear. Contacted Waterdrop and communicated with Becky in customer service. She immediately addressed our concern and promptly sent us a replacement filter within 2 days. Now all is well and the water is again perfect. Highly recommended waterdrop not just for the quality but also the customer support. Becky is extremely thorough, kind, and helpful so you have no worries as she takes care of any issues you may have. Thanks Waterdrop

The most boring liquid i have ever tasted. Tasteless and odourless. Install was easy since I already had a hole in the counter for a soap dispenser that we don't use(the difference in hole difference vs tube difference is specifically a me problem and not a product problem). The hole needed for the threaded tube is probably 3/8"(9.5mm). The space needed under the sink where the filter is needed is about 21". Having on demand filtered water saves me counter space and gives me the option of cooking with filtered water too. The flow rate is great. Definite advantages over a gravity filtered, counter top, jug type filter system.

On goûte la différence, facile à installer. Très satisfaite

Took me about 30min to install, but mostly because of my incompetence - a plumber would need 5 minutes. It’s incredibly convenient to have this tap and be able to fill filtered water immediately.

Mon eau avait une odeur de chlore et depuis l’installation de ce système pour filtrer l’eau fini les odeurs Je le recommande fortement
