My husband was skeptical to replace our Brita with this system, but now that we have it he loves it. I'm very happy with our purchase because I am an expecting mother and I feel very confident with the quality of the water that I'm drinking.

We use it for everything, drinking, cooking, ice maker, humidifier. Works great once installed. Problem installing faucet as have thick granite counter tops with undermount composite sink. Stem was not long enough to go thru counter top and thickness of sink deck. Found all these style of facets have the same length stem. Solved problem by using ceiling fan mount underneath sink deck. 5 weeks of use and it is still holding strong. We have a Pump hooked to our refrigerator ice maker, pour filtered water into a 5 gallon reusable water jug. We are totally off tap and no more bottle water deliveries or lugging water from the store. The finish on the Nickel Finish faucet has imperfections on the handle, went ahead and installed it and did not report to the company but should have. We got the Water for Life plan and may can get it replaced but was so hard for us to install it, did not want to bother with it now, my inlaws are hard to buy for and thinking this would be a great gift along with the Water For Life as they bought from a home improvement store that later discontinued the filters they need.

Not worth an upgrade

I got this unit last April as a free upgrade that was offered by Aquasana for my old AQ-4601. I had another filter in reserve for that unit so I just got around to installing the AQ-5200. I encountered the following during installation:

1) The instructions said to drill two holes for screw anchors in order to mount the filter on the under cabinet wall, but did not say what size drill bit to use. For anyone who is interested, I ended up using a 3/16" bit.

2) The instructions said to use the enclosed template to drill mounting holes, but there was no template included. For anyone who is interested, I measured the distance between the mounting hole centers and it is 65mm

3) I found that in order to mount the filter to the cabinet wall, the filter cartridges must first be removed. The instructions did not say this, nor did they explain how to remove the cartridges. I found out how online: 1/4 turn, then pull down.

4) Because the space under my sink is very limited I had to install the water lines before mounting the unit, contrary to the instructions.

5) Because the screw anchors are not flush with the cabinet wall, the top of the unit is held off from the wall by probably less than 1/8 inch. However, this small distance caused the bottom of the filters to tilt just a bit from vertical toward the wall. Consequently, when I initially turned on the water the flow was very slow. Once I pulled the unit back to vertical for a moment, the flow increased and stayed that way since I released it.

6) In order see how to re-install the filters, I had to lay on my back with my head under the sink. Again, perhaps this would not have been necessary with adequate instructions.

The main reason that I got the upgrade is that Aquasana stated "The AQ-5200 features a 25% increase in flow rate to 0.5 gallons per minute". That simply is not the case for our unit. If anything, the flow is slower than it was for the AQ-4601 and that unit was fairly slow to begin with.

The unit does filter well and the water tastes excellent. However, before I can recommend this unit Aquasana needs to improve the AQ-5200 flow rate to that advertised, improve the mounting mechanism so that that the unit does not tilt back toward the wall, and improve their installation instructions.

Prospective customers should also be aware that after the water is turned off, our AQ-5200 continues to dribble for 12 or 13 seconds before the flow stops. This is minor annoyance to us, but may bother others more.

does not filter hard water sediment

  • Improving Taste

Comments about Aquasana 2-Stage Under Counter Water Filter - Brushed Nickel:

I love having filtered water on tap. I am disappointed that it does not filter the hard water (lime/scale/calcium) sediment. I have extremely hard water and calcium build up in all of my plumbing including this drinking water filter system. I don't like to think about how much I am ingesting every day. Really like the automatic shipment of filters. My water starts tasting bad before the six months though.

          Comments about Aquasana 2-Stage Under Counter Water Filter - Brushed Nickel:

          Easy to install the filters and the water lines, but hard and akward to install the faucet. Difficult to tighten the nut beneath the water faucet because typically a very small space not visible from beneath the sink. Aquasana can make this much easier by providing a tube-like wrench with cutout at the top that fits the standard size nut. Not possible to fit pliers or a wrench into the tiny space at the back of your sink. I finally found a way to get the nut to grip against a recessed hole in my countertop and then I tighten the faucet from above by turning the faucet itself. This took many failed attempts, where a simple plastic tube-wrench would take 1 minute. Otherwise, very easy to install, water tastes very good, flow is adequate for drinking or cooking or washing veggies. Much cheaper and more convenient than large water bottles.

              Comments about Aquasana 2-Stage Under Counter Water Filter - Brushed Nickel:

              I have been using mine under the kitchen sink for over 2 years. Yes, it is a bit slow, but well worth it. When I am at a neighbors and drink their water, it generally is just a sip till I get back to my place.
              I did have problems with the handle on the original one I bought. When I saw they changed the type of handle they were using, I decided to buy the newer model. Their customer service sold me the new one at a really reduced price.
              My only complaint is trying to replace the filters. As I am older, I cannot get under the sink too well. But seems to be no problem for my son to do it.
              I recommend this to anyone that has bad water or is concerned about all the chemicals found in our drinking water.
