Aquasana Claryum™ filtration technology

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-4601 water filter, Aquasana Claryum™ filtration technology stands between you and the harmful contamination present in your water supply.



NSF-certified Aquasana Claryum™ filtration features three-stage technology to reduce pollutants and maintain healthy minerals to balance pH and ensure fresh, spring water flavor.

We reduce over 50 commonly occurring contaminants including:

  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 30 minutes to do; no plumber is necessary.
  2. What is the size of the brass T-fitting for under counter and premium under counter unit? — The most common size is 15mm which originally comes with the system purchase. In rare cases some customers may need an 18mm T-fitting which we can provide free of charge.
  3. What size hole do I need in my sink for the under counter and premium under counter systems? — 22mm to 38mm
  4. How often do I have to replace the cartridges and how much do they cost? — We recommend replacing the cartridges after six months or 500 gallons/2,300 litres, whichever comes first.
  5. 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.
  6. 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.
  7. 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.
  8. 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 UK and Europe are considered hard. Hard water is generally safe to drink, after it has been properly treated.
  9. 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.
  10. 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.
  11. What is the difference between the under counter and the premium under counter systems? — Just the faucet. The premium under counter faucet has a choice of finishes and a turn valve. The basic under counter faucet only comes in a chrome finish and has a paddle valve.

    Undersink Filtration System

    This is a very good filtration system that comes with its separate tap. The tap also looks very sleek and the flow is great. Its perfect for a household so that anyone can drink filtered water whilst the kitchen tap is in use.
