Rated 5 out of 5 by from A high quality counter top filter. These replacement filters for our 2 stage counter top Aquasana filter are nothing short of incredible. I spent many days shopping locally and on-line as well as talking to friends and relatives in order to find a counter top filter that would really remove a lot of the substances and chlorine smell that we did not want in our water. I firmly believe that there is nothing else short of a whole house system that will remove as many contaminants at the high percentage that this unit does. Plus it's a snap to install and maintain, especially when using Aquasana's "Water for Life" program. Plus-great customer service when needed.

Rated 5 out of 5 by from Great water and so easy to use! I had a countertop filter for many years, and finally realized that I did not have to live with its cumbersome presence next to my sink, with a hose that tangled up, a diverter valve that endlessly clogged.... I researched and found Aquasana. But I did not just buy, I called the support phone number and spoke with a live person about the product and its capabilities. Then I chose the under-counter unit that was right for my size household. It was easy to install, though I did ask my plumber to come so that the dedicated spigot would be professionally installed at the sink. All is good and we are very satisfied.

Rated 5 out of 5 by from Peace of mind I had my water tested before we bought an Aquasana under the sink filter - the lead level was below the action limit and could be dealt with by running the cold water for a minute before use. I wanted more protection for my family, but can't afford to have my 1957 house entirely re-plumbed. The lead is not coming from my municipal water supply, but from the solder used on the water pipes being dissolved into the water sitting in the pipes. Aquasana filters take the lead out along with all the other harmful compounds. The filters leave calcium and magnesium. Now I don't worry about the water we drink and cook with. Our water would be costly to buy at the store: high magnesium and calcium, pH 8.2.

Rated 5 out of 5 by from Excellent water filtration system! When we bought this 1865 classic home a year ago we found the Aquasana in place. A new box of filters was under the sink and labeled to be replaced the month we moved in. We contacted Aquasana and got set up on a regular delivery system for the replacement filters. We have now changed the filter inserts twice, since the original change and are having absolutely no problem with the system at all. We love the spigot system and the clean, clear water it delivers us every day. It is all we put in our dogs water bowl and travel canteens. We are VERY PLEASED with this system. Thank You!

Rated 5 out of 5 by from Live longer with the water nature wants you to have We lI've our countertop Aquasana. From the first glass we knew we would have clean and healthy water to drink. Not that Fort Worth water is bad, but with most municipal water systems in the US becoming old, the likelihood of contaminates increases as time goes on. One thing we didn't see was an Aquasana system for our fridge. So my husband, being the inventive engineer saw that the below the sink Aquasana faucet system could work with the water connections that fed our Samsung refrigerator. So we ordered it and took less than 20 minutes to hook the system into our refrerator water line. We now have cooled water and clear ice cubes where we used to use ice trays for ice. Love you Aquasana and glad I signed up for the filters for life program.

Rated 5 out of 5 by from Best Filter System We Have Ever Had This is the very best filter system we ever had. There is no after taste, never cloudy, no odor. Always dependably good. Taste is as pure as you you would find in an unadulterated, pristine mountain lake. And I truly mean that. The price for this 2 filter under the sink system is very affordable, too, and by signing up for Water For Life, there are no shipping charges and the new filters are sent out automatically every 6 months. An excellent plan so changing them is not delayed or forgotten. I highly recommend these Aquasana filters.

Rated 5 out of 5 by from Good clean taste I wrote that this is easy to install. After the first time replacing the filters, it was easy. That first time required quite a bit of effort. I am still not sure I got the battery in correctly, but it works and beeps after 6 months to remind me to change it. I did not mount the filters under the sink, but rather placed them in a plastic tub for ease of access. I dislike working under the sink. So, it is not the space-saver for me that it could be. The water tastes great. I can really tell a difference in the filtered and the tap.

Rated 5 out of 5 by from Thanks. Love my filters. But since we are just my husband and I using it we don't change it every 6 months. In fact it was too much later when we got around to it this time. It was March when we changed the filters. So when we received the filters immediately after that time that they were changed we really don't need them until September now. Please change our time to receive the next shipment. We will try to remember to change it more often. I hope you can change our mailing and billing to accommodate us. Thanks for your help.

Rated 5 out of 5 by from Have been a satisfied customer for years I am very happy with the kitchen filter and the shower filter that my family have been using for years. The filters are affordable. We have no problem with the taste (our 4-year old is happy :-). I use the filtered shower water to fill the bath tub for our daughter. We replace the filters every 6 months. I don't notice any difference with the shower filter regarding the flow after 5-6 months. However, the flow from the kitchen faucet slows down after 4-5 months but it's not too bad. It's still worth it.

Rated 4 out of 5 by from Water quality great, but hard to install We bought our house with an Aquasana Filter already installed in the kitchen sink, and at first we weren't sure if we wanted to keep buying filters for it. But, I'm glad we gave it a shot! The water from the tap is perfectly safe to drink, but I just don't like the taste of it and was wasting a lot of plastic buying bottled water instead. These filters make the water taste much better, and I'm sure I'm more hydrated as a result! The only con I have against them is how hard they are to install - to form a tight pressure for pumping the water, I guess, a semi-vacuum is created inside the chamber that really pulls everything very tightly together. It's so hard to twist open and put the new filter in! I definitely can't do it alone and need someone to come help me twice a year to install.

Aquasana FAQs

  1. Do I have to pay for a plumber to install the system?

    Our under counter drinking water filter systems are very easy to install, and it only takes a few minutes to do; no plumber is necessary. If you have any questions or need assistance, our technical support representatives at 866-662-6885 can walk you through the installation process.

