Rated 5 out of 5 by from Just installed and the like it The installation took about 30-45 mins. Was a simple process. The water flows does not seem to be impacted so much. Did you find a significant difference in the taste of water but definitely have a great feeling and peace of mind thinking about drinking pure water

Rated 5 out of 5 by from Well Water So far so good. We have pretty yellow well water and this has done an amazing job filtering it. The water is perfectly clear with great taste. We'll see how long the filter lasts with our poor water though.

Rated 5 out of 5 by from Great product at a great price Extremely pleased with the the filter. It was easy to install. I bought a some extra parts and installed it on my refrigerator. Made the water taste great.

Rated 5 out of 5 by from Significant taste difference, wow Real human unsolicited review! We're almost two months into the purchase and installation of our Claryum filter. It was an easy purchase, shipping was quick. Installation took about 30 minutes, most of which was me deciding where would be the best placement/configuration under my sink. But holy cow the difference in our water flavor and clarity is definitely noticable. With our old farmhouse pipes I knew there would be some taste improvement, and of course the health benefits, but I'm so pleasantly surprised just how much better the water through the filter tastes and smells. And, extra benefit, we did not lose any water pressure post installation! I'll update my review after 6 months/filter replacement. Thanks aquasana!

Rated 5 out of 5 by from Fantastic I wanted to wait a month before I did my review to give the filtered water time to show a difference on my 5 Bulldogs. I am happy to say that it has made a HUGE difference in their tear stains as well as their consumption. We can use the cold faucet now for cooking as well as we were using the fridge water for it’s filter. Overall I am super happy with this product and it’s installation was really easy!

Rated 5 out of 5 by from The best I’ve found We are really happy with this filter. It was very easy to pop under the sink and switching the replacement filters are even easier. The water tastes noticeably cleaner and ice cubes freeze clear. This is a great company and I searched for a long time. It’s the only filter that removes this wide array of contaminates. Customer service is excellent as well. Highly recommend.

Rated 5 out of 5 by from Easy Had a counter top power filter that was loud and started leaking, thought I would try the direct connect. Install was very easy took less then 10 minutes, works very well, does slow water flow but not a lot but you will notice it.

Rated 5 out of 5 by from Three Months in and Very happy The fact that I dont have to have an auxiliary faucet was important to me, but I also wanted max filtration. We love having filtered water from the main tap with strong flow so that we can easily use the water for cooking and to fill water bottle quickly. Easy installation - 30 minutes from opening the box to getting filtered water from the main tap.

Aquasana FAQs

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

    Our under sink drinking water filter systems are easy to install, and a plumber is not required. If you have any questions or need assistance, please call our Customer Support line at 866-662-6885.

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

    To keep your system working and prevent the growth of bacteria or mold, you should replace your filter every six months or upon reaching the specified gallon capacity, which is 784 gallons for the Claryum® Direct Connect (AQ-MF-1). The filter replacement cost is $69.99, or $59.49 with Water for Life®. Water for Life® is our no-contract filter subscription program that offers 15% off filter replacements, an extended warranty, and free shipping. Learn more here

  3. Is this purified water?

    No, filtered water can be healthier than purified water. Purified water undergoes reverse osmosis or distillation, which strips everything out of your water - not only contaminants, but also healthy, naturally occurring minerals. Our system uses Claryum® selective filtration designed to reduce up to 99% of 77 contaminants while retaining the healthy minerals like calcium, potassium, and magnesium.

  4. What's the micron rating of this filter?

    The Claryum® Direct Connect is designed to filter down to 0.5 microns.

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

    Since this system uses your existing faucet, there's no need for any drilling or modified plumbing. Simply attach the system to the cold-water line underneath your sink. It's also easy to remove and take with you to your next apartment or home.

  6. What is the size of the dual port adapter that attaches the water line?

    The dual port adapter supplied with this system fits 3/8" water lines. This is the most common water line size.

  7. Does this system remove fluoride?

    No, the Claryum® Direct Connect does not remove fluoride from your drinking water. If you're looking to remove fluoride, we recommend a reverse osmosis water filter such as the OptimH2O® Reverse Osmosis + Claryum®.

  8. What does TDS mean?

    TDS, or Total Dissolved Solids, is 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. Read more about TDS here.

  9. What is BPA? Should I be 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 found in tap water.

  10. Does having hard water mean it is contaminated?

    Water is considered "hard" when high levels of dissolved minerals are found within its makeup. 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?

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

  12. What is Claryum® Technology and what does it do?

    Claryum® technology is a selective filtration process that uses sub-micron filtration, micron filtration, adsorption, and ion exchange. Together, these technologies reduce up to 99% of 77 contaminants from water while maintaining healthy minerals like calcium, magnesium, and potassium.

  13. What is the difference between the Claryum® Direct Connect and the other under sink drinking systems?

    The Claryum® Direct Connect has the highest flow rate of any Aquasana drinking water filter at 1.5 GPM, while still removing up to 99% of 77 contaminants. It does not require a dedicated faucet, but instead can be used with your existing faucet. Other Aquasana under sink drinking water filters require a dedicated faucet. All of our under sink filters vary based on the number of filter stages used and flow rate. In some cases, the number of contaminants removed varies.

  14. I already have a dedicated faucet in my kitchen. Can I use that with my new Claryum® Direct Connect Water Filter?

    We've designed the Claryum® Direct Connect to give you fast, convenient access to clean, healthy water directly from your existing faucet. Although it's not the designed intent of this system, it can be used with a dedicated faucet. You will be required to separately purchase any parts needed for this type of installation. Unfortunately, we do not supply installation instructions for this type of installation.

Do you have to turn the water off to swap old for new cartridge?

Asked by: Sail
Hello Sail, Thank you for your question. Yes. We do ask to turn off the cold water supply under the kitchen sink before performing a filter change. After the new cartridge has been replaced, turn on the kitchen faucet to COLD water and run water through the cartridge at full force for at least 15 minutes. This action will purge the system of air and carbon fines ensuring maximum filter life. -Aquasana

Asked by: EveE
Hello Eve, Thank you for your review. Although it's not the designed intent of this system, the water can be directed to your refrigerator for filtered water. You will be required to separately purchase any parts needed for this type of installation. Unfortunately, we do not supply installation instructions for this type of installation. We highly recommend that you seek the assistance of a certified licensed plumber for this type of configuration. -ACS

I installed the Claryum Direct Connect this afternoon- the water flow level seems very slow compared to previously. I expect that there will be certain drop-off due to the filter system; how much of a drop-off should I expect?
