Under Sink Water Filter System - Reduces PFAS, Lead & Chlorine

Our review of the Aquasana under sink water filter system finds it best suited for households that want fast, safe drinking water without removing beneficial minerals. The biggest reason to buy is its Claryum filtration that reduces up to 99% of 78 contaminants including lead, PFAS (PFOA and PFOS), chlorine, pesticides and more, while leaving calcium and potassium in the water. Installation is designed for a homeowner to complete without a plumber, and the included brushed nickel faucet makes it a complete under counter solution for everyday kitchen use.

Key Features

• Claryum filtration: Removes harmful contaminants while retaining healthy minerals so water tastes natural and not stripped.
• Certified performance: WQA tested and certified to NSF/ANSI Standards 42, 53, and 401 for verified reduction of common drinking water contaminants.
• High flow rate: Delivers about a half-gallon per minute so there is no long wait compared with slower drip systems.
• Long service life: The filter lasts up to 6 months or 800 gallons, keeping ongoing cost to roughly 10 cents per gallon.
• Simple replacements: Twist-off eco-friendly housing and tool-free changeover mean you do not disconnect hoses during filter swaps.
• Complete kit: Ships with the first set of filters, brushed nickel faucet and all parts needed for a typical installation so it is ready to use out of the box.

Who It's For

This system is a good fit for kitchens where municipal or well water contains chlorine, PFAS, lead or other common contaminants and the household wants immediate faucet access to filtered water with minimal fuss. People who value preserving natural minerals in drinking water will appreciate the Claryum approach, which targets contaminants but leaves calcium and potassium intact.

It is less appropriate for users who need to lower Total Dissolved Solids (TDS) or who require an in-line whole-house solution; this is an under counter point-of-use system intended for kitchen drinking and cooking water only. Also check your sink layout before purchasing if you plan to use a nonstandard installation location.

Pros & Cons

Pros

• Effective reduction of a wide range of contaminants including lead and PFAS while keeping beneficial minerals.

• Cost efficient filter life at about 800 gallons or 6 months and straightforward, twist-off replacements.
• Comes with a brushed nickel faucet and all parts for a typical install-no plumber required for most users.

Cons