  2. How often do I have to replace the cartridges and how much do they cost?

    We recommend replacing the cartridges after six months or the specified gallon capacity to prevent the growth of bacteria in the system. The AQ-5100 Single Stage has a capacity of 200 gallons, the AQ-5200 Two-Stage has a capacity of 500 gallons, the AQ-5300 Three-Stage has a capacity of 600 gallons and the AQ-5300+ Three-Stage has a capacity of 800 gallons. Replacement filters cost $29.99 for the AQ-5100, $59.99 for the AQ-5200, $64.99 for the AQ-5300 or $79.99 for the AQ-5300+, but you can save 15%, get free shipping, and extend your product warranty by signing up for our no-contract auto-ship filter replacement program, Water for Life. The performance indicating device on the AQ-5200, AQ-5300 and AQ-5300+ systems will sound a beeping alarm and flash red when it is time to change your cartridges. The AQ-5300+ also contains Bluetooth connectivity so you can download our iPhone App and get alerts for when it is time to change your cartridges and even order new replacements straight from the App!

  3. Is this purified water?

    No, and actually, purified water is not as healthy as filtered water. Purified water undergoes reverse osmosis or distillation, which strip everything out of your water - not only the contaminants, but also the healthy, natural minerals. Our system uses selective filtration designed to reduce contaminants from the water and leave in the natural healthy minerals like calcium, potassium, and magnesium.

  4. How do I recycle the replacement filters?

    We have designed this system to minimize the environmental impact of our replacement elements, which are over 95% biodegradable carbon. Our company will recycle the filters for you, but we do not cover the shipping cost to return the filters back to us. In reality, the environmental impact of shipping the filters back to us outweighs the good of recycling. To recycle the drinking filters yourself, remove the ends of the filters, recycle the plastic parts (which are appropriately numbered) and put the carbon either in your compost pile or garden (carbon is good for plant life), or just throw it out (since the carbon degrades quickly, and is a positive component in a landfill).

  5. I'm a renter, so I can't drill or modify the plumbing. What should I do?

    To install an under counter system, you can remove the existing sprayer or soap dispenser on your sink and install our faucet in its place. This option will not damage or permanently modify your plumbing. When you move out, you can easily remove the system and reconnect your plumbing back to normal. If you do not have an existing hole in your sink from a sprayer or soap dispenser, we also have a countertop drinking water filter that conveniently screws on to most kitchen faucets.

  6. What is the size of the brass T-fitting for under counter and premium under counter unit?

    The most common size is 3/8" which originally comes with the system purchase. In rare cases some customers may need a 1/2" T-fitting which is sold separately and is available for purchase through technical support.

  7. What size hole do I need in my sink for the under counter and premium under counter systems?

    The faucet that is included with our systems requires a 1/2" hole.

  8. What does TDS mean?

    TDS is the acronym for Total Dissolved Solids, the amount of dissolved minerals and metals present in water. TDS meters tell you the concentration of dissolved minerals and metals, but are not an accurate measurement for contamination. Aquasana products reduce and remove harmful TDS like lead, but selectively retain or replace healthy dissolved solids like calcium, magnesium, and potassium.

  9. What is BPA? And why are people concerned about it?

    BPA stands for Bisphenol-A, a contaminant found in most plastics. BPA can adversely affect your health if consumed at high levels. Aquasana drinking systems do not contain BPA, and our filtration process reduces existing BPA.

  10. Does having hard water mean it is contaminated?

    Hard water is more of a nuisance than a health risk, and is not necessarily contaminated. Most water sources in the USA are considered hard. Hard water is generally safe to drink, after it has been properly treated.

  11. What is soft water, and is it safe to drink?

    Having soft water just means you have a lower concentration of dissolved minerals in the water (primarily calcium and magnesium). Soft water does not mean clean water. Your water can be soft and still contain contaminants.

  12. What is selective filtration, and how do Aquasana systems filter drinking water?

    Selective filtration is the process of sub-micron filtration, micron filtration, adsorption and ion exchange, all of which selectively reduces chemicals, heavy particulates and most dangerous heavy metals from the water while maintaining healthy minerals like calcium, magnesium and potassium.

  13. What is the difference between the single-stage, 2-stage and 3-stage under counter systems?

    All of our drinking water systems use the same Aquasana Claryum® filtration technology. The single-stage system lasts 6 months or 200 gallons before the cartridges need to be replaced. Our 2- Stage system has a higher capacity than the single-stage, giving you 6 months or 500 gallons of clean, filtered water. The 3-Stage system includes a 20 micron pre-filter before the two Aquasana Claryum® filters. This pre-filter increases the capacity of the system from 500 gallons to 600 gallons. In addition, it improves flow rate in high sediment areas. The 3-Stage Max Flow system adds even more capacity to 800 gallons, a 44% increase in flow rate at .72 gallons per minute and Bluetooth connectivity for filter tracking.

  14. I have an existing side faucet from a previous system. Can I use that with my new Aquasana water filter?

    We recommend that you use the faucet provided. We have extensively tested the system with the faucets included. The faucets are NSF Certified to have no lead content. In addition, they will not impart any unwanted chemicals into your water. If you choose to use another faucet, we recommend that you have a plumber install the system to ensure no leakage occurs. We also recommend that you install an NSF Certified faucet to ensure the health benefits of your new Aquasana water filter.
