Review: Fairly easy to install, tastes good - The kit came with zero instructions, these are not hard to find online. Some of the parts looked a little dirty, as if this may be a refurbished unit. I'm taking 1 star off for those items. Otherwise it was fairly easy to install, tastes good, and has decent flow rate. I was worried about leaks seeing reviews of what happens when folks go to exchange the filters. Luckily no leaks upon install. We probably use an average of a gallon a day, so hoping these filters last a while. I originally wanted a whole-home filter, but after doing the research and seeing how much replacement filters/parts are and the intervals to exchange them, we couldn't afford the ongoing costs. These filters seem to be pretty reasonable in price, and a good compromise over a whole-home system. I did have to buy a 1.25" diamond blade hole saw and auger to create the additional hole required through our granite countertop. This was also fairly straight forward, but a lot of cost for the tools for a 1-time job and it was very nerve racking lining up the hole as near-perfect as I could get it and trying to keep the bit from skipping around when first starting it. I probably saved a hundred dollars or more vs hiring a pro to come drill it. The faucet is nice, but a lighter colored oil rubbed bronze than most plumbing parts. It does sit a little less than plumb, and I wished there were instructions on how to take the little handle off so you can adjust where the on/off starts. As others have said, the water tube attaches to the bottom and could easily be pulled out, so be careful messing around under your sink after it's hooked up. It makes no noise when turning on/using, I do hear a tiny clunk when I turn it off. The tubes that go into the base unit have to be pushed all the way in. I thought I had the larger one in and decided to double check it and I pushed pretty hard and twisted a little and it went in about another inch. I'm glad I checked it. The smaller outgoing tube was easier to push in. I think a lot of people might be having issues with leakage not having these tubes pushed in all the way, especially the larger intake tube. Leave a little extra tubing when you install, so you can take the base unit off the wall if needed to change the reminder button-cell battery without worrying about a tube coming off. I have not done any water tests, I trust the tests others have done and posted in their reviews. I know this doesn't remove fluoride and a few other things, but it's got to be better than a ceramic berky-like filter. Aquasana should include instructions, and a shut off valve just for the tube going into the filter (so you can keep the cold water active and turn off the filter for maintenance). **Update Feb 2024-water flow completely stopped after 6 months. Emailed customer support, no response. I took a chance and ordered a replacement filter set direct from manufacturer. Kit arrived in a week and I replaced all 3 filters. Two filters were pretty dark colored. Kit also came with a new battery. Turns out the original kit had the battery installed backwards, so it never beeped when it was time to replace. New filter change, new battery installed the correct way, and I get a few beeps and turn back on the water. Checking for leaks for a couple weeks. All is good, water pressure is back to normal. I hear about the cartridges leaking after opening and changing the filters, O-ring problems, etc. I was very slow and deliberate taking everything apart and putting it back together to make sure I never cross threaded anything or damage the o-rings. When you insert the filter, there is a little play/movement possible while you try to screw the housing in around it. Hold it upside down so gravity helps keep the filter tight to the lid while you screw the cover back on. And by the way, it's been 3 months since I emailed customer support, no response besides the obligatory "thank you for emailing support, someone will be with you...", no follow up emails from support. **Update Jan 2026-Unit has been working great, no leaks. Haven't had any issues since 2024. I've changed the filters about every 6 months or whenever it starts beeping. If you set up auto-shipment direct from the manufacturer for filters, note that they charge your credit card, then ship the filters about 2 weeks later and it takes about a week to get to you.
Review: Beware - bad product / even worse customer service - I bought this Aquasana water filter system for my kitchen sink. For some reason, I was sent (and charged for) 3 units. Obviously, I contacted desertcart and made arrangements to return two units for refund. In the meantime, I hired a plumber to install the unit. The plumber is a licensed, insured and an experienced plumber. He had the worst time installing the filters. Installing the unit was very basic - no problem there. However when he put in the filters they leaked. Because I had two extra units. He tried those filter (I was willing to take the hit). After trying 5 different filters (on a 3 filter unit) he was finally able to get it to stop leaking. Fast forward 7 months…I knew I had to change the filters every 6 months. As luck would have it, I had a plumber out to fix an unrelated issue and I asked ‘can you change these filters for me as long as your here’. This was not the same plumber as did the install. I had purchased new filters last month and had them ready for install. This plumber also had the same issue as the first plumber…the new filters leaked. He couldn’t tell what the issue really was, because once the filters are in the housing, you can’t see them. He said they went in easy, and shouldn’t be leaking. Finally out of frustration, I said just disconnect it and I’d contact Aquasana since it’s still under warranty. After speaking with Julie at Aquasana tech support, I was told that she could not refund my money, only send replacement parts…which is impossible since I (nor the plumber) can tell what’s leaking. I was asked to take a video of the leak and email it to them??? What? I told them no, that’s ridiculous. I’d have to call the plumber back out to hook it up again, to take a video of dripping water? Riiiight! Julie at Aquasana said I needed to contact desertcart, since that’s where I bought the unit. I told her it was at the Aquasana Store on desertcart. She said she has no authority for returns, even under warranty and to go thru desertcart. The funny thing is, desertcart doesn’t give me an option to return this unit…it does refer me to the toll free number to Aquasana (the same number where I spoke with Julie). Basically the round around. So I’m now out my money. I don’t have a water filter and I still get to hire a plumber to remove the unit (he did disconnect it from the water, but it’s still under my sink, and the small faucet for the filter has to be removed and I need to put in a soap dispenser or something to fill that hole in the counter top. Thanks Aquasana for standing by your product, which has been problematic from the start, thanks for helping us out when finances are tight. By not offering a full refund to a defective product and not giving a second thought to me paying a plumber AGAIN to come out to remove there defective machine. Beware buying from Aquasana. The product I have is defective, still under manufacturer warranty and they will not refund me. That’s just wrong.

## Questions & Answers

**Q: Does it filter Arsenic?**
A: After searching the literature, I do not see that listed.

**Q: How long does the battery last?**
A: The battery in this system acts as a timer, so it should start to alert you at the 6 month mark. Keep in mind that the battery has nothing to do with the filtration process. Its sole function is to activate the Bluetooth component and keep track of the internal flow meter/timer. 

Thank you,
Aquasana

**Q: How does the 5300+ calculate the gallons used in the app? Please be specific.**
A: Thank you for your interest in Aquasana!

The system utilizes a Reed switch flow meter inside the manifold. The information is transmitted via Bluetooth to app.

Thank you,
Aquasana Customer Support

**Q: Does this filter remove glyphosate?**
A: You will have to contact their Customer service, they will have that answer

### ⭐⭐⭐⭐⭐ Love this filter
*by S***H on April 1, 2026*

Our water tasted like chlorine and the Brita pitcher we had been using did not do anything to help with the taste or smell of chlorine. This was easy to install--the hardest part is just working in a tight space under the sink (although you should be comfortable drilling holes). Our water tastes GREAT now. It's completely quiet and seems to be of good quality, although time will tell. I could not be happier with this purchase. I didn't want to/couldnt drill into the sink but put it in the countertop next to the sink and am completely happy with it.
