WaterdropTST-UF 0.01μm Ultra-Filtration Under Sink Water Filter, Stainless Steel Water Filter for Sink, 5X Service Life, 99.99% of Contaminants Larger Than 0.01μm, Direct Connect to Kitchen Faucet

This is a great under-sink filtration system. The water is clear and tastes great. It comes with two quick-connect 3/8 lines that make it easy to connect and disconnect the unit from the supply and faucet. This means you can just shut off the supply valve, disconnect the whole unit, and change the filters from the counter-top, then easily put the system back under the sink and quickly reconnect. Love it! No need to crawl and crouch under the sink the whole time.The finish is high quality stainless steel, and comes with a black steel filter wrench for changing the filters, which is a nice touch. It looks beautiful and feels "quality", not cheap plastic.Connecting from the water supply was easy. I chose to split my supply so the main faucet remains unfiltered, and only the separate drinking-water faucet is filtered. I added a dual-valve compression fitting to replace the existing single valve, which has nothing to do with this unit but necessary for my setup. Pretty simple. The supply side to the filter was easy to connect using one of the supply lines with the female connector. The other provided supply line has a male end, for which I had to buy an adapter to convert the 3/8 male line to a 1/4 female so I could connect to my faucet.Check your faucet connection... if the faucet itself is 3/8 female, you're all set. If not, you'll need to purchase an adapter to take 3/8 male to whatever you have.This filter system is very fast! It is just as quick to fill as the main faucet, even when going through the mini faucet. It's amazing how efficient it is. I mainly use it to fill a coffee carafe each morning, and it is such a pleasure vs the trickle coming from the fridge water filler that I was using before.

Keeping this short and simple. It's a solid construction, beautiful chrome finish, and easy to install. A few reviews mentioned about not actually using the hanger to elevate it in your cabinet space. Based on the weight of it, I'd agree. The hanger points do make for a good stability hold though.Flushed it per the directions, and then enjoyed a clear, clean, odorless glass of water. Our refrigerator already filters water, so this was a good way to compare. Considering the better filtering of the unit, it isn't surprising it tastes better than the fridge-filtered one. Great to have the option for tap temperature water vs cold from the fridge. Looks great, and no more chlorine and chemical smells from water treatment.I haven't reached the point of changing out a filter yet, but hope that will be nice and easy too. Still, installation with just a little plumber's tape/silicon tape and simple tools is all you need.

Super easy, NON-DESTRUCTIVE, undersink installation! ALSO, super easy and convenient filter replacement. Easy to maintain~My apartment has surrounding city area has pretty hard water from the tap and will leave residues on almost everything. This product system and the filters from Waterdrop do a super great job at taking all the microscopic and various atomic scale contaminants out of our water. I know the filters are doing a great job because shoooo, the used filters be coming out pretty gnarly at the 6 month/12 month replacement schedule I use!The water coming out of our faucet tastes, feels, and looks great! Tastes better than regular bottled water from grocery stores.It's so much more convenient not having to either grab water bottle/water jugs from the grocery store or have a water pitcher with a filter in the fridge.

I didn't want an RO system because I feel really uncomfortable about the amount of water wasted. I did some research to better understand what TDS really means and figured I didn't need a reduction for that (standard tap water was 220 which is within normal range). My biggest issue with my tap water was the smell of chlorine. I had been using my fridge water that only has a carbon filter, and haven't died yet, so I figured this filter would be a good upgrade.It was a breeze to install, and I let the water run for 10 minutes as instructed. Didn't notice any decrease in water pressure and the water comes out perfectly clear, with zero chlorine odor and it tastes great. I can fill a jug for the fridge in about 20 seconds, the cats' fountain in 5 seconds... I feel I've gained some priceless hours of personal time back.

Easy to install. Looks great. Cleared up water coming from our well.. Fit nicely under our sink. Price was reasonable, particularly since the filters last a long time.

I've now had this item 6 months and ordered a new p1 filter as indicated. In attempting to install the new filter the lines do not disconnect, nor does the included wrench fit properly to allow for taking it apart. I won't be able to do this by myself going forward. Totally wasted money, well over $200 with the new filters. I would have given 2 stars because I did successfully use the system for 6 months and it was easy to install, however, now that I have contacted Waterdrop customer service, I would prefer to give zero stars. Their best resolution is for me to buy a better wrench, or hire someone to change the filters. I can't imagine going thru this every 6 months.
