Your water becomes contaminated from a variety of sources throughout the process of collection, treatment and delivery. From groundwater contamination at the source to chemical contamination at the treatment facility to rust and lead contamination as the treated water travels through pipes to your home, the water you drink and bathe in can contain dangerous levels of harmful contamination. This continuing level of contamination makes filtering your water a critical component of maintaining your health. With the AQ-4000 Countertop water filter, Aquasana Claryum™ filtration technology stands between you and the harmful contamination present in your water supply.

The result is truly healthy, great tasting water for drinking, cooking, and preparing beverages at the convenience of your family's kitchen faucet for 11¢ a gallon on Water for Life!

Our NSF Certified AQ-4000 features patent-pending Claryum™ Filtration Technology to effectively reduce over 60 harmful contaminants while maintaining healthy minerals.

We reduce over 60 commonly occurring contaminants including:

Water under pressure means better filtration.

After devoting 18 months to redesigning and reformulating the company's filter cartridges, Aquasana has created its most powerful and best-performing filtration systems to-date. Unique in both design and functionality, the new Aquasana Claryum™ filtration technology features three distinct stages, including activated carbon, ion exchange and sub-micron filtration. Together, this unique combination forces water under pressure over more than two million square feet of surface area of contaminant-grabbing filtration material. In addition to reducing a comprehensive list of chemicals and contaminants, Claryum's™ patent-pending selective filtration technology reduces odor and improves the taste of tap water while also preserving its healthiest minerals such as calcium, potassium and magnesium for optimum hydration — which are vital for growth, development and overall health and wellness.

Aquasana drinking water filters cost less and provide better filtration.

1. Do I have to pay for a plumber to 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 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 450 gallons, whichever comes first. Replacement filters cost $59.99, 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.

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? — 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 AQ-4035 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. Which filter system should I get? — The countertop system is perfect for renters because it does not require a new hole in the counter. To install an under counter system, you can remove the existing sprayer or soap dispenser in your rental 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.

6. What size adapters do you send with the countertop system (for the diverter hose)? — 13/16 and 15/16 male.

7. What size is the chrome collar on the countertop system (on the diverter hose)? — 55/64-27 female.

8. What does TDS stand for, and what is TDS? — Total Dissolved Solids: dissolved minerals and metals. TDS meters tell you the concentration of dissolved minerals and metals in your water, but are not an accurate measurement for contamination. Aquasana products remove harmful TDS, like dissolved lead and iron, but since our selective filtration leaves in calcium, magnesium and potassium, and minerals are dissolved solids, there will still be a measurable amount of TDS in our filtered water.

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. How do I know if an Aquasana system will be compatible with my faucet? — 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. 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 and we will see if we carry the right size adapter, and we will send it to you.
