Water tastes like nothing, which is what I wanted
Ok, so I read the reviews on this before going with it, but it fit the bill for what I wanted: An inline filter for the cold on my faucet. If you are considering this you want this unit because 1> You either can’t or don’t want to put in a separate filter faucet 2> Are tired of standing at your fridge for filtered water 3> Don’t need whole house filtration. This is a 4 month review and I just replaced my first filter. First things, install, if you have basic plumbing skills you can easily install this. Simple, didn’t need to get anything other than a couple of wrenches. Second, water quality: Perfect. Tastes of nothing. Third, water flow: It’s slightly lower than the hot side, but I’m talking slightly. At 4 months it was still fine. Fourth filter life: It went at about 3.5 months where I could start noticing a taste, that was a litlte disappointing. Until I really started thinking about our water usage in the sink, and yeah we cook and clean daily and probably use, no joke, 2 gallons a day in straight drinking water. Which doesn’t include the rinse and run that you do for temp and things so easily double that. Putting this on a cold water line for a kitchen sink is going to run it off quick. Wife and I did a blind taste test on the filter (science!) change and we both agreed (in secret recorded answers) that the filter had gone past life. Honestly, consider the coffee, iced tea, water, cooking, etc, everything that we do this is a bargain .. and no more standing at the fridge waiting forever to fill things up.

Easy to install and works great
I got this product to replace my reverse osmosis system I bought from this company 10 years ago. I needed something that would retain the minerals but still give me the same filtration that I expect from a high quality system. This was easy to install ,less than half hour. I didn’t notice any difference in the performance or flow of water after attaching it to my sink. I bought the used version and it was a great value for my money I bought a second one.

One year review
Installed this system one year ago, still on the original filter and still tastes great. Have only recently noticed a very slight slowing, but still, the cold side water pressure is better than most houses without a filter. Happy with it so far

Good flavor, removed sediment, easy to install, good flow rate.
We have a small sink in our wet bar that we previously used primarily for making coffee and cleaning coffee related tools. I started to notice that sediment was floating around in the carafe when I was making coffee. Our filtered water dispenser in our refrigerator is also loud and slow (which is a disappointment since it is a GE Monogram built-in product). Finally, it dawned on us to get an under-sink filter and use the wet bar to quickly fill glasses of water or water bottles with clean water as well as to have filtered water for coffee. This filter immediately removed the sediment from the water, which is great Although I am sure the sediment was harmless, but its nice to see perfectly clear water. Flavor of the water is also very good and clean. Indistinguishable from bottled IMO. Flow rate appears undisturbed by installation of the filer, which was very easy if you have BASIC plumbing skills and can use a wrench. I connected the filter to the cold side under the sink, and then use the hot side to rinse and clean to avoid running the filter needlessly, thus preserving its life before needing to replace.Wish we had got this sooner!

Great unit but donât buy from Amazon
The unit works perfectly. The filters are bit. Easy to install. Not leaks. The only complaint is I needed this unit right away because we couldnât turn water on with this hooked up. I ordered from Amazon for quick delivery. It was supposed to be delivered on Saturday. The facility is only 45 minutes from where we live. I call c/s. And they assured me that it would be delivered Sunday. But I could see from tracking that it didnât leave the facility all day. So I called in and she said it would definitely Be delivered by 10 pm. And the website wasnât updated. It never came Sunday. It was delivered late this morning. I should have went to Jome Depot or Loweâs it would have been quicker.

works well with easy quick replacement
We have used this filter type for several years with total satisfaction. It is located in our basement under the kitchen with feeds to the refrigerator ice maker and a dedicated filtered water small faucet. Changing the filter takes only a minute or so. Good tasting water and usually lasts about a year (2 people). Highly recommended!

Scope of the ENTIRE installation prior to beginning
This took about 45 minutes to an hour to install. There are somethings you can look at and get a general idea of how to install them – this really isnât one of them, but the instructions were good enough to fill in the gaps. You will do yourself a big favor if you scope out the entire installation job before beginning – it will likely save you a little time. If you have 3/8â fittings on your feed and faucet fixture, you likely wonât need the 2nd hose that is included – simply connect the hose you disconnected from the feed (hose the carries water to the faucet) to the output of the filter housing. The should have been made clearer in the instructions. Attaching the filter housing to the mounting bracket (four screws in the top of the unit) is – from my experience, strongly recommended, particularly if you are planning to mount the filter in a cabinet under your kitchen sink like I did.There has been no discernible reduction in water pressure. The APEC brand RO water filtration system comes highly recommended, so I went with their under sink filter. It has only been 2 days, but so far so good. Installation was relatively easy, but could have been a little easier with better instructions – or perhaps a YouTube unboxing video. Minor complaints in the grand scheme of things.

Product was exactly as described and fitted perfectly.

Great product but if you are looking to reduce TDS this product doesn’t
Amazon Customer –
They fit pneumatic lines instead of hydraulics. Maybe guess that’s American standard. Amazon sold this on Amazon SG. So be very careful.Having a tough time looking for adapters and fittings

Says in the description that it filers out heavy metals. When tested with my TDS reader, the reading was as high as the plain tap water. Filtering out dissolved solids was very important for me. Contacted the manufacturer and was told it only filtered chemicals such as chlorine and fluoride. Ended up returning it.
