Enjoy Clean, Great-Tasting Water with the Aquasana 3-Stage Under Sink Water Filter System

Yolanda Jo: The water in the video is from the same cold water connection! We've had this about 6 months with the original filters.
We have a lot of construction around us and our water sometimes has a lot of sediment. We can't have a fridge water filter so this was our next best option. We had a water filter pitcher but the cost of changing the filter monthly due to the high amount of sediment was not cost effective. This under sink filter was very easy to install. You just have to make sure it's super tight around the spigot and caulk around the base of the spigot or the connection will become loose as you move it around. My skeptical husband said, "beautiful wife, you were right again!"

KiwiTheFlightlessKiwiTheFlightless: Got this to replace the Pur on tap filter and it works great. Now I can use any kitchen faucet and still have filtered water.
Beware for overseas users though, the fittings are for US plumbing and I had to make multiple runs to the hardware store to get this installed properly.

Update - May 2023: The Claryum A canister (red) was leaking quite badly… Aquasana Support was prompt to send a replacement but that was leaking also, albeit slower… Support then suggested to swap the cap with another canister and it worked! So far…

So gonna knock down a star. Those who have leaking canisters can try to swap the caps and see if it works.

Attaway-RoundsAttaway-Rounds: We have had this water filter since 2013 (now its 2021) and love it. The water tastes great and the filter removes lead which is not common without going all out reverse osmosis. I don't like RO for filtered water though because of all the water waste, the number of filters to replace, the expense, and having to re-add minerals after filtration.

My only complaint is that the water flow is much less than advertised due to the low water volume (aka pressure) here in Chicago. However, just this week I deiced to hook this filter up to our refrigerator's ice maker and water dispenser. I also added a pressurized water tank to increase the flow rate. Now water comes out like a guizer and blasts glasses full!

I bought this high quality kit (tubing and fittings) which included all the hardware required:

This "iSpring Check Valve":

The check valve is not essential but will prevent any water from flowing backwards through the water filter under...

Christopher Kurka: The filter works wonderfully. We are very happy with it. The unit installed quickly and easily. The water tastes great and the valve turns off with no drips. A huge improvement over our old PUR unit which attached to to the faucet.

However, the dispensing unit seems to be just a bit flimsy. The part that attaches to the sink base feels loose and not solid. I think it could be easily damaged or broke if care is not taken. That said, I don't think this would be a great choice for folks with children. Because I know the limitations of the dispenser, I'm careful when working near it. It's definitely not a deal-breaker with me, but it could be for some.

That is the only reason for the 4 stars.

K K L: We are 2 80 year olds. Easy to install under the counter. Does not take up a lot of room. The water is Clear and tastes really good basically there is NO taste at all. We recommend this system.

Mayank: Pros: easy to install, water quality is fine to drink. Before Aquasana I was using Brita over the counter filter and I was getting 160-170 TDS. With Aquasana I am getting almost similar TDS (around 160-170) which is still good. But keep in mind that this filter is not built only to reduce TDS. This filter does what it is designed for. My Tap water was little heavier (230-250 TDS). Probably, just a carbon filter would have been sufficient. But Aquasana 5300.56 is a good affordable filter and two additional filters along with carbon filter won’t do any harm. I, therefore, decided to get this filter. I have read reviews that connections leak after couple of years. I will have to wait and see (I will update if it leaks). So far it is good.

Cons: nothing much. Flow rate is a bit low but this is not a kitchen faucet. I found the flow ok for a drinking water faucet. Only challenge for me was to drill a hole in my steel sink and tightening the faucet nut under the sink because it was hard to reach. For drilling I used step drill bit and it was quick. For tightening the nut, I tried basin wrench and needle plier. The plier worked in my case.

Amazon Customer: Bueno y fácil de instalar, pero el agua sigue siendo muy dura. La dureza del agua y la falta de un filtro qué reduzca la dureza del agua se nota al hervir agua o hacer hielos.

Clemont: Super equipo AQ-5300 (filtros cortos), facil de instalar, funcionamiento muy bien,
pero.... Amazon MX vende el equipo, pero no los filtros, solamente venden los filtros largos para AQ-5300 +.
Los filtros cortos solamente ofrecen en Amazon USA, pero no mandan a Mexico,
muy mal, muy mal
No compran!!!

Mellow SparkyMellow Sparky: Update - I've revised my review to one star. This water filter system failed catastrophically and flooded our entire kitchen overnight. It completely destroyed the hardwood floor and cabinets. I would not recommend purchasing one of these. And if you do own one, make sure you check it weekly and turn off your water when you are not at home.

Love this filtered water faucet - I found installation to be simple and straight forward. The instructions that come with the kit are easy to understand and follow. The length of hose provided (3' supply line and 3' filtered line) was plenty for my installation - and I'd imagine it will work well for most configurations. A few tips for when you install:
- you don't need a very large hole for the faucet and the cover plate "barely" covers existing pre-drilled holes. If you are going to drill a hole in your counter for this unit, you can drill smaller than the standard.
- I recommend having the handle off to the side (as opposed to facing the sink) - keeps you from getting your hand wet every time you turn it on.

In terms of performance - the water comes out very smoothly - no sputters or pauses. Water tastes great - basically...

Amazon Customer: We just love this filter system. We purchased it to replace a failed reverse osmosis tank that we had for years. At the recommendation of our plumber we chose to go with a filter, this one has three stages, over the RO since it's cost effective and saves water (no waste!) first, Much like the others mention, the water tasted slightly sweet at first. Over time that went away and now I wonder why I ever had a reverse osmosis tank at all. What a waste of money! We love the water taste and that we never, ever run out of water - we fill dozens of water bottles and tanks for use outside or on the road and we never have to wait for the "tank" to fill so we can then use the water. It just flows and flows and we fill and fill! Love it! I like the extra space under the counter, too. It does fill slightly slower, but it isn't such a difference that we care. Further, with all the issues and cost of maintaining the RO, this is a minute concern on our end. I recommend you purchase this filter. I was not paid for this stellar review, either, I didn't receive anything for free. I sincerely mean this. You can message me with questions. It installed in minutes. Super easy!
