We have a single handle kitchen faucet and wanted to filter hot water as well as cold so I bought 2 uc-200s. Cold install went perfectly, but the side sprayer somehow vapor locked the hot until I used the sprayer. Unfortunately for me I didn't think to try using the sprayer until I had swapped hot and cold filters, fighting shutoff valve

The UC-200 filter does not keep calcium out of our faucet. This is disappointing.

UPDATE:
Upon reviewing my comment above, the company quickly contacted me by phone. Working with the Customer Support agent, Chris, I was able to determine that the major reason for the calcium deposits was caused by the instant-on hot water

The APEC Top Tier 5-Stage Reverse Osmosis system delivers on it's most important function - clean, good tasting water, and it does it at great value. This is a six month review. This 5-stage system includes 1 pre-filter, 2 particulate filters, and 2 micro filters. This gives it large capacity for cleaning silty water, while providing a

"You have one on every floor?" Yes. I have three APEC RO filters, and I love them all. Let me explain:

Where I live, we have "city water", but that's really a community well. The water here is EXTREMELY hard. The last time I had it tested to size out a water softener, I was hovering around 30 grains per gallon (that's about thre

This is an absolute must-have during our unfortunate period of being forced to stay home (forced in a sense, but you know what I mean). Given, our install was within the breakroom at the office here, but some of us will be buying into these for our homes as well as it keeps us from having to worry about finding water in stores with so many

I learned about reverse osmosis water from a girlfriend who later dumped me. She’s gone, but I still have the RO water. I win.

Although I knocked some stars off for the installation being complicated, that’s really not fair because I didn’t install it. I had a plumber put it in. But I saw enough to know that there is no wa

I am a 60+ year old female, with an arthritic right hand in a 1931 bungalow home. Anyone who owns an old home knows there will always be the unexpected lurking when working on the house - so I went into this project anticipating a few hiccups.

So far so good but I tested the PH in the filtered water and it showed 5!!! Not what I was expecting. I ordered this system because it supossedly adds minerals back into the water. Has anyone else have the same issue and how was it resolved? thank you.

But I'm pretty critical, so I'll update this review if I find any more gripes. I guess I should include I almost wet my pants when I heard a loud snap when installing the RO membrane cartridge in i

It all went together exactly like the installation directions, which were clear and easy to understand. My wife is a picky water drinker and her choice of water is Nestle's pure life.

My wife just finished installing the RCC7AK under our kitchen sink, and it took a little over an hour taking her time and watching the 15 minute youtube video while going step by step.

I'm rating this 5 stars because the unit is as good as you could get for the money. Granted, for more money you could have more expensive fittings, etc, but they are really not necessary unless you are going to be constantly moving and reassembling.

This is a best quality system. I order 2 system from them in one moth. One of them has problem with the tank, the support team call me 2 hours after I was send the email, and the replace tank came three days after. Excellent tech support, and good price. Extra filters will save for another year. Fast delivery, Very easy installation.

First of all, a disclaimer. I haven’t had this system running, so I can’t speak of how well it performs. But due to what I read in the manual when I received it, I decided not to install this system and returned it. The maintenance sounds quite involved and time-consuming.

A lot of good descriptive reviews here, I'll add mine here but will focus on my perspective as someone living in Israel.

We have a well in our new house that has elevated arsenic (0.020) and radon (15,700). The radon is really high, the arsenic is twice the acceptable limit.

Short reviews are my favourite, if a product is good you don't have to write a novel about its problems. This is one of those reviews. This product is perfect, thats it.

We bought this system back in 2013, after a Kenmore system we had for only a few years became too expensive to use anymore. We paid way more for the Kenmore system, so I thought this one was too good to be true. But, we tried it out. It has been AMAZING!

After watching a youtube video and scanning the instructions, I tackled the under-sink install. By far the hardest was the fastening of the faucet in the back of the sink - hard to reach and no tool will easily grab the nut that needs to be tightened to ensure a solid faucet on my old flimsy stainless steel sink. Once that was tight, I rea

New Review:

Correcting my previous review, because originally, I rated the product two stars. It was my mistake not to realize that after the previous filter ruptured, the ppm on the new one was 0.16, instead of 0.7, the latter being the usual reading. Please, notice that I monitor the ppm at least once a week.

I should start out saying that I am very picky about my water. I purchased a home a few years ago and had been using a Brita filter just to get by. It was OK. Much better than tap.

We love this filter system because it was easy to install, it's invisible under the sink, and it filters the chlorine taste out of our water. We've bought new filters for it many times in the three years that we've had it. The one disappointing thing about it is that the flow rate falls off pretty quickly with time. We're in San Francisco,

My reverse osmosis system was barley trickling out water so I started searching for a replacement. The first positive that caught my eye was the one piece filter. No unscrewing the container, taking out the old filter, cleaning the container, putting the new filter in, and then screwing it back on. With Home master you plug it in and done.

The unit is quite stylish, perhaps too stylish to be hidden under the sink. The compact nature of the unit makes for reducing space needed to install. Mostly uses vertical space, the horizontal footprint is quite small for what it does.

This has been a no-problem filter. Once you get the system installed, it's a piece of cake to do filter changes. Just remember to turn off the water first!

I have previously installed an RO system that utilized the common tank/bladder reservoir and 3 cartridges under our kitchen sink.
