Doe this filter unit is compatible to pull down kitchen faucet?

Asked by: clean_water
Thank you for your inquiry. No, the counter top system is not compatble with pull down/out sprayers. We recommend an Under Counter system or Clean Water Machine at https://www.aquasana.com/drinking-water-filter-systems

I've had my filter for few years. Now the water drips from the filtered water side whle the faucet is off. I've tightened it but that did not help. How can this be fixed?

Asked by: bluebass
Sounds like a new washer is needed which you may purchase at a hardware store. There is also plumbers thread seal white tape that can be wrapped around the screw mount. I also looked on the website and they do have replacement attachments that you can purchase for $15.99 or $27.96 if you need a pre-filter. That would probably solve the problem, too. Look under Water Filter Parts, Accessories. Sometimes things just get old and need to be replaced.

Premium Counter Top Water Filter System in White is rated 4.5 out of 5 by 496.
Rated 5 out of 5 by from Water tastes good Super simple to install and the water tastes great
Date published: 2019-03-12
Rated 5 out of 5 by from Will always have this countertop unit! The simplest to install. Make a tremendous difference in taste of water. Easy filter changes if you use the proper sized metric box end wrench. Easy leak stoppage with same wrench. Been using for many, many years. Aquasana would do well to include in the instructions the information about using the correct metric box end wrench or socket

Rated 5 out of 5 by from Worth the try! First sink-top water filter and so far, I'm loving it! I've tried others that are heavy and tend to have the whole component attached to the end of the faucet. After time, had to replace faucet due to the weight of the unit...so was thrilled to see there was an affordable sink-top version. Super, super easy to set-up...took less than a couple of minutes, easy to follow directions. I love the button that you use to change the water flow to the filtered water, if you forget to change the water back and shut the water off...the system shuts it off for you. The chrome filter unit is so sleek & you really don't notice it on your counter top. I was worried the water lines wouldn't be long enough, but had plenty of room. The water tastes great and I can't wait to start saving money but filling my own water bottles....WOO HOO! I would highly recommend this unit, I'm glad I have it. You'll be saying, too: "Worth the try!" Enjoy :)

Rated 5 out of 5 by from BEST COUNTER TOP FILTER I EVER OWNED! I have been using this model filter since about 2005. The water tastes great and I always feel confident my family is getting not only great tasting but healthy water!I use it to make iced tea, homemade soups, ice cubes, etc. Everything tastes better with filtered water. And I don't have to carry heavy cases of bottled water into my house and I'm not putting plastic bottles in the landfills which makes me feel more Green. It's a Win/Win situation!

Rated 4 out of 5 by from Love it Love the taste! Wish there was a way to lock filter to on when using sometimes turns off.

Rated 5 out of 5 by from Very Pleased From the very first glass, I could tell the difference. It is so good to know that I am getting healthy, clean water that benefits my overall health. Being on a fixed income, I needed to find a low cost solution to obtaining healthy water, and Aquasana had exactly what I needed. It took advantage of the water that I already had, so I didn't have to buy water or a dispenser. I am so thankful to have found out about this, and highly recommend it to everyone.

Rated 1 out of 5 by from Horrible design, incredibly hard to swap filters I've had this filter for almost ten years now, and the design has not changed since. I like the quality is water, however, prepare to lose your knuckles when the time to swap filters comes. After six months of use, caps get stuck, and it will be a nightmare to open them. Don't believe the customer support, recommending to use a wrench. It won't work. Since 1-inch bezel surrounds the filter, there is not enough space to grip the cap tightly. You can't use a socket since the connecting flow tubes are almost impossible to detach and will further complicate the process. If you somehow manage to grip the cap securely with a wrench key, the plastic will simply crumble once you apply the pleasure. I can't even explain how many times I've had my fingers all scratched to blood. Customer service will advise you to make sure to apply enough oil prior sealing the filter - IT WON'T HELP. I've had to order a replacement at least three times because the cap got stuck completely. So, bottom line - very affordable filter, produces good quality of water; however, the design and functionality are HORRIBLE. Mark my words, you will hate it when time to change filters comes. Last time was my final time using it, and I'm researching a purchase an under the counter, professional filter, although I know it will be more expensive. I have no more patience dealing with this product.
