Rated 5 out of 5 by from Great Countertop Filter Easy to install, looks nice on my sink. Water tastes delicious, and it filters fast. A good feature is that the water is filtered and returns through a second line back to the faucet, allowing filling of different size containers.

Rated 5 out of 5 by from Water tastes good I have enjoyed this countertop filtering system. Easy to work & change filtering system. My health has changed some, not having to fill the container with water is paramount for me. It filters make the drinking water clean & very good tasting.

Rated 5 out of 5 by from Great Water Filter! I have used Aquasana filters for years now and don't drink water that hasn't gone through one. The filter removes unwanted contaminants but leaves desirable nutrients, even adds nutrients in the filtration process. Water tastes fantastic! Filters last long enough that the cost is reasonable. Installation has been a breeze - I even hooked up a counter-top filter to a spray faucet using a simple extension from a hardware store. This is a great multi-stage water filter!

My faucet does not have a screw/unscrew capability and is installed with a pullout hose/faucet. Will this still be compatible? Do you have other attachments?

Asked by: AndyM
Hello Andy, We appreciate your question. The only faucets the AQ-4000 water filtration system will not be compatible with are the 2-in-1 faucets that have a detachable sprayer at the faucet opening. The AQ-4000 will fit most standard faucets and also comes with two adapters. Unfortuatnely, we do not carry any other attachments that will fit a 2-in-1 faucet. -Aquasana

FAQ
Aquasana FAQs
1. Do I have to have a plumber install the system?
Our countertop drinking water filter system is 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 877-996-2875 can guide you through the installation process. Follow along with our helpful installation video.
The Claryum® Countertop filter is not compatible with 2-in-1 faucets that have a detachable sprayer at the faucet opening. The Claryum® Countertop will fit most standard faucets and comes with 2 adapters. If your faucet happens to be a non-standard size than the hose connection or adapters that come with unit, you can take your aerator to the plumbing section at your local hardware store and have it measured. After you know the size of your aerator, contact technical support with the size. If we carry the right size adapter, and we will send it to you.
The Claryum® Countertop system is perfect for renters because it does not involve drilling or professional installation. To install a countertop system, you attach the unit to your existing faucet. This filter will not damage or permanently modify your plumbing. When you move out, you can easily remove the system and use in your next home or apartment.
We recommend replacing the cartridges after 6 months or 450 gallons, whichever comes first. To eliminate the hassle of remembering when to change your water filter, sign up for our auto-ship program, Water for Life® Our no-contract program saves you 15% on filters, includes free shipping, extends your filter warranty.
Claryum® technology is a selective filtration process that uses sub-micron filtration, micron filtration, and adsorption. Together, these technologies reduce up to 99% of 77 contaminants from water while maintaining healthy minerals like calcium, magnesium, and potassium.
Due to the nature of the carbon blocks assembly and the contents of a used filter, the filters cannot be recycled.
No, this is not purified water, it is filtered water. Purified water undergoes reverse osmosis or distillation, which strips 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.
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.
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.
No, hard water is not always considered contaminated. Most water sources in the USA are considered hard.
Hard water can be city water or well water meaning it may or may not be pre-treated. The minerals that make water "hard" are not considered contaminants, but hard water can still contain additional contaminants that are not safe for consumption.
Soft water is water that has either been treated by a water softener or naturally contains less hard minerals. The most recognizable trait of "soft" water is how much more soap lathers, as opposed to hard water. Soap lathers less due to the higher concentration of minerals. Water softeners reduce the negative effects of dissolved minerals in water that can clump together and produce scale buildup.
Soft water does not mean clean water. Your water can be soft and still have contaminants present in the water.
Yes, soft water is considered potable. Drinking water from a sodium-based softener increases your daily intake of sodium, which can lead to health problems in sodium-sensitive individuals. Please keep in mind that a water softener is not a water filter. A water softener does not remove contaminants present in your water.
